Residential renovation in Prague
Smart control that makes residential heating more efficient and affordable.
Introduction
Located in Prague’s Kusého district, a residential block of 72 flats underwent a major hydronic renovation to improve comfort and energy efficiency.
The eight-storey building was previously connected to district heating but suffered from high supply temperatures, imbalance, and wasted energy. With sustainability goals and compliance to Czech energy efficiency regulations, the owners sought a modern solution that would stabilise consumption and reduce costs.
The Hydronic Challenge
The system was unbalanced, with excessive supply temperature and flow from the district heating network, leading to significant energy waste. Residents experienced uneven heating and high costs, while the building’s operators faced difficulties in managing flow rates and ensuring compliance with Czech law nr. 406/2000 and nr. 193/2007.
Solution
IMI introduced a complete hydronic solution, combining automatic balancing and smart control technology:
- 297 TRV Eclipse thermostatic valves for room-level comfort and energy efficiency
- STAD, STAP, and STAF balancing valves for stable system hydraulics
- TA-Smart DN50 as the main control valve in the mixing station, equipped with power limitation in line with the contract with the district heating provider
- K-head thermostatic controls for user-friendly adjustment
The TA-Smart valve plays a central role, regulating maximum agreed power (Pmax), providing full hydronic balancing, and ensuring pressure difference control. Connected to HyCloud, TA-Smart monitors flow, power, and temperature differentials, while storing data for further evaluation and potential optimisation of contractual power limits in future years.
Customer Value*
The renovation delivered measurable results:
- Energy savings of 22,715 kWh/year
- 9.3% reduction in energy consumption
- Annual financial savings of approximately 3,166 GBP
- Improved comfort for residents with stable heating conditions
- Data-driven optimisation possibilities through HyCloud monitoring
