Question about Water Heaters

The hot water and central heating wont work together

The heating has been fine for two years - then the boiler would not ignite if both the hot water and the central heating were to come on together, they both work fine individually. I had a plumber look at the boiler and he said the boiler was fine but I needed a new programmer. I have replaced the programmer with the same model, as i was told I could leave the back plate on - and still it does not work - any ideas

What size of gas line is going into boiler and water heater? is it black iron ? natural gas or propane? have you checked gas pressure at water heater and furnace ? if they work fine individually then you have a problem with incoming gas pressure. Call gas company and ask them if they would come out and check gas pressure.

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.

Honeywell T403A1174 suddenly doesn't appear to call for heat


some times inside the boiler on the internal pipework you will see little sensors, on the central heating piping there sometimes is a thermastic sensor on side of flow pipe with a little reset button on ? i guess with the problem you said the poiler locked out and the pipe work overheated ? this is a safety feature on some boilers not, all and easerly reset via this button ?

Valient combi boiler is not heating the water properly


vailant boilers are one of the best on the market and should last you more than 6 years depending on installation and servicing.
the engineer you had should not have replaced the diverter valve if the boiler was firing up when the taps are opened. if you was getting luke warm water with the boiler alight it is a classic symptom of a blocked plate heat exchanger on the central heating side.
a new heat exchanger can cost around £100 depending on the age and model of the boiler.alteranatively it could be descaled but may clogg again. it would be a good ideal to fit a magna clean filter on the system to help prevent further debris if you have a dirty system .if you don't trust your engineer i suggest you ask another. find out if he is registered first and don't pay until you are satisfied with the work. if you are asking the same engineer back try and get a discount off the work as he has failed to rectifiy the original fault and fitted the wrong part due to wrong diagnostics. if he is registered you can complain to the governing body ie corgi or gas safe register.
good luck.
