Danfoss HP22 22mm 2 Port Motorised Zone Valve - Reliable Zoning for Radiators & Underfloor Heating

Description

Take precise control of your central heating with the Danfoss HP22 motorised zone valve. Designed for 22mm pipework, this robust 2 port valve opens and closes on demand to direct hot water exactly where it’s needed - improving comfort, reducing energy waste, and supporting efficient multi zone systems for both home owners and trade installers.

Key Features

22mm Compression Connections

Quick, leak resistant fit to standard 22mm heating circuits.

2 Port Motorised Operation

Electrically driven actuator responds to thermostats and time controls for automatic zoning.

Compatible with Boilers & Heat Pumps

Works across common hydronic systems, including radiators and underfloor heating.

Durable, Service Friendly Design

Built for long life in typical heating pressures and temperatures easy to maintain.

Product Description

The Danfoss HP22 is a motorised 2 port zone valve engineered for reliable flow control in domestic and light commercial heating systems. When paired with room thermostats, programmers, or smart controls, it enables true zoning - sending heat only to occupied areas and cutting unnecessary runtime.

Its 22mm compression ends simplify installation on standard UK pipework, while the electrically operated actuator ensures smooth, repeatable opening and closing. The result is improved comfort, better energy management, and a heating system that works harder where you need it - and less where you don’t.

Ideal for upgrades, replacements, or new multi zone installs, the HP22 supports both radiator circuits and underfloor heating manifolds, making it a versatile choice for modern, efficient homes.
