As I know that the rads used to heat a bit when the hot water was on (only hot water) I may still swap out the full valve and fully drain the system,, any inhibitors that you would recommend for my system & netaheat boilers?

Also, the water going into the expansion tank, if this continues after the thermostat change is there anything that this screams out as, as a fault?

What's the Heat exchanger made from?
If it's anything other than Aluminium I'd use Fernox.

As far as the Tank goes, check the level first. When it's cold it should have 4 or 5 " of water in it.

How old is this neataheat?
I remember one potterton did years back but there can;t be any of those left alive now!

Blimey, I’m not sure what it’s made of - I will try and find a model number and look it up.

The expansion tank ball cock works, it doesn’t look like any of th hot water goes into the overflow, it’s like it is taking the water it’s displacing

What speed is the pump on?

It’s alive!!

When I had a gas pipe removed last year they sniffer tested it and it’s emmisions were better than most combi’s apparently

They normally are just the permanent pilot and getting hold of spare parts that let old boilers down

That Boiler is the later version of the one I was thinking of. Pretty much the same thing, just the Gas controls that are a lot more modern on yours. The original Neataheat had all sorts on it.
Proper little gas chain. Automatic pilot too with a mercury vapour valve.

whats with the slap here message 😀

It was on 3, I have turned it down to 1

Well..... you know some people believe that you can fix things with a good slap....... when the boiler was playing up the pilot had gone out and wouldn’t fire up, my neighbour who has the same boiler had said something about a sticky valve, that is the area that you have to slap it apparently!

Auto pilot on these Shaun. The earlier model had one also. It worked in a similar way to how a Gas oven works. They had a Mercury vapour valve with a Phial over the pilot. Once it warmed up the Mercury would expand and open the Valve. There were separate solenoids and regulators on those too.
I'm reminiscing now !!
They were a nightmare lol!

Thank you, what about cleaning or is a flush through with fresh water a couple of times normally enough?

Was thinking about an old gloworm space saver

Ah!
Another amazing invention.
They would all outlast any modern effort!
