Re: When does your Heating usually go on?
 

Yes. The electrician said do you want it set to how it is now after he removed the old kit. I said no thinking it'll get too hot but that's not the case. I've since gone up one to 22c on the thermostat.

My boiler is behaving differently with this new kit. It's running a lot more efficiently and is condensing more. My previous kit would fire up the boiler and let it reach max temperature levels set at the boiler. This new kit is only reaching temperatures in the 40's which what the installer of the boiler 10 years ago told me, 'let the boiler run on constant in the 40's' for low bills and comfortable temperatures. The thermostat obviously dictates the off and on temperatures. Impressive thus far.

The heating was busier last night, coolest night since before summer.

BREAKING NEWS: My heating went on today. Over ruled it and switched it off, it was being over dramatic.

make sure you wake up with both testicles in the morning;)

The room thermostat is one in a chain of switches that need to be "closed" for the system to burn gas.

With the Boiler Controller timer set to "on", by being set to "constant" or "timed On":

Gas pressure OK
Water pressure OK
Flame lit and stable
Air pump OK

It will run the circulation pump without burning gas if the water is hot enough and the thermostat is closed.

I appreciate the breakdown :tu: you say thermostat closed twice to do two different actions though.

SnoopZ, 22c is perfect thanks :tu:

Re: When does your Heating usually go on?
 

2 situations: burning gas, and not burning gas.

The latter can cause confusion, as people think that flames will erupt as soon as the room thermostat trips on. That won't happen until the boiler internal thermostat detects outgoing water under the set temperature and with the circulation pump running.

If you listen carefully, you will hear the circulation pump start to run before the boiler even tries to burn gas. It's one of the many safety features.

Sign of the times Taf, everything should happen instantly or it's thought of as broken :D

Us old uns remember turning the TV or Radio on and waiting 5 minutes for the valves to warm up :LOL:

Am I the only person who thinks Mr K is an extremely unfunny miserable human?

Re: When does your Heating usually go on?
 

Yes :D

you think he's human:shrug:

There are plenty of other things I could have said but didn't want to get banned. :D

Re: When does your Heating usually go on?
 

Do you have the DT4 installer menu breakdown please? The gas man said they are programmed to work out the box. I'm just curious what everything does or means :)

Re: When does your Heating usually go on?
 

Our earliest valve TV had 2 switches: the first turned on the heating elements to warm the valves, the second, operated a couple of minutes later, turned on the HT (High Tension voltages). This was to prevent cathode-stripping which ruined thermionic valves very quickly.

As I joined the RAF, thermionic valves were starting to be replaced by discrete transistors. A few years later we were up to our eyes in Integrated Circuits and logic boards.

Wow! That takes me back to the RA17s we used at RAF Digby in the mid-70s…
