13. Why should I invest in accumulation tank, is it necessary ?

Question:
Why should I invest in accumulation tank, is it necessary ?


Answer:
There are several reasons why to invest in accumulation tanks. The first reason lies in better control of the heating system, where the water temperature in the system does not fluctuate under varying temperature in the boiler depending on fuel addition, but its value is constant for accumulation tank as necessary in a heated building. Another reason is the total fuel savings because the boiler heats the storage tank using its full output . Wood gasifying boiler reaches it's maximum efficiency at it's maximum output and thus longest life of the boiler is guaranteed. Total fuel savings in combination with the accumulation tank may be up to 30%.
