An old electric hot water heater can have an amazing amount of lime and debris that insulates the heating elements and prevents heat transfer from the heating elements to the water. I changed an 18 year old heater only because it started to leak. My electric bill dropped considerably with just a new standard electric water heater. When I drained the old one for removal it was still extremely heavy to move with a hand truck. When I finally wrestled it outside and reopened the drain at least 20 gallons of chalky white water came out. I never thought about flushing it annually before that, but I do now.

I just replaced my 1970s electric hot water heater with a hybrid. According to the Energy sticker on them, it's supposed to use $150 of electric per year vs $450 for a similar sized plain electric heater. I'll bet that number is based on heat-pump-only mode, but that's ok, because once the heater came up to temp, I manually switched it to heat pump mode so it will never use the coils.

Took a shower and it took about 3 hours to come back up to temp on the heat pump. That's ok, I don't use hot water much and I'm the only user, so time to recover is just not as important as cost savings. I was spending a ton of money just keeping the tank hot for no reason.

We love our Tank-less on demand water heater.
It uses propane.
