You'll never measure the speed of light with that...

Any good? How easy are they to install?

EDIT: Just seen your later post!

Is it all controlled by the app or do you have manual control as well?

Alexa?

Main control (ie set up) is from app. Schedules etc.
But if you want to override you can use Google/alexa. Or just turn the physical valve head. That will override the current schedule

If you can, try and get Danfoss’ pressure independent control valves and get gas heads. The PITRVs are more accurate and will regulate both pressure and temperature, and gas heads react much quicker to changing temperatures than liquid or wax.

Also, return temperature limited on any towel rails is great.

Forgive me as I'm a bit dense, but does it really make that big a difference by having different types of TRVs? I had a brief look at danfoss ones and they seem quite expensive.

Wehn you say "return temperature limited on any towel rails is great." What does that mean? I thought towel rails are the only ones you're not supposed to put TRVs on so that the heat can escape somewhere?

Regardless, just spent ~£500 on a tado (theromstat+Hot water & 10 valves). @413x I'll blame you if I wire it wrong :cry:

That's quite alright, I don't know loads about it. Basically, TRVs without pressure control allow flow rates to fluctuate quite a bit within the radiator. Without pressure control, you can balance your radiators as much as you like, but if you end up changing the setting on one, my understanding is that the flow of that radiator will be distributed amongst the other radiators, making it relatively pointless balancing them in the first place. You'll then end up using more heating/hot water than you need to making your system less efficient.

Towel rails are generally terrible. So you have a radiator that you immediately cover in insulation (towels) and put that in your system, meaning that it can't give off any heat. What's the point? The water will enter the radiator at around 70C and leave at roughly the same temperature, so it hasn't really used any of the heat you put into it. If you use a return temperature limiter, you can force the flow rate to slow dramatically such that you actually use the heat you're pushing through it.

Most people don't do this, no. But if you're willing to spend £500 on heads you may as well make sure the rest of it works well!!

PS. getting a low return temperature is what you should aim for as it means the heat you have in the system is actually being used.
