your best bet is to get a plumber in to proper size up the required boiler

Whilst number of radiators is a factor it is a faxctor in a list of many others

Get a few quotes and go from there

Most people do prefer and recommend Valliant and Worcester Bosch though but sizing is needed from your plumber

Hi Seamansam,

Everyone will give you their own recommendation on boilers. Personally I've fitted the Broag Remaha Avanta Plus and can only sing their praises. They are made by the same company that make Vaillant boilers, just with a different brand name. Excellent and covered by a full 5 year warranty.

Combi-boilers should not be sized on heating requirement, they should be sized based on your hot water requirements. How big is your house? How many showers/baths/taps/draw offs would be used at any one time? If you're likely to use 2 at once frequently a combi-boiler may not be the best option.

Steer clear of the cheaper 24 and 28KW boilers is my advice. The 35-40KW models are so worth the extra money, especially when you want to run baths.

Also, make sure the installer checks your mains water pressure, you need a certain amount to install and run a combi-boiler effectively (how much depends on the boiler).

Magnaclean is a great idea, as is running all the hidden pipework in plastic to keep the costs down. This should significantly drop the labour cost.

As for radiators, go for good radiators with a 10 year warranty - I frequently go to new-build houses to replace cheap rubbish radiators.

In short, spend good cash on a decent power boiler and good radiators! If you have a family and 2 or more bathrooms then in all likelihood you'll be disappointed with a combi-boiler.
