I didn't know that these even existed for residential use but the administration is now talking about mandating heat pump hot water heaters (by 2029). I have heard about these for swimming pool heaters but now these are available for home use (Home depot sells a couple). For only $1,700-$3,000 you too could have a high efficiency water heater. This is 3x to 6x the cost of conventional electric hot water heaters.
This strikes me as trial ballon or worse a negotiation initially asking for something totally cra cra so they can fall back and settle for something less crazy. The headlines are claiming that will make heaters cheaper and save consumer money. In the long term hot water heaters are maybe 25% of residential energy use, heat pump heaters are 30% more efficient than simple electric. So savings of 1/3 of a 1/4, but of a huge number. Of course the white elephant in the room is the initial cost for all this. Payback for me is unlikely in my lifetime.
They talk about condenser technology for gas hot water heaters and I am unsure what they are even talking about. Perhaps carbon capture from exhaust?

A few years ago while I was shopping a new clothes dryer I checked out heat pump technology... Today I see heat pump clothes dryers for $1k. Maybe 2x conventional technology. I asked my local appliance repair guy what his experience was fixing them and he said he hasn't seen many (any?) here in nowhere MS. The good news is that my old school (electric ) dryer is still working so I am not going to replace it until it fails.

An old personal musing of mine was to integrate a kitchen hot water source coming from the refrigerator's waste heat, of course not very practical.
Of course we should think about all of this but I worry that gubmint thinks they are masters of new technology, they can't even master the simple math.
