And what about heating water?

A heat pump water heater is pretty great, if my basement ever gets too hot I run the dishwasher or take a shower and the water heater cools things down nicely. In winter I close the door and vent to the utility room and it doesn't hurt the heating very much. It's smaller than my previous gas water heater but it lasts significantly longer and heats up faster if you do end up using all the hot water. My house of 4 uses about 50kWh of hot water a month, which works out to about 5bucks a month. I've messed with it a bit so it runs mostly during off peak hours.

I replaced my water heater, got a heatpump and improved insulation at around the same time (through the greener homes loan program) and on the whole saved about 50bucks a month overall, and will save another 30 when I cap off the gas pipe and get to stop paying all the bullshit fees for just having it connected. I live in southern Ontario, away from the lakes, so -30 - 30 weather typically. (All this week has been 40+ though, wonder why...........).

Oh and fwiw, I would take my current induction stovetop over a gas stove anyway, much more consistent, easier to clean and heats up faster, and doesn't heat up the whole house to run.
