What are thermal-earth heat pumps

Basically a geothermal heat pump is essentially a fridge, and the warmer the cold part of the fridge is kept – the evaporator, the more heat it gives out on the hot part – the condenser. The water is taken from the ground, travels through specially designed heat exchangers and keeps the evaporator the same as the ground temperature. Thus the condenser increases in temperature and efficiency. It is the heat generated by the condenser that we use to warm our heating system. 

• Water taken from natural sustainable sources ie. wells, boreholes, rivers or even the sea
• Up to 400% more efficient than conventional heating systems and up to 76% cheaper to operate if used with other Energy Efficient systems. 

What is needed to run a thermal-earth heat pump?

Thormec Uk's geothermal thermal-earth heat pumps are designed to run from a water source, so a supply of water is essential, for example: river, well or borehole. You will need to guarantee at least 1.5 litres of water per minute of running time for each kw of heat output, so for example: a 25kw unit will need to have at least 30 litres of water per minute for a maximum of 4 hrs per day. For this 25kw unit, the max to be used would be 4 – 8 cubic metres of water in a 24 hr period. 

• Within extraction guidelines from the Environment Agency.
• No need for extraction permits.
