Using the sun for DHW heating.

The Weishaupt solar cylinder.

The large solar cylinder range from Weishaupt means there is a suitable cylinder for every collector field. A cylinder with solar DHW and space heating support likewise presents no obstacle.

Benefits
Hygiene

Alongside the ease of drawing off water and the extraordinary thermal insulation and water treatment quality, the issues of cleanliness and hygiene are of crucial importance. All surfaces in contact with potable water are thus sealed with high-quality enamel or else made of stainless steel.

Highly effective insulation

Composite thermal insulation consisting of a vacuum insulation panel and high-density polyurethane foam provides excellent protection and keeps heat losses to a minimum. Efficiency is maximised accordingly.

Durability

Since no mechanical elements are built into this device, its long-term operational reliability is assured.

Renewable energy
Energy from the sun

In addition to water heaters that are supplied conventionally by boilers, there are versions that also allow solar-generated heat to be fed in. A solar collector system for DHW heating requires a special bivalent cylinder, for example. The Weishaupt Aqua Sol is equipped with two heat exchangers. The lower one is fed with solar energy, while the upper one is supplied by the heating system if there is not enough solar thermal available.

If solar thermal is to be used for space heating support as well as for DHW, a large-volume thermal store is needed. Weishupt's innovative WES thermal store preserves the solar yield with its excellent thermal insulation, ensures ideal heat distribution, and its hot-water output is outstandingly hygienic.

Products
Weishaupt WAS Sol cylinder

This is a bivalent cylinder for solar DHW heating. Bivalent means that there are two heating coils. The lower coil is connected to the solar circuit, the upper one to the heating system. If the solar thermal isn't providing enough energy, the heating system switches on automatically.

Weishaupt WAS Sol Eco cylinder

“Eco” cylinder versions benefit from increased energy efficiency: They retain heat for longer thanks to their composite insulation with vacuum insulation panels and high-density polyurethane foam.

Weishaupt WES Combi thermal store

Weishaupt WES thermal stores organise and distribute the heat produced by different energy sources (gas or oil-fired condensing boilers, heat pumps, solar collectors, solid-fuel boilers, or stoves) with an exemplary degree of efficiency. Inlet dampers ensure that the ideal temperature stratification is always maintained within the thermal store. Energy is also drawn off in an economical manner, with solar energy taking priority over any other source. The Combi-version of the thermal store has integrated DHW and solar heat exchangers.

Weishaupt WES Sol thermal store

The thermal store is charged with energy via a heat generator of any type - preferably with solar thermal energy. The stratification column utilises the physical properties of rising heat to layer the energy at the appropriate level in the thermal store, depending on the existing temperatures. The energy stored as heat can be used for space heating.

Information. Detailed, comprehensive, interesting.

Solar cylinders

Solar cylinders: Hot water courtesy of the sun.

Solar collectors can be used in addition to the existing heating system for DHW heating. To enable both to work, the water is heated in solar cylinders.
