SOURCE: combi cutting out and overheating

is this a baxi 105? chances are you diaphragm has gone on your diverter valve. Or your diverter valve.
Do you will initially get a liitle hot water if your heating is on?

SOURCE: a trickle of hot water from taps, central heating ok

it sounds like your shut off valve might be bad even though it turns on and off by turing it doesn't mean that the washer is not stuck to the seat and not opening, try replacing the valve

SOURCE: Central heating and hot water have suddenly stopped working

not an engineer but maybe a heating compant,, it sounds like you have a relay that has gone bad, you have what we call a winter summer system your domestic water comes from a tank inside the boiler, you might want to think about splitting the system to save you some money in the long run, seperate the water heater from the boiler so you only heat up in the winter, right now you are heating the system that heats your house to get 30 or 40 gals of domestic hot water, it would cost you less by seperating them

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.

Pressure gauge drops to zero when hot tap turned on


There are multiple types of systems that use the configuration you are talking about. We have no way of knowing what the system is but there is obviously a supply problem. Either the pump is not working correctly or the water supply has been constricted.

When I have central heating on, why do I also get very hot water in taps even though water heating switched off?


This could be due to incorrect installation, incorrect wiring of controls, or an unintended consequence of combined central heating and hot water supply.

My central heating works fine but the tap water is just warm at best. You certainly cannot enjoy a bath!


Are we talking about a boiler situation? You mention "central heating" and tap water.

If it's a water heater separate from the furnace then I would say a element going bad, assuming it's a electric water heater. If it's a single boiler unit, I would have to say call a service tech.

In either case, you will need to post more information regarding the equipment before a reliable answer can be given.

No hot water,central heating is fine


Sounds like the output fitting has melted inside and clogged up the output pipe. These couplings are one way valves to keep water from draining backwards when not in use to keep from burning elements. They are plastic inside. I would turn off water and replace those after a visual inspect if needed.

Sounds like the by-pass valve diaphragm. This valve detects that hot water is being drawn off at the tap and then diverts the mains input water across the heat exchanger. Very often it's the diaphragm inside the valve which is punctured or split.This can be replaced [depending on model] if you take apart the valve
. Remove the front panel and lower the control panel.The valve is at the bottom left of the boiler
Suggest turning off the service taps to the two heating pipes and the cold mains inlet pipes before tackling the valve
