Comments on: Geothermal Heat Pump Systems’ Contributions Towards Emissions Reductions

With closed loop geothermal you get help pumping up from gravity sucking down.

If you size the hose/pipe large enough for the flow then you minimize the energy needed to move liquid.

Hydronic floors also require pumping liquids so there’s no gain there on ground source heat pumps. Plus, in cloudy/snowy areas solar collectors are not going to function all that well, requiring a fossil fuel backup system.

Masonry/wood stoves are good options for some, but we don’t have the wood to heat everyone’s home and there is the additional problem of soot/carbon black which is an additional contributor to global heating.

Electricity can be generated ‘clean’. Use clean electricity to pump water through a heat pump and you’re creating no CO2 or soot.

GSHP are great in that they are very efficient.

However, I invite you to calculate the amount of electricity required to pump liquids continuously up and down or sideways.

There are other less conventional ways of cooling and heating which require less electricity.

Masonry stoves, hydronic floors linked to solar water collector panels ( even in winter with lower delta) and wood stoves.

There is a very fun and informed book Im currently reading called Geothermal HVAC. This is an amazing book that really helps you understand the science and principle of how the earth can better heat and cool your home while saving you more than a standard heat pump.

@Mac: This is a guest post by an expert in the field. We have done these in the past as well. Geothermal is a great energy source and we greatly appreciate experts on the matter writing on it for us. I’m sorry if it turns you off. (We receive nothing for publishing it, of course.)

First advertorial I’ve seen here. Bad precedent.

As a LEED AP, I am finding great success specifying geothermal heating for my clients. Whenever a customer begins to question the merits or the actual efficiencies, we give them McGraw-Hill’s book on Geothermal HVAC. We haven’t had anyone question us since we started that policy. The fact is that geothermal heating and cooling is no longer magic; it’s for real, and it’s here to stay. Google “Geothermal Book”
