Replacing Honeywell ST6300A with ....

paraboy · 21 Oct 2013

Thanks for everybody's help and advice, not really sure yet if I have a gravity or pumped system before I go and purchase the new programmer. I will try and track down the installer of the boiler and ask him the question, cheers.

Hi Paraboy, It is a fully pumped system with 2 zone valves, 1 for heating, one for water
