I never even knew there was a renewable energy section. I have been involved with geothermal and air to water since they first became introduced in Ireland. I have been making some suggestions to site moderators as plumbing and heating subjects seem to be spread all over boards.ie I wish they could draw all these subjects together in some form.
I have worked on some really expensive projects with geothermal heat pumps combined with air to water and geothermal combined with air recovery.
When considering geothermal or air to water you really have to sit down and do your home work. Most of the providers of these systems are very happy to sell them but when customer's are experiencing problems you will start to see a different side.
The systems are designed to clients requests so you really need to know exactly what your looking for. You should sit down and work out what your hot water requirement should be, what kind of room temperature you require throughout the house, how much are you willing to pay towards electricity, how much of area are you willing to sacrifice for all the units, how well will you be able to control a highly sophisticated control system.
The reason I state this, I have installed many systems correctly in accordance with the clients requests but the clients have discovered some factors later on and became unhappy, should they have notified the company's I had been working for with a full well thought out requirement list, a more suitable system would have been installed.
Most issues I find are to do with over all control of heat and lack of hot water storage.
You have to forget everything you know about traditional oil and gas heating systems. These systems are in a world of there own.
I would prefer ground source geo over air source as I don't believe you get the most out of air source.
These systems cost a lot to install and the whole idea is to reduce bills and recoup the installation cost. If you have an under performing system you wont recoup the costs, may take some time, which defeats the purpose.
