Reduce the Cost of Underfloor Heating in Rental Apartments by Up to 50%


Property companies that manage rental and right-of-occupancy apartments can achieve significant savings by controlling the underfloor heating in bathrooms and other areas in a centralized manner using smart optimization.

Themo Energy Saving Service for Rental Properties

In particular, underfloor heating in bathrooms can account for a significant portion of the electricity consumed by rental properties. When residents are not responsible for the electricity bill resulting from the use of underfloor heating, they may not pay attention to the level of heating. Excessive underfloor heating may even have a detrimental impact on the district heating system.

The Themo Energy Saving Service controls the apartment-specific underfloor heating in a centralized manner. The service is based on smart thermostats that are installed and maintained by Themo, and the regular monitoring of their functioning. The person in charge of the property maintenance can remotely control and monitor underfloor heating in each apartment at their discretion using the convenient portal.


Increase the Cost-effectiveness of Rental Activities

Centralized optimization of electricity consumption by underfloor heating is an effective way to reduce heating costs and the carbon footprint of heating, without affecting living comfort. Themo Energy Saving Service ensures even temperatures and precise adjustability in all rooms with underfloor heating.

Themo's smart algorithm optimizes the heating apartment-specifically by taking into account the actual heating requirements and the elasticity of demand impacting electricity prices. If the apartment is unoccupied, the underfloor heating can be set to a minimum level that is suitable in terms of property maintenance.


Themo offers a solution to a significant problem. Themo Energy Saving Service enables us to control each area with underfloor heating separately at our discretion. This eliminates excessive heating and also allows us to ensure that underfloor heating is activated in each bathroom in the first place. A brilliant service and an excellent tool.
