Heat Pump and CHP Specialists

Heat Pumps

Ground source heat pumps transfer heat from the ground to your house from water-filled pipes in relatively shallow trenches or inserted down a borehole. Air- and water-source heat pumps take their heat energy from a flow of air or water. Moderate underground or ambient air or water temperatures warm chilled water or refrigerant and are then, using a refrigeration cycle, transferred to a heating system and used to heat domestic hot water. Heat pumps work best with underfloor heating systems operating at lower temperatures than conventional radiator systems and therefore tend to be better suited to new-build installations. A typical system will cost between £7,000 and £13,000 net of a grant and with the proposed Renewable Heat Incentive (RHI) could save over £1,500 per annum. Whilst heat pumps are retro-fitted into older buildings, great care must be taken and all possible energy efficiency measures implemented if they are to be cost-effective.

Combined Heat and Power (CHP)

Combined heat and power, whether from natural gas or renewable energy sources, represents a great increase in energy efficiency compared to conventional electricity generation where two thirds of the primary heat applied to the process is wasted up a chimney. Good quality combined heat and power systems, where the heat is used to heat buildings or provide heat for a production process, should benefit from both the feed-in tariff and the proposed Renewable Heat Incentive and are placed to become as popular as they already are in many European countries.
