Geothermal energy could be potentially transformational for our power grids, as we saw in our last video. But you and I can also get in on the act by drawing our own domestic heating from beneath our gardens (or communal gardens if you live in an apartment block). The technology is called a Ground Source Heat Pump. They've been around for a while but they are growing very quickly in popularity and may prove to be one of the lynch pins in helping us get to carbon neutrality by 2050.

Here in Finland heat pumps are very common and it is a no-brainer when building new houses. We also use central heating, my apartment is heated partly by the local metal industry, capturing their waste heat to low pressure steam, which is then piped to the town and used for heating. Also, trash burning is used for this, it is high flow, high temperature furnaces using monoxide recycling and carbon scrubbing. It is hot enough to return plastic etc back to their most basic elements and compounds, it is quite clean process, most of it is CO2, water and nitrogen. Trash is separated here so what ends in the trash burners is single use plastic, cardboard that is soiled or unsuitable for recycling, food packaging and other such household waste that would end up in landfills.

I installed one of these systems 25 years ago. I like the bore hole method because in the UK there are pipes and other forgotten obstacles that may cause problems. I think this system works best with under or in floor heating. In a floor system, the water temperature is a low 27deg C rather than 70ish for a radiator system. So, the heat pump doesn't have to work as hard and is more efficient.

It is always a pleasure to listen to a guy who knows how to explain things and speaks very good english…! Thank you very much.

I installed a geothermal ground source heat pump when I built my house back in 2002. I live in southern Minnesota around the 44 degree north latitude, so we have cold winters and and hot summers (typical temperature range from -30C to +40C). The system had three horizontal averaging 4 meters underground. It now only has two ground loops due to ground settle from the construction which pinched off one of the loops making it unusable. Installing three ground loops was intentional for redundancy and despite the loss of one of the loops, the system still keeps my house warm and cool throughout the year. If I lost another ground loop, the remaining ground loop would continue to help reduce my energy costs by supplementing the electric heating and cooling portions of the system. The approximate cost of the system was around $11,000 US dollars in 2002. Another advantage the system, a lot less maintenance and costs. Even the air filters are washable and never need replacing. I highly recommend systems like this to everyone in the mid to high latitudes.

I just had Geothermal installed this last may. Works great. Unfortunately no previous energy bills to compare to at my new house. My old house was 1000sqft, + full basement. Bills between electric & natural gas was about $240 every month on budget. $2880 a yr. Current house 1500sq ft+ full basement. ALL ELECTRIC, no gas stove or heat since geothermal. my bills look like this, $60, $63, $83, $85, and one reading which was delayed 3 days and extremely warm month was $128. Which places 5 months of energy around $420... My next 7 bills would have to average $350+ a month to compare to my smaller home with natural gas.

Jeez, these videos are a breath of fresh air that cheer me up.

We had heard of these systems for years. Went from Natural gas heating/water heating with electric cooling to geothermal (heating/cooling/water heating) 3 years ago and love it. We used a new way of installing laterally that also does not tear up the landscaping (turns out the pros have been doing this for years installing conduit under roads). Saved us much money on the install. We increased our PV cells to handle the small additional electric load so we are net zero + pollution free....and it REALLY DOES SAVE MONEY.

I'm confident that another factor preventing more geothermal installation, or any other new technology, is the prevalence of house flipping.

As always, such a clearly told message on a topic that should be common sense for consumers and policymakers alike. Thanks Dave !

We just installed an air source heat pump furnace. It's about to have its first winter. One thing we already have enjoyed, the electrostatic air filter. We run it in fan only mode to clean the wild fire smoke polluted air. Only symptomatic relief to climate change but still, we're grateful. Plus we're no longer burning a thing in our house so there's that too.

I am a refrigerant technician and have built a homemade heatpump on my homebuilt solar catamaran, I use the seawater for heating the evaporator. 👍😅

Reminded me of an installation I did in a home at the end of the 1970s that was very effective, very easy, and very cheap. It was used mainly for cooling in hot months in a New Jersey home. Sunk a 4" diameter pvc tube below ground level to a depth of 6-7 feet with an elbow attached above ground that directed the pipe right through the wall into the rooms just above floor level. A small, noiseless fan was installed - similar to what is used in computers today - and a vent cover was placed on the interior wall opening that had vanes that could swivel to direct the airflow. The underground opening was covered with a fine-grain screen with a 2 - 3" layer of activated charcoal and another filter material was placed on top. What that was exactly I can not recall but it was similar to the fiber-filter material that was used in aquariums at the time - its thickness was ~3". A second filter was placed in the elbow, closer to the intake. I installed 3 tubes for the house which was about 1400 sq ft on the ground level. My set up was manually controlled, each fan having an on/off switch. The cost to run the fans over a year was negligible - less than $1 I think - but it reduced my reliance on air-conditioning units by more than 75%. Well worth the cost and time investment. It was still operating perfectly fine after 10 years. I like the design - easy to install with easy-to-obtain parts - and not connected up to any other system or grid. Flipped on the fan when it was hot; turned it off when not - usually ran for a couple of days at the hottest periods non-stop. The single drawback was the positioning of furniture - blocking the vent reduced efficiency a lot.

I used a water source heat pump for several years for a small rental apartment. It was in eastern North Carolina where the water table is very high. I washed down two wells to 50 or 60 ft depth, and used one to take water from and the other to return the water. It worked well for 4-6 months. Then I got a call from the tenant saying that there was a new pond in their back yard. The return well wouldn't take the water anymore. I swapped the flow direction and the well worked for about the same amount of time. The trick didn't work for long after that. I put in a third well for the discharge and finally used two of the 3 for discharge. It was becoming more of a hobby than an HVAC system, so I replaced it with a conventional gas furnace and electric AC. The heat pump itself was great and there was never a problem with its performance. It is a great system if your water is free and digging wells is cheap.

Thank you so much for your informative videos. You are educating me. I appreciate your objectivity and clarity. I am planning to build a home in the states in northern Michigan in the next few years, and you have helped give me direction with respect to the sustainable nature of the home I will build. Again, thanks, and keep the information flowing.

The most cost effective time to install geothermal for new development is during the subdivision development, when road ways, school yards, park areas can be utilized and the ground is generally all dug up anyway. It tends to support community based heating / cooling systems. This has been done in the US where the developers picked up the install costs and recuperated them by selling the heating back to the home owners over a period of time. I would love to see this concept built into all new developments and the municipalities could play a major role in making this happen.

We installed a geothermal system in our 1800 square foot house in Regina, Saskatchewan, Canada and it operated flawlessly for the 4 years we continues to live there before we moved. If you don't know, this location experiences minus 30 degrees Celsius regularly during the winter. The system handled it easily. Even more efficient cooking in summer where temps reach mid 30s.
