Well, I am sure you know that 6-10 feet under the ground it stays a regular 50-60 which is above the use temps. If you throw it into a furnace or washer/dryer room, that is free heat. And the ground is a huge tank of that heat (it's why it is hard to heat basements sometimes.

Most people don't have heating in their basements. So it really is negligible.

But I have already included the full cost of running it purely as a resistance heater for 8 months and it costs less.

The thing is that it doesn't take a lot of heat to compress down in a heat pump, even if it decreases the resistance usage by half over the whole year, we are at my second number.

If a house heat pump can get warmth for a home out of 40 degrees without using resistance heating, then a heat pump water pump can get it out of a 50 degree basement

I appreciate your well done calculations. The only missing link is the heat energy heat pump water heaters collect is costing money from another source in colder climates, such as ours. The BTU’s taken in are collected from that generated by our heating systems in all but a few months of the year. While these do lower the electricity used by the unit themselves, unless the place they are located has excess heat such as, for example, that from a greenhouse that experiences solar heat gain, they are making another system in our homes run harder or longer to generate the heat they are collecting. Heat Pump HVAC systems benefit from being able to move very large amounts of air in the outdoors so they represent huge savings now since newer versions can overcome their balance points at very low temperatures, but in northern areas the balance points of tanked heat pump water heaters can only be overcome by being in our heated spaces indoors and those spaces need to have a high volume of air available for their fans to move enough air to collect heat from to not need the electric element.

So, your electric bill is lower, but if it is collecting that much heat in your basement enough to overcome its balance point on a consistent enough run rate to save ‘big bucks’, where is the heat energy coming from that gets to the basement for it to extract when it’s 30 degrees outside?

Your floors are providing the heat via your furnace heating the house. If you read my post I’m not giving hard numbers or saying they don’t have a use case, but the movement of heat energy is very complicated, so much so my work is done for the Department of Energy, ASHREA and ACCA and is only accepted when it’s corroborated with three other engineers work. If your loosing that much heat energy from the buildings thermal envelope, your biggest savings are insulating your house, in which case once you would, your heat pump water heater that has a high balance point of close to 50° would end up running almost entirely on its electric element.

Duh. I totally missed that they swapped out electric for electric. My house is gas so whenever I think about adding electric I think about the 220v line.

I have 200 amp service but it's unclear at what point do you need a 2nd box if you concert a lot of gas appliances to electric or add a plug in car.

And as you said I know physical box space makes a difference too.

Some comments from the petition they have asking for people to support this lawsuit are straight off the M4L playbook, with variations of “it’s indoctrination, kids should just learn to read and write, they’re teachers not counselors, I will decide what values my child learns” etc.

If you’re inclined to read more for educational purposes only, you can find their petition on change.org.

Personally if you’re that opposed to having thoughtful, kind and inclusive children then homeschool them or pay for private school.

Based on this comment, presumably they did. But even if they didn't, adding a 240V outlet is not very expensive as long as its location has reasonable access to the breaker panel and you have available capacity. If you don't have available capacity then you really want to consider upgrading that in the semi-near future regardless because you will absolutely want it.

As shitty as it is for the workers if that's the contract language, then that's how it is. I'm a union worker, and we are not allowed to strike per our contract which means if my office were going to act like we were; we would have to use vacation/break/outside of work hours to picket.

Regardless of what this guy says, I installed a HP hot water heater in my basement this past summer and I'm saving big bucks. My previous electric water heater was probably using 30-40% of my monthly electric bill. With the HP, my electric bills have probably halved (even considering recent price hikes). Sure, it will be a few years before I break even, but I think it is worth it, especially with the price of electricity increasing as it has been.
