About this product

The Honeywell DU144 Automatic Bypass Valve controls the flow of water through a bypass circuit which is installed between flow and return pipework, typically at or near the boiler. Building Regulations advice states that if a bypass is installed, an automatic bypass valve must be fitted.
This reliable Honeywell bypass valve saves energy by only allowing flow through the bypass when needed i.e. when flow through the system is reduced when zone valves or radiator thermostats are closing. Use of an ABV is recommended in the UK CHeSS (Central Heating System Specifications) guide to central heating systems.
