So I am in the process of pickig out a hot tub for our deck and have a few questions. I am considering hooking into myTarm system. How is this best comleted. One issue is that my Tarm is in a boiler room behind my garage, piped underground to my house but the hot tub would be installed on the far side of the house. Where do i hook up for the hot tub?? At the point where the piping from the boiler enters the house or where i tie into my home system? How much more wood would I be usng and how do I figure out what size heat exchanger should i look for? I plan on buying a hot tub that is well insulated and would be installed on a raised deck off the front of the house. I plan on also insulating the underneath/sides of the deck to help with wind/snow etc... Sorry for so many questions but I want to plan for it now so I can figure out the best course to follow. Thanks
