I've just had a 6' x 6' shed erected in the garden to house a few
stationary engines which I want to keep above freezing in the winter. I
do have an electrical supply nearby. What are folks thoughts on the most
efficient form of heating that will keep the shed just above freezing
point?.

Electrical Tubular heater 5' 200w (has the advantage of having a frostat
onboard)

Old fashioned paraffin heater (I would have to light it if the
temperature was liable to drop below freezing)

Any thoughts, comments or suggestions welcome



Dessicant based dehumidifier - mine can run at 300W or 600W and it's a
double win - bit of warmth and the air is dried out.

If you have a fairly airtight shed it seems to work very well. My shed
has 50mm celotex on the floor and about 60% of the walls (rest and roof
is a later tuit) and 600W can bring the temperature up a good 10-15
degrees - but it doesn't need to run that hard to keep the humidity
below about 40-45%.
