My heat pump is 5 years old and has never leaked refrigerant. I also collect the condensate for the gardens.
Anytime you have a technology that is marketed ubiquitously as if it's a silver bullet solution, you are going to have disappointed users and implementations that under deliver. Of course it's extremely important to switch people to electrified heating systems, regardless of their efficiency. However it's a little disingenuous to pretend there is nothing but upside here.

>> Of course it's extremely important to switch people to electrified heating systems, regardless of their efficiency. You could use a gas fired heat pump. It won't work as an air conditioner, but it won't stress the grid and could even work when the power goes out.
It seems ridiculous that refrigerator leaks are not "an uncommon occurrence". Does anyone have any insight into why this would be?
> I do not fault the particular pump that we bought or our installers who were careful and professional. Apparently, however, we lack good rules of thumb to predict how a pump will perform in a particular installation. A 278% estimation turning out as 150% real world performance, certainly was not done very carefully.
I wonder if we will ever see them switch to R-1234YF refrigerant. "While R-134a has a Global Warming Potential of 1300, R-1234yf’s GWP is less than 1." The only issue is the higher pressures and the fact that it's somewhat flammable might be why. I will say, my heat pump dryer, while it has removed some buttons from shirts, has exceeded my expectations on energy usage. It's night and day compared to my toaster I had…
In your experience, does your heat pump dryer actually dry in a similar amount of time to a conventional electric dryer?
My current one is as gentle as air drying, no destruction at all.

If you are the type of person who goes "oh crap I need to wash every piece of clothing RIGHT NOW" then heat pump isn't for you because of the time penalty.

AFAIK gas furnaces still need electricity for the fans to work. When you have no electricity you at best have a glorified fireplace. It's probably going to be a worse than a regular fireplace because it's not designed to output heat to its surroundings.
