Hi all. In new flat for a few days now, kitchen has a kind of lighting strip which incorporates 3 halogen bulbs on a rail. They have a standard light switch. All other lights in the house are normal bayonet bulbs. It was all working OK until today, when they suddenly stared dimming, and in...

For me: +++++++++++++++++++++++++ Boiler cost £xxxxx + £15 Installation of boiler & Powerflush: £870 TRV's: £18 each (Danfoss Ras-C2) New 22mm gas pipe £ ????????????????? +++++++++++++++++++++++++ Please let us know how far it is to the gas meter, or to the nearest 22mm gas...

I'll stick my oar in here... BigD, have you tried running the system on HW only for a period of 1-2 days, and confirmed 100% that this only happens on CH call? As this boiler is a heating boiler its PCB cannot differentiate between CH and HW call. If it is really happening only when CH is...

Never more than £300 eh? Maybe for one repair, but in a 10+ years old boiler which has been neglected for all of its life and never serviced he may find himself paying another £300 shortly after, and the thing will still be a noisy old wreck! I bet that no-one but Heat-team could those...

The people here will need more info than that mate. Need to know: Exactly what you have got, ie what kind of boiler you have at the minute, are there TRV's everywhere, what size os the gas supply pipe to the boiler, can a plastic overflow pipe be run for the condense easily? Lots of...

18.9kw coil, reheat time 15 mins. Suppose if the programmer is set correctly then even if 2 showers taken one after another, the second one should be hot by the time its taken.

Are there any other of this type of shower with integrated diverter that people would reccommend? I'm loathe to tell this guy to go with an unbranded one such as the one in the link...

Thanks Chris, Mains is approx 2.5 bar working pressure, minimum of 22mm pipework from stopcock up to shower, then reducing to 15mm. Cylinder is a Range Tribune HE, P red V set at 3 bar for these I think. Thought that a 150 l capacity cylinder might just do it but if the flow rate is over...

What approximate flow rate would a shower such as this be capable of delivering: http://www.bathroomheaven.com/sp_showitem/2849 I expected around 15 l/m, but a colleague has suggested that they may be much higher (around 28 l/m). Can't find contact details for the manufacturer. Trying to...

If you have the space you could fit it on a cut paving slab, with four 1/2 squash balls as feet to deaden the noise...

This is the consumer unit we have in at the minute. I don't know if they still make them this small, its just that if we put a new one in we may not be able to fit one which is any larger: [/URL][/img] (its the top one thats ours - upper flat of 2) Does it look like it needs replacing...

He means a heat exchanger like the Puma, which has 4 pipes (2 x primary and 2 x mains water), mains water is directly heated by the burner.

Not sure that it does tony. I think it has a plate to plate.

I'm a non-part P gas-fitter, so not great on the lecky regs and need some advice. Going to get my flat (built 1910 ish, converted in 1979 to 2 flats) re-wired this summer, and I was wondering if the supply cables to the lights (which are run through the loft, currently not clipped or trunked...

Gas fitter here 25mm from any gas pipework is the answer.

I think I'm going to put one of these in my place, they look great. Saw them at the PHEX, but no experience of them in a work environment...

On this type of heat exchanger you could probably fashion something to attach it to a powerflush machine I suppose, but I actually meant closing the boiler off from the CH system, introducing some chemicals and running the boiler on DHW demand, then when heat is applied the chemicals would...

Its not an ideal pump head is it? Had to put one of these in a Worcester 24i with the conversion kit for Grundfos pumps the other day. Took 4 goes to stop the b'stard leaking and then when it went on it didn't work!!!?!?!?!?!!! AAAAAAAAhhhhhhh :x

Spoke to Thames water about this, and the helpful person on the line said that I might qualify for the lead replacement scheme. Anyone here had any work done under this scheme? Are they likely to charge me? Oh, and hteng, was that £1000 YOUR fee, or what the water board charged?!

Before you do anything you need to see if this new pump is itself turning. This is a simple job, just undo the nut on the pump if it is a Grundfos, and put a smaller screwdriver in the hole, if there is a grinding noise then it is turning. Next, turn off the power and with your smaller...
