You can make your own smart water

SOLARWATT solutions for hot water preparation

Solar power for the heating element

The costs for the preparation of hot water make up a large part of the electricity bill in private households. However, they can be significantly reduced by integrating a radiator to generate hot water in your photovoltaic system. You can easily retrofit them or have them installed as part of the installation of a new PV system. The PV system ensures a self-sufficient hot water supply from April to October.

The connection of a photovoltaic system and a heating element has the following advantages:

  • Water heating costs decrease by approx. 40%
  • Increase in self-consumption
  • increased independence from the electricity provider

SOLARWATT offers you ready-to-use solutions to optimize your own consumption with water heating. The system can also be expanded to include intelligent energy management using the SOLARWATT EnergyManager - this is how you use your solar power efficiently.

With SOLARWATT solutions, you can maximize your own consumption of free solar power right from the start. The SOLARWATT EnergyManager controls the entire energy flow in the household and also optimizes hot water preparation. The heating element is switched on even with a small excess of solar power. The times of connection can be programmed, as well as the priorities, if z. B. only another consumer should be served.

DHW heating with the EGO Smart Heater

EGO Smart Heater, the robust and inexpensive screw-in heater is easy to install. It can be controlled time-based or solar-optimized via Ethernet via the EnergyManager.

If at least 500 watts are available from the PV system, the heating element begins to work. The EGO Smart Heater can be operated in steps of 500 W up to 3,500 W. This saves heating costs and also lowers the CO with oil or gas heating2Emissions.

Store solar power as hot water

If the solar system is connected to a domestic water heat pump, the water in the storage tank can be heated to up to 60 ° C in sunny times. Temperatures between 45 and 50 ° C are common.

The calculation is simple: the higher the water temperature in the thermal storage tank, the longer hot water is available, even when the sun is not shining. On the one hand, it takes some time for the water to cool down again. On the other hand, a larger amount of hot water is available.

This is based on the following principle: When hot water is drawn from the tap, hot and cold water are mixed together using a mixer tap in order to achieve the desired water temperature. The higher the initial temperature of the water, the more cold water is added - the amount of hot water required is reduced.
