Installing a boiler with storage tanks brings the following advantages:
- lower fuel consumption (by 20 to 30 %), the boiler works at full capacity until the fuel burns out at optimal efficiency
- high service life of the boiler and chimney – minimal formation of tars and acids
- possibility of combination with other methods of heating – storage electricity
- designed for combinations of radiators with underfloor heating
- comfortable heating and ideal fuel combustion
- guaranteed more environmentally friendly heating
- warranty on the boiler body 3 years
We recommend connecting with batteries as the main connection.
If you cannot have the recommended volume of storage tanks, connect the boiler with at least one buffer tank with a volume of 500 – 1000 l. was able to charge these tanks in a reasonable amount of time.
Operation of the system with storage tanks
After flooding the boiler, we charge the maximum volume of storage tanks to the required water temperature of 90 – 100 °C during operation at maximum output (for 2 to 4 loads). We then let the boiler burn out. Furthermore, we only take heat from the storage tank with the help of a three-way valve for a time that corresponds to the size of the accumulator and the outdoor temperature. During the heating season (observing the minimum battery volumes, see the table) this can be 1 – 3 days. If accumulation cannot be used, we recommend at least one tank with a volume of 500 – 1000 l for balancing boiler starts and stops.
Accumulation tanks are normally supplied without insulation. A suitable solution is the joint insulation of a given number of tanks of the required volume with mineral wool into a plasterboard skeleton, or additional filling with loose insulation. Recommended insulation thickness, when using mineral wool is 120 mm. Another option is to purchase already insulated tanks with mineral wool (100 mm) in a leatherette case, which our company also supplies.
For domestic hot water heating, we can use a combined boiler or storage tank with a copper flow heater.
