There are some details to be clarified if you want to put in a house heating system:

• Heat demand:
  which depends on the used building materials (windows, insulation, construction of walls and roof).
• Heat distribution:
  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).
• - Solar energy is suitable for a low temperature working system, but it needs always a back- up for days without sun.
• - Gas boiler and oil-stove(fuel) can be used in either low or high temperature working systems.
• - A 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.
• - Electrical energy should be applied for heating only if be used together with a heat pump. Otherwise it would not be wise 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.
