LPG Stoves

No, we're not traitors to the cause as we have a woodstove already but we also have a largish extension (sunroom) that sometimes needs heating in the winter. The woodstove heat is usually enough to keep the sunroom warm until it gets to minus-numbers outdoors when some supplementary heating would seem to be of benefit.

We're undecided as to flued or unflued but suspect, for simplicity, that the unflued version will win that argument but other than browsing a gazillion available versions I have yet to meet or discuss these devices with anyone that has PRACTICAL experience of them.

So.... anyone got one? Pro's and con's

I would always go for an appliance that is room sealed drawing air in and venting waste products out to the outside air. A thing that sticks in my mind was back in the 60's when I was with the gas board. The natural gas conversion was well underway and part of the programme was ensuring enough air got into the room through vents. These were a bit self-defeating in heat loss terms with bloody drafts blowing through but the new gas needed more air to burn clean. We had a terrible case where a chap had unwittingly blocked all drafts in his bathroom to stop the cold. Unfortunately, he had one of those old fashioned water heaters over the bath, we used to call them geezers, and these appliances used a fair bit of fuel running a bath. Regrettably, his young daughter died in the bath as a result of monoxide poisoning. It was a terrible thing to happen and I have never forgotten her name, it sticks with me. So I may be biased towards the flued type of appliance.

I am sure you have thought of that issue already.

Modern gas heaters (well, some) are fitted with catalytic converters that ensure 100% combustion and no CO - the ones I'm looking at also monitor oxygen levels and shut off if they drop 1.5%. Of course the mandatory 100cm^2 vent has to be properly fitted but that's just common sense.

As for condensation...... funnily enough that's not mentioned in all the bumpf and is usually an issue I know so maybe a flued one is better?

Trying to understand how it can give off a gallon of water, if you only have a gallon of fuel in the first place?

Old tech but you can't go wrong with a Baxi Brasilia assuming you just need a couple of kW output.

Flueless fires are safe if installed exactly to regs but they are a decorative fire and the heat they give 1% of the year doesn't make up for the drafts the rest!

We have a balanced flue gas fire that exits outside, and draws in air that way too. It even has a remote control.
Best thing we did, buying it.

It says you get water (I never questioned that) but what I don't understand is how you get 1 gallon of water if you only had 1 gallon of fuel
