This automatic bypass and differential pressure valve from Honeywell Home is brilliant for maintaining constant differential pressure in your heating system. It minimises flow noise when thermostatic radiator valves are closing. The boiler return temperature is also raised to prevent corrosion from flue gas condensation.
