As long as the boiler model is correct, you have taken out the 24v RT link and you have a single channel Hive then yes; it is technically correct. The simple test is, does it work?

Just an idea as I don’t quite understand what it is that’s not working, but you have set the radiator temperature on the boiler to 65/70ish? If set too low, the Nest will “call” for heat but the boiler will just sit there staring at you.

Personally I prefer to core outside to inside because of the mess and dust. Depending on the wall type and the finish required, if needed I will pilot all the way through, do 90% of the core from the outside and then finish the core from the inside to get a good finish. However this takes some...

1 goes to 1 for hot water off ;)

So if this is the single channel version as you had a programmable thermostat, you would normally mount the Hive Receiver next to the boiler as it will need a Live, Neutral and Switched output cable at minimum. The actual Hive Thermostat will then go in a suitable location like the old...

Sorry. You are looking at the wrong wiring. The Hive Receiver replaces your clock ;) You will then need to link out and make safe the thermostat wires so the thermostat is effectively always on. Additionally, you didn’t mention what Hive Receiver it is you are trying to fit. The single or...

I presume you mean the T3R... Nest (Plus stand) and Hive can replace the T3R, you simply bin the T3R (and Wireless Receiver) or fleabay it.

Sorry, that’s a case off job. Give your local RGI a call, shouldn’t be too difficult for them to resolve but not likely to fix itself.

You have had everything replaced but they left you with no additional controls? Part L of the building regs advises this should be converted to a fully pumped system when appropriate - A cylinder change IMO is the right time to convert to fully pumped. As for the heating on upstairs - Do you...

The 5Ghz channel has more bandwidth which means it can transfer more data at once. It will be faster than the 2.4Ghz. However due to the size of the wavelength it gets cut easier by your home’s construction and does not travel as far.

A lot of RGIs carry the G3 unvented qualification. Many will also register their qualification with Gas Safe and you will see “Unvented Hot Water Storage Cylinders” ticked on the qualification list on the company/engineer verification screen. As for what it involves, this depends on the...

PN = Pressure rating DN = Diameter Then usually a BS or EN describing the bolt patten. http://www.fwb.co.uk/files/ww/fwb%20Flange%20Tables%20and%20Gasket%20Materials.pdf

Fan on most boilers form part of the combustion system, irrelevant of where it sits. Part of a fan exchange should include a couple of other tests ;)

G3 qualified is the ability to work on unvented cylinders. This does not apply to combis only mains pressure hot water storage cylinders. As for gas regs, you can work on your own boiler without gas safe registration as long as you are “competent” to do so. This has always been the case. The...

Odd bit, nothing major and all iron based, pump housings, pcb housings and general odds and sods. There would have been bits of cable and maybe the odd zone valve. Just annoyed that this has happened twice now. I’ll have to look into this alternate collection companies. £60!!! Wow. I just...

You will need a Natural Gas BBQ if you want to run it from the metered gas supply. Check gas safe register for local engineers with “Leisure” appliances on their ticket. They will be able to advise further.

https://www.myson.co.uk/static_files/my/media/downloads/MEP1c_User_Guide_(rev6).pdf The MEP1c is a single channel controller... It can do heating OR hot water... What boiler do you have? You sure you do not have any other controllers?

We are refurbishing the house at the moment, the gated drive is on the hitlist - Along with a million other things, just seems crazy that I have to pay to protect rubbish (Literally rubbish!). How do trades that live in flats or with no outside space do this? I heard NHDC was going to trial...
