They look good, but still it needs to feed the info to a central smart control system.
The thing then is making it financially worthwhile. I could probably save money with a smarter heating system, but in my case I’m usually home, so many of the benefits are lessened.
My current system is actually very effective for us: we can choose several different temperatures over the day, and it keeps it very close to the target temperature (not within about 5 degrees like the old one). With family spread around the house, it’s near perfect for how we live. So while I do fancy the whole smart system, I don’t think it would actually make much of an improvement.
Our old thermostat was awful though - if the heating wasn’t on, you’d have to advance it about 5 degrees to click it on. It would then merrily heat the house to 25 degrees unless you had thought to reduce it.
The new thermostat measures to within half a degree (allegedly), and maintains a very steady temperature.
Er … I may be wrong, but aren’t the ladies correct ? The thing is that a rad stat isn’t like the wall stat which switches your boiler on and off. In the case of the wall stat the moment it switches on you get the boiler’s full power heating your home. So the place will warm up just as quickly as it can. But with a rad stat (at least the primitive non-intelligent ones) if you only rotate the setting a bit then it will only open the valve a bit and you’ll only get a trickle of extra hot water. So it will eventually end up at the few degrees higher temperature that you want, but it won’t get there quickly. If you want a quick but relatively small change then you have to open the rad stat fully and then shut it down to ‘open just far enough to maintain the temp’ when you get there. It’s exactly like the accelerator on your car. If you depress it very slightly then your speed will increase from 25mph to 30mph but it will take an age to get there. If you floor the pedal then you’ll be at 30mph in the blink of an eye at which point you need to wind your foot back.
With our rad stats on 3 they heat up quickly and keep the room at a decent temperature. Turn them to 5 the rads heat up quickly and then keep going until the stat turns off the boiler. Leaving them alone on 3 works just fine.
This is where hive and nest are a joy to use, no matter what twinkle thinks. Easy screen, changeable from your phone and much better for holidays and also my wife and I work from home 3 out of five days so the control is easy to keep the house at an exact temperature…
Yup Hive is brilliant, have it on two houses and one house has two zones (up and down)…
Meanwhile at the underfloor heated townhouse, which admittedly has 4 floors, four manifolds each with a pump, plus 2 pumps to circulate the water over the house, oh and the hot water system has its own pump (so you almost get instant hot water at any tap) (7in total!). … one of the pumps is playing up!
