Question about Heating & Cooling

1 Answer

I have a Valiant boiler which supplies radiator heating and hot water. There is an intermittant fault which has occured over the last couple of weeks where there is no hot water coming from the taps and a very low pressure of water coming out of the hot taps. The boiler pressure is okay. Then after a couple of days, it corrects itself, then the hot water goes again. Now it has occurred again over the bank holiday and I am unsure whether to get an emergency boiler engineer or a plumber. Could it be a faulty boiler part or a leak, but if so, why does it get better? Thank you soosywhit

Hi,
The problem seems more likely to be a plumbing problem....
I would call in a plumber to chek to see where the blockage is.... there seems to be something stuck in the piping that is causing an intermittent problem... to find it the problem will have to be occurring then the the plumber will have to trace back through the piping till he finds the source by seeing where the good pressure stops at....
It would seem to be something like a bad vlave that is floating in the piping or like a coin in the piping that flips around and can open or shutoff the piping....believe me strange things like that DO happen....

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?

My valiant ecotec pro24 boiler wont heat the radiators up,i hav hot water.i just got new meter fitted 2nite+its been 10month since i last used my gas,my pressure is 1.6bar but just cant get heat from...


Have you checked automatic air bleeder on main supply line. I would make sure it is working and bleed each radiator if possible. If you haven't used heat for 10 months I would suspect a build up of air in system. I hope this helps you. Thanks

I need to power flash a vaillant boiler. can you please help. water goes hold and cold, sometime the heating stop but the water works and vice versa. i was told by an engineering that it needs power...


Hi

Although not a PC problem, i have had this same issue on my Vaillant Boiler, the problem you are describing is not a power flush problem, you need to clean out your exisiting diverter valve or purchase a new one

The diverter valve is repsonsible for either providing hot water or providing hot water to the central heating, when this valve gets stuck in between the symptoms you have described above occur

I would also not recommned that you do a power flush yourslef as you may end up damaging the boiler and its pump


If this has been useful please leave postive feedback/vote/testimonial - Thank You Again - shauqatm@yahoo.co.uk

Hi there. Our valiant boiler doesn't seem


Lack of pressure in the primary circuit [radiators] Look for a pressure gauge should read between 0.5 & 1.5 bar
Somewhere there is a tap/valve/pipe connection to refill & looks like a small thumb turn or a screwdriver turn on a connection on the mains water inlet pipe. turn on until you get the right pressure then off

Heatslave diverter valve


clicking rads are due to pipe expansion when getting hot.
If the hot water [secondary circuit] gets hot and the boiler stays on [does not keep going on and off] even with a constant low water flow then the diverter should be ok.
there is a valve to prevent the primary circuit [central heating] [ CH] from sending water to the rads. this or its control may be at fault.
both the
Both the CH pipes to & from the boiler should have manual valves to turn off. do this then try the hot tap-full on. If the boiler goes into overheat mode and the overheat stat kicks in to turn the boiler off -- then :-
Check also the heat exchanger, it may be furred up especially if you are in a hard water area. It means taking it off and manually checking [pour water through] If you're lucky it will be just muck to be forced out with hose pipe pressure, if not a new one
