You're right none of the radiator pipework has been prssure tested. I have no idea why, as if it was me i'd definitely be testing it prior to an expensive floor being laid. Anyway I have disclaimed against any pipework leaks on the existing work. It's not a great way to go about doing a...

Thanks for all the replies. Yes Agile the radiator output is too low, and i've advised the customer of this. However there has been £20000 spent on oak flooring which is now all fitted. So it's a case of tough luck if this turns out to be the case. I'm going to fit 2 30kw viessmann system...

Not sure what the exterior dimensions are. All the radiators have been hung, due to a very expensive oak floor being fitted. I feel they are undersized, but there is nothing that can be done now. This is why I haven't been able to do a proper heat loss calc. I've just totalled all the rads to...

It's on LPG with two buried bulk cylinders. It is a very big house, 8 bedrooms, 30 radiators. It's an old restored hall. Thanks for the ideas.

Just wanting some ideas from any heating installers. I've been to quote for a very big house. The heating load is 57kw. I was thinking the best way to achieve this would be to install 2 30kw system boilers side by side, with an unvented cylinder. The heating system is in 2 zones, so...

Just been to take a look at a job which requires 57kw. It's a big house, and all the radiators have been hung (not necessarily correctly sized), but no boiler fitted yet. I'm proposing to fit a system boiler with an unvented cylinder. The radiators and cylinder will total 57kw. Just wanting a...

Get the plumber to do it :D

If the new gas pipe needs to be run behind kitchen cupboards, why not remove the plinth, and run the gas pipe at low level, or even on the outside of the house. 3m of pipe won't take long.

Why would you want a boiler in your living room? Personally I don't want to listen to a boiler firing up while i'm watching TV.

Nobody is going to say you haven't got a G rated boiler. However, there are spot checks being made pre and post installation. So I guess you can take a risk if you want to.

Scrap it, that boiler is band G.

You need to get the installer to measure the flow rate you have, and size the boiler accordingly. Either model will be more than enough for your heating requirements. Combis are sized for hot water demand. The vitodens is a very good product. The 100 is a new product, and any of the earlier...

A baxi solo 2 isn't band G, and therefore won't qualify for the scrappage scheme.

Yes I was thinking it was a bit of water into the PCB......another trip to parts centre then!

It fires on hot water demand though.

Hi, Fitted a diverter valve on a 105e today. After fitting I got a 'pump fault low pressure' flashing neon. The pump runs, and there is enough pressure, so i'm thinking it may be a PCB fault. Anyone else had this problem? Thanks.

The tap may well be faulty, and you will have to remove the bath if it needs a new one. I can't see how the bath would break if it is removed carefully. I'm guessing your plumber doesn't fancy taking the bath out, which is understandable.

A good idea would be to contact some local heating engineers, and ask them if you can work for them 1 or 2 days a week for free for a year or so. You will then be able to get some good gas and plumbing experience. There's no quick way, just takes some time and effort, and of course money to...

Why not just pay a local plumber to check it out, or re-do the joint if you're that worried. Shouldn't cost more than about £40.

I'm on the notts/yorkshire border. The £49.50 comment was obviously a joke!!!!!
