Heat Pump Boilers – Underfloor Heating
Heat Pumps have been known for some time to provide highly efficient cooling. Mitsubishi Electric has now designed a heat pump boiler which provides hot water suitable for under floor heating.
An air conditioning system that extracts heat from space will normally achieve an energy efficiency of up to 4.0 COP. However by utilising a heat pump boiler this heat is recovered and used to heat up water, increasing the COP to over 6.0. The efficiency of a heat pump boiler is particularly recognised in spring and autumn, when different rooms may need to be heated and cooled from the air conditioning system at the same time.
Benefits of Heat Pump Boilers
- Permanent heat recovery all year round
- Reductions in running costs
- Reductions in C02 emissions
- Improved carbon footprint
- Easier to get planning permission under Part L2 legislation
- Reduced capital costs
Heat Pump boilers - Capital Cost Reduction
There is a reduction in Capital Cost as there is no requirement for a gas supply and gas boiler. The heat pump will heat the water to 45 degrees and the boost to take it to 60 degrees can be provided by electric means.
