1. Capacity and Size
When buying a new water heater, it's crucial to consider the capacity and size of the unit.
- A larger capacity means you'll need less frequent refills and lower fuel bills.
 - A smaller capacity requires more frequent refills and higher fuel bills.
 
2. Energy Efficiency
Look for a water heater with high energy efficiency ratings, such as the ENERGY STAR label.
- A more efficient water heater uses less energy to heat your water, saving you money on your utility bills.
 - Check if the unit has any special features like solar panels or advanced heating technologies that can improve its efficiency.
 
3. Maintenance and Repair
A reliable water heater is one that's easy to maintain and repair, reducing the risk of costly breakdowns.
- A good water heater should have a user-friendly interface for easy monitoring and maintenance.
 - Consider a water heater with automatic shut-off and overheat protection to prevent accidents.
 
4. Safety Features
A safe and reliable water heater is essential for your plumbing system, preventing accidents and injuries.
- Adequate insulation and weatherstripping around the water heater can prevent water from leaking into the surrounding area.
 - A water heater with built-in safety features like pressure relief valves or thermostatic mixing valves can help protect your plumbing system.
 
5. Warranty and Support
a reputable water heater manufacturer will stand behind its product, offering a comprehensive warranty and dedicated customer support.
- A typical 10-year warranty is a good starting point, but some manufacturers may offer extended warranties or additional perks like maintenance discounts.
 - Research the company's reputation online, reading reviews and checking for any recalls or safety concerns.
