Got you! I definitely need the certificate and I'd rather pay a little bit extra to obtain a few more certificates as we go along, than be left "hanging" for months until the final light bulb gets fitted.

Could you please advise me on the process of obtaining a certificate for building control purposes. I am getting quotes to have new electricity supply and fuseboards installed into the utility room at a new build. I have not yet bought all the light fittings, sockets, switches etc. Kitchen has...

I have had a pressurised hot water cylinder for many years, and when hot, the pressure on the hot taps was crazy. You could be in the shower for quite a long time before hot and cold pressures equalised. I am now at a new house looking to install at a new hot water cylinder system, and looking...

No, brand new system, so we can do what we like. Will ask if the Worcester Regular Boiler can automatically put out top heat if there is a large difference between thermostat and ambient, or if hot water is needed. Or maybe it does it on the difference in temperature between flow and return...

I have a feeling the "cool radiator" idea maybe suspect. Anyway in my system I want *at least* 65C water, as I already have experienced contamination with lower temps and a megaflo, so I will ask the installer to set flow temps to something suitable, eg 65C-70C or more. Or maybe there is a way...

I am being quoted by a few plumbers to install this system boiler, Worcester Bosch 8000 35kW. I have added up all the radiators, total 23, and they work out to about 31kW, so the 35kW seems to be OK. There is also a lot of pipes in the house, large runs are 28mm, small runs 22mm and 15mm to...

I will make sure I ask then if they have a "back" and a "front" before I buy.

Ahh, I did not think you could ever do that, mounting brackets, welds, paintwork etc Thanks!

Sorry I do not understand this. All vertical rads I have looked at have "input" at bottom right and "output" at bottom left. One only has interchangeable input and output, both at bottom and top. So if my flow pipe happens to be on the left I will not be able to use most of these vertical...

Not a plumber, and am learning as I go, but if the flow is boiling hot and the return is just warm, and no radiators are even hot, then something is using up all that heat, where is it going? The hot water cylinder perhaps? Or, what if the pump is real slow and the flow does not reach remote...

Thanks for the quick reply. Since I posted my message I checked the links below and now I see quite a few issues with flow in these radiators and heat reaching the top. So it seems we definitely want one that has the block fitted already, and we should also obey the indicated direction of...

Hi guys, quick question, I am thinking of buying vertical column radiators, and it seems some require input on the left and output on the right, whereas some others it shows you can plumb them in almost any possible way (input at the bottom left or right or at the top left or right ). They all...

OK, my latest calculation shows 28kW (heatadviser) without losses on pipes and without hot water cylinder. I suppose the 35kW would be OK. One more question if I may, is it possible that flow does not reach some remote radiators because it loses pressure at the previous ones? Or is it a case of...

When selecting a gas boiler the gas people (who have been to quote) calculate how many radiators, how many watts each, and the hot water cylinder, and they come up with a required boiler wattage. They have, all, so far, settled on the Bosch 35kW boiler. I did some counting and I have 24...

Trying to find a reliable radiator sizing calculator, many of them seem to be copies of each other, and some produce wide ranging values, do you know of a good one ?

That is exactly what I was looking for, simple and easy to just press the button and go take a shower.

Could you please suggest a timed switch for the towel rails in the bathrooms, and would like them to be in the region of hours, so an ideal "switch" might be just two buttons, one does 1 hour and the other does 2 hours. Those I have found go up to 12 minutes I think which is not enough.

I have a whole lot of these, Marmox boards they are called. I originally got them to tile over shower areas upstairs.

Exactly right! After every stage there is another to fix the problems created by the previous guys. Always the same story.

I have 37.5mm insulated plasterboard I could use, but I am worried about the fixing, it is just foam (rigid but still) and paper at the back. I want something sturdier.
