o/t LPG Central Heating
Hi All,
Just wondered if anyone has an LPG central heating boiler.
My solid fuel boiler has sprung a leak, and although it may be weldable I'm looking at all the possibilities in case I have to buy a new one.
I already have an LPG cooker and a coal effect fire so I have the cylinders and instillation into my kitchen.
The figure I need is the litres per month used to run a 30kw (ish) boiler.
A cylinder (47kg) costs me £52.
My solid fuel costs me £120 a month to run, but it's a dirty system.
Many thanks
Paul G

watching with interest as I am an oil user again around 1500 to heat the house anything less expensive would be good.

not too clued up on the cost of lpg but £120 sounds alot on solid fuel also if your thinking about converting your boiler to lpg it might be worth
finding out how much a proper tank is the gas may be cheaper if brought in bulk just a thought

My only gripe with solid fuel is the dust.
I fill it once a day with anthracite grains (black dust  ) and empty the ash pan every third day (grey dust )
Everything out in the sticks is expensive.
O you lucky people with natural gas.
I should point out that £120 p/m is Sept to April. In the summer I heat the water with an immersion.
As I understand it the rules for bulk tanks are a problem.
Must be away from any boundaries, house walls, drains, sewer manhole covers, and must be visible from the road. (fire regs)
This just leaves the middle of my front lawn. No way.
Thanks for the replies

We use LPG biggish boiler now about 17 years old, not sure how expensive it is per month but we have one of the afore mentioned bulk tanks and managed
to get a deal with our supplierat 30 p /litre for next year + tank rental which is about £40 a year.
The big con is you can only use the tank supplied by firm you deal with and they try to charge fees for up lift if you change, we have also negotiated
our way out of that although there is supposed to be some deregulation happening where you should be able to shop around like with an oil tank.
It is a convenient but expensive fuel in our experience -recently installed an immersion heater clock as we reckon it is cheaper to use electric for
water heating than gas.

Is Kerosene completely out of the question?
Thats about 43p-50p a litre I believe at the moment and i'm pretty sure you can get Kerosene condensing boilers.
Obviousley there'd be the tank to hide somewhere but the rules are more flexible than where you can place the LPG tank, and i'd say on
Kerosene you might even get away with it servicing only once a year as it burns pretty clean.

I stand to be corrected, but I've been told that LPG is the most expensve way to heat your house.
I installed LPG for my cooker when we moved in here nearly3 years ago ( don't like electric hobs) - there is no mains gas in the village.
I have an oil boiler - the price of oil has gone up a minimum of £200 per 1000 litres for the 3 times I've filled the tank.
To this end, on Monday I'm having a new multifuel stove with boiler fitted along with a thermal store ( copper cylinder which works in reverse
to normal design ) enabling both heating souces to be linked - when there is insufficient heat from the solid fuel i.e. not lit, the oil boiler will
kick in.
Not a cheap installation, but will definately save me money on the longer term.

What is needed here is knowledge of which energy form is the most cost effective, in ther words, a pound's worth of which produces how much
heat?
I don't have that info, I'm afraid, but last time I looked into it it was mains gas, then oil. Light oil (aka kerosene) is pretty much the
standard.

1m3 nat gas = 10kW
1ltr oil = 10kw
1ltr lpg = 7kw
1kw elec=1kw
get your unit prices and make your comparisons as these figures take into account - roughly the differences in efficiency of the fuels
As for usage of a 30kW boiler - its about 30k/ hour
how long its on depends on the thermal efficiency of your dwelling and what its being used for how warm you want things etc etc etc.
have a google for "degree days"
off top of head lpg is .7kg/l so do your maths

I'm not sure on the calorific value of each but Kerosene was 7p a litre cheeper than Diesel(oil) when I asked a delivery driver the other week
and it burns much cleaner than oil so requires less serviceing

When I said oil, kerosene was what I meant. Very few people use diesel for heating unless they are people who can buy cheap diesel because they have
(for instance) a farm, then buy diesel for the machinery (tax deductible) then use it for house heating (not deductible).

Ahh I never realised that, I just presumed that you didn't pay tax on Diesel for heating whoever you were. But come to think about it the places
i've worked with diesel boilers are usually massive houses and estates that will claim to have a farm somewhere!.
But either way the Keroscene was still 7p a litre cheeper than the Red Diesel which I was suprised about, probably because Diesel is more in demand
now (before its coloured)
