If you are talking about open flame LPG fires then forget it the condensation resulting from the amount of water they throw out is horrendous.

If on the other hand you are considering an LPG boiler then very carefully weigh up the costs. To start with the boiler itself will probably be dearer than an equivalent natural gas one because it is a smaller market. As for how practical it is to run it off cylinders I do not know even if it is cost effective do you really want to be out there in -5°C changing over cylinders. I think most people running off LPG tend to have a large gas tank in the garden, so do you have a suitable garden and it will still probably require some digging to run the gas feed into the house. When you weigh up all these costs it may not be cheaper than running a gas supply in from the street assuming there is gas there.

Friends this summer have had oil CH heating system installed with a bulk
tank in the garden. No mains gas available and the previous system was
20year old storage heaters. The new radiators are around the third of
the size of the old storage heaters and have freed up a lot of space in
rooms.

Various other option were considered
LPG supplied from bottles
LPG supplied from a bulk tank

For LPG from bottles you would need 47kg capacity bottles for domestic 3
bed house heating and typically around 20+ refills during the winter or
cold months. Cylinders containing the much gas are not something you
are likely to put in the back seat of your car to take down for a
refill. It's something that would be delivered and let someone else do
the heavy man-handling. You would need to have two or three cylinders
that you could change over to cover, say, the Xmas holiday period when
deliveries may not be possible.

Potential running costs:
Propane in 47kg bottles = £1250/year (possible needing 22 refills)
LPG from a bulk tank = £756/year
Heating oil from a bulk tank = approx £730 (possibly less at current
oil prices).
All solutions also give hot water, not requiring electric heating.

With potential running costs of £500 more per year for bottled gas this
solution was rejected.

The quotes for the boilers/radiators/bulk tanks etc were fairly
comparable with the 47kg bottle solution being £2K cheaper, I believe
the regulations for installing a bulk LPG tank may be more onerous than
for a oil tank.
