I own a flat and rent individual rooms to people. These rooms currently
have individual electric heaters and I am considering having central
Does anyone know the cost comparison between electric and gas central
heating? This site suggests that in fuel terms gas heating is half the
cost of electric but that when all factors are considered electric
heating is cheaper.
Electric heaters also seem to me be more flexible as timers can be set
for the heaters as the occupiers wish.
Would welcome any comments.
Well, it's written by a manufacturer of electric heaters.
That's not to say I'd dismiss it, but you must read it with
that bias in mind. There's not enough info in the article,
but it could well be comparing a brand new electrical
installation with a 30 year old gas boiler -- you just can't
You can do the same with a zoned heating system, but it will
be more expensive. On the other hand, you can't really just
heat parts of a house very successfully, as the internal
parts won't be well insulated from each other, and if you
have some areas which are significantly colder than others,
you'll quite likely start getting condensation/damp problems.
If you broke down your current costs, people might be
better able to comment on comparisons, such as:
Number of kWh's per year, and how much you pay per kWh.
Cost of maintenance and depreciation/replacement of electric
heaters and related controls/wiring.
Are the existing heaters on timers/thermostats/storage?
Is each tennent separately metered, or how do you split
the heating bill?

Generally speaking electricity is more expensive than gas, electric heating
is cheaper to install than GCH, and GCH costs less to run in the long term
once the initial higher cost of installing a GCH system has been recouped by
lower running costs. As you say, electric heaters can be controlled
individually by timers whereas the only way of controlling the individual
radiators for GCH is by thermostatic radiator valves. Get some estimates for
installing a GCH system then calculate how long it might take to break even
in comparison with running individual electric heaters, based on the claim
that gas heating costs half of electric heating.
