Sorry folks, my wife posted the original question and I gave her trhe details of the 3 boilers on offer but she didn't get them quite right.
They are Ideal Icos 24KW - Worcester Bosch Greenstar24ri high efficiency condensing - Potterton Suprima HE30
Not sure if this makes any difference...
Hi
I have been quoted to have a new boiler installed and he has said that I can either have a Ideal Icos 24kw, a Potterton Suprima 30e or a Worcester Bosch Greensleaves 24 RI High efficiency.
I have been on this computer all afternoon trying to get an idea of which one I should go for...
