Connection With Heat Accumulators - ATTACK DPX15 Instructions For Use Manual

Connection with heat accumulators

Connection system is based on principle of heating up of water in accumulation tanks, where the
warmth is gradually taken away from the tanks according to the request from the heating system.
By the operation with several heating ups at full performance, accumulation tanks will be
heated for the temperature of 90-100°C. Heating with accumulation tanks in connection with the
ATTACK DPX boiler brings more advantages. To the main advantages belongs longer boiler life-
time and also lower consumption of fuel. Recommended volumes of accumulation tanks according
to boiler output are following:
DPX25 - 1500 - 2000 l
DPX35 - 2000 - 2500 l
DPX45 - 2500 - 3000 l
Operation with accumulation tanks
After heat-up phase, the boiler heats the water in the accumulation tank to 90 - 100°C by full output
in 1-3 feedings. After burn-out, the heat is taken through the three-way valve only from the
accumulation tank. The offtake period depends on the tank volume and external temperature. In
heating season it can be 1 - 3 days (if the prescribed min. volume is respected). If it is not possible
to use the prescribed volume of the tank, it is recommended to use at least one tank of 500l volume
for start and finish boiler operation. Minimum volume of accumulation tank is given in the tabel
of technical parameters.
