Converting From a Tank to Tankless? Here's What to Expect

Switching from a traditional tank-style water heater to a tankless system comes with a few key considerations:

  1. Gas Line Sizing – Tankless water heaters require more BTUs than standard tanks. In many cases, your existing gas line will need to be upsized. Our team will inspect and upgrade your gas line as needed to ensure safe, proper operation.

  2. Venting Requirements – Unlike tank systems, tankless units require new PVC venting that exits directly through an exterior wall or roof. This venting must be installed properly to meet manufacturer specifications and ensure safe operation. We take care of this as part of the installation process.
