What indirect heating boiler to buy

When choosing a boiler plant, the calculation is performed - the number of people and water points, as well as the consumption rate is taken into account. When purchasing a storage tank for its own needs, the necessary parameters are determined more precisely - experimentally. Before purchasing, many parameters of the device are taken into account, the main ones being: power consumption, storage tank capacity, system pressure, operating temperature.

1. For a small dwelling with the number of people living in 1, 2 people, Gorenje GV 100 will be enough.

2. For 2, 3 family members living in a 1-storey cottage with an attic, Baxi Premier plus 150 will do.

3. In a 2-storey house with 3, 4 tenants, it is advisable to install Drazice OKC 200 NTRR.
