RE:RE:RE:RE:RE:RE:-55c out west anyone with an ev here have issue lol here is the latest and greatest residential heat pump capability from the 2024 CES, Highlighted red is my notes
Bosch's new heat pump, the IDS Ultra, is the company's first air-to-air heat pump designed specifically for colder climates. The model, which Bosch says can maintain a home's temperature down to 5 degrees Fahrenheit (-15C) and keep working down (at declining output) to minus-13 degrees (-25C), is one of several that has passed the first stage of the Department of Energy's Residential Cold Climate Heat Pump Challenge. Others include products from Daikin, Midea, Johnson Controls, Lennox International, Carrier, Trane and Rheem. So in essence, heat pump we can buy today is good for -5C, after that you better have supplemental heating. Below -25C, good luck, heat output = 0. Imagine how many days canadian winters are colder than -5C, and do the math from there.

Heat Pumps Can Struggle in Coldest Winter, But New Models at CES Show Promise (msn.com) mrbb wrote: i see a heat pump is a good equip to have around the house. It can supplement heating and cooling during the extreme cold and hot days. Since canada has more extreme cold than extreme heat, i would still chose a good old reliable NG/oil/wood fuel to do the main load.
