Pictures are good, one would need to inspect and test, to ensure no faults, but most domestic alarms are not low voltage (230 volts) but extra low voltage (12 volts) and normally 4 wires used to each sensor, two to detect someone in the room and two anti-tamper, so it seems unlikely you have...

@stem has given you the answer, the wall thermostat stops the heating running when we have warm weather, it is doing that job it seems? My house, a little different as not a modulating boiler, but in most homes, the boiler produces hot water, which is pumped around the house, each radiator has...

What is required, and what is sensible, are not the same. BS 7671 is not law, but can be used in a court of law, so what BS 7671 says is not forcing you to do anything. And the changes are for installations designed after the date of the change, not existing installations. I, for one, have never...

First time I came across the diesel cab heater was 1980, seem to remember a Hunter make, fitted as standard to a Grove crane, mainly as too hard to get cooling water to the cab. The Eberspacher seemed to be the industrial standard, but Webasto is a close second, however there must be hundreds of...

I think one needed to reduce how many times the boiler is switched off, but to use modulating thermostats, not sure if they save enough to be worth the hassle? I have a few thermostats in parallel, so the boiler only turns off when no rooms need heating, and the TRV heads are analogue so most...

It does not matter what I think, SWMBO wants to use the liquid soap, and years of using power soap which stays in lumps, so ends up in the rinse water as well as the wash water I can see her point about trying to ensure all soap power is removed before rinsing starts. As you point out a new...

They do, not sure if I like the idea, and we no longer pay for the app. But my wife's Jaguar XE so about the smallest of the Jaguar range, could be started from the app, to warm up the car before you went out to it, but there was a warning it should not be used when parked on the public highway...

The flat rarely used in winter still has mechanical TRV heads, all fed from a motorised valve, so can turn the whole flat off. The main house has 10 programmable TRV heads, so every room has its own sequence, even with a 14 room house, the 20 kW boiler is twice the size required.

So I have heard it said many times, but my 18 kW boiler was too big for many shower heads, and I struggled to find one big enough. It is the lowest output which matters, my living room needs less than 3 kW, most other rooms a lot less, just enough to stop anything freezing, so the whole house...

Looked as if connecting 1 to earth which is why I questioned it.

It seems there is a change, in the main terminals 1 and 2 are not used. This however seems to show 1 and 2 is off the same as Wiser and Hive, so seems you have read the diagram wrong? And they are the same, it is the earth wire which seems wrong, can't work out why ever put there?

Yes, I feel sorry for ripped off customers, most it seems connected to government grants in some way. Be it solar panels, heat pumps, loft insulation, cavity wall insulation, the list goes on, and it seems to attract the substandard tradesman as people getting something for nothing or very...

I have never had the option of using OpenTherm, and I don't have a clue as to if links need removing or not, but would look for a post where the reply makes it clear they know you're using OpenTherm. When he replied, we did not know for sure you were using OpenTherm, I have quoted answer, so...

Since not finished December, yet that is incomplete, but it gives a good idea of solar production for a 6 kW array. ⁣ the best December day so far, ⁣ the best June day, this time of year the battery and off-peak are the main gain, the solar does very little, we are considering a third battery...

That does seem to vary with vehicles, my hybrid is so called as it can go on a road or in the field, all e-bikes require one to pedal, but is seems one does not need to have a direct link of pedals to wheels, but with other vehicles it means twin engined one electric and the other carbon based...
