"The petition, if implemented by the EPA, would require homeowners to replace gas appliances when they break down or must be replaced with expensive new heat pump technology."
Assuming a heat pump lasts about 10 years, Has there been any analysis of the supply chain dependencies or repairability of heat pumps? I've asked this elsewhere and have had trouble figuring this out.
Saying this as someone currently fixing an old house, made haphazard 'kotatsu' heating setups, seen plenty of videos and articles evangelizing heat pumps, yet feel like there's little asked about the long term resilience or repairability of a given tech despite the greater efficiency.
- msh 4y agoI think they last a lot longer than 10 years. I am not in the US but have been looking at air to water heat pumps and several of them are sold with 15 years warranty.
- smileysteve 4y ago> Assuming a heat pump lasts about 10 years Residential heat pumps are estimated to last 20-25 years; with typical services being capacitor changes, electromechanical contactors, and coil cleaning. Digital thermostats from 15 years ago prevent the most common compressor issues. Smart thermostats can now detect symptoms proactively. In the last 15 years, we've seen technological advances in compressor, gas, and electronics (as well as air to ground and air to water). And better calculations for sizing and air quality.
