Grant Low-loss Headers

Header systems are a cost effective way of installing multiple heat sources and feeding more than one heating zone which have different temperature requirements. This is achieved by using a small low loss header known as a hydraulic switcher and a distributor.

Features & benefits

Depending on the system load, two sizes are available (up to 70kW and up to 165kW @ Δ t 20 °C flow and return set up temperature). The heating appliances are then connected to the switcher, which provides an open circuit for the appliance system water to feed the heating distribution header. This can be supplied with 2 to 6 Grant zone pump kit’s for each heating and hot water circuit, as required.

The Grant low loss header provides the installer and the customer with a professional installation which is both cost effective to install and run.

 Wall fixings

The header is fixed to the wall using a bracket system. These come as a pair (quantity required depends on the size of the unit) and allow a variable gap between the wall and header of between 100mm and 150mm.
