Check the diverter valve is operating when hot is on demand. Depending on the boiler [valve types differ] most have a small piston [biro refill diameter] protruding which operates an electrical switch/contact.
replace switch.if valve piston works but not the switch OR it piston not working
replace valve [or diaphragm inside]

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.

Why does my Takagi tankless water heater fire up briefly when any COLD water tap is opened? Unit is new; installed per mfr's instructions; works fine when HOT water faucet is turned on.


Because when you turn on the cold water the pressure drops in the feed to the heater, so the pressure switch fires the boiler up. Call the installer back.

Pressure gauge reading zero


Hello Mark
First of all turn on a hot water tap and keep it running whilst you check to see if your boiler is firing up, if it is not then try to restart it, you should hear the flame if its running, turn your tap off then just stand by the boiler for a few minutes to see if the pressure gauge starts to rise, if it doesn't rise you will never get any hot water, you will have to add some pressure to about 1 and a half on the dial, to do that is simply turn on the water valve in the bottom of your boiler and watch your pressure gauge rise to about 1 and a half then firmly turn it off again, it looks like a small tap like the one at the back of your washing machine pipe, it's ok you will hear the water rushing in, now with your gauge at about 1 and a half and your boiler running your water will get hot

You need to have the flow switch looked at. The low flow of the water to the lavs and the kitchen sink, they all have as small demand next to t bath or shower,

Our atwood heater is firing up ok and running for a good while then turning itself off but we dont get any hot water out of the hot taps. Our water pump is working ok but we have this funny tap within the...


Cold goes in bottom fitting of water heater, so that valve has to be open, and hot comes out the top, so that has to be open, if there is one there, but any valve in between needs to be closed. There are a few variations so if you can explain where your valves are located in the system more precisely, I can help better. Perhaps you can send a digital picture with reply?

Wont stay fired up


Bosch tech support will ask you to turn off the valve to the water heater and open a hot water tap. If you have water flowing it is likely from a shower valve. My experience is Price Pfister shower valves are usually the culprit. Let me know how this turns out.

Alpha 240e boiler wont fire up for hot water, will for heating


most likely the diverter valve.. when hot tap turned on the movement of the water through the valve operates a diaphragm which pushes a pin/button//switch to tell the boiler to fire up

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.
