The cost of a heat pump is from ?250 thousand. For comparison: an electric boiler costs from ?15 thousand, a gas boiler for a private house - from ?60 thousand, not counting the gas supply to the house (which in some cases takes years, and can be much more expensive than the entire geothermal project). Sometimes the cost of drilling wells for the primary circuit of a heat pump is more than 50% of the cost of the entire project.
According to the World Bank, the cost of conducting exploration work and an initial pilot drilling C Level Contact List program for three to five geothermal wells is between $20 million and $30 million. Low system efficiency for traditional radiators. In case it is necessary to obtain a high temperature in the secondary circuit, heat pumps show less efficiency compared to traditional heating systems. Thus, they are better combined with the currently popular "warm floor" heating system: where the heat carrier is required to have a temperature of 45 º? than with traditional batteries, the system of which requires the heat carrier to be.
Not effective enough in cold climates. Heat pumps are more efficient (show higher efficiency) in winters - with negative temperatures down to -20 º?, and in some regions even up to -40 º?. In the case of heat pumps, the higher the efficiency, the smaller the temperature difference between the inlet and outlet of the heat pump. For example, other things being equal, let's compare winter in Paris and in the Moscow region. The air temperature in Paris in winter is about -3 º?, and the ground temperature is +10 º?, the difference.
