Watts Cazzaniga: Components for Thermal Power Plants and Safety

Safety First: Watts Groups

Problem: In a heating plant (boiler), uncontrolled increases in pressure or temperature can be dangerous. Furthermore, air in the system reduces efficiency and creates noise.

Solution: Watts' flagship product is the Safety Group (KSG Series) .
This compact device integrates three vital functions in a single block:
1. Safety Valve: Discharges water if pressure exceeds 3 bar.
2. Pressure gauge: To display pressure.
3. Automatic Air Release Valve: To release air.
Installing a Watts group means making the boiler compliant with regulations with a single reliable component.

Collectors and Floor Systems

Watts also specializes in distribution. Its stainless steel manifolds (HKV Series) are designed to last forever without corrosion. Equipped with flow meters for circuit balancing, they are the preferred choice for installers of radiant floor heating systems, ensuring precise room-by-room regulation.

Frequently Asked Questions about Watts Cazzaniga

1. Are Cazzaniga and Watts the same thing?

Yes. The historic Italian company "Cazzaniga" was acquired by the international group Watts Water Technologies. Today, the products retain the historic quality of the Cazzaniga design but are marketed under the Watts brand. Many product codes have remained unchanged to facilitate replacement.

2. How do I choose the safety valve: 3 bar or 6 bar?

It depends on the system. For domestic heating boilers , the standard is almost always 3 bar . For domestic hot water systems (boilers, water heaters), valves calibrated to 6, 7, or 8 bar are used. Always check the data plate on your heat generator before replacing the valve.

3. Are Watts electrothermal heads universal?

Watts heads (actuators) usually have an M30x1.5 threaded connection, which is the most common standard (compatible with Watts, Caleffi, Luxor manifolds, etc.). However, always check whether you need the 2-wire (standard) or 4-wire version (with auxiliary microswitch to start the pump).
