Many thanks - that is a saving, but still seems pretty high! Has anyone found inexpensive solutions to exterior insulation where there is the ability ...
Any recommendations on reasonably priced exterior insulation or alternate methods to insulate - e.g. boxing in the exterior pipes and using something ...
@skd I think the pump will raise the LWT temp to the setting for the maximum heat pump flow temperature. I increased that to 60C and during the legion...
@derek-m I think that you are correctly interpreting the algorithm that is being executed, my surprise is that the pump can run at lower power consump...
@hotheat I've dropped my min flow temp to 23, it has been a major efficiency boost once outside temps rise to around 12-15c. The pump can't modulate t...
@gary DeltaT at the point of the drop out is about 4.3C, and there is no obvious reduction of the dT after it settles post-drop-out to the next one. ...
Bit more detail: this is mine today with 4-min dropouts. Definitely not defrosts: the flow temp never drops below return and I've watched it happen, t...
@hotheat I've seen in several forums that the Ecodan will have short pauses of around 4 minutes as a form of cycling. Mine does this at temps down to ...
@cathoderay Slightly different take on this: during the colder period the delta-T looks like it was around 8 for a lot of the time, and (for my Ecodan...
To optimise, you really need real time energy consumption from the ASHP. My pump runs off an exclusive breaker in the consumer unit, and I use a shell...
I've given up on setbacks: when it's cold it just takes too long to recover even from a 1c drop and the pump has to work incredibly hard to get the re...
@crustydoodle The high temp your water got to looks the same as on my Ecodan when it had very limited volume to work on: once the pump comes on an int...
