Storage tank

Alongside heating and cooling, all WATERKOTTE heating systems also provide you with especially convenient hot-water heating. In this way an attractive all-round package for you and your family’s needs presents itself.

With WATERKOTTE heat pump heaters of the DS series, which use the flow-through heating principle, hot-water tanks with a capacity of 300-400 litres are preferable. Where greater quantities are needed, single-tank storage volumes of up to 1000 litres are easily available. However, this is usually only necessary in homes housing several families or similar such circumstances.


Good reasons for going with WATERKOTTE: Hygiene
The hot water is stored in a hot-water tank, so you have ample hot water at all times.

With hot-water heating, the renewable energy is also used in an optimal way.With WATERKOTTE hot-water heating you avoid these disadvantages. Since no great quantities of hot water are stored away, there are no breeding grounds for germs and pathogens. WATERKOTTE uses an efficient plate heat exchange device as a base through which water from a tank between 300 and 900 litres flows. This solution keeps potable water separate from the thermal source and thus prevents germs in the boiler from being introduced into the system.

Good reasons for going with WATERKOTTE: Hot water of the same quality as cold tap water
WATERKOTTE hot water heating offers an abundant supply and the highest water quality at the same time, i.e. it offers hot water of the same quality as running tap water. The same applies at lower water temperatures that might be desired for the safety of little children, for example. To achieve this, the desired heat pool is stored on the heating side (i.e. on the primary side) in a 400 litre upright tank (at 55 °C). Whenever water is drawn from the tap, the heating occurs in a specially designed, high-performance, multiple-conduit heat exchange device at the same time the tap is turned. In this way heating water from, for example, 10 to 50 °C takes place in fractions of a second. It is know that very sudden heating has a positive effect on the hygienic condition of tap water, even improving it, should this at some point be necessary.
