Electricity is getting greener and greener.

The share of renewable energies is increasing more and more. Use renewable energies for hot water supply instead of limited fossil sources!

2

Separate heating and hot water!

Modern heaters require low flow temperatures. It makes sense to separate the systems from each other.

3

The future belongs to electric instantaneous water heaters.

When heating is separated from hot water, energy-efficient instantaneous water heaters are a convincing decentralised system for supplying hot water.

4

Sustainable, efficient and economical.

E-instantaneous water heaters are comfortable, space-saving and offer a high level of hygiene and safety. They heat the water only when required at the desired temperature.

5

Replace old devices and schedule new ones.

Become an energy saver and exchange outdated technology. Plan your next sanitary design with electric instantaneous water heaters.

6

Immediately to temperature

When the tap is opened, the water flows immediately at the desired temperature. It is also only heated as long and as much water as is actually needed. Thanks to short water lines and modern technology.

Desired temperature

The individual desired temperature can be set precisely to the degree on most E-instantaneous water heaters. Directly on the device, by radio remote control or by app.

Saves operating costs

Electronic instantaneous water heaters save up to 85% energy compared to conventional systems.

Environmentally friendly

The process through to the finished product is particularly sustainable for us and is constantly put to the test. We work according to the environmental management standard ISO 14001. Users save water and energy with electric instantaneous water heaters.

Conserve water

Now that's cool! No waste of water. Hot water is immediately available with electric instantaneous water heaters. You don't have to let water flow for long to get the desired temperature. In central systems, approx. 4.8 litres of water are wasted in 15 m long pipes.

Efficient

Long water lines and circulation losses are eliminated, as the units are installed directly at the point of use. The water is not preheated and stored in large quantities. This saves energy. In addition, investment costs are saved: long hot water pipes, circulation pumps and hot water tanks are not necessary.

Short water lines

E instantaneous water heaters are installed directly at the point of use. Long water lines are avoided. Water heats up faster and there is hardly any heat loss.

More hygiene

E instantaneous water heaters heat the cold water directly at the tap to the working temperature in seconds as it flows through the unit. The heated water is consumed immediately and too much unused water in the piping systems is avoided. Thus no legionella test is necessary. This makes decentralised water heating more hygienic and efficient.

CO2 down

The share of renewable energies in the electricity mix is increasing, thus also reducing CO2 emissions resulting from the conversion of fossil fuels. Compared to central gas or oil systems, CO2 emissions are reduced by up to 35% of decentralized hot water supply.

Class A for our instantaneous water heaters.

The energy labels for hot water appliances confirm that decentralised water heating with electronically controlled instantaneous water heaters is one of the most energy-efficient technologies.

What the energy label means.

The European Energy Label identifies the energy consumption of electrical appliances during their use. Thus, electrical appliances for hot water supply, e.g. instantaneous water heaters or hot water storage heaters, are currently rated energy efficiency classes from A+ to G, where A+ is the best class (low energy demand) and G the worst (high energy demand). The labels also contain other useful information (e.g. noise level) so that different models can be compared.

Click on the numbers in the circles in the figure below to see an explanation of the individual elements of the energy label: manufacturer name, product name, tap profile, energy efficiency class, noise level during use and energy consumption per year.

By the way:
The energetic advantage of electronically controlled instantaneous water heaters is not shown on the energy label. In practice, up to 30% energy can be saved compared to hydraulically controlled instantaneous water heaters within efficiency class A by heating as required. This is due to heating to the desired hot water temperature as required. The electronics automatically adjusts the power consumption – and thus the energy consumption – to the amount of heat used.

Summary
The energy labels for hot water appliances confirm that decentralised water heating with electronically controlled instantaneous water heaters is one of the most energy-efficient technologies.

Manufacturer name and product name

Tap profile

How powerful a device must be depends on the intended application. On a hand-rinse basin, for example, a water flow rate of approx. 2 litres per minute (tap profile XXS) is sufficient, on a kitchen sink approx. 5 l / min are required (tap profile XS), while the supply of several outlets in the bathroom or in an apartment requires a water flow rate of approx. 10 l / min (tap profile S).

Energy efficiency class

As with household appliances, the seven efficiency classes are classified according to the traffic light system: a green color bar stands for the best efficiency class A and a red bar for the worst efficiency class F. In a comparison of the different hot water systems, demand-oriented instantaneous water heaters were classified with the very good energy efficiency class A.

Noise level during use

The noise level of all CLAGE instantaneous water heaters is a low 15 dB and is therefore hardly perceptible.

Energy consumption per year

But not only the energy efficiency class is decisive, but also the detailed information on the label. Within an efficiency class there are considerable differences in energy consumption. First select the water heater according to your needs, i.e. according to the tap profile. It is important to compare the annual energy consumption!
