james.wilson Posted April 6, 2020 Share Posted April 6, 2020 Following on from another thread. I use ifttt and my hkc 10270 with my drayton wiser heating system As it change the mode to away when fully armed i use a modified tr2 as my boiler is too old to support opentherm As the tr2 measures the (single room its located in) temp the boiler still modulates its power output rather than just on and off The wiser system then calls for heat by changing the boiler mode to 'comfort' from frost Plus im on LPG so any savings are magnified due to the fuel cost. Some rooms have more than 1 radiator. I prefer the accuracy of the room stats and will be getting at lease 1 more of these Quote securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

norman Posted April 6, 2020 Share Posted April 6, 2020 Looks good and I like the controlability of rooms independently, I currently just shut off any rooms we don't use (on this house we don't even have TRV's!) I will update to wireless ones when they are a bit more compact and the battery life gets better. My boiler is c20 years old but I'm not going to replace it until it fails, the roi isn't there for me so we still have the boiler and an immersion heater.

datadiffusion Posted April 6, 2020 Share Posted April 6, 2020 I guess OpenTherm wouldn't be compatible on a zoned system? I think our boiler might support it (well, it has a USB diagnostic port, I'm only going by 'if it's that modern' argument) but we have 3 zones hence 3 Nests and 3 zone valves (with rubber/flap type non-return on the Return part of the loop to prevent flowback) Which was interesting to have to do - and left me wondering how a 'proper' plumber would have stopped it? Most rads without stats in the same room have TRVs (apart from towel rails) As above I'm not sold on z-wave or other TRVs until the batteries last for years Quote So, I've decided to take my work back underground.... to stop it falling into the wrong hands Link to comment Share on other sites More sharing options...
james.wilson Posted April 6, 2020 Author Share Posted April 6, 2020 battery life im unsure of, but worst case ill change to 1.5v lithiums Opentherm does work on zones, i run my zones as rooms you can add upto 8 (iirc) trvs per room so opentherm would call for heat output from the boiler based on heat required for the rooms calling for it etc. Nest wouldnt work for me which is why i went for the drayton. The trv's arnt mesh so require powered boosters if range is an issue but in my old cottage I didnt need any Quote securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

I got rid of all my Lightwave TRVs for that one reason, I got fed up replacing the bats, programming the day and date and relearning them. I have non powered TRV's now. I will wait and see how James gets on with his and I may buy a few for areas where I think they would be useful leaving manual ones in the rooms I rarely use Quote Link to comment Share on other sites More sharing options...

For most it's going to a low cost, mate of mate job with eBay / amazon kit. Rather than control4 in a footballers mansion ? Much like cctv, many domestic jobs think it's gonna be a £100 dearer than them buying the kit... Err running vans & men + buying stuff that's a bit dearer than swan make a job a grand when the sub was thinking £500 1 Quote Mr Veritas God Link to comment Share on other sites More sharing options...
