Morgan RE: Assessing Heatmiser Neostat Accuracy: How and Why to Calibrate Them  

By Morgan, 9 hours ago

  I had a Heatmiser Neostat installed with my Ecodan. I was told, I think, by Brendon that it was a simple on-off switch not suited to ASHP control. He advised stripping it out and installing Mitsubish...

  @toodles I installed so much insulation that when the installer moved a faulty room stat to another location he wired it wrong and it was two days before we realised the heating was off.

  @transparent Surely, if you need to know the OAT, the best place for the sensor is close to the air inlet for the pump? After all, that is the air that is about to enter the system. Regards, Toodles.

  @derek-m The nearest we have to a buffer is the LLH which I don’t think could hold more than a few litres at most; when the Daikin (no extra heating element involved) goes into defrost mode, the cycle...

  @toodles yup I can feel the sensor inside so likely ok. Have swung a camera around to watch how it manages the ice. At 76 it’s nice that you keep an interest in these things, I’m 66 an engineer and st...

  Why would a sensor for external air temperature be placed in the airflow being drawn through the fins? Placing it within a sleeve might provide mechanical protection, but to me, it still seems to be a...

  @david999 Ah, that I don’t know, the one on ours has a tube or sleeve over it ‘pipette style’ and suspect that yours may follow the same scheme but on the other hand, it may be protective packaging an...
RE: Aira Heat Pump: Stylish Scandinavian Heating  

By IvanOpinion, 9 hours ago

  I found the details of the warranty. I don't see any unreasonable get out clauses. And it is insurance backed. The only issue I can see is that it looks like they don't guarantee the SCOP. "The Warran...

  Achieving efficient defrosting is a problem with which a sufficiently large volumiser would probably assist, rather than using an immersion heater. When operating in heating mode the water in the volu...

  @sjn that makes sense

  @david999 the OAT sensor on the back of my 8kW unit looks the same as yours. I think the actual sensor is towards the open end of the pipe and the cable tie will be holding the pipe tight to the cable...
