Instantaneous water heaters: Efficient hot water preparation on demand
Optimize your energy balance with modern instantaneous water heaters – for instantly available hot water without storage losses, ideal for sinks, showers and commercial installations.
Modern instantaneous water heaters for on-demand comfort
Decentralized hot water supply is becoming increasingly important due to rising energy costs and hygiene requirements. An instantaneous water heater heats the water precisely when it is needed. Unlike traditional storage systems, there are no standby energy losses, as no water needs to be kept warm in advance. This makes it the ideal choice for modern bathroom designs, office kitchenettes, or high-traffic public restrooms.
Our technological solutions for water heating:
- • Electronically controlled instantaneous water heaters for precise temperatures
- • Compact instantaneous water heaters for hand basins
- • High-performance, high-voltage appliances for shower and bathtub
Efficiency and hygiene are key: A significant advantage of an instantaneous water heater is the prevention of stagnant water. Since no large volume is stored, the risk of Legionella growth is significantly reduced. Electronic models also precisely regulate the heating output according to the flow rate and inlet temperature, which can reduce electricity consumption by up to 30% compared to hydraulic units.
Technical integration and performance classes
When selecting the right instantaneous water heater, the required flow rate is crucial. While small, plug-and-play units with 3.5 kW are often sufficient for a hand basin, showers require powerful units starting at 18 kW. Modern wireless remote controls or app-based systems now also allow you to select your desired temperature directly in the shower cubicle, while the unit itself remains discreetly hidden in a cupboard or behind an access panel.
Frequently asked questions about hot water technology
An electronic instantaneous water heater maintains a constant temperature, even if the water pressure changes. Hydraulic units often react with temperature fluctuations when water is drawn from another part of the house.
Due to the high electrical power required, the connection of an instantaneous water heater must be carried out by a qualified electrician. This is for safety reasons and is often a prerequisite for the manufacturer's warranty.
