Any particular reason you want a fan? I find plenty of airflow from the gaps around and below the garage door. Or are you talking about a fan heater?

I have fans running all the time when the poly/conservatory doors are shut down. It is as important as heating for the health of plants and dramatically reduces the risk of botrytis (damping off fungus).

I have one running now in the covered area which I have draught proofed two weeks ago.
Best regards

I recently bought one of these. Currently £25. Usually £39.

http://www.greenhousepeople.co.uk/searc ... =1&x=0&y=0

It can be used as a fan and also has various thermostatically controlled heat settings. Not used it through a winter yet but it's in use in an area of my garage cordoned off with curtains of bubble wrap. I don't expect it to be brilliant for the money. Got a different one for the greenhouse:

I'll have 4 extractor fans running in the greenhouse when it's finished, they'll suck air down from the eaves and channel it through the heatsink below the floor then back up again.

This will help distribute the heat evenly, provide airflow and bank whatever daytime heat accumulates to reuse at night.

That's the plan anyway.

Nobody keeps cars in them anymore Jim. Just plants in need of over wintering. Low light levels can be a problem.

Don't those heaters have a fan only setting as opposed to fan + heat?

Yep they do and the fan can be turned up to stay on constantly while the heat comes on as required. Can't vouch for their reliability or fuel economy just yet though.

That's right, our houses are too wee and as result we also have to use our garages as storerooms for various things. Mind you, most modern garages are also on the wee side and you would struggle to put a normal size car in them and be able to open the doors without any problems.

The ideal is a fan heater with a setting where the fan runs constantly but the heater on thermostat. Never seen that set up, so had a separate fan blowing through the heater last winter. It keeps the thermostat switching very precise as air is constantly blown over it.
