Connection package – The practical installation kit for your combi storage tank

Product overview

The combination storage tank connection kit offers you a universally applicable mounting kit for the needs-based connection of combination buffer tanks, stratified combination tanks, and hygienic combination tanks. It enables the easy integration of steel storage tanks with integrated hot water heating and ensures optimal heat distribution.

This set makes connecting your buffer tank not only more convenient but also more secure. The included connection insulation plugs for all 1.5-inch connections ensure that unused internal thread buffer connections are reliably sealed.

Advantages and application

A key advantage of the connection package is its universal applicability. It is designed for buffer tanks with up to eight 1½-inch female threaded sockets for charging connections and two 1¼-inch male threaded sockets for hot water connections. The system, with its hydraulic diagram, enables quick and straightforward installation, so installers can rely on a practical solution.

The temperature difference between heat dissipation with and without insulating plugs (approx. 70°C versus 18°C) shows how efficiently the package contributes to minimizing heat loss and making optimal use of energy.

Technical details and assembly

In addition to the connection insulation plugs for all 1½-inch connections, the set also includes important components such as quick-acting air vents, boiler fill and drain valves, and universal ball valves. These components ensure smooth operation and easy maintenance of the heating system.

The package also includes an LK hot water/drinking water mixer with scalding protection, which can be adjusted between 35 and 60 °C. This guarantees additional protection against scalding and ensures safe use of the hot water.

Scope of delivery

The connection package includes the following components:

EXSEL12 – Quick air vent with shut-off ½", KFEH12 – Boiler filling and draining valve made of brass (½"), 4x KGH1 – Universal ball valve 1" with lever in red, 2x EXBIZ – bimetal dial thermometer with immersion sleeve (½", 0-120° Ø63mm) and HM1 – domestic water mixer HydroMix 1".
