can you not get bottled gas or oil?

Back in the day IIRC the cost for energy used to be (cheapest first):

Mains gas.

Mains electric.

Bulk gas or oil or solid fuel.

Bottled gas.

Wood is a bit of a funny one because it used to be dirt cheap but with
all the trendy wood burners it is now very expensive in most areas.

If the list above is reasonably accurate then electric heating (of
almost any sort) would be cheaper than bottled gas.

I think you have oil in the wrong place

no-one would ever install an oil CH system if electric were cheaper

what would be the point?

tim

Good point; costs vary a lot over the decades.

From Which? - note the use of "gas even for oil."

OUCH! Interesting that oil is so much cheaper than gas at the moment. It
throws your point back, I suppose. Why would anyone install LPG when oil
is nearly half the price?

I wonder if oil and LPG prices don't track each other?

Revised answer - install an oil boiler and get payback in just a few years?

Gurgle. This suggest that (if the figures are correct) that is currently
cheaper to heat your home and hot water with oil than with mains gas.
Which then prompts the question "why would anyone buy a gas boiler when
oil is cheaper?". Yes, convenience and less price volatility, and no
issues over storage, but still.....

Cheers

Oil cost great deal more a few years ago. And oil boilers cost about
twice as much as mains gas boiler.

And might the tank need replacing?
