for a large house with lots of rads and two bathrooms, you may want to consider splitting it into two zones by using two smaller boilers.

CN said i've got to play nice or he might be nasty to me again lol, if the house is over 150m2 then it should be split into two or more zones anyway (see building regs), plus if the house has lots of hot water requirements (mulitiple bathrooms, en-suites, showers etc) then a combi isn't suitable/best option anyway, in that instant i would either go with a conventional system cylinder & roof tank (oops sorry CN cistern), or a mains pressure unvented cylinder with possibly a secondary hot water loop, but now you are getting into a lot more work & money, i wouldn't go down the two boiler option i think it is totally un necessary & at the end of the day any combi is only as good as the incoming mains supply anyway, in regard to someone else that posted on here, the op already has a combi so the pipework is already under pressure so i don't think leaking pipes would be a prob.

Hi, Linda: the OH fits usually Vaillant and Viessmann products but offers Remeha as a budget option....if you are in the south of England prices for Remeha boilers are available here. Add to the cost of the install, an annual service to maintain the warranty.

A RGI, on site, should be able to advise as to what might be the most cost effective option to meet your specification.

Let us know how you get on.

Annual service - Is anything really done?

A good CO monitor is a better investment

Are you crackers?

So what are you going to say when the boiler breaks down and you call the manufacturer and they say "show us the evidence you have looked after the boiler?" ???
There you go Mr Engineer, I decided it was more cost efficient to spend £15 on a CO monitor!?!?
CO monitors dont check boiler seals, stop possible expensive damage occurring from minor problems, fill in your service interval paperwork and give out basic advice regarding the maintenance of your boiler!
You're a Fool!
