Heat pump/solar combo tank
Combo tank for integrating solar energy
Domestic hot water heating in flow principle
PWD 750
PWD 900
Upright cylinder for heating and domestic hot water preparation with central flow, with three internally tin-plated heat exchangers
(external pipework necessary); consisting of a buffer tank for heating and a buffer tank for domestic hot water; heating buffer tank used
as a preheating stage for domestic hot water preparation. A circular plate prevents the different water layers with varying temperatures
from becoming mixed together; integrated heat riser pipes distribute the energy from an additional heat generator (e.g. solar, wood boi-
ler) to the supplementary heating system and the domestic hot water preparation according to the temperature; flange connection for
integration of an optional solar heat exchanger (special accessory RWT); NTC-2 and NTC-10 temperature sensors included in the scope of
supply; 125 mm PE foam insulation delivered separately; colour: white.
PWD 750 combo tank:
200 l buffer tank for heating and 550 l buffer tank for domestic hot water; one 1½“ sleeve each for immersion heaters in the heating
buffer tank and the domestic hot water buffer tank (CTHK 635 and 636); tank charging for domestic hot water preparation up to a maxi-
mum of 2.5 m

required by the PWD 750.
PWD 900 combo tank:
250 l buffer tank for heating and 650 l buffer tank for domestic hot water; 1½“ sleeves for immersion heaters (two in the heating buffer
tank and one in the domestic hot water buffer tank - CTHK 635 and 636); tank charging for domestic hot water preparation up to a maxi-
mum of 3.0 m
