I have Gas CH with a programmable Honeywell Thermostat & TRV' s on the radiators (except for the heated towel rail)
the Honeywell Thermostat is having a well known problem with its digital display screen. There's a known work around which I've been doing for a few winters, but it's getting less effective each time & needs to be done more & more frequently. It involves very fiddly circuit boards & heating them up & I just can't be arsed doing this all the bloody time.
the cheapest/ easiest thing is probably to buy a replacement Honeywell thermostat that's a newer version of my model - & hopefully it'll just connect itself with the bit in the boiler, but no guarantees.
However, one annoyance I've had over the years is that I can't have the heated towel rail on, when the other rads are off unless I manually turn each TRV's off ( and it's just too much a faff to do that every night & on again every morning!
( I want to do this as i don't like the heating on everywhere in the mornings, but I would like to take the chill off the bathroom)
i don't want to retrofit an electrical heating thing into the HTR either. It would mean removing tiling to get an electrical supply and they don't make the tiles anymore & I really like them.
so I think the only way to achieve that is a hive/Tado system. I had considered doing a Tado replacement myself (I've done lots of things myself) but I think it's a bit beyond me these days. (Brain Fog, physical limitations due to an accident, balance/BPPV issues) so I'm thinking I might need to have it done.
Anyone have any advice/opinions/idea of cost etc??
