Plant for a House Heating
When the wood burner (6) is working, the produced heat will be transferred to the storage tank (3) or, if necessary, warm up the water in the hot water deposit (2).
When the solar collectors (1) produce heat, the solar liquid will bring it with priority to the hot water deposit (2). From the storage tank (3) the heating medium will be pumped through the radiators (5) to distribute the heat in the house.
If the requested temperature is reached, the change-over valve (4) will conduct the heat to the storage tank (3).
There are some details to be clarified if you want to put in a house heating system:
which depends on the used building materials (windows, insulation, construction of walls and roof
a low temperature system needs large heating areas (e.g. under floor heating, wall heating). It is a slowly working system, which needs more time to heat up the room. But the heat loss is less. A system working with higher temperature needs smaller heating areas (e.g. radiators), but requires a higher temperature and entails higher heat loss. It is a quicker working system.
Way of heat production: solar energy, gas heater, oil stove, wood burner, electrical energy (e. g. heat pump).
a) Solar energy is suitable for a low temperature working system, but it needs always a back-up for days without sun.
b) Gas boiler and oil burner (fuel) can be used in either low or high temperature working systems.
c) wood burner (with back boiler) can be used in both systems but should be connected to a storage tank in case of an under floor heating.
d) Electrical energy should be applied for heating only if be used together with a heat pump. Otherwise it would not be appropriate in terms of ecology and economy.
All heating systems can be installed in combination. But this cannot be explained in a brief description, because it depends on the clients requests and on the architectural house conditions.
