Many times the factory wiring on the boiler is set up to maintain boiler temperature with a built-in aqua-stat. The thermostat then controls the circulator pump to transfer heat from that loop to the structure. So, if this is the case, your programmable stat may just be controlling the circulator. There are many, many control AND piping configurations to boilers. Some very different than others.

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.

My Baxi Combi 80e boiler turns the heating on randomly. With the wall thermostat turned down and even with the boil switched to hot water only the heating still fires up when unwanted.


If the thermostat wire run passes anywhere through, beside or inside any metal surfaces and the wires touch any of the metal its the same as if you turn the stat to on. I've seen this a few times. Easiet way to detect it, if its inside the house is at night in the dark. Look around when its doing this you may see the small spark when it goes on. Otherwise you will need to inspect the entire run from the stat to the untis, etc.

You should have a remote heat setting via a wall or on the front of the boiler dependant upon how it is set up. If in doubt as a Central heating engineer to install a remote one you can have next to you wherever you are in the house.
