I got htp boiler combo the boiler make domestic hot water and no heat, termostat good relay good,any parts got be replace.


If you have replaced all parts of the boiler, then there is a water leak somewhere in the system. This applies to flow water heaters. Water does not get warm up then. Perhaps the burner was blown, if you did not check it.

I've got a Worcester Bosch boiler had a leak In the pipe On the landing so a friend emptied the boiler an I fixed the pipe but I don't know how to refill the boiler


Can you get the manual online? You have the Manufacturer info so you probably have the model number too. I found a manual on Manuals.com for my boiler so they may have yours too which will hopefully have some information on filling boiler although I realize each installation is somewhat different but that's why it's difficult to answer you question. Usually there is a manual pressure valve that regulates the water pressure in the boiler which is usually pretty low...like less than 20 lbs. The manual should tell you the pressure as well. But this pressure valve has a flip handle that comes off the cold water line to the boiler to do just what you want to do...refill it with water. When refilling the boiler (if you find the valve, you may have to purge the air out of the lines which there is a whole other process for. But you shouldn't allow cold water into a hot boiler...it could crack it when the cold water hits the hot cast iron. So make sure the boiler is cool when filling it up.
Now go try to find that manual!

Gas boiler leaking


The video zeroed in on a relief valve. They love to leak once opened. If it won't re-seal after you lift the little handle and let out some water, you will have to replace it.

Ravenheat 80/20 boiler. the boiler looses water pressure but only when working in central heating mode. Boiler holds pressure indefinitely if central heating is not used,hot water can be drawn without a...


Hi, your boilers pressure should be holding 1.5 bar with the relief set about 3. If the pressure is below this the flow switch will cause the boiler to stop as theirs not enough pressure to operate. Another thing, does your boiler have an auto fill system or do you need to plug a hose in to fill it? If its an auto fill system and you lose pressure you could have a leak.

Water to hot for gas boiler boiler gos off


It could be dyslexia, but I think you want to know what may be wrong with your boiler in this case!
This is a VERY old design. The diaphragm is on the water section, this operates a switch to turn ON the pump, and a further device causes the diverter valve to divert boiler water from CH duty to HW duty.
From your description it appears that the boiler is shutting down on internal boiler water temperature (too high), your 'briefly too hot' HW symptom may be caused either by the boiler side of the secondary heat exchanger being blocked/caked in sludge, OR the DHW side of it being scaled. Either way a new or replacement (descaled) secondary heat exchanger MAY inprove things. It's not easy on these old clunk-pots, and EVERY disturbed seal will subsequently leak, so get a good supply of o-rings and fibre seals before you start ("you" being the competant fitter you employ)

Boiler leaks when shut down


Hi,
I hate to tell you this but you probably have a leak in the casting of the boiler...it is very slow... therefore the water will evaporate as long as it is hot and you do not see the water...but if you let it cool , not only will the casting shrink and open the hole a bit, but none of the water evaporates....
After 35 years it is time to replace that boiler...

I have a alpha cd32 boiler,and i keep having to top the water up within the boiler,so to get hot water and heating again.i have checked for water leaks and nothing is found,however i did check the outlet...


Pressure relief valve - replace
The internal seal gets bunged up with dirt & scale and then leaks water [pressure] to that outside pipe
To avoid draining the whole system, turn off the two central heating taps on the 3/4 pipes and then operate the valve manually and / or disconnect - only a small amount of water will escape / drip to below the boiler
Replace valve and fill as before.
If you think your system needs flushing out - now is a good time
Turn off mains electricity to boiler before starting work

Boiler pressure


If there is no leak anywhere in the system [pipes & radiators] Check the emergency pressure relief valve. It usually is at the base of the boiler and drains to outside [15mm pipe] where, if the valve leaks, water drips can be seen.. Looks similar to the picture with your query
Renew the valve
You can take it apart and clean it but I've never found that to be successful in the long term
