Ideas to improve it
- Make the vacuum chamber larger diameter = more water processed each cycle and larger surface area to disperse micro bubbles.
- My fill flush is on the return , so not the hottest part of the system, better to connect to flow.
- If you don’t have separate fill and flush valves then should be possible to use fill only valve , with the feed to and from the degassed teed together as close as possible to the fill valve.
- Put a Willis heater in the inlet pipe , so water can be got nice and hot without thrashing the heatpump. Maybe some safety concerns?? PRV needed etc.
