So you’re thinking about a do-it-yourself geoexchange / geothermal project…
1-Kudos to you for thinking outside the box, saving on fuel, and “going green” with your project!
2-A DIY system is a bold and ambitious idea BUT it is STRONGLY RECOMMENDED to have an expert install a GSHP (ground source heat pump) system – with about $10,000 of equipment alone invested in such a system, it is worth having your system designed by someone with years of experience.
Part of the reason for this website is because now with geothermal/geoexchange becoming more popular, there are a lot of ‘geothermal installers’ out there who don’t have much experience in the field and they won’t necessarily be able to do a good job.
You would do well to consult with a professional – with a track record – and check their references thoroughly, as the
success of your system is at stake.
The prospects of a DIY radiant floor system working satisfactorily are not good, but as for the geoexchange component (at the risk of seeming pessimistic), the prospects are bleak for a first-attempt to work at all.
