We pay 21 cents total per kwh for electric in Maryland. Not sure what our natural gas costs are. Heat pumps don't always operate at max efficiency.[/quote]

On the website below the current price for MD is listed as 17 cents:

Tell that to my pepco bill lol[/quote]

There might be a variety of charges on the bill above and beyond the hourly rate. To compare electricity vs gas unit prices, we need to treat those charges symmetrically, so that we don't inadvertently bias the results. Probably, 17 cents is indeed the unit rate for electricity if you strip away the various extra charges. [/quote]

All the "extra charges" except an $8 customer charge are based on the amount of electricity we used so yes, they are relevant for comparing costs. One of those for example is the Montgomery County energy tax which is a little over 1 cent per kwh. The rates also seem to change - there are summer rates and winter rates for example. If you take out the $8 customer charge, 20 cents is our average over the last 6 months.

The main reason we won't be getting a heat pump water heater is because it would cool our basement in the winter. We do have an air source heat pump as part of our HVAC system.[/quote]

My point is that there are also extra charges on one's gas bill. So we shouldn't ignore the extra charges on a gas bill and include them on an electrical bill. We should use a symmetric approach so that the resulting unit costs are apples to apples.[/quote]
