Question about Water Heaters

Ariston Combi euro boiler SX20 MFFICE 970903039 GC No 4711602

I have the above boiler which comes on as normal and the temperature gauge rises anything from 40 - 60, the boiler cuts out all the time and the red warning light comes on and I have to press to re-ignight the boiler. Could this be the therma couples which I understand there are 2 of? For your information, earlier this year I had a new expansion vessel.

Any help would be much appreciated to get it working.

Many thanks
Glynis

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?

Baxi boiler 80E low pressure on boiler how to fix it?


Silver flex hose may be the (correct) filling loop. There may be a valve at each end of it, maybe just one at one end.
Open the single valve slowly and LISTEN for the sound of water entering the system, and LOOK for signs of the pressure gauge rising.
On the dual valve version open the first, then open the second slowly as above. Close both valves when pressure is adequate. Adequate is determined by the specifics of your system, but note that more pressure DOES NOT mean better showers, etc.
It should only take a few seconds to top-up, any longer indicates a significant loss of fluid from the system.

Pressure gauge reading zero


Hello Mark
First of all turn on a hot water tap and keep it running whilst you check to see if your boiler is firing up, if it is not then try to restart it, you should hear the flame if its running, turn your tap off then just stand by the boiler for a few minutes to see if the pressure gauge starts to rise, if it doesn't rise you will never get any hot water, you will have to add some pressure to about 1 and a half on the dial, to do that is simply turn on the water valve in the bottom of your boiler and watch your pressure gauge rise to about 1 and a half then firmly turn it off again, it looks like a small tap like the one at the back of your washing machine pipe, it's ok you will hear the water rushing in, now with your gauge at about 1 and a half and your boiler running your water will get hot
