Water cylinder in loft??

pat1976

Hi, my 2nd heating related question in a couple of days. I was going to add to the last one but can't find it.

I am having to go with my builders recommended plumber because none of the ones I've contacted have turned up. He gave me a quote based (I thought) on the list of requirements I gave the builder. I asked for a system boiler to be installed with all tanks and cylinder in the loft.

Today he said I couldn't put the cylinder in the loft because it would give very low water pressure, and then he thought about it some more and said he could but it'd be a special (read 'expensive') type of pressurised cylinder.

I thought a system boiler had some sort of pressurised system anyway and so this set up would be ok, but I am not a plumber and obviously got the wrong idea.

This house does not currently have GCH so we are starting from scratch here and can do pretty much anything. Can you help me with this please? I do want a system boiler rather than a combi and am not sure whether this new issue is real or is intended to push me towards a combi, which everyone wants me to have.

Thanks.

Hi: a vented cylinder must be situated below the cold water storage cistern. An unvented cylinder could be located in your loft if you have sufficient mains water pressure to support it and need to consider a suitable route for discharge pipework as well as the additional weight in your loft space. An unvented cylinder will provide you with hot water at mains pressure. A system boiler will only provide a sealed central heating system...it will not, by itself, produce hot water at mains pressure. More here.

I would encourage you to try, one last time, to get an independent RGI in to quote.

Thanks very much for that. I may have to resort to 'rated people', which is a bit worrying!

Noooooo:eek:

Have you tried the CIPHE?

Let us know how you get on.

Stop looking for a plumber, look for a GSR RGI-not the same thing. Only some plumbers are qualified to work on gas appliances.
What are the qualifications of the 'plumber' who did the survey?
Otherwise follow the sound advice above.

Point taken, although for 'plumber' please read 'Gas Safe Registered Central Heating Installer', can non-GSR actually do the work? I had assumed not.

All of the people I tried to get quotes from were from the GSR site. I hadn't tried CIPHE, there are non within my immediate area but I'll give the 2 closest a bell.

Many thanks for the advice, it is appreciated.

Don't touch rated people with a barge pole, to be "rated" all you do is pay a fee and you are on the list whether you have any skill or knowledge of the trade in question.

Biggest mistake I ever made was using them.

One other point here. You say in your original post "not a combi" Why? So long as you only have one bathroom, a properly sized combi would work just fine. It would also save you having to have either an unvented cylinder or thermal store installed just to have hi pressure hot water. If the freezing condensate issue is your problem make sure it is properly planned and run internally then its not a problem!
