CH replacement strategies
OK, this is probably not DIY, but bear with me..
My aging Baxi Bermuda system is on its last legs, and I want/need to replace it with a combi system so that I can reclaim the storage & header tank space. The existing radiator circuit is reasonably sound, although the majority of rads are at least 20 years old. Question: is there any mileage in getting someone to install a new boiler (planned in the kitchen), picking up feeds to the existing system? The Baxi is in the lounge, and as it is a converted bungalow, the pipework is fairly "organic". Otherwise, should I strip out the existing myself (and risk missing something obvious), and go for a clean new install, or should I allow the installers to do that, possibly reusing any appropriate pipe runs to save work? I think I know the answer, but I'd like to know from anyone else who has had similar a dilemma. Cheers, Bramblestick |

We had a Baxi Bermuda in the lounge, a hot-water cylinder in the airing cupboard and just a single tank in the loft. I discovered through this group that this is what's called a "primatic" system and not suitable for putting chemicals such as corrosion inhibitor into, so all our thirty-five or so year-old rads were full of corrosion silt and crud. I suppose we could have had it powerflushed but thought that the rads probably wouldn't have stood up to the increased pressure of the new closed system, so we opted for a complete brand new installation, rads, pipes and all. |

A combi system is higher pressure. I'm not saying there will be a problem but I wouldn't be suprised if it leaked as all the rest is 20 years old! You might consider a thermal store - I think they are well worth a look for a replacement installation. http://www.plumbingpages.com/feature...Thermstore.cfm They seem to promise the best of both worlds! -- Bob Mannix (anti-spam is as easy as 1-2-3 - not) |
