I'm exploring options for tankless water heaters, specifically the Navien NPEA2 model. I've received some quotes but noticed that many plumbers charge around $100 just to come out and provide a quote. I've found the unit online ranging from $1800 to $2400, but there are posts suggesting total costs could reach up to $10,000. I'm trying to budget—if this installation is closer to $10k, I might skip the quotes and just install a traditional tank heater myself. On the flip side, if it's more around $3k to $5k, it might be worth getting a few quotes. It's worth noting I currently have a gas hot water tank and believe my gas service is adequate, but I'm concerned about potential venting and modification costs. Any insights on what install costs typically look like would be really helpful!

Installation costs can vary a lot! A tankless water heater needs a lot more gas than a standard tank, so you might have to upgrade your gas supply lines or even the gas main. Plus, the venting can get tricky and might add to your costs. On a side note, I've read that tankless heaters aren't eco-friendly due to methane emissions when they switch on and off. You might want to consider an electric heat pump water heater instead for an environmentally conscious choice.
I installed a tankless heater in my basement for about $3,500 and it's been a fantastic choice! I’d definitely recommend it if you're considering an upgrade.
From what I've gathered, the tank prices usually hover around $2,000 max for tankless models. Installation in my area (AL) typically runs between $4,000 to $6,000, so keep that in mind when budgeting!
Check out the Rinnai tankless heaters at Home Depot for real prices! Usually, any price above that is mostly for installation costs.
Make sure to check your gas supply; it's often not sufficient for tankless heaters unless you're super close to your gas meter. Venting may also require completely new setups. If the old venting setup doesn’t meet the new requirements, you might have to shell out more cash for upgrades. Some kits are available that let you use the old vent as a sleeve for the new vent, if it’s a straight shot.
