If you are installing a La Nordica Thermo appliance (boiler cooker or boiler stove) onto a closed expansion tank / sealed system then you will need to fit a temperature relief valve.
The DSA system was designed by La Nordica to be an automatic safety device which quickly reduces the water temperature in the boiler in a sealed hot water system should it overheat. This is in compliance with current European regulations and standards (2019.)
The system comprises of a ‘heat discharge coil that is inside the boiler and a temperature actuated valve that connects to the water supply. The valve is usually closed but once it has been activated (i.e the water has reached the preset temperature 95°C) the DSA valve will open and cold water will flow through the heat discharge coil to bring the boiler’s water temperature down.
The valve that we supply will work with all La Nordica Thermo products.
