When boiler is operating at maximum operating temperature, providing heating with all heat emitters operating, pressure gauge
should not indicate more than 26.11 psi / 1.80 bar. If reading exceeds this figure larger expansion tank is required.
Available Pump Head For Central Heating
This is a high static head pump fit for installation on any type of single or double pipe heating systems. The automatic air valve
incorporated in the pump allows for quick air purging of the heating system.
