Hot water cylinders

Hot water cylinders: selection and advice

A hot water cylinder keeps heated drinking water ready. In combination with a heat pump or photovoltaics, it can help you use self-generated energy.

Cylinder volume, installation location and the planned heating method are important. The number of people in the household gives a first indication of the volume. You should also measure the connection position and room height in advance.

We currently carry two cylinders from the SOLITANK brand, which you can combine with a heat pump or photovoltaics, provided the product page names this heating method.

Do not size the volume too tightly, and think about getting the cylinder into place: a filled cylinder is heavy and must fit through doors and the stairwell. Connections to the heating and drinking water belong in the hands of a specialist company that also takes care of the safety valve and insulation. You will find further cylinders in the Stiebel Eltron and PV hot water heater collections.

Frequently asked questions

What number of litres suits our household?

That depends on the number of people, showering habits and heat generator. A fixed number of litres cannot be given across the board. Tell us your household size and heating system, and we will suggest suitable cylinders from our range.

Can I run the cylinder with PV?

Depending on the version, yes; check the product page.

Do you carry out the installation?

Please contact us directly about this. Alternatively, commission a local specialist company with installation and commissioning; on request we will give you the item data for its quote.

    Out of stock  Delivery time depends on the product. Freight shipments take longer, by appointment. Items marked “To order” are only ordered from the manufacturer and may therefore be delayed.

    Solitank - Ideal for heat pumps The coil is the hot water consumer The tank is heated by the heat source The heat pump is connected to the tank In the Solitank, 1 heat exchanger and 4 couplings are connected to the tank body. The domestic hot water is heated immediately by the upper heat exchanger. In the couplings connected to the tank body, the water can be heated by a heater (heat pump, boiler) and used for heating preheating. (see figure x) Solitank can store in 2 different versions at the same time, depending on system requirements. It can be used as a domestic hot water tank and as a buffer tank. The hot water stored in the tank is used both for heating support and for heating domestic water. The heat exchanger in the tank is made of chrome-nickel 316L stainless steel. Because the domestic hot water tank is heated, the growth of legionella and other bacteria is ruled out. Several heat sources can be integrated into the Solitank. Optionally, it can be operated with an electric heater. As a non-solar heat source, this is the most efficient model. It is perfectly compatible with heat pumps. Housing for notes and maintenance.
