In your first comment you did not specify that you had electric HEAT PUMP before you installed Geothermal Heating.

My assumption was based on the fact that 99% of all heating systems use some sort of fossil fuels – even electricity comes from coal or gas most of the time, and electric baseboard heat is the most expensive type of heat. Therefore my assessment was based on this assumption.

Heat pump, be it a non-geothermal as in your case is already “efficient”, and is very popular in Northern Europe (Finland / Sweden / Norway). So you are comparing to efficient hearing systems against each other, and in your case the geothermal also comes with the water pump that must circulate heat exchange liquid through the loops.

Now I do not know all the details about your geothermal system – maybe there is an issue with design or installation – I don’t know. Maybe you should try calling a different Geothermal contractor or get an energy audit from your local utility company (these are usually free).

Bottom line – geothermal should be more efficient that just pure heat pump. However, like I said – maybe it’s a faulty system design, or maybe the loops were laid wrong, or there is not enough loops (undersized system) or maybe something else. Get a second opinion from local professionals.

Good luck.

Of course I did NOT expect it to be free. I would be thrilled with 25% of my prior heating / cooling energy consumption.

Do you have a different assessment now?

Regards.

Think about it: Geothermal is essentially a heat pump, a water pump to circulate the heat exchange liquid through the loops, and a fan to distribute the warm air through air ducts. ALL operate using electricity!

What you get in return – you do not use OIL / GAS / ELECTRICITY to heat / cool your house directly. The benefit is that you are using only about 1/4 of the energy in dollar terms.

Did you expect to eliminate use of oil / gas and that have geothermal system operate for free???

I agree with the installer – everything is fine, unless I am missing something or you did not provide additional information.

Even in regions without large high temperature geothermal resources, a geothermal heat pump can still provide space heating and air conditioning.

Thanks,

For layout diagram of geothermal heating and cooling system, it is best that you contact a manufacturer of Heat Pumps, such as Water Furnace.
