After replacing three water heaters, I meticulously analyzed and finally realized that when purchasing a water heater, you should opt for 5 types and avoid the following 5 types to save money!
1. Choose Slim Water Heaters Over Round Ones
Currently, water heaters primarily come in two designs: slim and round. Slim models are a newer design, while round ones are classic and have been around for a long time. In reality, both designs do not affect functionality.
However, for small bathrooms, round water heaters can be bulky and take up space. In such cases, opt for a slim model, as it is compact and holds more water.
Conversely, if your bathroom is spacious, you might consider a round model, as it is slightly more affordable for the same capacity.
2. Opt for Dual-Tank Over Single-Tank Models
Dual-tank water heaters offer higher heating efficiency and faster heating times but consume more electricity. If your household has multiple members (3–4 people bathing consecutively after work), a dual-tank model is ideal as it heats quickly and holds more water.
However, single-tank models are not necessarily a poor choice. For a family of two, simply adjusting the temperature higher is sufficient. The choice depends on your household’s specific needs and circumstances.
3. Choose Energy Efficiency Level 5, Avoid Lower Levels
Energy efficiency (electricity savings) is crucial when selecting a water heater. Opting for a level 1 energy efficiency model can result in electricity costs over a year that are nearly enough to buy a new water heater compared to level 3 or 4 models.
Especially for those who use hot water frequently, choosing a level 5 energy efficiency model is recommended. Don’t compromise on this for a cheaper, less efficient option.
4. Opt for Slightly Higher Wattage, Avoid Lower Wattage Models
In addition to dual-tank models, wattage significantly impacts a water heater’s heating speed.
For example, a 3300W model heats water very quickly and efficiently. While a 2200W model may seem energy-saving, it takes longer to heat, negating any significant savings.
However, ensure your home’s electrical system, especially the bathroom wiring and circuit breaker, can handle higher wattage to avoid tripping the breaker.
5. Choose Models with Maintenance-Free Magnesium Anodes
Previously, water heaters required magnesium anode replacement every few years, which was costly. However, modern models now feature self-cleaning functions and maintenance-free magnesium anodes.
Opting for a model with a maintenance-free magnesium anode eliminates the need for periodic replacement, saving you time and money on maintenance.
