Sizing & Selecting Air Source Heat Pumps in Cold Climates

[Buc_Stops_Here]

I have an older Lennox heat pump that is 10 years old, using existing duct work. It works down only to 38 degrees. In CT, in the cold of winter, I go back to oil during the nights (and days) when it is below that point. I am going to do research to understand how low the center heat pumps go today. The system I have now probably will need replacement in the next few years and this video is encouraging that it may work with a lower temperature.

Which heat pump is better, Daikon or Hitachi?

This video is a bit old. Mitsubishi and LG both make cold climate models. Ducted and ductless indoor units are available. Mitsubishi even makes a dual fuel system. Make sure to size the unit to the heating load.

I thought the idea behind these minisplits was being able to service up to 8 zones efficiently. I’m remodeling an older home now and will need four zones to properly service the home. Is that bad?

What if the system is still? the water are still

So how would the heat get around a 3500 sq ft house without duct work?

All these are in the U.S.A they don't install they throw them in .

According to the laws of thermodynamics, heat flows from hot to cold surfaces. So, if it's cold outside, how can these heat pumps possibly draw warmth into the property?

No useful information from this video. Thumbs down for you.

Not making people understand that getting rid of their oil heater and the power goes out you won't have heat possibly for days.

What a load of tosh don't believe a word just jumping on the band waggon .Heat pumps are cheaper than oil but nowhere near as cheap as gas heating .
