Why install convertible valves and thermostatic control heads

Room-by-room temperature control is no longer just an option: it’s essential for anyone aiming to improve indoor comfort while reducing energy use.

Convertible valves and thermostatic control heads offer an efficient, accessible, and technically reliable way to manage heating independently in each room, even in existing buildings.

How thermostatic control works

The convertible valves regulate the flow of hot water through a radiator.
The thermostatic head, which is sensitive to room temperature, adjusts the valve’s opening to maintain the desired heat level.

The operating principle is simple:

• When the room temperature exceeds the set value, the valve closes partially or fully, reducing the flow of hot water.
• When the temperature drops below the set point, the valve opens, increasing the flow and the heat output.

This automatic modulation helps avoid energy waste and temperature fluctuations.

Key benefits of a system with convertible valves and thermostatic control heads

1. Flexible installation
Suitable for both new and existing buildings, easy to install with no major structural work required.

2. Room-by-room comfort
Each space has different needs (bedroom, living room, bathroom): independent control lets you tailor the temperature to the function of each room.

3. Simple and essential
All you need is one convertible valve and one thermostatic control head per radiator for precise local control.

Itap products for thermostatic regulation

Our catalog includes a full range of valves compatible with the 891R thermostatic control head. In particular:

• C and V families – ideal for direct mounting on radiators, allow for independent room control.
• CPS family (with presetting) – enables you to limit the maximum flow to each radiator, optimizing overall system efficiency.

All our products are made to high quality standards to ensure long-term reliability and durability.

Best practices for proper use

• Avoid placing the thermostatic control head in niches, behind curtains, or in direct sunlight.
  
• Lower the temperature at night or in rarely used rooms.
  
• Air out rooms briefly to minimize heat loss.
• Always rely on a qualified technician for installation and setup.

FAQ

What are convertible valves?

Devices that automatically regulate the flow of hot water into radiators based on the ambient temperature setting.

How do thermostatic control heads work?

The head contains a temperature-sensitive bulb that opens or closes the valve to modulate heat output.

Can they be installed on existing systems?

Yes. Thermostatic heads and valves can be installed on pre-existing systems without major modifications.
