I presume it not VIR rubber then? 1958 is early for PVC I would have thought.....? Our house was last rewired in 1965 we believe and because we are planning to be there long term, and wanted more than 2 single sockets per room, double lights and switch etc, we have had the lot re-wired. We also...

We need to run pipework down to the ground floor rads as part of a full heating system replacement. Edwardian property with good thick plaster and good bit rooms. Modern Viessmann boiler. Rads in one room are expected to be fairly large, something like 700x2000 K2 Stelrads, at just under 4kw a...

It might be that slowing the pump down would reduce the return temperature, its a system boiler so the pump internal and I've not had the covered off to see what speed it is set at. Obviously while a lower return temp may be better for boiler efficient, it will reduce the temp of some of the...

I haven't read the other thread in detail, but if it's a combi boiler using hotwater will divert the boiler to heat the water, and then turning the tap off will divert it back to heating the house. So it could be using the hot effects the heating noise in the same way as turning it off and back...

Surely you would buy an underfloor mixing valve separately from the kit. Thus getting the right hardware, outside of a kit, if the kit is priced silly or doesn't do what you want for some reason. It might that a TMV designed for a wash hand basin will give the same results as a simular looking...

Our plumber came round last night and looked over the job again now we have uncovered the pipes we can as part of the re-wire. Given the layout and the amount of compression fittings he has suggested we re-pipe the whole system including drops to each of the ground floor radiators in 10mm...

Not sure what you mean, we live in the house. Located on the Wirral. It's actually 17+2, I excluded the the two piggy backed extension rads, and there is one rad direct across the flow and return by the boiler, but get the picture. I have spent some time adjusting the balance and got it...

Often they are even smaller, 20mm solvent weld or the like. The main issue with running outside is also that they freeze, and they either stop the boiler running or ruin it, when the condensate backs up.

Typically fuses are there to protect the cable down stream from them. However in the case of incoming cables, they often also in effect protect the incoming cable. As said, its quite likely your neighbour has a 60 or 80 A fuse in that 100A rated cutout. Daniel

Very hard to say, could be the compressor, or the fan, or something slightly loose, but its very hard to advise if you can improve it yourself.

Depends what you want to do, you could buy a pair of secondhand power amps of email for not a lot of money and have have a speaker switch. All depends on the budget.

As said, should be fairly easy to connect the amp either to the computer audio out, or to the tv audio out. As said, if you are non bi-wiring you would use the 'normal' connections. However I am fairly sure on the A3/A5/A500 the terminals are just connected together inside anyway. Reasonably...

It came with the house, so somewhere between free and the cost of a 4bed semi, but the appear to be about £1000 depending what power you get.

I was going to say, surely the answer is 'your local builders merchant' to this question. Daniel

Sounds like £33m worth of admission they they did a very poor job of allocating the contracts the first time round.

If its just you, in a flat, no at risk persons, risk it till it dies? We have acquired a viessmann vitodens 100 in this house, seems nice and quiet, 7 years old and counting. Previous house has a main 30 he, unknown age but it did 7 years I was there without missing a beat, just a hoover out...

Anyone?

You can run it in the floor void, but it depends on the flooring type and which way the joists run as to if that is a practical solution.

Interesting, just had a quick look and chloramine appears to becoming more commonly used, and also a concern for lead pipes.

After some advice. I have recently traced all the heating pipes in our house and discovered it is plumbed as a one pipe system. There are actually in total five circuits each with there own balancing valve with only 2-3 radiators on them, it appears when new its was quite a high spec system...
