Non-Condensing Water Heaters
Non-condensing water heaters are gas units that do not condense exhaust gases to capture extra heat. They typically operate below 90% efficiency because heat is vented outdoors with combustion gases. These heaters are simpler in design, often less expensive, and easier to install, but can have higher operating costs compared to condensing models.

FAQ
Do non-condensing water heaters need special venting?
They use standard metal venting, but sizing and installation must meet code.
Are non-condensing water heaters cheaper to install?
Usually yes, especially when compatible venting already exists.
Can I upgrade to a condensing model later?
Yes, but it may require venting changes and a condensate drain.
