I am in the process of purchasing a new heat pump. Thanks to the help of this forum, it is going to be a 2 ton Trane XL15i and a 2.5 ton variable speed air handler with a 7.5kw heat strip.
I am borrowing my parent's Eden Pure 1500w space heater. They claim it will heat 1000sqft. The thing is pretty darn good. My indoor temp was 60 degrees and I put this thing on and in 20 minutes it was 63 degrees in here with an outdoor temp of only 24 degrees.
It got me thinking. Would this thing be more efficient than firing up my HP and air handler?
I asked my brother and we are both stumped as to why using the heat strip in the air handler is less efficient than using the HP to warm the house. We were thinking that just heating with the heat strip sounds like it would be more efficient than firing up the outside condensing unit. Can you explain why a HP is more efficient than the heat strip at any temp. You have to run the outside pump and fan as opposed to just the heat strip in the air handler, correct?
