Heating 8x14 room

[notrightnow]

My plans are to build a 30x40 shop this spring. I will be heating the shop (maybe wood) only when I need it.

I will be building another room within that will be 2x6 construction and fully insulated. I would like to keep this room heated at all times, just warm enough to keep tools/paint etc... warm.

I was thinking of an electric in wall heater. My quesition is about a Fan heater versus Convection heater. Would a convection heater heat the room as well has a Forced fan heater. Would it cost less to heat due to lack of fan?

Notright now I would love to help but dont know where you live so I dont know what kind of conditions you are facing . I live in Ky. I kep my 450 Sq' garage reasonably warm with a floor standing 1500 watt convection heater so I would say that small of an area well insulated you would be fine with a convection type heater.

I'm in Canada. We have had winter temps this year to -40 F with the winds.

I have a small 600/1200 watt heater that I've used, in a pinch, to heat a 12' van body that I used to use as a workshop years ago. No insulation but it kept the inside well over 60 degrees in Wisconsin winters.

Q-Mark makes a variety of recessed fan-forced heaters in differing voltages and outputs. 1 KW would probably be more than enough. They are good units. Make certain to order the back box.

Fan-forced means a faster warm up of the space, but you will find a lot of dust and dirt buildup if used in a work room. There is no standard filter for these units. I have seen some cobbled up filters but this would likely void the UL Listing.

If work room is to be constantly heated at a fixed temperature, I would look for Chromalox electric baseboard heat, placed along the outside wall. You would have less noise, less air drafts and a more consistent temperature (less cycling of the unit). This will still require vacuuming occasionally to remove dust, and are a little bit more involved than a cabinet heater to install. Also more expensive than a cabinet heater, but come in various lengths and wattages. Spec a heavy duty cover if likely to get kicked around.

Above manufacturers are listed to establish a level of quality. Tons of other suppliers out there to choose from.

Decide what voltage you are going to use. Don't over specify heat output. Resistance heat at this level is essentially controlled on an "on-off" basis. Better to be a bit under sized than over sized. Also this (electric resistance) is the most expensive way to heat for most consumers. Almost all of these have contactors or thermostats that produce a spark. Be extremely cautious with what you are doing. I always recommend a dedicated flammables container for paints and solvents.

Good luck.
