This work contains the calculation and a list of chosen heating equipment designed for a residential building in Crikvenica. The residential building is made of a ground floor and a first floor and its total size is 175,4 square meters. Wall, ground and roof layers needed to be designed, as well as the rate of thermal transmittance calculated. C is the mark of the energetic efficiency of the residential building. It has been calculated on the basis of estimations of benchmarks. There are no extremely cold winters in Crikvenica and that is an extenuating circumstance. However, in order to reduce thermal losses i.e. increase the level of energetic efficiency, the residential building needs to be additionally isolated and that increases building costs. According to the calculations of the total thermal losses, the chosen central heating system is a pellet stove, power of 19 kW. The stove is connected to the heating bodies by the conduit and crossbars, expansion tank, circulator pump, consumable hot water tank and various faucets. The heating bodies are sectional radiators that are placed in the rooms of the residential building, as well as bathroom radiators placed in the bathrooms. The expansion tank is chosen bearing in mind the calculations and its main purpose is to maintain the pressure of the heating medium, as well as to control water loss. The circulator pump was also chosen due to the calculations and its purpose is to lead hot water to a certain place in a closed circulator system. The same rationale was used to choose the consumable hot water tank which serves to heat up drinkable water that members of the household use.
