A further question while I am in the (No doubt protracted) planning phase of this idea.
For a warm room that is well insulated and in the interest of the warm room being actually WARM I am thinking on the problem of heating it.
Electric resistance heating is a no no due to running costs. Gas heating on bottled gas might be a potential but in the interest of staying alive, a coaxial flued heater would be the preference so there is no combustion products in what I would hope to be a pretty well sealed room. I am just wondering if the exhaust vent of such a heater would be a concern to imaging due to heat plumes? I may be able to control that if I can manage to work this out so the warm area is in the eastern section of the shed, one of the directions that imaging is limited in any case due to the nearest town being that way.
About the only other way I can think of would be a small reverse cycle air conditioner, split system or otherwise, which might actually be the best option for running costs and would produce cold air outside instead of a potential fumy heat plume, and no issues with combustion gasses in the room with us. It is probably more costly to install though. It would have the benefit of being able to go out and work in the "Shed" in the hotter weather in some comfort.
Am I concerned about something that is nothing to worry about with gas heat plumes from a flue?
