Tankless Water Heater Gas Line Size

If you’re considering upgrading to a tankless water heater, one of the first questions you might have is what size gas line you need. The answer depends on a few factors, including the model of tankless water heater you choose and the number of appliances you have that will be using hot water.

Generally speaking, you’ll need a gas line that can deliver between 3-5 gallons of water per minute. That might seem like a lot, but it’s actually not much different than the flow rate of a typical faucet.

If you have a home with multiple bathrooms and appliances that use hot water, you might need a higher flow rate. In that case, you might need a gas line that can deliver up to 10 gallons per minute.

No matter what size gas line you need, it’s important to have a professional installer do the work. This is not a job for a DIYer, as even a small mistake can be dangerous. Once your new tankless water heater is up and running, you’ll enjoy an endless supply of hot water!

Finally, you’ll need to consider the size of your home. If you have a large home with multiple bathrooms, you’ll need a larger gas line than someone with a small home. That’s because a tankless water heater will have to provide hot water to multiple fixtures at the same time.
