Set and forget or programmed minisplits. Which is more efficient?
Just came across this website. Amazing and knowledgeable resources here.
I have a question around the set and forget vs programmed mini split heating functions. I have a two story with finished basement that has hot water radiation. I installed a two head Panasonic mini split in July and was really hoping for lower heating bills. I just got my December bill and the actual kilowatt usage was higher this December vs last year.
I have the main floor 18000 BTU programmed to come on at 6:30 am and shuts off at 9:00 am. As well, it comes on again at 2:30 pm and shuts off at 11:20 pm. The second head is in a relatively large bedroom and we only use it as needed. The remaining bedrooms are one a seperate hot water zone as well as the basement.
My question is should I leave the minsplits on all the time with a comfortable temperature or continue with the programmable features. A December bill of over $600.00 is something that I am trying to avoid in the future.
I live on the East Coast of Canada where the temperature ranges from 5 C to -10 C in the coldest months of winter.
Thanks for taking my question.
