Thermal safety devices

Thermal protection for boilers and fireplaces – protection against overheating

Thermal protection for boilers and fireplaces with water jacket are key elements of a heating installation that protect the boiler from overheating and ensure safe operation of the entire system. The offer includes cooling coils and single-function and dual-function valves from brands Regulus, Caleffi, SYR and WATTS, adapted to boilers of various capacities.

Thermal protection allows cooling the boiler with cold water in case of boiler overheating (reaching temperatures above 90 degrees Celsius). A necessary solution when using a closed circuit for boilers without automatic fuel feed. A dual-function thermostatic valve with connectors as well as a single-function thermostatic valve with a cooling coil are solutions used in closed circuits of central heating installations, e.g. in the Czech Republic, in Germany, etc. An additional advantage is operation independent of the availability of power supply, as the device is activated thermostatically (e.g., power outage will not prevent the safety device from activating).

Thermal protection for boilers and fireplaces with water jackets – safety and stable operation of installations

Why is thermal protection necessary?

In boilers and fireplaces with water jackets, overheating can occur in the event of heat loss or system failure. Thermal protections:

• protect against excessive water temperature rise,

• increase user safety,

• prevent damage to the boiler and pipelines,

• ensure stable and efficient operation of the heating system.

Types of thermal protection

In the category, various solutions tailored to different types of boilers are available:

Cooling coils:

• WZS-2 – for boilers up to 35 kW (Regulus JBV),

• WZS-3 – for boilers from 35 kW to 90 kW (BVTS).

Dual-function cooling valves:

• Regulus DBV 1P,

• Regulus DBV2 – double protection for greater safety,

• CALEFFI with 1.3 m capillary,

• SYR 5067 with pressure reducer, in versions with 1.3 m and 5 m capillary.

Single-function cooling valves:

• REGULUS BVTS with 1.3 m or 4 m capillary,

• WATTS STS 20 up to 97°C.

Benefits of using thermal protection

• effective protection of the boiler against overheating,

• automatic response to temperature rise,

• compatibility with various types of boilers and fireplaces,

• easy installation in water jacket systems,

• long-term, trouble-free operation.

Application

Thermal protection is used in:

• solid fuel, pellet and wood boilers,

• fireplaces with water jackets,

• heating systems requiring automatic overheating protection,

• boiler room modernizations and protection of existing systems.

Summary

By choosing thermal protection for boilers and fireplaces with water jackets, you invest in safety, reliability and durability of your heating system. Properly selected coils and valves protect the system against overheating, increase boiler efficiency and ensure safe and peaceful operation for many years.
