1.2.24 Installation of thermostatic radiator valves
Description
These elements open and close automatically the flow of hot water in radiators and fancoils, depending on the temperature selected by the user. To install thermostatic valves, the heating circuit should be leaked out and the shut-off valve should be replaced by a thermostatic valve.
Benefits
High energy saving depending on the building and the zoning of the distribution loops (between 5-7% of the heating generation energy)
Adjustment room by room, according to their characteristics of temperature, insolation and use
In buildings where only some areas are used after normal schedule, the installation of remote control thermostatic valves allows heating out of the schedule only the required areas
Limitations
Incorrect handling by users
Occupant acceptance
Economic assessment
Initial investment: low. Measure of easy implementation (20€/valve).
Payback: Between 1 and 2 years.
