So this is incredibly important to understand that those models are newer, and when you install them, they have to go through permits and as any other appliance replacement. But one important thing is that those systems should go with the with the expansion tank, which is required by the city.
They will absorb the extra pressure build-up, and they will help to avoid the risk of explosion. And those systems, they have to be plugged in, so you need to run a wire. So the, the most important tip is make sure to work with a contractor who has experience working with those heat pump water heaters because they're different than just regular tank gas water heater.
