The Honeywell Home DU145-3/4B angled automatic bypass valve controls flow of water through a bypass circuit which is installed between flow and return pipework, typically at or near the boiler. Building Regulation advice states that if a bypass is installed, an Automatic Bypass Valve must be fitted.

The Honeywell Home DU145-3/4B 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. The use of an ABV is recommended by the UK government as Best Practice in the CHeSS (Central Heating System Specifications) guide to central heating systems.

Features:

Wide differential pressure range 0.1 to 0.6 bar
22mm compression fittings for ease of installation

Customer Questions

Are your products guaranteed?

Yes all our products come with a guarantee.

Guarantees or warranties vary, by product and manufacturer.

All our products are guaranteed for a minimum of 1 year (radiators vary - see individual product specifications, copper tube 25 years) but many offer longer warranties from the manufacturer, which you may need to register for.

On each product, under the specification tab, you will find more information on the guarantee or Warranty.

Follow links through to various manufacturers sites, as each manufacturer will have its own terms and conditions for qualifying for longer warranties.

You do not want to miss out by getting the wrong installer for some boilers etc.

As Boilers and radiators are installed by third parties, they do have to install in compliance with regulations and manufacturer standards to get the full benefit of the warranty.

As long as these are fulfilled, you will get the maximum life and support from your new purchase.
