Honeywell Home 22mm Angled Automatic Bypass Valve DU145-3/4B
Product Overview
The Honeywell Home DU145-3/4B Angled Automatic Bypass Valve is a reliable and efficient solution for controlling water flow through a bypass circuit in your central heating system. Designed to be installed between the flow and return pipework—typically near the boiler—this valve complies with building regulations, which advise the use of an Automatic Bypass Valve (ABV) when a bypass is installed.
Engineered to improve energy efficiency, the DU145-3/4B only allows water to flow through the bypass when necessary, such as when zone valves or radiator thermostats close. Recommended as a Best Practice solution in the UK government's CHeSS (Central Heating System Specifications) guide, this valve ensures optimal system performance and energy savings.
