Radiant heat slab in a wood shop
I have an 1800 sf woodworking shop built on a 6″ concrete slab, insulated underneath and around the perimeter with 2″ of foam. The building is well-insulated, well sealed and has few windows.
I’ve been using a Takagi Jr. to heat it for the past couple of years but it’s been no end of headaches. I only have propane and electricity to work with, by the way.
I’d like to figure out a better way to heat the water, probably a direct vent system so that the wood dust doesn’t create problems with the burner (just one part of the TK jr. issues). It seems that my options are either a better version of the current on-demand hot water heater/boiler, or a tank-style water heater.
Are there other options I should consider, and are either of the above ideas impractical?
Thank you in advance for your input.
