for months my hot water only works when it feels like it now it's none existent and my central heating is not working now either. i got some one out to have a look at it and he told me there is three things wrong with it .firstly i have a leak at the diaphram!! the pressure isn't working right and also some other thing i cant quite remember but he said it could end up being one of two circuit boards. he said i would be patching up an old boiler basicaly. the make is biasi prisma 24se model type c year 1997 ( is this classed as an old boiler in boiler land??? ) i have been looking at boilers to buy over the net but am at a loss. is there a big difference in combi boilers and condensing boilers? do i have to stick to a certain type ? also what kw should i be aiming for ? i'm really out of my depth here as you can probably tell don't want to spend hundreds on a boiler then find out it's no good. also how much should it roughly be for it to get fitted . if you have had the patience to sit and read this then i thank you and say sorry for my complete ignorance in this field thanks anna
