Our DHW production and storage systems are the right choice for you if you want to store or produce domestic hot water.

Make your investment decision based on any criteria - the wide product range guarantees that you will find a solution that perfectly suits every customer requirement and every situation.

■ Innovative, reliable technology that guarantees maximum operational reliability and optimal cost-effectiveness.

■ Short heat-up times and high hot water comfort.

■ Thick thermal insulation effectively protects the heated water from losses, thus reducing energy consumption.

Enamelled storage tanks

Domestic water storage tank for heating domestic water. This is a steel tank, enamel painted on the inside, with protection against corrosion and thermal insulation. A built-in enamel painted heat exchanger.

Hoval CombiVal ER (200-1000)

Domestic water storage tank with built-in enamel painted heat exchanger (196-968 litres)

Hoval CombiVal ESR (200-400)

High-performance DHW tank for combined heating (193-379 litres)

Hoval CombiVal ESSR (500-1000)

High-performance double-screw DHW tank for combined heating (465-961 litres)

Steel buffer storage tanks

The steel buffer storage tank serves as an intermediate storage tank for the surplus energy until the heat is required in the building.

SISS (500/150 - 900/200)

Buffer tank with built-in DHW storage tank (500-900 liters)

Stainless steel DHW tanks

Where extreme durability is required – for example in areas with aggressive water – stainless steel models offer the best protection against corrosion and offer an economical solution to meet your exact needs.

EcoTherm EHSF - water heater 50-1.000 kW

High capacity water heater for water/water operation, with internal spiral flat heating coil and fibre-fleece insulation

EcoTherm EHRE – water heater 50 - 2.000 kW

High capacity instantaneous water heater for water/water operation

EcoTherm EDRE - water heater 50-2.000 kW
