TERMOVAR LU (EN) 06.12 GENERALLY TERMOVAR is an automatic loading unit for sold-fuel boiler/storage tank installations. The loading unit ensures a minimum return-water temperature into the heating boiler, which encreases the boiler efficency, prevents tarring and considerably prolongs the lifetime of the heating boiler. TERMOVAR eliminates the risk of destructive thermal shock caused by surges of cold return water and renders a more effective burning. - Page 3 TERMOVAR LU (EN) 06.12 MOUNTING The valve unit is mounted upright either on the right or left hand side of the heating boiler. After pipework the thermometers are pressed onto the front side of the unit. When starting a new heating installation a very common problem is air in the pipe system. For a trouble free system the pipework has to be made without air pockets.
- Page 4 TERMOVAR LU (EN) 06.12 2. Loading phase The thermostic element in the loading unit is affected by the temperature of the water flowing from the boiler to the loading unit. The element starts to open and allows return water from the storage tank to be mixed with supply water before it returns back to the boiler.
