Thanks @DigiGal. Its a slow process doing this in my spare time nights and weekends but I am psyched to be able to make things out there. Trek and non-trek.
I put in floor heating into the main house. I love it in the bathrooms and bedrooms. Its a leave it on and keep it heated kinda system because of how long it takes the thermal mass to come to temperature especially if you are going to do so efficiently.
We put Fujitsu heat pumps in at the house last summer for the air conditioning. They are so efficient that my electric bill went down during the summer because they used less electricity than the ceiling fans. I was shocked. I am even toying with the idea of these new heat pump water heaters for the house but thats another topic lolf.
In any case I think and hope it gives efficient heat for the shop and as a bonus air conditioning on hot summer days.
