When I attach the hose to the Flow pipe with everything closed water pressure initially caused air pressure in the un-bled system to rise. The joints can then be tested with soap solution as you would with...

    Any comments on this one as a replacement for the RWB2? Will it work on the same wires that are connected in the RWB2? http://www.honeywelluk.com/products/Temperature-Controls/Temperature-TPI-Control/Sundial-RF2-Pack-3/ Any other compatible wireless or non wireless?

    Best replacement for Landis & Gyre RWB2 CH Programmer

    Thank you for the prompt replies. Regarding the gas fire part of the back boiler system, the gas fire would be used in milder parts of the year with main CH turned off. I will look into location of any pump?
