Sounds like a stuck expansion valve, the compressor makes pressure, but it can't be released to absorb heat from the desired environment. You could go to the manufacturer's website, request a detailed diagram of your system, find the expansion valve and order a new one. Can you put it in yourself and recharge the system? Probably not, call a repairman.

Peerless Boiler - Turned off boiler to replace Circulator for the hot water. Turned furnace back on. Did not ignite. Tried to hit the reset button for 30 seconds and nothing happened. Furnace will


Did you bleed the air out of the pump. The boiler has a flow switch that has to make before it will let the boiler lite. Make sure you have all of the air out of the system and are pumping or flowing water and not air...Also check to see if you didn't happen to of tripped the limit it has a manual reset. Red Button on the front of limit.

I have an old solid fuel fire with a back boiler behind it...the pump is making a buzzing noise....some radiators hot some not...please help


Tell us more: What is the Solid Fuel?-- Coal?-- Wood? Is this a Steam boiler?- or a Hot water boiler?-- It sounds like Hot water, for you mention a pump-- Perhaps it is a Hot Water Circulation pump?
Does the Boiler have a sight glass?-- What is the water level?
Tell us more, so we can help you figure things out.

Espresso machine HISSING!


It sounds like you have the cup warmer turned on. But if that's not it there is a leak in a connection coming from the bolier. If you open it up it will be obvious where it's at. Don't wait too long because the moisture will effect the electronics.

Glowworm boiler making noises


You're probably getting what some call gurgling sounds because there is air in the system. You need to bleed the air out at all bleed ports starting with the lowest in the system and ending with the highest.It won't hurt if you do that process a couple of times. Once all the air is out, you should have a normal convection flow of water through the system. - Good luck!

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)

We seem to have developed a problem with our boiler, worcester 20/25 heatsave. Every time we turn on a hot water tap, when we turn the tap off, there apears to be a loud noise from the boiler or pipes for...


it seams the valve that senses water flow is not operating properly,causing the boiler to keep heating the water when it has nowhere to go,i,e the taps turned off,thus boiling the water.
