IMMERSIBLE MECHANICAL THERMOSTAT (Standard on SFL):

The thermostat is suitable for operation with wood and coke. The central heating water temperature is maintained at the desired value by automatically adjusting the combustion air intake through a simple yet effective system. The thermostat will reduce the air intake as the temperature rises and activate the air diaphragm as the temperature drops, to refuel the flame. This system optimizes combustion quality by reducing soot and fuel consumption.

COIL AND THERMOSTATIC VALVE AGAINST OVERHEATING: (not included in the price)

The installation of this device is optional according to the EN 303-5 directive. It consists of a thermostatic valve and a coil. The coil is a heat exchanger with dimensions suitable for the model size, so it is immersed in the boiler's heating water. The thermostatic valve detects the boiler temperature through a dual-sensor detector. If the boiler temperature reaches 95°C, the valve releases the excess heat which is exchanged in the coil.
