Building a 4-bedroom, 3-bath 2450 sq ft home in Broussard. Our builder said they have been installing electric water heaters because of an issue with the gas hookups in Broussard, but gas is being supplied to the range/oven and outside kitchen. He said something to the effect that the water heaters were “popping” with the gas hookups. We are a family of 6, and every night there are 3 separate baths (my 2 younger boys share a bath, my older daughter has her own, and my wife), and I take a shower. Baby is bathed every night, my water usage is minimal.

We wash clothes/towels every day and run the dishwasher daily. Should I press to install the gas hookup, go tankless, or just settle for the electric water heater? We currently have a gas water heater and never ran out of hot water. My quick, rough calculations tell me that I will be spending about $20/month more for an electric water heater vs gas.

Nice to have hot water during power outages during hurricanes - being from Broussard you would be familiar with that - you’ll have hot water with a tank gas water heater. It was nice to take hot showers for the 4 days I was without power during Ida.

Your house is nearly identical in sq footage to mine, 4 bed, 3 full baths, 2,460 sq ft living area. I have 2 tank natural gas water heaters, 50 gal for bedroom wing and 40 gal for rest of house (kitchen, laundry, a 3rd full bath).

That said I’ll be replacing both water heaters in a couple months b/c of age. My BIL is a master plumber and will do the work as soon as the attic cools in a couple or 3 months. This what he has suggested and I will go with. 40 gal tank gas water heater will be replaced with another 40 gal tank water heater. The 50 gal tank water heater that supplies the main bedroom wing room (2 bathrooms) will be replaced with a Navien tankless gas recirculating water heater that operates off a standard 1/2 inch gas line and doesn’t need to be up-sized to a 3/4 inch gas line.

Anyway - some food for thought for you to consider. Can’t comment on problems with gas hookups in Broussard - that sounds strange.

I had a gas tankless water heater at my last house and loved it. It is more money up front, but less to run for unlimited water supply.

I would only have an electric heater if I absolutely couldn’t have gas. I like my tankless. I have tanked as well in another part of the house. I would at least have a gas line run to that area in the building phase, but I would probably install tankless.

I have a gas, tankless water heater. I could shower for 2 weeks, should I desire to. During power outages, generator provides spark.

Only issues is when water line has low water pressure, but I’d suppose tank water heaters have issues then also…

It sounds like whom ever is hooking up the gas doesn’t have the correct gas regulator. I would go with tankless

New construction, absolutely go with tankless. We just had to replace our traditional water heater and looked into tankless. It was going to be a lot of coin to retrofit it into our 1991 constructed home. I kind of wish I'd just bit the bullet now though. We went with a 50 gallon gas one, and it's been giving us problems. Rheem at some point turned into a shite company with awful customer service and reliability.

We building in Broussard too. Plan to break ground next month near Bayou Tortue. We are going with two tanked water heaters. One builder wanted tankless. My research in price and the product led me back to tanks. I have not heard about gas hook up issues.
