I have been searching the forum for instructions and came across the following:
If ChrisR reads this could he explain what he means by item 3, particularly the "work out for pipe" bit?
ChrisR said:Simple:
1. See boiler instrs to see what flow rate is required.
2. See pump curve to see what pump head will produce that.
3. See boiler instrs to determine head loss through boiler, then work out for pipe, at that flow rate.
4. Set ABV to pump head minus flow head losses.
