Hi sounds as though the system is sludged up & needs power flushing.the reason is that the water cannot circulate so over heats & pumps into the header tank.
expect to pay approx 350 400 pounds to have it properly cleansed, it will restore the system efficiency.
The other area worth considering is that it could be a faulty pump os that when th eboiler fires it cannot circulate so in turn expands & vents into the tank.

My advise is to arrange for a corgi engineer to sort it out for you.

Kindly

Richie

Very loud foghorn sound


Loud rumbling noises are often caused by either water boiling in the burner or by entrapped air in the system. To help prevent water boiling make sure that the boiler system has a pressure between 15 - 30 psi. Also check for sufficient water flow and remove any sediment from the in-line filter. To remove entrapped air, install an automatic or manual air vent at the highest point in the heating system and also make sure you have a properly working micro-air vent installed. With the unit turned off and cooled down, you can also try flipping the lever on the pressure relief valve to try and flush out any air in the heat exchanger . Hope this helps.

Every time we put on the central heating our water runs cold


What kind of water heater do you have?
In any case, it sound like a plumber should check out system.

Do you have indirect heater that gets heat from central heating boiler?
Most indirect/boiler combo heaters have control that is set to heat the water first.
If water is not getting heated, then the control needs repair.

Do you have gas water heater with gas central heating?
The central heater may be drawing so much gas from meter, that other gas appliances are unable to function. larger gas meter or gas line may be needed.
Or if furnace and water heater vent on same chimney, the backflow from central heat could be affecting burner on water heater especially if water heater has electronic sensor that stop combustion if air quality is bad. Venting problems can lead to CO poisoning, and are a serious matter.

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 need a diagram for an indirect hot water system heated by a solid fuel boiler and an oil boiler


If you are using more than one heat source you will have 1 more pump than the heat source pumps Main pump = SYSTEM pump pumps through the indirect hot water system and back into itself. This is the system loop. The other two boilers tee into this loop upstream of the indirect tank, downstream of the SYSTEM pump. The cold water return to each boiler tees into the system loop next to and upstream of where the hot water for that boiler tees into the system the loop. The oil boiler will have its own pump on its return line from the sytem loop and the solid fuel boiler will have its own pump. When any boiler fires, it turns on its own pump AND the system pump. If you want a drawing email me -pipesster@gmail.com send a fax number and I'll fax you a drawing.

Boiler Venting.


There cannot be controlled venting of the flue , the products of combustion must have free flow to escape , The heat exchanger is above the burner which heats the water if you thinks this is high then maybe you a pressure problem . Or contact the makes tech line and ask them what they think the consumption might be for you heater .You may find this on google

No central heating back boiler


back boiler run from a gas fire? check the instructions to operate the gas heat to the back boiler not just the fire
I presume that this a fully pumped system - air lock doubtful There maybe on/off valves on the pipes to and from the back boiler [situate close to cylinder] make sure they are on - anticlockwise turn
or there could be a blockage in the outlet from header tank usually in the loft. or If there is no water in it maybe the mains cold feed it is off.
Note if no water in it DO NOT USE the back boiler

My Central heating system as no vent


You are talking about a gas fired system I assume. So no, it's not a big deal. Code now states that you need to vent the gas furnace from the attic or a crawl space and not from the living space. They change this code back and forth all the time. It's nothing to worry about if you do not plan to sell the home.

Overheating


you could have a flow problem due to sludge or scale in the boiler, it could be a pump problem as it may not be circulating enough water around the system. or it could be a faulty thermostat if it is not cutting out soon enough.
1st try turning the boiler stat down to its minimum, if it still over heats then it is probably the stat.
if you have a switch on your pump to increase the speed make sure it is on setting 3. if the pump is old then it may be time for a replacement.

Very Hot water coming out of overflow pipe


Is your boiler heating your domestic hot water if so i would turn water off to water maker and see if your boiler pressure stays down below 20 psi. If so water maker is bad. The other thing that could cause this problem would be the boiler pump is out.

Open vent central heating


yes it is possible toupgrade the system to a sealed one using a system boiler as you mentioned. the thing to bear in mind is to upgrade the radiator valves to pressure rated ones 10bar.
The probable cause of the over heating is down to the system being sludged up/cold feed blocked, or possible pump circulating problem?
I would recommend the installation of a magna clean filter to help keep the new boiler clear from system debris.I would definately power flush the system, if the system is a twin two port valve system then a automatic bypass should be fitted, all of this done by a corgi registered gas engineer
