Someone mention a nip......

Here's one on me ---- :p

Have discovered that when set to HW only, we have no hot water. :mad: (One gate valve on the bit of pipe that goes into the tank and presumably lets hot water from the boiler flow in or out of it, is probably jammed closed. I can only get it to move slightly in either direction, I must have closed it, in error, when trying to isolate the hot water system. )

So for the moment ignoring that and concentrating on what I hope is purely a, or more than one, airlock.
They are quite common, I have had one at least before and a heating engineer who was a member of my car club told me how to fix it.

I did check it out on tinternet just to make sure I wasn't yet again doing something stupid and yes, they are quite common.
so all rads closed now except for the one in the main bedroom, obvs have bled them all and none had any air. Waiting to see how hot it gets.

As for the hob. We were cooking dins together. She did chips in the oven in said oven pan. I boiled up some grren beans for myself.
The meat tin once empty must have been put on the ring.
She says by me, I say by her, .....

Anyway, it took effort but is clean as a new pin now.

See yez!
Don't understand your CH/DHW issues at all. The systems are so simple. Just motorised valves and the like, and you can manually override them to check if its the control motor or the valve. I know/knew naff all about CH 34 years ago, but I put this system in and it is still going strong. The recent 18 months ago TRV on every rad threw the only "wobbler" in all that 34 year period of time as I had no heat sink because the bathroom(s) rads were shutting themselves off.
 
Had a useful e-mail exchange with those lovely Octonauts at Octopus Energy today.
They confirmed that IF an Air Source Heat Pump worked at maximum efficiency at castle clarke it would still (like for like) cost me more to use ASHP for heating than using my current inefficient 34 year old gas boiler. Not by a lot, but it would still be more costly.

Right.
The HW issue is sorted. One closed gate valve which is now open.
I have precisely one motorised valve that's all.
But, like you I am mystified as working on all the central heating systems, gas boiler driven, that I have had in 4 houses, I have never had a problem like this.
I have had one airlocked rad once up until now.
I thought I was getting on top of it before dinner, but while we were eating it went back to square one.
I nearly had nearly all the rads working.
I think I tried to go too fast, getting one rad working, then another, then another..... I had all 3 on the top floor working, then carried on downstairs, got one working, then tried to get another on stream..... That's where it went wrong.
I'll be back on it tomorrow, taking more time and after having done more research. It is only a 7 rad system now as the other 7 have all been closed off for ages.
I just wish I could visualize it and see how the airlock or airlocks developed in the first place, then I might be able to solve it.
