Paraffin heaters ?

A local builders providers has a special offer on paraffin heaters , does anyone have any experience of these heaters for heating sheds ? Does burning paraffin give off water in the same way as gas does ?

give us a clue simlar to greenhouse heaters or one of these http://www.google.co.uk/products/cat...0CF8Q8gIwAwthe greenhouse heaters stink the latter doesnt and doesnt cause condensation but use a lot of fuel and a bit noisy

Any heater powered by liquid or gas fuel burning directly in the atmosphere will cause massive condensation.

Its the same type as the one on the right in the top picture on the link below.

Definitely. I believe they say it's a litre of water out for every litre of fuel used, is it not?

That's the reason I've always stuck with an electric heater upto just. They ain't the cheapest to run, but at least they're neutral on the moisture front. No room for a log/coal burner either, (when you also allow for the dead usage zone required around them), so unless I ever figure out a decent way of venting a paraffin heater outside without losing most of the heat from it, electric I'm stuck with.

And these days paraffin aint cheap!!!

I used to have a paraffin heater and worked OK. Never had a problem with condensation in a wood shed but also had plenty of ventilation. In the garage never got it hot enough to cause condensation ;-) Now I've got a large propane bottle and use a small blown heater to get the temp up and then change over to a small gas radiant heater near me to stay warm. Outside I use an electric infrared patio heater.

Gas heaters are just as bad on the moisture front. Whilst ever the temperature is kept raised, the moisture will stay in the air, (upto a point), but let the temperature drop, and that moisture will condense wherever it can.

Yup , condense on my lathe , mill and pillar drill mainly .

Aye, that's the worst problem with large masses of metal. That's why I stick with electric options, even though it is just about the most expensive option to run. Solid fuel or electricity are safe heating means, moisture wise. Everything else will eventually give grief around machinery unless there's constant ventilation and airflow, but then you're in a swings and roundabouts situation because you're constantly replacing the heat you're removing/losing.
