We have J&S warm air and I've wondered about the cost.

However I thought it was quieter and less complex than a water system which
has pumps, pipes, lots of water. Also it gets warm quickly but hasn't got
the very hot radiators to put your backside on.
Overall I can't justify changing it as its not on in the day and is only
needed for 6 months of the year.

We use an immersion heater for hot water as the pipe runs would be too long
from the boiler.

Hi I live in a 1991 built semi with 3 bedrooms and the heating system is
gas fired warm air by Johnson and Starley. It is again starting to get
noisy, I must by a can of WD40. I already had the fan replaced a few years
ago.

After discussing(arguing?) it with my wife she has said that she never
liked the heating anyway and wants to replace it with radiators. I was
wondering if there was any sites that compare the merits and costs of
running the 2 systems and also if anyone knows if radiators would be
cheaper to run than the present warm air system? I spend about £360 a year
at present on gas for the heating and hot water and cooking and wonder if
the running costs of radiators would be significantly cheaper or dearer. I
was wondering if there would also be a saving on my electricity as I
assume running a central heating pump would consume less electricity than
a dirty great big fan.

Also because of the constant hot water( there is no automatic on off
switch for the hot water other than manually turning the thermostat down)
I have a power shower. Would I still be able to use this if I got a new
more efficient hot water system or would I need a new shower. I used to
have radiators in another house and when they first came on they used all
the hot water until it heated up again as I found out when I started to
run a bath just as the timer switched the radiators on, but that was a
coal fired system.

Another cost saving would be that I would no longer need a maintenance
contract with Scottish gas as there is less to go wrong with a radiator
system than a warm air system.

I have a garage attached to the side of the house so I would hope that the
boiler could be situated there.
So I am looking for some advice and suggestions from people who have
changed from hot air to radiators or anyone who wants to chip in.

Thanks Ronald
