Buying Guide: Key Purchase Considerations
What space is available for installation? Storage tanks require more room, while tankless units save space but may demand specific electrical wiring. For small apartments, a compact 12–18 gallon storage heater can address daily needs without complex infrastructure changes.
Do you need instant hot water or a stored supply? Tankless models deliver on‑demand hot water, while storage tanks provide a buffer for peak usage. Consider your typical simultaneous demand (shower plus sink, etc.).
What electrical requirements exist? Many tankless options require dedicated high‑amp circuits (60A or more). Verify panel capacity and local wiring rules before purchase.
How important safety features are? Look for enamel coatings, anti‑scald controls, thermal protections, and IP ratings for moisture resilience in bathrooms or kitchens.
Are you prioritizing energy efficiency? Tankless models generally avoid standby losses and can trim energy costs, but upfront installation complexity may offset long‑term savings.
