Monitoring Electricity Costs.

My difference with and without a tank was pretty minimal compared to say my computer lol.

I pay about an additional 15 bucks a month so far in the summer (heater not running much), so 2xT5 and pumps make up that. Haven't seen the price in the winter but it will probably be closer to 30.

 

I have gas water heaters(yes...2) and I WISH oh wish I had electric. You'd think my water heaters were running 2 small block chevy's as much as my gas bill is. Electric is a lot too because I run the AC from about 9AM to 10PM(undersized unit, vaulted ceilings, and it's really freakin' HOT!).

 

Can anyone with a tankless waterheater tell us how their bill changed?

 

I have a combination commericial sized tankless hot water heater (required as my HVAC furnace relies on hot water as a heat source), and a solar hot water tank.

So far this summer, 90-95% of my hot water has been free. Last winter, my gas bill for hot water dropped by an average of 60-80% a month (depending on how much sunlight we got each day).
