from pic looks like cooper rising up, appreciate actually unscrewing anything looks like a nightmare, would be best to cut copper pipe and put a soldered cap on it (shouldn't use compression fitting unless accessible once done) sure ur gas engineer will know what to do when he looks, shouldn't be a ...
If ur hot water to all the other taps is hot and stays hot that discounts ur boiler, if the shower was/has been working fine since 2007 plumbing ok. It is common that the thermostat heads go on these showers, i would suggest ur best and cheapest option is to change the thermostat head on the shower.
u can get inter changeable heads! as long as the ones ur changing have the same diameter fitting as the new one; think lifestyle are inter changeable with danfoss/drayton? best bet take head into plumbing shop and ask!
recently purchased the above fire from b & q at knock down price due to coals missing (which have now been replaced) fitted fire, lights fine, but when u put on low, very low and then when put on high shrinks pilot then knocks off? checked the obvious blocked pilot, getting 21mbr supply to fire,...
no harm in fitting an extra air vent, if ur worried about failure, fit a manual one instead of auto air vent, u can vent it manually if required without the worry of it failing and leaking.
has ur boiler got a preheat function for the hotwater? If it has this would make sense why the boiler fires on and off, check ur manufacters to see if it has a preheat function. On most boilers this can be turned off.
It sounds like ur boiler is over pressurising then dumping, this is usually caused if the expansion vessel is flat (but it should dump out ur prv (copper pipe outside) if the connection is not tightened could be leaking internally (this would explain the high pressure dump), try running heating and ...
best thing to do is fit ur new boiler along with a magna clean (filter) this will protect the new boiler from the sludge already in the system. U can then add a sludge removing chemical to ur system, which will break up the sludge, then hook up the powerflush machine, clear the system, then add an i...
maunfactures will tell u clearances around boiler required, also take into consideration if the boiler needs to be serviced/maintained can access be gained! common mistake by kitchen fitters.
I would assume ur red is live, black is netural, bare is earth, and grey/green is ur demand wire, shouldn't be to hard as just need to connect demand wire, look at the back of ur new t/stat.
If ur cutting into the pipework on the central heating, you need to drain the whole system via a drainpoint, u can either turn mains stopcock or isolation valve on the header tank (small one for heating) to prevent filling back up!
Problem with shower, brand new. When u put power on to shower power light illuminated operates on cold, as soon as u turn thermostat to eco or high trips the earth protection on main board. If there was a problem with the mains/earth to the shower surely it would trip as soon as u installed the powe...
Feel the temperature of ur plate heat exchanger while running the tap, if it is red hot, but water from taps warm, heat exchanger blocked up and needs changing, could also be hot water thermistor need to check to see if its in range! 2nd option is the cheaper one!
