the Shelter is going to be regulated to shop duties this year. Not putting that much effort into heating the house. It works efficient but is too labor intensive. I’m looking at a couple different boilers right now but, I have zero experience with them. How big of a pump for a 50-100 foot run for heat exchanged, water to water heater, and a air handler for the garage? How deep should I figure on digging in the lines? Is the wrap insulation sufficient? I’ve seen so much both ways. 1600 sq ft living space with unfinished basement. I am looking at two brands. The EZ-Boiler larger unit since I eventually would like to heat with floor heat in the new shop is my first choice pending the trip to inspect one soon. Looks like a solid unit. Of course I’m also looking at a Central Boiler unit too. I want to look at one up close since I have had the fun of a cheaper unit with this shelter. Any and all feedback of pitfalls to avoid and suggestions would be wonderful.
