fixed : Smart Thermostat is too large for the space I have next to my radiator

Question :

I want to install Smart Thermostats on all my radiators, but some of our radiators are in a cove where I a regular smart Thermostat won’t fit because it’s too bulky. There just isn’t enough space to screw the Smart Thermostat onto the radiator valve, there’s only 78mm of space.

What options do I have ?

 

Answer :

Most Smart Thermostats are bulky because you need to install 2 AA penlite batteries inside the Smart Thermostat. The TP-Link KE-100 Kasa Smart Thermostat is 88mm in length and even the Tado Smart Thermostat is 80mm in length. So, even if your radiator valve is M30x1.5 the space you have is too small… so, you only have 2 options :

(1) the Fibaro “The Heat Controller” FGT-001 which is only 75mm in length, because it isn’t powered by AA penlite batteries, but by a built-in rechargeable battery that can be charged through a mini-USB cable

Note #1 : the Fibaro FGT-001 comes in 2 versions : an Apple HomeKit-compatible version and a non-HomeKit-compatible Z-Wave version that is compatible with Google Home and Amazon Alexa

Note #2 : the Fibaro FGT-001 (HomeKit version) is rather easy to install and program, but the Fibaro FGT-001 (Z-Wave version) is slightly more difficult to install end harder to program, and you will also need a Z-Wave Hub (a.k.a. “Z-Wave Controller”) but it’s extremely programmable

(2) use a perpendicular M30x1.5 angle adapter to get your Smart Thermostat pointing in a more convenient direction, like this one :

That’s it – you choose 😉

fixed : adapter for Smart Thermostat on slightly smaller Comap radiator valve

Question :

I want to install Smart Thermostat knobs onto my radiators, and on most of my radiator valves I succeed without problems, even without adapters, but on some the thread just won’t fit, even with the adapters that are included with the Smart Thermostat. These radiator valves seem to have a slightly smaller thread and the original head is branded “Comap”. Still, I can’t find adapters for “Comap” anywhere…

Which adapter do I need ?

Answer :

Most Smart Thermostats can be screwed onto any M30x1.5 radiator valve (which is sort-of the standard these days) and most Smart Thermostats come with some adapters (usually for RA, RAV and RAVL valves) but the “Comap” head you are talking about is a M28x1.5 (usually referred to as a “Heart” (or “Herz” in German) valve.

So all you need to do is find the right adapter. For your “Comap” valve that is a M28x1.5-to-M30x1.5 adapter. All Tado Smart Thermostats do have this adapter included, but if your Smart Thermostat is from a different brand, you will need an adapter like this one :

Heimeier / Herz adapter (buy it on Amazon)

That’s it !
