Honeywell Dual Auto By-Pass Straight (22mm) DU144 - DU144
Honeywell Dual Auto By-Pass Straight (22mm)
Manufacturers Part No: DU144
The Honeywell Dual Auto By-Pass Straight (22mm) 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 DU144 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.

- 22mm compression fittings for ease of installation
- Reduces system noise and maintains an even system pressure
