Buffer tanks
The importance of storage tanks
Accumulation tanks are made of high-quality steel and are intended primarily for biomass boilers. They are used to accumulate excess heat that is generated by burning biomass and that cannot be used at a given moment for heating radiators or other heating. This accumulated energy can be used later and distributed to the heating system, e.g. in the case when your fuel dose in the biomass boiler has already burned out. Depending on the size of the tanks, you can extend the burning time per load. Last but not least, the use of accumulation tanks reduces fuel consumption, extends the life of the boiler and the boiler can also be operated in transitional periods at the operating temperature of the boiler.
Advantages:
- higher operating comfort
- lower fuel consumption - the boiler operates in an optimal operating mode with higher efficiency
- longer boiler and chimney life
- less tar and acid formation when operating at rated output
- can be used with radiator and underfloor heating
On the market you will still come across storage tanks that are supplied with soft polyurethane insulation 100mm thick with a Lambda value of approximately 0.04, which show high heat losses and are in energy class E or D. Our storage tanks are supplied with hard EPS insulation (hard EPS grey) 100mm thick in energy class C. This hard insulation is characterized by its shape stability, but mainly by its very low Lambda value, which has a value of 0.032, i.e. excellent insulation properties.
For a better illustration, please see the table of energy losses of storage tanks depending on the volume and energy class for volumes of 500 and 1000 liters.

Each insulation is cut to size for each storage tank and the leatherette cover with a zipper. Each insulation has pre-cut holes for the individual outlets from the storage tanks.
The top cover is made of 2mm thick PVC, supplied with a zipper and in RAL9006 - silver.
The individual exchangers in the PSR and PSRR storage tanks are made of stainless steel.
