Hi I have Jemplair hot air central heating that is coming up for 15 years
old. I also have a maintenance contract with Scottish Gas. I have had a
letter from them saying that as the heating is reaching the end of it's life
I might consider replacing it. I quite like the hot air heating but my wife
would prefer radiators. Would replacing the hot air system with radaitors
lead to a significant reduction/increase in my gas/electric costs. At the
moment we leave the heating on all day and are paying £23 month direct debit
for gas and £25 month for electric, though I expect that to go up shortly.

What would be the savings in electricity using a pump instead of a fan and
heating water instead of air?
And should I just wait until Scottish Gas decide that it is no longer
economical to service my heating as I am in no hurry to change or replace
it?(no money)

All comments and advice welcome
Thanks Ron
