Smart Consumption of Electricity

Intelligent consumption of electricity does not mean that you have to compromise on comfort. Instead, it means more effective consumption, comfort, and a smaller carbon footprint. By investing in the innovative Themo Smart Thermostat, you will ensure that your basic needs will be met using the minimum amount of non-renewable natural resources.


Intelligent In-house Assistant

Themo Smart Thermostat is an easy and useful assistant. Once you have configured the thermostat, it will function independently and free of interruptions. If you wish, you can adjust and control your heating with a mobile device and monitor the consumption of electricity by heating.

In addition, the LED indicator on the Themo Smart Thermostat shows you the price level of exchange electricity at each time. A green light shows you the best time to use household appliances that consume significant amounts of electricity.

Maximum Benefit from Exchange Electricity

Themo Smart Thermostat is best suited for optimizing the utilization and cost of exchange electricity. Themo Smart Thermostat optimizes electricity consumption by underfloor heating based on the market price and schedules the supply of power according to the most affordable and environmentally friendly times.

Greener Electricity

When the price of electricity is low, a larger share of it is produced without fossil energy sources. Themo Smart Thermostat will optimize the desired temperature based on your heating schedule, while simultaneously aiming to maximize the usage of more affordable, and thus greener electricity.

Without Sacrificing Safety

Themo Smart Thermostat is a safe product and service: the digital thermostats carry the CE marking, which signifies that they meet EU regulations, and all data pertaining to the devices, applications, and the portal designed for property companies is protected using SSL encryption.

Themo Smart Thermostat Pays for Itself

You can reduce your heating costs without feeling cold. In many homes, a significant portion of the electricity bill is comprised by underfloor heating in the bathroom. If the property is equipped with electric underfloor heating, Themo Smart Thermostats should be installed in each room with underfloor heating. Themo Smart Thermostats allow you to save both energy and money.

Themo Smart Thermostats can already be found in thousands of homes – make a smart decision to reduce your electricity bills and carbon footprint!

Reduce the Carbon Footprint of Your Household

For example, when Themo Smart Thermostat is used to heat a bathroom floor with an area of 5 m2, the reduction in the consumption of fossil fuels will correspond to approximately 126 kg of CO2 per year. If electric underfloor heating is the primary form of heating in your house, you can save hundreds of euros per year. Additionally, the reduction in the size of your carbon footprint will correspond to the emissions of a medium-sized station wagon, i.e., approximately 2 270 kg of CO2 per year. (Source: Traficom).

How many Themo Smart Thermostats will I need?

A Themo Smart Thermostat can be installed in each room with underfloor heating you want to control. If your home only has underfloor heating in the bathroom, a single Themo Smart Thermostat is enough. Correspondingly, you should also purchase a Themo Smart Thermostat for each room with ceiling heating.


Purchase Themo Smart Thermostats from Our Online Store

Purchase a Themo Smart Thermostat for each room with underfloor or ceiling heating. The more thermostats you purchase, the lower the price per unit.
