hi you dont say whether you have cold water coming out the taps ??? if you have then i would check to see if there is 240v to the heater first check that mains is to 1 side of the stat then turn up the stat see if it goes to the other side if it does then its the element that has gone ...

it sounds like you have a problem with a motorized valve on the hot water side that is stopping the water from going around the cyld, have a look on the end of the valve there is normally a manual position for imergencies pull over the lever and push into the slot, it should work, if so then...

it sounds like you should have used a negative head pump

as the other poster says just wire up the bottom one just means you will get a ful cyld of water, other than that i have removed them by using a bolster and a hammer and give the large nut a sharp tap in the right direction, that usaully is enough to release the seal then you might be...

i am a bit confused with the problem your having with the ravenheat 100e you say its ok when its on the sink tap ??? and does it shut down then ???? what type of bath taps have you got are they combined bath and shower taps??? and are the sink taps that its working ok on a mixer...

sounds like the diaphram needs changing on the domestic valve they only seem to last about 2 years normaly so you are lucky its lasted that long

hi most ravenheat boilers especially the 820/20 always revert back to the heating after the water has been switched off, there are 2 micro switches on the back of the diverter valve one is normally open the other normally closed so when the tap is turned on the heating one opens...

you are correct it does need a long box spanner they are available as a set of 2 from most plumbers merchants

using a surrey flange will not work what you have is a secondary return so the hot water is always circulating in the roofspace therefore when you pull the hot water off your only drawing it from where the secondary is teed into it therefore without drawing loads of cold...

get yourself a leadlock fitting they normally either go to 15mm or 1/2 bsp be carefull not to leave a long dead leg cut it back as short as you can you might have to take a small peice of the lead with you as there are 3 sizes

you can actually buy 3/4 20th to 22mm soldered fittings i have used them you can get 1/2 20th as well to 15mm i made myself a bumping tool that expands the 22 out to fit 3/4 20th have a shop round i think plumb center used to keep them

the normal practice was to supply a permenent live to the boiler and a switched live to the boiler from the programmer, the pump is wired into the boiler pump connections on the boiler connection strip, the ranco stats had a changeover built in so leaving the pump running for 3 mins...

hi have a look at the pipe comming out of the bottom of the cylinder follow it allong and see if there is a gate valve fitted?? these were fitted to slow the return down so it did not short circuit though and shut down the boiler on the stat before the heating is satisfied, it was...

I think the best way to do it is to disconnect the internal clock , and then use a 4core plus earth cable supply a new clock with zero volt switching, you will be able to use the mains feed to the internal clock on the boiler for the mains to the new remote clock then connect the...

hi its not a big job all parts are available for H R PC but as you have a contact with BG i would have thought they should replace it anyway it means draining the boiler and turning off the cold feed to the boiler and draining out the pipes with the hot tap...

i had a problem with one of these boilers i think they must have been the worst boiler gloworm ever made any way i replaced the plate heat exchanger for a new for the customer, and no problems after that sometimes flushing is not all its made out to be its ok for rads and i...

hi it does sound a bit like the expansion vessel has not been set up properly , i think they should come back and discharge the system and check to see what pressure is in the vessel it prob just needs pumping up a bit, what can be happeng is that the diaphram is sloppy because of...

hi the cold feed should never have been fitted to the mains for the shower anyway both the hot and cold should be fed from a storage tank because if you were in the shower and someone turned on the cold mains you would get scalded with the hot water alone but if its on a storage tank...

Hi it sounds like the heat exchanger is corroded up could be just limescale or it could be debris from the system i suppose you could try power washing the system out and descale the domestic part of the heat exchanger but its not cheap around £500 whats prob happening is after running a...

hi this model boiler is a positive case and he is correct , i normally test it with a smoke match you can only use a seal thats made by the manufactures if its still available , the reason he has told you you cannot use it is because fumes are entering the room,so its classed as I D
