: Good, there are actually numbers and temperatures to work with, up to know it has been conjecture. It shows that there is no significant pressure drop across the ErgoMax piping as it is, so there should be no pressure difference to be concerned with between the feed pipe from boiler to the return pipe from the Ergomax to the boiler; so there should be no need to be concerned with the 0010 overpowering the 007's.
+++OK, but then I don't understand why the 0010 pushed hot water forward through all the zones when the supply header was attached at the supply from the boiler to the tank?
When the plumber comes in the next week or two to hook up the DHW through the Ergomax, I will have him measure pressures on either side of the bypass valve and post them here.
Thanks.
