SOURCE: The hot water and central heating wont work together

what size of gas line is going into boiler and water heater? is it black iron ? natural gas or propane? have you checked gas pressure at water heater and furnace ? if they work fine individually then you have a problem with incoming gas pressure. Call gas company and ask them if they would come out and check gas pressure.

SOURCE: hot water boiler will not ignite

Check all your limit switches on this unit. One of them is either tripped or bad.

SOURCE: no hot water, pilot light lights but no burner ignition

Thermo coupler may be defective. it controls the main gas valve by closing main if pilot is out. make sure thermo coupler bulb is positioned over and near tip of pilot flame, but not in the flame. Thermo couplers are inexpensive and easy to change out.

sounds like the gas valve to me you need to see if the appliance is sparking 1st if it is then u need to check wether there is the right voltage going to the gas valve according to mi manufactureres instructions normally 240 volts ac if there is voltage then the gas valve is sticking get back to me after your findings

The hot water temperature is not constant with the burner shutting off


You can get a sound like that when there is too much sediment in the bottom of the tank. Turn it off drain and flush it until the water runs clean.

Glow worm 45-60 standing boiler making banging noises when in operation


The noise you refer to is called Kettling, it is caused by the hot water in your boiler not being able to leave the boiler quick enough, if the problem developed quickly and your system is a "fully pumped " system this would generally point to your pump either has failed or is on its way out, i.e . your radiators would not heat up as the hot water is stuck in the boiler hence the banging......( if you know where the pump is you can generally feel if it is running by a small vibration ) if you have gravity hot water and pumped heating circuit then I would assume that it is noisy when just doing HW, and the banging is a problem that has gradually got worse it can indicate that the boiler is scaling up (are you in a hard water area). if this is correct there are various additives that can be put in the system to help quieten it down, I suggest you really need a heating engineer to diagnose fully.

Amtrol wh-7p


The tank rusting itself shut is almost an impossibility due to pressure. I would be inclined to believe that the controller is starting to fail and water that was way too hot entered the system and caused and overpressure issue that made the leak, When the pressure and temp dropped, the problem subsided. According to some of the threads that I have found on this, Amtrol is pretty generous about replacing the defective parts even when they dont have to. http://www.doityourself.com/forum/water-heaters/335226-amtrol-boilermate-problem.html

Wickes 102 combi boiler constantly loosing water pressure


It sounds like your thermostat could be the problem. Have you noticed the boiler cutting off at all, or does it run continuously until it goes out on low water?

You stated, "when boiler is on", so I am wondering how you get the boiler on. If your boiler is controlled by a thermostat, you need to check it for a cold draft possibly from behind the thermostat in the wall where the wires come through. The thermostat should never be on an outside wall. The thermostat could be defective.

An aquastat can also control your boiler. If you have an aquastat, check the setting, typically 175 - 180 degrees. You should also have a "high limit" which should be set at 210 - 220. Some people run that high side limit higher; not a good idea - defeats the purpose. If the aquastat is set too high, the boiler will operate too hot and the problem you have will occur.

"pressure rises and pressure relief valve opens" This could mean that your pressure switch is prematurely venting. Check boiler temperature to see exactly at what temperature the T&P valve purges. If it blows off below the high side setting, either adjust or replace. The T&P valves are usually not adjustable. That blow off temperature is stamped on the head of the valve. So, if it discharges too soon, replace it.

Have you actually seen evidence thgat the T&P valve is opening? You may have a bad bladder in your expansion tank and your system may have air in it. Your boiler should have 12 psi when cold and 20 - 22 psi when operating. Check your boiler pressure guage.

"
this eventually drops below the minimum operating pressure" Technically, there is set point for a NO MINIMUM OPERATING PRESSURE. That is a function of the amount of water in the boiler. If the T&P is blowing off, it will vent water from the boiler and the boiler pressure will go down. There is a minimum operating TEMPERATURE.

Your boiler could be low on water. You will have to manually fill the boiler. Be careful of thermal shock to the boiler. Feel the piping, and fill only when the circulator is running. Make sure the water is not going directly into the boiler. The supply water should go into the circulating supply side which feeds the radiators, radiant floor, or base board circuits.

All this will adversely affect your hot water. The heat exchanger for the potable hot water may have scale build up in it. Using the hot water keeps the boiler running, and a scaled heat exchanger will give you cooler hot water and the boiler keeps running. If this is a problem, you will need to replace the heat exchanger. A better idea is to not use the boiler for your domestic hot water. Why run the boiler in the summer?

I have a riello 40 burner it fires for 2 seconds then cuts out what could be the problem


If it actually fires up and you have a flame for 2 seconds and then it shuts off, I'd bet that the photo cell is either dirty or has failed. If it is dirty, it suggests that the burner has been neglected for some time and probably is in desperate need of a tune up. The photo cell is located under the ignition transformer and is aimed into the combustion chamber to see the light created by the flame from the burning oil.

If it is clean, the photocell has likely failed and will need to be replaced. If it still runs the same way after photocell replacement, it is probably related to the primary controller or one of the other safety devices. Is this a forced hot air or hot water system?

My boiler keeps running even with thermostat removed from circuit. It is a Raypak H1-133A thermionic heating system (pipes in the floor) about 15-20 years old. (thermostat is original, 50 years old).


I answered you previously with information that didn't help. I'm not answering for the $5, but to try to help you. It's been several days and I assume Raypak is not helping.
Possibly the thermostat closes a relay that is on the main control board, maybe this relay is stuck closed. Can you follow the wiring from the stat to the controller? Something in the controller is thinking you need heat.

Fan runs continuously


the air pressure which does not controll the fan it is a safe guard for the gas/oil burner to ignite nowing that the fan is running ( air switch normaly negative /positive prssure n/o,n/c circuits. it could be that your boiler is designed for a cant think of techinacal name but when in centre of house/factory and has 1 or more boilers connected to flue etc the fans run when only power to boiler is on , non vented system ? it could be a simple link to remove in controll panel i would phone technical help for manufacture ?

Hi Jurgie,
I'm Harvey, the Master Plumber,
Happy to render my assistance.

This is your problem!
When you are switching on the boiler it ignites for 8 to 10 seconds, then it cuts off and the lock out lamp comes on. Pressing the reset button or turning on the hot water tap has the same effect.

I need to get the make and model of your specific boiler to give you an accurate answer!
Waiting for your response.
Harvey, your Master Plumber.
