workshop

in THE MAIN WALL
I have a woodshop approx 700 sq ft with a second floor on top. Wondering if the shop could be heated with wall radiators with water heated by a gas unit and the second floor could have pipes in the floor that would heat the second floor. I have about 19" I beam wood trusses between. Trying to have a safe environment with combustion air from outside and away from dust and fumes is my goal. Garage is on a slab which is already there and walls of the shop are already in place. My other conventional option would be to use a heatpump with gas back up. Thanks Allen

    Depending on the heat loss what you describe is ideal.

    Too bad that the space exists and that floor radiant for the downstairs is not an option. My own workshop has a variety of salvaged cast iron which I prefer for it's deep penetrating heat and ease of cleaning. (No fin tube nor convectors except in some older areas before I got smart :)

    The upstairs can benefit from floor radiant but what is key is your ability to insulate below the tubing (sandwich the tubing between the second floor deck and insulation below, preferably with the tubing in an airspace for diffusion of the heat).

    If you are unwilling/unable to insulate the floor above you will underheat the second floor and overheat the first floor with a radiant ceiling.

    My second preference is to use cast iron radiators on both levels. A single set of loops of copper piping around the lower level ceiling can upfeed and downfeed the radiators just fine.

    You can even use PEX for the runouts; aesthetics can be loose, right? I mean, you do not have to wear a jacket and tie in the shop. Flannel shirts rule.

    TRV's on the radiators would be a sweet touch. And a wall-mounted condensing boiler would not take up floor space and give you efficiency and isolated combustion air in the bargain.

    Then there is the option of waste wood boilers....

    Rinnai 1004

    This is an excellent method for heating a garage or shop area. Sealed combustion, direct vent, modualating burner and blower. If it is a wood shop I would recommend primary and secondary dust collection and would blow the unit off/vacuum it periodically depending upon use. Very reliable. Simple install...by a professional. I represent Rinnai, so I am biased in their favor but I have one in my shop and two in my home.
