Is tado° compatible with my heat pump?

The Heat Pump Optimiser X is compatible with air-to-water, water-to-water and brine-to-water heat pumps, even when not connected to a thermostat.

What if my heat pump is not listed as a compatible model?

tado° is continuously growing the compatibility of the Heat Pump Optimiser X. Tell us which model you have at home and we'll get back to you as soon as tado° is compatible.

Can I install tado° on my own?

Easy at-home install - tado° app guides you step by step and is customised to your heat pump. You may have to open your heat pump, but don't worry: tado° will help you every step of the way.

How does the Heat Pump Optimizer X help me save energy?

By controlling your temperature and schedules in the app, you can make your heat pump's energy consumption even more efficient. This means it consumes less energy.

Does the Heat Pump Optimiser X replace my heat pump programmer?

The Heat Pump Optimizer X does not replace the heat pump programmer, it synchronises with it. You can still decide whether you want to control your heat pump using tado° or the heat pump itself.

My heat pump already has its own app. Why do I need the tado° app?

With the tado° app, you control the schedules of your temperature and your hot water. You also get custom insights into your energy consumption. With the tado° app, you have more options to improve your energy use. Plus tado° Balance, which allows you to use your time-dynamic tariff with your heat pump.

What is a time dynamic energy tariff?

A dynamic hourly tariff is an electricity tariff where prices change every hour based on wholesale electricity prices. As a user, you can save more by moving your energy use to times when electricity costs less.

By subscribing to tado° Balance, you also enable your heat pump to benefit from these tariffs and save even more energy costs.

I do not have a time dynamic energy tariff. Can I still use tado° Balance?

You can use Balance if you want to make sure that you use as much green energy as possible and that your heat pump control considers the outside climate.
However, to utilise the full energy-saving potential of your heat pump, you need a time dynamic tariff.

How much does Balance cost?

You can book Balance in the app for €5.99 per month or €49.99 per year.

I'm buying tado° for the first time. Do I need a Bridge X?

The Heat Pump Optimiser X also works as a Thread Border Router. This means it connects your smart home network to the internet and the tado° cloud. So you don't need an additional tado° Bridge X.

I already have tado° V3+ with an Internet Bridge. Is this compatible with tado° X?

If you already have tado° V3+ devices in your home, simply expand them as before with the V3+ Add-ons. The Bridge X and all tado° X products are not compatible with tado° V3+.

Can I control tado° using my smart assistant?

You can control all tado° devices easily using Alexa, Google Assistant and Apple Home.

Can I return tado°?

Yes, you have a 14-day right of return following your purchase. In addition, we offer our Money-Back Guarantee, which allows you to return tado° X within the first year if you’re unhappy with the results.

What happens if I’m offline?

Your heat pump's programming settings are automatically saved so it continues to run even if the internet connection fails.

What's Matter?

Matter ensures a simplified connection between tado° and your smart home, regardless of which products or brands you’re using. Matter-enabled devices will work together reliably and securely now and moving forward into the future.

What's Thread?

Thread technology was developed to make networking smart home devices easier: Thread-enabled devices form their own, robust network so that they communicate with each other. The entire network only requires one Thread border router, regardless of the devices you have and the manufacturers they’re from.
