I think Trianco got stuffed by having to make a band A oil boiler. When I was there three years ago they did intimate they were having trouble reaching efficiency levels, and it seems they never got over their design problems. Where I used to work we used loads of the old Eurostar non...

Is that 2 hours from experience or just a guess. I recently did 12 TRVs on microbore in a very clean house with the whitest newest carpets you ever did see. It was a 2 day job (downstairs day 1 upstairs day 2), but leaving them with system working at end of day one. Just sheeting up the carpets...

I've found drayton TRVs over priced and fall to bits with age so I don't use them. I recently fitted two houses with Siemens TRVs . They are neat and seem quite well made and come with 10mm adaptors in the kit for microbore (I ordered Danfos RasC-2s with the 10mmm adaptor. When they came...

2 Adults 2 Children is pretty well ideal for a combi. Thats what we had in our previous house for ten years. However if you are talking en-suite bathrooms and lots of hot taps etc, then forget a combi. Ours was a three bed detached with three hot taps and a shower all run off the combi. It was...

If people ask questions on this forum they are entitled to an intelligent answer. In many cases apparently simple questions reveal complications they had not considered or appreciated. I reckon that this forum helps many people decide NOT to try DIY in a lot of cases. I did not train to be a...

I'd go for the latest Honeywell programmer. It has pre-programmed date/time in it, has automated daylight saving so it goes 1 hr forward in spring and an hour back in autumn, nicely backlit and easy to programme. I'd go for a simple honeywell stat too unless you want a posh digital or a...

Or even an exploding Fortic Primatic..... :roll: Alfredo

We started fitting Grundfos Alphas to existing systems on our breakdown contracts a few years back. It was not a successful experiment as we found they tended to run too fast on the variable setting, and cause all sorts of niggly problems, so we ended up setting them up on manual speed 2 after...

Thankyou......brain currently on holiday...normal service will be resumed soonish :oops: Alfredo

Bit of a silly question I should know the answer to, but dont. I removed an old washing machine and installed a new one today. The new one is cold fill, so old hot connector tap is redundant and I want to cap it off in case tap gets turned on by accident. What size cap will seal it off...

I went to one of these leaking from just about every orifice. It turned out the schrader valve had failed in the pressure vessel and everything was being pressured to 3 bar. I new valve from local garage (£1) repressurised to 1 bar, tightened a few things. No more leaks. Alfredo

Sounds like you need somebody to fault find and service your existing boiler as it should provide decent HW upstairs without needing a new boiler. Alfredo

Its still getting a signal from somewhere if the buner stays on. Does your system have two two port valves or a three port near the cylinder. It could be that this is stuck in a demand position and completing a circuit. Either that or the programmer is jiggered..you might try a reset if it has...

I think its boiler stat too. Best DIY test is to turn the boiler stat down to close to its minimum setting without turning it off and seeing if it does turn off the burner eventually. If it doesn't and you get nasty boiling noises again...its the stat. X400 not strong enough? Hmmm. On about...

Well you could opt for death I suppose, but a new boiler is usually the more popular choice :wink: Alfredo

Combis are effectively a complete heating/Hot water system in a box, so there is more to go wrong, and more electronics to control them (usually) The burner/gas valve side is no different as a rule. In a combi however there is a diverter valve to switch boiler water from CH duty to HW duty...

Boiler pressure gauge should be on about 1 bar when cold (or in a greeen sector not red). If it was high before you started the boiler then of course the Pressure relief will release excess (dangerous) pressure. When cold you need to make sure the filling loop is closed and release pressure...

No two TRVs turn off at exactly the same temp, they are a bit of a blunt instrument, and sensitive to draughts and other influences. Having said all that it is possible the pins on the TRV valves are sticking, so unscrew and remove the thermostat heads and give the exposed pins a few sharp...

Well the FIRST thing I'd do is have a look at the Land Registry map and make sure the boundary is in the right place, just make sure the fence follows the boundary. How do I know to check this? When we were working away a neighbour erected a fence that made my garden about 15%...

I'd get on to manufacturer of the cylinder and complain like mad. They should last way more than 7-8 years. If not a free replacement I'd be pushing like mad for a generous discount on a new cylinder. http://www.telford-group.com/default.htm Given that the boiler is 7 years old, and...
