BUYING GUIDE
The quest for endless hot water has led many homeowners to consider the investment in a tankless water heater. Unlike traditional water heaters, which store and heat water in a large tank, tankless models heat water on-demand, offering the allure of infinite hot water and improved energy efficiency. However, with numerous options available in terms of size, fuel type, and features, choosing the best tankless water heater can be overwhelming. This guide will provide you with the critical factors to consider, helping you make an informed choice tailored to your needs.
1. Fuel Type:
Tankless water heaters can be powered by electricity, natural gas, or propane. Your choice will depend on what’s available in your area and your preferences for operational costs.
2. Size and Flow Rate:
Consider your household’s hot water needs in gallons per minute (GPM) to select the appropriate size. More significant needs require a unit with a higher flow rate.
3. Energy Efficiency:
Check the unit’s Energy Factor (EF) rating. The higher the rating, the more efficient the water heater is, which could translate to lower utility bills.
4. Installation Requirements:
Tankless water heaters often have specific electrical or gas-line requirements. Make sure to check these details and factor in the cost of potential upgrades.
5. Temperature Control:
Some advanced models allow you to set the output water temperature precisely, providing more comfort and safety.
6. Ventilation:
Gas and propane models require proper ventilation for safety. This could be a significant factor in installation costs.
7. Build Quality:
Opt for models that feature robust construction and quality materials to ensure longevity and reliable performance.
8. Brand Reputation:
Brands like Rinnai, Rheem, and EcoSmart have established reputations for reliability and performance in the tankless water heater market.
9. Warranty:
A solid warranty can offer peace of mind, safeguarding your investment in the long term.
10. Digital Displays:
Some models come equipped with digital displays for easier monitoring and control over the system.
11. Outdoor vs. Indoor:
Choose between outdoor and indoor models depending on your space and installation capabilities.
12. Water Hardness:
If you live in an area with hard water, consider a unit that is designed to handle it or invest in a water softener.
13. Portability:
There are portable tankless water heaters designed for uses like camping or outdoor showers. These are generally smaller and less powerful but offer great flexibility.
14. Safety Features:
Look for safety functions like overheat protection and secure venting systems to ensure safe operation.
15. Customer Reviews:
Always read customer reviews to get an understanding of the product’s performance, reliability, and any issues that may not be apparent from the product description.
