Accumulator Tanks These are necessary for the boiler to operate to optimum efficiency by carrying out the following three functions:- 1. To act as a heat store allowing the boiler to run for longer periods whilst charging the tank as these are the ideal operating conditions for biomass boilers. 2. The tank absorbs heat from the boiler when in stand by mode e.g. 25kW will give off 5 kW/h and the tank will absorb this even when fully charged. 3. The tank acts as a thermal store between the boiler and the heating system. This allows us to undersize the boiler so when the heating and/or hot water heating is turned on and is drawing more heat than the boiler can supply the heat that is stored in the tank can be slowly used up and then replenished later – perhaps overnight. It is very important to maintain the layering of the hot water inside the tank – ‘stratification’. This means a distinct layer between very hot and warm water and this is achieved by the Laddomat thermoregulator when filling the tank.
