Ground source heat pumps are the most efficient of the three types of heat pump available through Nu-Heat. Pipes are buried either in trenches in the ground or in a vertical borehole where heat is extracted and passed through the refrigerant cycle of the heat pump, compressed and made available for the domestic hot water and space heating requirements of the property. Ground source heat pumps can assist in achieving CfSH Levels 3, 4 & 5. [ read more ]

If there is insufficient land available to install a ground source heat pump, an effective alternative is to use an air source model. Although not quite as efficient as a ground source heat pump, the expense of installing pipes in the ground or using specialist contracts to excavate boreholes is removed. Air source heat pumps can assist in achieving CfSH Levels 3 & 4. [ read more ]

The exhaust air unit is typically used on smaller houses and apartments. It operates by extracting the latent energy from warmer areas of the property such as kitchens and bathrooms via ductwork and passing it through the refrigerant cycle of the heat pump where it is compressed and made available for domestic hot water and space heating. Exhaust air heat pumps can assist in achieving CfSH Level’s 3 & 4. [ read more ]

During daylight hours the sun’s radiation warms the earth – even when the sky is overcast; this energy can be captured and used to heat water. Most households can generate up to 100% of their domestic hot water requirement in the summer, but the percentage falls during the cooler months giving an average annual provision of up to 60%. Every Nu-Heat quote states the estimated annual proportion of hot water the solar collector will supply based on the individual demand for the household. In conjunction with any of the above heat pumps and underfloor heating, this free and renewable energy can help to achieve higher levels of the CfSH. [ read more ]

Underfloor heating works by pumping controlled flows of warm water from any heat source through plastic tubing embedded in the floor. Because the emitting area is large, sufficient warmth is provided even on a cold winter day with no need for supplementary heating.

Underfloor heating is the perfect partner for any heat pump system. Its benefits include design freedom – with no intrusive radiators taking up valuable wall space – and a reduction in dust mites for a healthier living environment. The low flow temperatures needed for underfloor heating (as opposed to the high temperatures of standard radiators), allow maximum efficiency of the heat pump to be achieved. [ read more ]
