Recirculation Systems for Tankless Heaters in Kodiak
Tankless heaters can take a few extra seconds to deliver hot water to distant fixtures.

We design the system to suit your plumbing layout and usage patterns.
Tank to Tankless Conversions in Kodiak
Converting from a tank requires more than swapping units. A 40 gallon tank heater uses roughly 40,000 BTU, while a whole-home tankless unit may need up to 199,000 BTU, so the gas line often needs to be upsized. Venting changes from a metal flue to PVC or stainless, and the unit moves to a wall location. We remove and dispose of your old tank and patch the old flue penetration.
