RE: My horrific Samsung heat pump installation and experience

Yes but this reduces the remaining voltage (pump head) available not the current (flow). And friction losses don't cause a temperature drop they cau...

RE: My horrific Samsung heat pump installation and experience

Sorry but the analogy doesn't work. Pipes convey heat from one end to another according to your equation, they don't dissipate it according to this e...

RE: My horrific Samsung heat pump installation and experience

In the analogy you are trying to draw, the voltage is the pump head (pressure) not the water temperature. The flow rate is the current and the impeda...

If you haven't already you might want to re-read my earlier post which has a link to a worked example of spatial zoning and draws some analogies betw...

RE: My horrific Samsung heat pump installation and experience

Are you certain of 6.5C, Have you checked the actual temperature at the output of the Samsung?. If so, are the pipes insulated and are the flow rates...

RE: My horrific Samsung heat pump installation and experience

Im not sure how helpful the analogy is. The key point is that the buffer is (at DC) most probably a relatively low impedance path compared to the hea...

RE: My horrific Samsung heat pump installation and experience

Good, we agree then! The problem is to persuade @iantelescope and, more to the point, his installer. My personal theory (based on what @iantele...

Sorry, but I don't believe in buffers (unless there is a proven need) and there won't be one in my system. OP asked where to put a buffer in his curr...

RE: My horrific Samsung heat pump installation and experience

I can see that works when there is no HEX. Basically if the rads are wide open the low impedance route is through the rads, if they close then the bu...

In the return, two pipes only. All it does is increase system volume. By putting it in the return not the feed its at a slightly lower temp, which s...

@iantelescope If it works, and it sounds like it does, that's great. The only things to remember are that the rads/pipework are probably design...
