Cost InfoKasa Team

Water heater replacement typically runs $1,200–$3,500 installed, with tank models (Rheem Performance Plus, $800–$1,200 unit cost) at the lower end and tankless units (Navien NPE-240A, $1,800–$2,400 unit cost) commanding premiums due to higher efficiency and longer lifespan. Budget an additional $400–$800 for labor, permits, and any necessary venting or gas line upgrades.

WarningKasa Team

Delaying replacement beyond 10–12 years significantly increases leak risk, which can cause catastrophic water damage to flooring and substructure before warning signs appear; a failed water heater inside a finished basement or attic can cost $5,000+ in remediation versus $2,000–$3,000 for proactive replacement. Neglecting annual flush maintenance accelerates sediment buildup, reducing efficiency and hastening failure.

Tool RecKasa Team

A non-contact thermal imaging camera like the FLIR ONE Pro LT ($200–$250) allows homeowners to verify uneven heating patterns and pinpoint temperature stratification in existing tanks, confirming whether replacement is justified before calling a plumber and preventing misdiagnosis as a performance problem. This eliminates guesswork during the evaluation phase. ---
