Quick answer
EcoComfort uses two separate tanks: one supports cooling and heating energy for indoor terminals, while the other supports domestic hot water. The two water volumes are not interconnected.
Tank A: comfort energy
Tank A stores chilled or heated water used by indoor hydronic terminals for space cooling and heating.
Tank B: domestic hot water
Tank B supports domestic hot-water production. It remains hydraulically separate from the comfort-energy tank.
Why separation matters
Separate storage allows different operating temperatures, control priorities and hygiene requirements to be managed independently, while the heat-pump system can coordinate energy production according to project logic.
Frequently Asked Questions
Do the two tanks share water?
No. The two tanks are separate and their water circuits are not interconnected.
Can one heat pump support both functions?
EcoComfort is designed around a heat-pump unit connected independently to heat exchangers associated with each tank, subject to final equipment configuration.
Why not use one tank for everything?
Cooling/heating storage and domestic hot water operate at different temperatures and have different functional requirements, so separation supports clearer control and system design.
