Base for appropriate boiler selection is a thermal balance of the heated area created according to thermal standards for buildings. While selecting boiler for heating multi buildings systems it is recommended to calculate thermal balance. During calculation it is also important to take into account heat loss in the transmission system of the building. To select the most appropriate boiler for you please use our Assistant. In the chart below is technical data, which can be used for selection of appropriate size of the boiler. The given data is approximate and was estimated for rooms up to 3m height and heat loss of 110W/m2.Before making the final decision please remember to take into account 10% of boiler’s power reserve in proportion to actual power requirement resulting from thermal balance calculation.
