Boiler Installation/Connection with a 4-way valve
Operation of the system with heat storage units (tanks)
After the boiler is fired up and is operated at full capacity, it will heat the water in the storage tank to a temperature of about 80-
90 °C (which may take from 2 to 4 fuel loads). Then the boiler should be left to go out. Thereafter, heat is only taken from the
storage tank using a 3-way valve, which will last for a period depending on the volume of the storage tank and the outdoor
temperature.

The above listed heat storage unit s must be sufficiently thermally insulated.
Advantages of the heat storage unit use:
- up to 20 - 30 % lower fuel consumption – the boiler operates at full output capacity giving an optimum heating coefficient of
performance.
- high lifespan of both the boiler and the chimney – minimum tar and acid production
- comfortable and convenient way of heating and an ideal fuel burning conditions.
