Description
High-efficiency stainless steel domestic hot water tank
A modern domestic hot water heat exchanger is a reliable solution for homes and heating systems, ensuring convenient access to hot water all year round. The water in the tank, made of high-quality stainless steel, is heated by a coil through which water from the central heating boiler flows. This solution guarantees high efficiency and fast water heating.
An additional advantage of the unit is the option to install an electric heating element (optional), allowing independent water heating outside the heating season – an ideal solution for summer or emergency situations.
Single-coil tanks – versatility and durability
The offered tanks have been designed with maximum functionality and long service life in mind. Solid construction and proven technologies ensure the unit performs perfectly in both new installations and modernized heating systems.
- Stable freestanding design – the tank is equipped with durable insulation that reduces heat loss, along with an aesthetic metal casing or a high-quality removable casing (for 400–1000 L models).
- Stainless steel – both the tank and the coil are made of corrosion-resistant materials, ensuring long service life and hygienic operation.
- Wide compatibility – compatible with any central heating boiler: gas, oil, solid fuel, as well as wall-mounted and floor-standing units.
- Renewable energy compatibility – can be connected to solar collector systems, helping to reduce operating costs.
- Safety – factory-installed safety valve protecting the system.
- Long warranty – up to 8 years for stainless steel tanks (up to 300 L capacity), and 5 years for larger models.
- Hygienic certification – certified by the National Institute of Public Health, confirming safe use.
Why choose this tank?
By investing in a domestic hot water tank with a coil, you gain not only everyday comfort but also energy savings and reliable performance for many years. This solution combines high-quality workmanship, modern technology, and versatility, making it suitable for both single-family homes and larger installations.
