Energy-saving water heating at home

Unlimited hot water intake gives instantaneous water heaters a definite advantage over storage water heaters. As long as you have a suitable electrical installation, there is nothing to prevent you from installing the device! Another option is to choose a storage water heater.

How do you choose an instantaneous water heater?

Flow-through water heaters are selected according to the number and type of water consumption points. At home, hot water is most often needed in the bathroom and in the kitchen. If the bathroom has a shower with a standard handset, it is usually enough to use a device with a power of 12-15kW. A heater with more power will be needed if you have a rain shower system. Then the water heating device will have to be more powerful and more efficient. In this case, a heater with a capacity of 24 to 27kW should be sufficient. A heater with a minimum power of 18kW should be used for the bathtub.
