I was raised on the belief that Heat Pumps could not be used in climates that really got "cold". I see the website lists -15 degrees as the operating temperature. What has changed in the past years to enable this? It seems like this would cover most of the contintental US now.
- Scoundreller 4y agoProbably better/more efficient defrost cycles. And maybe refrigerant choices.
- heatpumpfan 4y agoRefrigerant, pressure, vapor injection, and a highly "managed" vapor compression cycle.
- HEPA_As_Service 4y agoRegulation has helped a lot! Government can act as the unifier of buyer's not that long ago central systems scored 6 now this lowballs at 18. If you increase the time of operation you can earn greater return on the costs invested. Commercial water heating is storing heat cheaply now to avoid storing water warm that will be used as that causes biofilms and disease. Healthy sleep in room you want to work in upon rising creates a challenge for live pumping of heat. A sudden heat is best and that means storing from day before. We thrive sleeping in cold being woken by warmth. $20,000 on a four ton heating load is compromised by this design tragically.
