I live in Denver and have two average showers, an average dishwasher, and an average clothing washing machine (in a two-story house). My wife and two elementary-school kids are currently using a 15-year old tank water heater and would like to replace it.
The existing heater is in the basement and sits on the floor near an exterior wall. It is powered by natural gas, so there is some venting in-place.
I have been looking at Home Depot and Amazon, and I'm just not sure if I can get away with a tankless water heater with my budget. I wonder if a water heater like one of the following would work well for me.
As you can see, I am looking at electric, but should I be sticking with natural gas (I think I have space in my breaker box, for additional breakers and will verify soon)? Are these example water heaters reasonable, or do I need to go up in price, given that I expect to keep the water temp at 120F? What am I not taking into consideration?
