Hi,

First Post - replaced out 16 year old gas boiler with a Midea 10KW R32 MonoBloc, already have a south facing 9.6kw Solar array and Tesla Powerwall and EV so ASHP was next logical step.  Heal Loss was calculated at just under 8Kw for our 165m2 detached house.  Install required 8 rads replacing.  Still on steep learning curve. Install was through Puraflow.  Pre Sales, and install was good, great communication.  Shame I cant say the same for post installation support. Main issue we have is the Smart Home App and the wall unit keep losing connection.  Sorted problem myself by the usual  - reboot of the wall unit (i.e. switch off via fuse board). It then works OK for anything from 5-10 days before losing connection again.  Our Wifi is good, 900MB Fibre to the premises, have them on the 2.4Ghz , no issues with any other household devices. Any one else have similar issues. Nothing from Puraflow. 

 

Currently we have an extremely basic set-up using wall thermostat and a schedule that makes some use of our overnight 7p EV rate for water and to get slightly warmer before 05:30am . We have water set to 49C at night and 45C during the day.  We mainly have 19C for the day, with a 18C between 6am and 2pm, then back to 19C.  Puraflow did not give us any information of using the weather compensation.  House if lovely and warm, we have a big log burner, but hardly needed to use it. 

 

Thanks for any ideas - or point me to some reading material. 

 

Steve
