So your professional opinion is that good health dictates putting on the kettle for another cuppa to increase the humidity? 😉

Not sure I could disagree…

Ideal ranges
  • Annual range: 30% to 60%
  • Summer range: 40% to 60%
  • Winter range: 30% to 50% 

Off the internet just now for inside of house, how would I change humidity anyway?

Outdoor humidity is 88% in sunny South Lancashire just now!

It is all a bit 'finger in the wind' stuff. I have averaged my normal monthly electric use (when the ASHP was not running) and taken this months reading and simply subtracted the two to get a rough guestimate of how much the ASHP is using.

To recap

Victorian cottage with mixed levels of insulation, 212 square metres.

5 bedroom, 4 reception rooms with mix of type 22 radiators and UFH

Open loop system, no buffer or LLH, ASHP is running 24/7, flow rate is approx 35C. 

November -3.9C lowest temp and 17.5C highest temp.

908KW total / 30.3KW per day/ 1.26KW per hour

House temp is 20.2C and 41.5% humidity

So all in all I am very happy with this, more importantly the wife is happy and finds the house much warmer and more comfortable.

The 'more' button takes me to 

Setting/schedule/advance/version

It is the Advance that takes me to a password page....that's when I panic!
