In order to heat a single room in a house, which would be the cheapest
way to do this?
Using oil fired central heating and just heating the one room, or
alternatively not using the central heating and using a portable gas
bottle heater, similar to these...
Thanks for any info!
If you already have an oil fired central heating system, why not use a
kerosene (eg domestic heating oil) powered portable room heater?
B&Q was selling them not so long ago. They may still do so.
IME, they run fine on kerosene without odour, smoke, etc. You do not
need the Tozane stuff but obviously it is probably better if you do..
Much cheaper than bottled gas. Hell of a lot lighter and easier to move
around. I can't even lift a full gas cylinder. Much safer, IMHO - they
may add to a fire but they aren't going to explode/ send a jet of flame
into the ceiling.. Ask a fireman if he would rather going into a burning
room containing a full gas cylinder or a burning room with a few litres
of heating oil..
Depends if you have a two pipe feed from the tank or a single pipe feed.
If a single pipe, cut, inset T piece and short pipe to oil-rated stop
If a twin pipe, then you have to go back to the tank and fit a new
syphon tube with oil-rated stop valve into the tank, totally independent
of the existing pipe-work. A two pipe system relies on the pump on the
burner to draw fuel into and around the system. If you try to tap into
that, the odds are you will let air in and you will need to get someone
in to purge the system...
The heaters have a removable tank that you just refill.
All of the heat energy from the fuel goes into heating the room. Even
with a high efficiency boiler, a central heating system is not going to
achieve that. It heats a single room very quickly - much faster than a
typical single radiator would manage.
A side effect is that all the combustion products are also deposited in
Water. If your house already tends to be damp (eg nappies hanging in
rows everywhere) then you probably don't wan't to add the water -
basically litre for litre the same amount as the fuel used.
Carbon Dioxide/Monoxide. If your room is inadequately ventilated, you
will get headaches and other symptoms of carbon monoxide poisoning -
but, hopefully, the CO detector built in to the heater will trip before
it kills you.
Which is better really depends on your life style:
If you are mostly out and just need to heat a room very quickly when
you come in and just stay there a few hours - then these heaters are
great. Combined with an electric shower and a kettle in the kitchen,
this is probably going to give you the lowest bills.
If you are mostly in and want the room heated most of the time and use
hot water most of the day, then the radiator with a high efficiency
boiler is probably better. But your fuel bills will be more.
