No problem!

We get a lot of questions about tado in combination with underfloor heating. We will briefly explain them here and give you a correct and hopefully clear answer. The questions often arise from the following two causes:

  1. There are many stories going around on the internet that tado would not work well with underfloor heating.
  2. I have a tado set with smart radiator controls and now my underfloor heating is no longer working properly or is even going crazy!

Tado doesn't work well with underfloor heating

Let's get straight to the point and disprove this statement right away: tado works great with underfloor heating! Provided it is installed correctly.

There are a number of things we come across that probably caused these stories.

Tado is still quite young (2011) compared to Honeywell, for example. In the beginning, tado did not work well with underfloor heating, but this was solved years ago and now works fine, so perhaps these stories will stick.

In addition, we often see that the underfloor heating is not connected to the system correctly or not at all (see also point 2). Then it really doesn't work. A handy harry who "thinks" he knows, but also does something, often causes problems and unnecessary costs afterwards. So always make sure that you have this done by a recognized company (with experience), we at Savvycons have been working (together) with tado since 2011 and are the recommended installer for the Netherlands

An example is that a smart radiator knob is often used for the underfloor heating, of course this is not possible, it is called for a reason radiatorknob.

I have a tado set with radiator controls and now my underfloor heating no longer works!

To understand why this is the case, we compare a common old and new situation with underfloor heating on the ground floor and 4 rooms with radiators on the first floor.

  old new
System 1 central thermostat

1 smart thermostat in the living room
4 smart radiator controls

Who can ask for heat, or who can turn on the boiler? central thermostat

the smart thermostat and the 4 smart radiator controls

What happens when you turn a radiator knob? your radiator opens and heats up as soon as the central thermostat in the living room asks for heat

your radiator opens and controls the boiler on so it gets warm

When does the underfloor heating get hot? when the central thermostat calls for heat

if the smart thermostat calls for heat, but also if your smart radiator valves ask for heat

 

As you can see, the new situation ensures that the underfloor heating is unsolicited, so for example if it is already warm enough in the living room, the moment a smart button asks for heat.

To prevent this, a valve must be installed that ensures that your underfloor heating active is controlled by tado rather than passively. In other words, tado can determine whether or not your underfloor heating gets heat by opening or closing a valve, just like the radiators you open or close. We hope this makes sense after reading this story. If you still have questions, don't hesitate to ask.

The solution

For the most common situation, your underfloor heating as 1 zone, we have a complete solution in our webshop. This exists in 2 variants:

Option 2

If it is possible to connect your smart thermostat from the place where your smart thermostat will be installed (in the room with underfloor heating), it can be wired to the underfloor heating distributor. 

This set contains:

  • tado wireless receiver (to control your boiler)
  • a valve for your underfloor heating
  • Installation service, everything is installed and connected
  • the necessary small equipment such as some central heating material and cables.

 

Option 3

If it is not possible to connect the thermostat by wire, you will need this set.

This set contains:

  • tado wireless receiver (if you don't already have one)
  • a valve for your underfloor heating
  • an extra thermostat to control your underfloor heating valve, this will be mounted at the distributor, but it does not measure the temperature here, that is what the other (current) thermostat is for. 
  • Installation service, everything is installed and connected
  • the necessary small equipment such as some central heating material and cables.

 

In addition, you can also use tado je floor heating in several zones However, this involves a bit more and we have to zoom in more specifically on each situation. Take a moment for this contact Contact us to discuss the options for your situation.
