Solar power for the water heating

Collector surface size: 1.5 m² of the flat collector per person. Tank capacity: there should be 60 up to 80 liters per square meter of the collector which suits the one and a half or double daily consumption of the water.

Correct planning and the production saves about 70% of the power used for the water heating! Give sun the chance and give your boiler a summer break.

Solar devices for the heating support and the water heating; Collector surface: in the well isolated house (NEH standard) is necessary about the 1m² of good flat collector per 10m² of the living space.

Tank capacity of the combined tank shall be: 50 liters per the square meter of the collector with the addition of 50 liters per person. In case of the 12 m² device which provides for 4 persons the tank capacity shall be 800 liters.

Solar device as a heating support can save about 25 - maybe even 30% of the heating energy. Crucial are the type and the position of the building and the quality of the isolation. This device is meant for heating during the cold summer days and for the transient periods.

Brauchwasser = consumable water; Solarspeicher = solar boiler; Sonnenkollektor = solar collector; Regelstation = regulation station; Heizkessel = central heating boiler.
