What does Daikin Ireland offer that is different to other
                      manufacturers:

• Irish based office with 20 staff members for sales & technical support

      • EDC – European Development Centre and testing rooms

• Heat Pumps Solutions for Domestic and Commercial for both new and

Renewable energy is derived from natural
What Is     processes that are replenished constantly.
Renewable
            In its various forms, it derives directly from
Energy?     the sun or from heat generated deep
            within the earth.

            Renewable energy can be used to generate
            electricity or produce heat.
A heat pump is an environmental energy
technology that extracts heat from low
temperature sources (air, water, ground),
upgrades it to a higher temperature and
releases it where it is required for space
and water heating.
From April 2018 – SEAI Better Energy Home
Heat Pump Grants
€3500 grant for an Air-to-water, Exhaust-air or Ground
source heat pump, providing will cover 100% the
heating load and 80% the DHW load
€600 grant for a Air-to-air heat pump, as above
€824 from Electric Ireland grant (as it stands)
€170 switching bonus, Electric Ireland from one provider
to them.

What Is A Heat Pump?
How does a heat pump work?
Have I got a heat pump at home?

                                                        “
                                                         “A fridge is a heat pump”
• The inside of the fridge is kept cool by extracting energy from inside the fridge.
• This energy is then rejected to the kitchen ( if you put your hand behind the fridge it
feels warm)
          An air source heat pump doing heating works like a fridge in reverse!
Benefits of the ASHP: for 1kW consumed produces on average 3-4kW=400-500% efficiency

New-build – ideal
 > Building well-insulated, small heat loss
 > Heating distribution
                     system can be

Aim for lowest possible water flow temperature
to achieve
   >   Highest SCOP
   >   Lowest running costs
   >   Lowest CO2 emissions

Fan assisted radiators               Water filled radiators
Emitters:
underfloor heating
Works best with heat pumps
Provides near-ideal heat profile with:
warmer at foot level, cooler at head level
Large surface area so can operate at low
flow temperatures – as low as 30oC
Temperature in a room heated by UFH can
be 2oC lower than one with radiators to
achieve the same comfort levels
Avoids large, unsightly radiators
Great for tiled floors and modern floor
finishes
No draughts, less dust transport
Emitters:
radiators

Most common form of heating
Typically designed for water temperature of 70oC
or more
Obtain correction factors to size at lower water
temperatures
Low temperature radiators up to 45deg flow
Steel panel and aluminium radiators suitable for
temp applications
No radiators covers to be used, as it reduces the
output of the radiator

Mechanical ventilation and exhaust-air DHW heat pump
   With the mechanical ventilation function of your heat pump you can ventilate your home
   and use your polluted inside air to make your heat pump function.
How does it work?
         I.      Polluted inside air is extracted                          Polluted warm air from
         II.     The air is transported to your heat pump.                 ventilation system
         III.    Heat is extracted from the polluted air.
