Auto Bypass Valve
Central Heating Auto Bypass Valve
Automatic Bypass Valves are an essential item to maintain efficiency and prolong the life of your boiler. Particularly useful on central heating systems with TRVs they ensure a constant minimum flow of water through a boiler and reduce the chance of over-heating.
When Thermostatic Radiator Valves close, the flow around your system will lessen. When this happens, your Auto Bypass Valve will open to maintain the flow through the heat exchanger and avoid overheating.
