what would you recommend for a home with no gas, only electric? We currently have one 40 gallon water heater and its not enough. The water heater is not that old, and it works fine. Should we just replace it with a bigger one? or add another 40 inline?
I've seen some pretty heavy electric tankless heaters that can do two showers at a time. Or you can upgrade to a larger water heater. I wouldn't put a second one in.
1. Instead of a high gas bill you will have a high electric bill.
2. I'm not an electrition but, what kind of service do you have to your house and what size breaker does the heater have? If you don't have a 150 or really a 200 amp main forget it. Two water heaters drawing 40-50 amps each, then you have an electric oven as well with 40-50 amps, you're comming close to tripping that 150 amp main breaker. Turn on few lights and TVs and you're there, turn on the dryer and it's going for sure. A 200amp could probably handle it if you have central air or a dryer, not both though.
