If it is of interest I have been using a tmv backwards for solar for a few months now.
It cost me £15 on ebay I pulled out the two singe check valves which would have prevented reverse flow.
It works wonderfully well.
Regards Alpha all I am saying is they are sufficiently fluid as an organisation to adopt innovative technology. What I was told about gassaver at the time i was there was that the inventor took it to all the main manufacturers and they all sent him away. Alpha had to pay as much for it as they charge. But they took it on board because it is a good sales tool into development property where the developer only gains planning permission because of achieving certain efficiency targets.
Like all efficiency tricks it may not be stand alone finantially viable but it opens doors.
