Tarm B55 here and house around 1600sq feet along with a non insulated 24x24 garage with open celling to rafters I would like to heat this winter. located in CT house is baseboard with some under floor in the living room, most of the walls are not insulated as It was built in 59 and I guess it was an option but has new windows. garage will be heated directly from the boiler with 2 45kBTU modie heaters and also set up as the emergency head dump zone if my boiler gets too hot. only looking to keep the garage at like 40/50 unless I'm actually working in there I have seen some of the DIY hot storage tanks from wood and plastic liners which for me seems the best bet as moving large heavy tanks into my basement isn't really possible. what can you guys recommend for me, 400/500 plenty or 1,000 really needed? I've seen a lot of different set ups.
