Protection and regulation of solid fuel boilers

What are thermostatic valves and how do they work?

Thermostatic valves that work without any outer actuator, just on the water temperature, represent a simple and reliable method of protection and control of solid fuel boilers.

Recooling valves

Recooling valves prevent boiler overheating in case of a power breakdown or heating system pump failure.

Mixing valves

Mixing valves keep the return water temperature above the flue gas water vapor condensation point, protecting the boiler’s heat transfer surfaces from corrosion and clogging.

Animated diagrams, explicitly showing how heating systems with and without thermostatic mixing valves work, can be viewed here.

Thermostatic Pump Stations

Pump stations with thermostatic mixing valves fulfill the same boiler protection function as TSV valves, making the installation even easier because they are fitted also with boiler circulation pumps, possibly also heating circuit pumps and other components.

Regulus CS Pump Stations

Regulus CS Pump Stations make boiler installation easier. They contain all the important components necessary for boiler protection and proper operation in both space and water heating. They are designed to be mounted directly on a boiler flow pipe or on a wall.

Draft regulators

Draft regulator controls the combustion air inlet damper, i.e. it also keeps the heating water temperature at the preset value, helping in cost efficient boiler operation.

Backup sources

UPS units for solid fuel boilers prevent boiler overheating in case of a power breakdown. Using a 44 Ah accumulator, a Wilo 25/4 circulation pump can be kept running for at least 5 hours.
