Re: Do you have a geothermal system?

Wed Dec 16, 2015 10:29 am

My brother put in a well based geothermal system. It was very expensive, especially because it replaced baseboard hot water - there were no ducts. The well cost almost $12K, and the system was over $30K.

I think that a mini split system is the way to go. They are much less expensive, and they are nearly as efficient.

My parents-in-law just put a mini-split in and really like it. It runs down to about 5F and then turns on resistant heat, but they have electric baseboards already. The cost was significantly less that adding forced air or anything else because it is all self contained. Honestly I am amazed how quite the system is on both the inside and outside. They are worth looking in to. They also make units that can have a single exterior unit and 2 or 3 inside units for multiple rooms.

There are a lot of options. We'd ideally like to do what your brother did. $30k with a 30% tax credit and up to $12k rebate from MACEC would be doable. Can you share any specifics? Equipment, installer, etc

I like the idea of mini splits too, haven't delved into them deeply yet, but I don't think they qualify for the tax credit, being air sourced. Still, worth a look.

I think that mini splits might qualify. That is a good question. This site might have an answer: http://www.dsireusa.org/

A single zone Fujitsu unit is ~$5K installed. They claim it functions down to -15F, before resistance heat iss used; though it has a heater for the condensation pan to keep it from freezing.

I will have to ask my brother about his system.
