Open vent central heating

Is it possible to upgrade a open vent central heating system by
installing a sealed system type high efficienty boiler in order to eliminate the need for a expansion tank in the loft due to the numerous
times the system has over heated and vented steam and hot water.
surely its just a case of installing a new boiler ,using most of the existing pipe work ,rerouting new pipe work,and possibly the need for a
power flush.

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

Boiler won't ignite for hot water unless heating is on.


If this is in a RV the propane monitoring valve may require more gas flow to turn on than the water heater requires. A central heating system requires substantial gas flow so when the monitoring valve opens to fire the central heating, there is enough gas flow to also fire the water heater.

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)

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.

Radiator heats up when running a shower.


Your boiler is overdue for a service.

Combi boilers are unlike regular boilers in that they have quite a few moving parts, it's vital that these are serviced annually if you want the boiler to remain reliable and to avoid expensive failures.

In your case, the diverter valve has most likely failed. Normally, when the heating is on this senses when there's a demand for hot water and temporarily diverts the primary hot water circuit to feed the domestic hot water heat exchanger. When the demand for hot water ceases the primary hot water circuit is diverted back to the central heating heat exchanger. The valve has a number of moving parts including a rubber diaphragm which can wear out and split and moving shafts which can seize.

When the valve fails it can leak and also can divert hot water to the central heating heat exchanger when hot water is used. The reason that only the highest radiators in the system are affected is probably because the failed valve does not necessarily cause the central heating pump to activate and circulate the hot water throughout the system (it does on some boilers though). If hot water is introduced into a cold heating system it will rise via convection to the highest points in the system like an old fashioned gravity circulation system which was unpumped.

Call a heating engineer out as soon as possible; I'm not going to advise how to do the repair yourself as gas appliances MUST be serviced by qualified persons only for reasons of safety. If you're lucky then the valve simply needs cleaning up and a few new diaphragms plus other minor seals and rings. If it's gone too far then the valve and possibly the manifold it's attached to will need to be replaced.

In the UK the part alone typically costs between £100 to £200 depending on whether it's just the valve or the manifold as well. The diaphragm kit typically costs up to around £15 and is routinely fitted when the boiler is annually serviced, and a new valve will already have new diaphragms fitted. For a routine service expect to pay for up to two hours labour (many can be done in one hour), but if the valve/manifold have failed it will be longer as one failure often causes other parts to need further inspection/repair.

I hope that I've helped you today, if so please return the favour by rating my answer.

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.

Combi boiler no DHW


if the boiler fires when the tap is opened then the diverter valve is working ok it must be a blocked plate heat exchanger which is the stainless steel rectangular block inside the boiler connected to the pump and the mains cold water.
it will be blocked on the central heating part probably with black scale. it is possible to clean out but sometimes it is better to just change the plate. but remember to flush the system as well or the same thing will happen.
