Important features of water heaters

Warranty: You will usually pay more for a water heater with a more extended warranty, but it may be worth the investment. You’ll want as long of warranty coverage as possible because these appliances typically only last 3-12 years.

Anti-scale devices: You can use a machine to reduce mineral buildup in the tank. It works by swirling the water, and you’ll see less of it within the tank. A 12-year warranty can ensure a long lifespan for your water heater. When looking, search for models with thicker or longer heating elements that typically come with 12 years or more warranties.

Brass vs. plastic drain valves: If you want a garden hose to drain quickly, you’ll want to invest in a brass water heater drain. It’s more durable than plastic.

Glass-lined water tanks: They’re designed to offer a corrosion-resistant surface.

Digital displays: Digital displays can monitor water levels and help you customize operations. Some electric/heat pump hybrid water heaters allow you to use a vacation mode that only uses the heat pump for added efficiency if you’re away from home. The system also displays tank and collector temperatures on the screen and other readings.
