5 Why Heat Pumps? Finally, you can control the cost of your own heating Heat Pumps, most notably air source heat pumps, are fast becoming the most popular renewable heating source in the UK. To date, around 30,000+ MCS accredited air source heat pumps have been installed in the UK since 2009. Though heat pumps require electricity to run, the way that they utilize this electricity means that they are a very cost effective and environmentally friendly way to provide your hot water and space heating requirements all year round.
Chances are, you already have a heat pump in your own home, in the form of a refrigerator. A common misconception is that a refrigerator makes things cold…. What it actually does is to take energy from inside the fridge and transports it to the back of the fridge, hence why if you touch the coil on the back of your fridge, it will be warm, whilst the inside of the fridge is cold. If we reverse the operation, and apply it to an air source heat pump, you will find that the inside of the fridge now becomes your garden and the warmth on the back of the fridge is now the heat circulating around your pipework to your radiators / underfloor heating.
The area directly in front of the heat pump will be much cooler than the rest of the garden because that energy is being transported into your property via the vapour compression cycle. Essentially, what is happening is that unusable energy from outdoors is being transformed into usable energy for indoors.
Air source heat pumps require electricity in order to power the compressor, circuit boards, circulation pumps etc.. For every 1kW of electricity used by the heat pump unit itself, it will provide around 4kW of heat. That means that 3kW of heat is being provided completely for free so you could say that a heat pump is around 400% efficient. If you compare this with a traditional gas boiler you will see that for every 1kW of energy used by the boiler, only around 90% of the fuel is used for heating. The rest is sent to the atmosphere via the flue. If you combine a heat pump with a SOLFEX PV system in order to offset some of the heat pump electricity usage, the running costs of the heat pump reduce even further and if you can also install a SOLFEX Solar Thermal and Underfloor Heating system you truly have a whole house solution.
As well as being one of the most efficient forms of space heating available, an air source heat pump installation may also attract a government subsidy in the form of the Renewable Heat Incentive. For a 4 bedroom semi-detached property this could equate to around £1000 a year in guaranteed index linked payments *Based on an average 4 bed detached property Heat Pump Savings £0.00 Coal Savings per year RHI Income per year Gas Electric Oil LPG £700 £1,400 £2,100 £2,800

When specifying a heat pump system for any building, key bespoke requirements of the building need to be taken into account such as: • Project Reference • Site Location • Floor Area • Age of Building • Number of Bedrooms ( If applicable) • Domestic Hot Water Requirement ( If applicable) The above are just some of the details we would require in order to approximately specify and dimension a heat pump system. In order to specify the system accurately, SOLFEX energy systems can assist you with the completion of the BS EN 12831 heat loss calculation in line with the requirements for RHI and MCS.
We have special tools and calculators built to assist with all aspects of the heat load calculation process. Heat Pump Engineering Support • Pre-installation & on-site installer support / consultancy by our trained professionals • Sample hydraulic and electrical layouts for many systems • Indemnity of the system design and specification • Commissioning & on-site installer support throughout installation can be provided. Enquire for further details.
Customer Service & After-sales Support At SOLFEX energy systems customer support & service does not end when you have purchased & installed your system. Our dedicated internal technical support team will ensure your enquiry will be dealt with professionally and in a timely manner. Dedicated On-Site Support Further to our dedicated internal team, we also have a team of external technical sales engineers who can provide on-site technical support to MCS accredited installers and consultants to ensure that projects are specified and installed as trouble free and as efficiently as possible.
7 Training SOLFEX energy systems pride ourselves on the support and customer service we offer.
In order to ensure that the specification and installation of your new heat pump is as smooth as possible, we offer full training for our entire range of heat pumps at various locations in the UK. All training courses are divided into two very distinct parts and are always held over a single day so as to ensure that the impact on your business is kept to an absolute minimum. All training courses are delivered on live installations to make sure that your experience is as relevant as possible. Part 1 – System Design and Unit Specification Heat Pump design and specification is very different to traditional fossil fuel heating sources.
There are a number of different considerations which need to be taken into account prior to installation.
Part 1 of the heat pump training encompasses such topics as: • What is a Heat Pump and how it fits to a property • Heat Pump Location and Drainage Requirements • Overview of Circulation Pump Sizing • Heat Pump Optimized Domestic Hot Water Cylinders • Emitter Circuit Considerations for Radiators and Underfloor Heating • Alternative System Design including Hybrid Systems • Explanations of SPF and COP efficiencies • Available Incentives • What is MCS? • Calculating the Heat Load of a property to relevant standards • Electrical and Mechanical Considerations Part 2 – Installation and Commissioning The installation of a heat pump is very similar to that of a traditional fossil fuel boiler.
The most evident difference is in the controls and commissioning of the system. If these are not treated with the utmost care, a very efficient system can quickly become inefficient.
Part 2 of the heat pump training encompasses the below topics: • Live Installation Component Overview • Full Commissioning Walkthrough After Sales Support SOLFEX energy systems understand that training does not begin and end in the classroom. With this in mind, we provide an unparalleled level of after sales technical support to ensure that all topics learned in the classroom can be successfully implemented in the field. As you leave the classroom you will be given two points of contact for dedicated technical support meaning that should you require assistance it will always be available.

9 Prestige Heat Pump Packs Prestige Packs Prestige Components Heat Pump Accessories Unvented Cylinders Pre Plumbed Cylinders Buffer Tanks
10 Prestige Heat Pump Packs All SOLFEX energy systems air source heat pump prestige packs are designed with the installer in mind. In order to ensure that installations are as simple and as straightforward as possible, many packs have been hand crafted to allow for around 95% of the components you will require on site. As we only use the highest quality components, which are engineered to compliment the heat pump they are applied to, you can be sure that ordering a SOLFEX prestige pack guarantees you a peace of mind installation.
To further add to your peace of mind, many packs are delivered on a single shipping pallet and packed so as to ensure that they are safe and protected in transit. SOLFEX energy systems has long held a deserved reputation for promoting only the worlds leading manufacturers in relation to the main equipment we supply. This reputation however does not end at main products. We have, and always will, ensure that only the most suitable and highest quality components are used to compliment our range of Heat Pumps.
11 When supplying around 95% of the equipment required by an installer on site, we have to be sure that the quality of the components will not negatively influence the installers perception of the main product, or indeed SOLFEX as a whole.
In order to ensure this confidence in our components is well placed, we only source our equipment from Europe. This ensures that we have full traceability back to manufacturer for anything as small as a single brass nipple through to something much larger like a buffer tank. Our involvement in components does not simply end at sourcing them. SOLFEX are also heavily involved in the design of many of our components. In fact, much of the equipment you will find in our prestige air source heat pump packs can only be purchased through SOLFEX due to our continued and trusted relationship with our existing supply chain.
12 Prestige Heat Pump Pack Components Heat Pumps Japanese, Korean and UK manufactured heat pumps from some of the biggest brands in the world. Each manufacturer possesses equipment which fulfils a specific requirement in the UK market. Pre Insulated Flexible Hoses When installing a monobloc heat pump, one of the biggest issues is ensuring that valuable energy is not lost from the pipework as it exits the heat pump and enters the building. This run may be no more than a metre, but it is extremely important that only the highest quality insulation and flexible hoses are used.
Anti Vibration Feet When mounting a heat pump on the ground, it is very important to ensure that it is sufficiently anchored and stable.
Providing a separation between property and heat pump is also extremely important to ensure that customers are not adversely affected by noise. 2 Port Valves 2 port valves perform a very simple function; to deny or allow flow. The beauty of our Spanish made valves is in their design. A very simple but effective motorised opening system ensures that unlike many other 2 port valves, these are flexible enough for a wide variety of heat pumps without the worry of unwanted flow related error codes. Control Kits In order for any of the SOLFEX supplied heat pumps to work correctly, they require a very specific set of controls.
Each control kit is designed to be as straightforward to set up and commission as possible Isolation Valves The means of hydraulically isolating the outdoor heat pump unit from the rest of the heating system is a task which should only be left to the highest quality isolation valves. SOLFEX full bore lever arm isolation valves ensure the absolute minimum resistance when open, and a secure leak free confidence when closed.
13 Flow Meter No heat pump can be accurately commissioned without the use of a specific flow meter. SOLFEX flow meters not only provide an accurate way to measure the flow through the system, but they also provide a means of correctly filling the system through the integrated ¾” flush and fill ports. Tyfocor Propylene glycol is very important in order to guarantee the continued operation and lifespan of your air source heat pump. For the manufacturers which require glycol to be added to the system as part of their warranty conditions, SOLFEX provide only the most trusted food safe propylene glycol.
4 pole isolator switch To protect yourself and your customers, it pays to ensure that electrical isolation is handled by a world leader in electrical switchgear. Our German manufactured isolator switches by Kraus and Naimer are among the best in the world. Brassware In order to ensure that small components are not the cause of negative perceptions towards the heat pump packs or SOLFEX in general, only the best Italian manufactured brassware is included in our packs. All brassware is manufactured to ensure the best possible seal.
Installation specific literature Together with around 95% of the components you require on site, we also provide comprehensive installation and commissioning instructions for a wide variety of installation types.
Whilst generally, installations will be very similar, having a dedicated manual which outlines the specific wiring and controller setup can make a huge difference to an installer in terms of cost and time. All literature is backed up by our internal technical support team should you have any questions.
Magnetic Filter Nothing will damage a heat pump’s plate heat exchanger quicker than metallic sludge present in the heating system. All systems should be power flushed prior to connection, but it only takes a few microns of metallic sludge to render a heat exchanger inefficient. SOLFEX magnetic filters are proven in the field to ensure that heat exchangers remain efficient and problem free. Buffer Tanks Many heat pump manufacturers now insist on the use of buffer tanks in order to ensure that the correct volume of water is available to the heat pump at all times. Where applicable, our prestige packs provide buffer tanks which are sized specifically in line with the manufacturers instructions.

15 Flexible Hoses When connecting from the heat pump to the property services it is always advised that a set of stainless steel EPDM lined flexible hoses are used prior to connection to rigid pipework. Our flexible hoses are manufactured in the UK specifically with air source heat pumps in mind. The bend radius of the hose is more than adequate to accommodate the installation dimensions associated with a heat pump. Pipe Insulation Poor insulation can considerably increase the running costs of an air source heat pump system. In order to limit these parasitic heat losses it is vitally important that high quality insulation from a trusted brand is used.
SOLFEX exclusively supply HT ARMAFLEX Foamed EPDM rubber insulation in many pipe sizes and thicknesses. Low Loss Headers In order to ensure that there are no flow issues between the heat pumps hydraulic requirements and the emitter circuit, in many cases it is advisable to employ a low loss header. One such instance is when utilizing a heat pump on an underfloor heating circuit which requires a difference in flow and return temperatures of 10 degrees, whilst the heat pump circuit will require a 5 degree temperature difference.
Hand Held Refractometer When commissioning many air source heat pump systems, it will be vitally important to ensure that the concentration of glycol in the system is at the level required to provide the expected protection down to a specific ambient temperature. The only accurate way to measure glycol concentration is through the use of a refractometer. SOLFEX provide only the highest quality refractometers to ensure an accurate reading. Through Wall Kit Running pipework from an externally mounted air source heat pump into a property requires the pipework to run through the exterior wall.
The hot pipework will be affected by cold bridging and heat loss if it is not insulated correctly. The Through Wall Kit provides both thermal insulation within the wall complete with elbow section to cover the copper connection.
Wall Mounting Brackets These flat-packed, self assembly brackets provide a professional finish to the installation of wall mounted outdoor condensing units and air source heat pumps. The Type 2 brackets have a crossbar allowing the uprights to be spaced exactly as required, and include wall spacers to help level the unit on uneven walls. 3 Port Diverter Valve Our Spanish manufactured 3 port diverter valves are specifically manufactured for use with heat pumps. Being a true diverter valve and not a mid position valve, there is no danger of supplying heating in the middle of summer when the hot water cylinder is being satisfied.
Filling Station When commissioning a system, it is imperative that a high quality filling and flushing station is used (in conjunction with an appropriate sanitizer solution) in order to ensure that pipework is bacteria and contaminant free prior to final filling. Once bacteria free, a high pressure fill is required to ensure that air does not remain in the system. The Solarcheck Mobilcenter from SOLFEX is perfect for this task.
16 Unvented Cylinders Solfex are proud to offer a complete range of unvented stainless steel cylinders specifically for heat pump applications providing mains pressure domestic hot water. Utilising an already well established stainless steel unvented hot water cylinder, this product has been developed to maximise the lower temperatures available from the heat pump. The heat exchanger is a totally new design. It consists of a multi-pass corrugated stainless steel tube in parallel to reduce the pressure loss whilst maximising the heat exchange. Many medium to large heat pumps need heat exchangers in the store that will cope with the higher flow rates associated with primary temperatures that are typically 50˚C or 60˚C.
Due to the fact that many heat pumps will not raise the stored water temperature to 60˚C, which is necessary to prevent the growth of legionella, the SOLHP range of cylinders are supplied with an immersion heater and a thermostat.
Duplex Stainless Steel The latest high specification Duplex stainless steel resists all forms of corrosion including crevice and stress whilst its high mechanical strength gives it durability. The very latest automated welding procedures along with full post weld treatments guarantee welds that are as strong as the metal. All cylinders are factory pressure tested to a full 12 bar which is four times the normal working pressure. Quality Standard All SOLHP cylinders are manufactured in accordance with BS EN 12897 the specification for unvented water storage vessels. The cylinders have been tested by NSF-WRc and WRAS, and found to comply with Building Regulations G3 and Water Regulations.
In performance, it complies with the requirements of BS EN 806-1 to 5 and meets the NHBC criteria for domestic properties. Our manufacturing partner also operates a quality management system audited and accepted by the BSI in accordance with BS EN ISO 9001:2008. Special features • The latest and highest quality Duplex Stainless Steel • 25 year guarantee. • Fast reheat rate from its purpose designed low resistance coil. • One of the highest insulation ratings on offer today. • The Stainless Lite HP SOL is supplied with all the necessary connections including two dry thermostat pockets.
Corrugated Stainless Steel Coil SOLHP cylinders use a high heat transfer corrugated tube heat exchanger to give a 20% faster recovery than plain tube.
It is also lighter and stronger than plain tube making the vessel the lightest and easiest to handle on site. Heat Loss All SOLHP cylinders are manufactured using the very latest HCFC free EnviroFoam insulation. This has an Ozone Depletion Potential (ODP) of zero and an industry leading Global Warming Potential (GWP) of 0.7. Tests show that the 50mm of EnviroFoam insulation injected into the case and covering both domes achieves astonishingly low levels of heat loss, which ensures it is fully compliant with 2010 Part L requirements for both new build and replacement cylinders.
25 Years Guarantee The 25 year guarantee underlines the confidence the manufacturer has in its own products.

20 Buffer Tanks Special features • Manufactured in the UK • Exceptionally Low Standing Heat Losses • 9 Connections on vessel as standard • Smart Attractive White Cased Unit • 25 Year Warranty on Vessel • Inspection Hatch for maintenance SOLFEX energy systems multi connection Buffer Tanks assist in remedying many heat pump installation issues. To increase the lifespan of key heat pump components, as well as to ensure that potential flow related issues are not applicable, SOLFEX Energy Systems in partnership with their UK based manufacturing partner are proud to offer a flexible solution to a multitude of installation types.
Many heat pump manufacturers have a specific requirement for minimum water volume in order to increase the lifespan of the units compressor. In some cases, this can be far above what would normally be present in a heating system. In this instance, a SOLFEX buffer tank can provide the much needed dedicated system volume.
As the name buffer suggests, these tanks are also extremely capable of storing energy for multiple uses. This energy may be required when the heat pump goes into defrost mode or even when it is serving domestic hot water. Every minute that a heat pump is serving domestic hot water is a minute that the heat pump is not providing central heating. A buffer tank can assist in tackling this problem.

24 Case Studies Installation Company: EST Renewables Limited Property Type: 4 bedroom detached Retrofit Location: Hutton, Preston Suburbs Heat Pump: AEC 9e Design Temp: -2.2°C Insulation Levels: High (High Specification Cavity Wall Fill and Loft Insulation) Heat Load: 12kW (8kW Covered by Heat Pump) Hybrid Heating Fuel: Oil Boiler Solar Thermal Installed: 4 x FK250 Heat Emitter: Underfloor Heating The detached property in Hutton, Lancashire had already benefited from the installation of Solar Thermal a couple of years previous and with continually increasing oil costs, Mr Givens decided it was time to look at alternative central heating sources.
Because Mr Givens wasn’t 100% sure about completely removing his oil central heating boiler and replacing it with an air source heat pump system, the decision was made instead to utilize an AEC heat pump in conjunction with the existing oil boiler. The most cost effective way to treat this installation was to use the existing boiler to serve the domestic hot water, whilst the heat pump would serve around 80% of the heating requirements for the property. The intention is that the boiler will only ever be used for central heating when the temperature drops below around 0°C. This ensures that the lions share of the heating can be delivered from the heat pump.
The high specification radiators installed were already adequately sized for the lower flow temperature available from the heat pump.

33 Installation Company: EST Renewables Limited Property Type: 4 bedroom detached new build Location: Buckshaw Village, Preston Heat Pump: Hitachi RHUE3.0AVHN1 Design Temp: -2.2°C Insulation Levels: High (New build insulation levels) Heat Load: 6.5kW Previous Heating Fuel: None Solar Photovoltaics Installed: 16 x 250wp Enhance Photovoltaic P60M Black Modules Case Study When Mrs O’Donnell was designing her new property, she decided that the perfect compliment to the PV system that was to be installed on her property would be a heat pump.
However, because of the lack of garden space, ground source was immediately removed from the equation.
This left an air source heat pump as the most viable piece of equipment to install. Provision had already been made to ensure that the radiators installed in the property were much larger than would be traditionally installed. This ensured that the heat pump installation would be able to run at a comfortable 45°C even at the coldest points of the year, without flow temperature back up from another heating source.
Whilst financial incentives were not the driving force behind looking at renewable heating, the renewable heat incentive payments were a welcome bonus. At the present time, without the benefit of inflationary percentages, the air source heat pump system will benefit Mrs O’Donnell by £670.00 per annum. Based upon fuel savings and RHI payments on the air source heat pump alone, the payback will equate to around 10 years which has far exceeded the customers expectations.
