Eccotemp water heaters are sold through specialty channels reflecting the tankless and point-of-use market — fewer big-box presence than tank water heaters, more emphasis on specialty plumbing supply, online retailers, and direct.

Pricing expectations
Eccotemp pricing varies dramatically by application:
- Point-of-use single-fixture electric: $80–$300
- Whole-house residential electric tankless: $500–$1,500
- Residential propane tankless: $400–$1,200 (portable to indoor)
- Commercial single-fixture: $300–$800
- Commercial whole-system tankless: $1,500–$5,000+
What to verify before purchase
- Electrical capacity at install location (whole-house electric tankless can require 100–150A!)
- Water flow rate and pressure requirements
- Mounting clearance and venting requirements (gas models)
- Temperature rise capability at your location's incoming water temperature
- Compliance with local code (some jurisdictions require ETL/UL listing)
Installation considerations
Eccotemp water heater installation requires specific skills:
- Electric tankless: high-amperage circuit installation often requires panel upgrade (200A+ panel for some whole-house electrical tankless)
- Gas tankless: sealed combustion venting through wall or roof, specific gas line sizing
- Point-of-use: simpler — typically dedicated 120V or 240V circuit, freshwater line connection
Common purchase mistakes
- Buying undersized electric tankless without panel upgrade evaluation
- Selecting gas tankless without verifying gas line capacity (often requires upgrade to 3/4" or larger)
- Choosing single-fixture point-of-use for whole-house applications (insufficient capacity)
- Forgetting that high water hardness will dramatically increase descaling frequency and reduce lifespan
