I had a massive problem, there was a likelihood of the cistern falling through the floor, the shower tray was leaking, the beam under it had rotted away, and I managed to get a plumber and chippy who worked together to repair it.
There was also in comparison a minor problem, there was no or little control of the central heating and domestic hot water, and the plumber got all the parts required, but was to return to do central heating as that was not emergency work, plus it allowed me to prepare for it.
So I was left with two motorised valves, a by-pass valve and 14 Tower TRV2 radiator valves, so I have fitted Nest Gen 3 and two wiring centres and the motorised valves are now wired in ready.
I already had 4 MiHome Energenie TRV heads and has added a further 5 Eqva Bluetooth Sma heads, however the plumber has put his back out, so it seems it will be some time before he returns.
The original TRV Mistral 1 were mounted horizontal, and in many cases on the return, and I know from bitter experience the MiHome heads work better on the feed, also the Eqva Bluetooth Sma heads are hard to read when mounted horizontal and in some locations the radiator does not have enough room for the longer electronic heads to fit.
So may be good reason to swap the lot, however I wonder what goes wrong the TRV bases and do they really all need changing? Thinking he may not return before winter, so do I really need them all changing?
Also I was leaving the 4 TRV's in the flat with non electronic heads, flat is not used much, so what makes a good head, and what is rubbish? The new ones say liquid sensor, I want a back ground heat in the flat to stop freezing, not sure if the TRV really has much work to do down there, as wall thermostat will most of time be turned to anti-frost only.
I can't work out why mechanical TRV heads are so expensive, in some cases more expensive than electronic, to me it seems a head which can have day and night setting must be better than one where you have to physically turn it up and down day and night, and a display in deg C is better than 1 to 5.
But if it was that simple, there would be no mechanical type sold, so there must be more to it, but what?
