BS 2869 C2 - for flued appliances (central heating boilers)

Class C1 is much lower sulphur content and very much higher Smoke Point. It is probably lower density as well, but the spec doesn't call for that, relying on Smoke Point to achieve that.

Years ago our local distributor got a very large fine for selling C2 as C1.

If I were using this in an unoccupied greenhouse I would use C2. The water and carbon dioxide would be beneficial to plants and they probably would not be unduly impacted by the other minor products of combustion

If I were using this in an enclosed space to which employees or the general public had access I wouldn't. It just takes one employee with a headache or customer with a grievance to complain to an outside body and you risk a world of pain.

BUT I wouldn't use a flueless appliance in an enclosed space occupied by people in the first place. The condensation alone would put me off, but the high CO2 and risk of other products of combustion would be unacceptable to me.

I shudder at the recollection of the fashion for LPG fired 'cabinet heaters' a while back.

Isn't modern C2 ultra low sulphur anyway?
The rooms are ultra draughty anyway. Yes more insulation the way to go but the landlord is a nightmare.
And people managed for many years with portable calor fires.
I am very fume sensitive. I couldn't cope with a Calor heater but these heaters are fine on the parrafin supplied. I will try and source an IBC of C1.

Air source heat pumps are about the cheapest form of using electricity to heat a building.

I would consult one of the environmental bodies and see if you can get a grant for being more green?

First thing I tried! Don't be silly we not on benefits!

Also noted the tests on both fuels are carried out on wick burners. These things don't have wicks!

I also looked into putting in a conventional oil boiler and radiators .Plumbers told me the run was too long. I don't see that. 30m length of offices down one side of warehouse split into 3 and 4m wide. Easy job I would have thought. Boiler down far end against an outside wall.
Plenty of resturants etc have longer runs than that on normal pipework.

Jet Fuel has a Smoke Point Specification.

Jet Engines don't have wicks either.

Personally I would investigate Heat Pumps further.

Burning Hydrocarbon fuels will produce water vapour. Burning it in flueless burners will put the water vapour into the workshop atmosphere.

Running the flueless heaters in conjunction with dehumidifiers (these are essentially air-source heat pumps that recover the latent heat of vapourization from the water vapour produced by the flueless heaters) is a pretty good way of getting cheap heating without too much of a condensation problem.

The dehumidifiers are best run 24/7 and the flueless heaters are best run only when there are folk about.
