DHW indirect water heater with spiral coil, floor-standing SGW(S) Tower Grand 250L, polyurethane, skay, coil 2.4m2 26-258107

Water heating heat exchanger with a spiral coil – ideal for cooperation with heat pumps

This vertical, standing DHW heat exchanger SGW(S) Tower Grand with a capacity of 250 liters is an effective solution for heating and storing domestic hot water. It is particularly recommended for systems with a heat pump, thanks to the large surface area of the spiral coil of 2.4 m². This is key, because a larger heat exchange surface translates to faster and more efficient water heating, and consequently – lower operating costs.

Construction and insulation for maximum efficiency

The heat exchanger has been designed to minimize heat loss. Insulation made of high-density polyurethane foam effectively maintains the water temperature for a long time, reducing energy demand. The aesthetic appearance is ensured by a soft skay cover and careful finishing. The design has been thought out in terms of easy installation and daily operation – hydraulic connections are located at the back of the device, and access to service elements is convenient.

Safety and durability for years

The interior of the tank and the coil are protected against corrosion with EXTRA GLASS® ceramic enamel and two magnesium anodes. The enamel creates a durable protective barrier, and the magnesium anodes further protect against micro-cracks by dissolving and sealing them. Thanks to this, the heat exchanger is resistant to corrosion and will serve without fail for many years. Energy class B ensures reasonable energy consumption. The manufacturer's warranty is as long as 60 months, which proves the high quality of the product and confidence in its durability.
