Workshop/Garage Insulation/Space Heating

[Howard LewisParticipant @howardlewis46836]

If anyone is interested, my thermostat is set at about 18 C.

Being well insulated, the 2 Kw fan heater heater, once the shop is up to temperature, cuts in infrequently. aided by by heat from machinery and myself.

Any combustion heater needs to have the products of combustion vented outside (And the system to be well sealed, to avoid you being poisoned by carbon monoxide, let alone any water vapour escaping into the working area &nbsp

By all means insulate, but do not seal completely. Leave the bottom of the door unsealed so that the moisture from the wet bikes can escape.

Years ago, I sealed the bottom of the garage door, and the car rusted like crazy!.

Also, you need some fresh air to breathe!.

My small shop has two small fixed vents at floor level, and a fan, at high level, that can be switched on when needed, exhausting into an external weatherproof hood.

Howard, John,

Another case of an ancient thread re-ignited on a specific topic…. when a new thread would have been far more sensible. This possibly useful question will likely never be found by a simple search, in the future.

My workshop, a double garage, has 4” celotex in the roff and on all the walls, under the 1/2 in stirling board. The floor has those foam workshop tiles on it an the doors are fully draught proofed under the rapidly removable celotex sheets. Primary heating is 2 greenhouse heaters fixed to the lathe and mill. There is a thermostatic plug on an oil filled heater set at 15 degC but it rarely needs to work. The celotex was cheap…. Factory seconds, and the overall running costs are very low.

I wonder how many of the workshops that suffer with condensation and rust issues have much in them that acts as a buffer for humidity. My workshop is single brick but lined with 70mm celotex and then internally skinned with 12mm MDF. It also contains a fair amount of wooden sheet material. All this acts as a buffer to absorb moisture out of the atmosphere. I suffer from very little in the way of rust.
