Worcester Greenstar 30Si Compact ErP with no thermostat receiver but with thermostat

[fixitflav]

I am guessing someone to hard wire the receiver into my boiler and then replace then install the thermostat with batts installed. Any idea on UK cost?

If it's hard wired the boiler doesn't need anything which I'd describe as a receiver. When the thermostat sends 240 volt to the boiler, it fires!
What do you think Hive will do that the Salus can't, except maybe (guessing now) remote access via a smartphone?

As a matter of interest, do boilers ever have built in receivers? Putting them inside a Faraday cage doesn't sound like a sensible idea to me.

Yes

try a quick google!

Coincidentally, try a Salus for starters:

Fair point. But are you saying that this is fitted inside a boiler? The instructions don't mention that. I suppose there is no reason that they couldn't allow for aerials if the receiver is integral, but everything I've looked at on the internet is rather vague on that detail.

It would normally replace the round timer/clock on the front panel...

For another example, modern WB have an "RF Key" module, that slots into the bottom of their boilers...

No external antenna are used.

You have a wired stat not an RF one easiest to replace is a NestE it is also battery powered , the two existing wires go into the nestE Com and NO terminals doesnt matter which way round, dont get another model of Nest or hive they wont work without wiring alterations

And top your boiler pressure up before the boiler stops working

also_

1) top pressure up to 1bar
2) Turn heating dial to e or lower.
3) turn hot water temp down as well.

OK, batteries have been out for an hour now and thermostat display has went off. Does this mean that this is not hardwired to the thermostat after all?

No, it just means the internal backup battery has run-down.
Your thermostat is battery powered (not mains powered), even if it is hardwired to the boiler.
The display showing, without the batteries, was never an indicator of whether it is hardwired.

Remove the thermostat from the wall - and see what connections are behind it...

This is the thermostat I have.

Yes, It looks like it...
But so do other models...

Here is the RT510, a battery operated, hardwired thermostat...
