Leaflet: DHW-Tank Plug-IN

Product catalog summary

Overview: This document provides technical specifications and assembly instructions for DHW-Tanks with capacities of 300L, 400L, and 500L. These tanks are designed for efficient utilization of solar energy and are ready-to-use with simple assembly.

Technical Specifications:

The tanks are made of steel with a 50 mm PU rigid foam insulation and a grey synthetic jacket. They include a magnesium sacrificial anode, thermometer, and two welded-in bare tube heat exchangers.
Each tank has a maximum operating pressure of 10 bar and can withstand temperatures up to 95°C for domestic hot water heating and 110°C for solar circuits.
The tanks come with a pump station set DN 25, which includes a flow regulator, pump, non-return valves, safety valve, manometer, and thermometers.
A single-circuit solar control unit with a large display and three sensor inputs is included. It features a factory-activated START function and functional installation check.

Assembly Instructions:

Connect the solar supply (VS) and return (RS) lines.
Attach the collector sensor (S1) to the solar control unit.
If using a heating backup, connect the boiler supply (VK) and return (RK).
Install the existing boiler sensor into the sensor well (FK).
Mount the retaining bracket for the expansion vessel and connect it with an armored hose.
Plug in the solar control unit using the preset program “0”.

Recommendations for Dimensioning:

For 2-4 persons, a 300L tank with up to 7 m² collector surface is recommended.
For 3-5 persons, a 400L tank with a 13 m² collector surface is suitable.
For 4-6 persons, a 500L tank with a 13 m² collector surface is advised.

Additional Features:

Optional exact measurement of heat with a flow volume sensor is available.
Supplementary electric heating (EHZ) can be integrated.
