Buying Guide
- Installation type: Indoor vs. outdoor units affect venting, space, and noise considerations. Outdoor units usually require weatherproofing and may include remote controls for indoor operation.
- Flow rate (GPM) and BTU: Choose a model that meets peak demand. Tankless units are rated by GPM; storage models are size-rated by gallons. Higher BTU usually means faster heating and better performance during simultaneous usage.
- Temperature control and safety: Look for flame failure devices, anti-freeze protection, overheating protection, and digital displays for precise adjustments.
- Durability and materials: Stainless steel construction and corrosion-resistant coatings extend service life. Copper heat exchangers reduce heat loss.
- Ventilation and code compliance: Ensure proper venting and compliance with local codes for natural gas installations. Some models require professional installation and periodic inspections.
- Warranty and service: Evaluate warranty length and coverage for parts, labor, and the heat exchanger. Local service availability can influence long-term reliability.
- Space and retrofit considerations: Tankless units save space but may require specific clearance and mounting. Traditional 30-gallon tanks offer simplicity for higher simultaneous demand but occupy more space.
- Energy efficiency: Models with precise temperature control and low standby losses save energy. Compare annual fuel utilization efficiency (AFUE) ratings where available.
- Maintenance needs: Some units include self-diagnostic features and simple filter or vent inspections, reducing maintenance hassles over time.
