Here is some actual data we can discuss (link to data): Hypothesis: does reducing the flow rate on a DHW cycle increase the dT, allowing more time f...
I have an NRG Zone and the DHW circuit is taken off one of the "zones". This "zone" has a dedicated circulation pump which I have reduce the speed on....
Lets prove it with a fairly simple test. We do a lot of talking about this stuff in this industry, yet I do not see much empirical evidence... anywher...
I have temp sensors on the flow and return of the DHW circuit. I've reduced the pump speed from 3 to 1 for todays cycle/test (roughly 23L/min to 10L/m...
This is a very valid point, one that could be modelled out quite easily

Hi James, firstly - thank you for contributing to this discussion, it's very much appreciated and quite enjoying the challenging of the ideas/concepts...
Yes, this is what I believe to be the case. The theory has two principles. 1. Ignoring pure weather compensation, instead run the HP in its most o...
Yep, can’t disagree with that. I must admit, I was highly motivated by performance and everything else was an afterthought.
I would like to agree with you, I really would. However, the data (my HP) shows otherwise. Oversizing is not as detrimental as people are led to belie...
