GEMA Instantaneous Water Heater Pro 9 kW – compact auxiliary and emergency heating for heating systems and photovoltaics

Product overview

The GEMA Instantaneous water heater Pro is a flexible solution for additional heating of heating or Drinking water cyclesIt is available in two power levels (6 kW and 9 kW) and is ideal for emergency heating, additional heating or for converting excess PhotovoltaicsEnergy into heat. With a compact design of just 47.2 cm in length, it easily fits even in tight utility rooms.

Advantages and features

The robust Stainless steel heating element ensures consistently high efficiency and a long service life. Thanks to the integrated temperature controller, the water temperature can be continuously adjusted between 30°C and 85°C, while a safety temperature limiter at 110°C provides additional protection. An insulated housing minimizes heat loss and ensures safe operation.

The Pro Instantaneous water heater has a factory-mounted Heating cartridge and a two-meter-long connection cable. A wall mount, screw fittings, and seals are included, so you can put the device into operation immediately.

Easy integration and installation

With a 1¼" external thread connection and a protection class of IP54, the Instantaneous water heater Can be used in both protected indoor areas and damp rooms. The three-phase power supply (400 V) without a Schuko plug allows for easy connection to existing electrical installations. The built-in isolating transformer ensures safe separation between the mains and heating circuits.

Areas of application and possible combinations

The Instantaneous water heater Pro can be seamlessly integrated into central heating systems with heat pumps, oil boilers, wood gasification boilers, or pellet boilers. As an auxiliary heating system, it supports peak load coverage and prevents the main boiler from running on during periods of high hot water demand.

It is particularly clever to use it in conjunction with PhotovoltaicSystems: Excess solar power is directly converted into heat and stored in buffer storage. This actively contributes to reducing your electricity consumption and increasing the self-consumption of your PV system.
