Heat Pumps

Heat Pumps are electrical devices that extract heat from the environment and converts it to a higher temperature to provide heat and hot water in your home, via a refrigeration cycle. (Eg. Fridge & AirCon in reverse).

The Heat Pump works most efficiently with low cost heating systems such as SmartRads and underfloor, which can heat your premises effectively at lower water temperatures than conventional radiators.

Air to Water (Air Source Heat pump) is the most popular and as it does not require underground piping can be cheaper and easier to install. See figure 1.
Air at -5°C contains approx 85% of the heat it contained at 21°C, showing a heat pump can supply heat to a house even on cold winter days.



  • Reduce your energy costs immensely
  • CO2 emissions cut in half
  • 12 – 20 year life span
  • Less maintenance
  • Safer than conventional heating system
  • Can be controlled remotely via smart phone
  • SEAI Grants of up to €3700

A heat pump typically produces 3 – 4 units of heat for every 1 unit of electricity consumed. Making a heat pump 300% efficient in comparison to Oil or Gas at 90% therefore, a smart investment.

The heat pump example in Figure 2 has a Coefficient of Performance (COP) of 4.

Example of Annual Cost of Heat Pump – A house using 25,000 kW hrs of energy, average seasonal C.O.P. of 4 and electricity cost at 50% Night Rate, 50 % Day Rate*

Heat Pump = €945

Gas/Oil = €2,682

Annual Savings = €1,737


ASSET is an approved installer with Mitsubishi Ireland therefore, the heat pumps we install are covered via manufactures warranty.

The Climate Action Plan commits Ireland to installing 600,000 electric heat pumps to replace fossil fuel home heating. In 2018, 90% fossil fuels were still used for energy. Help the transition away from burning fossil fuels – lets go carbon neutral.
