What to Be Aware Of !!!

Before you buy a hot water heater from any of these brands. There are a few things to look out for and we have highlighted some below;


Water heater warranties normally range from three to twelve years. Though longer-warranty models cost a little more. We’ve discovered that they contain larger elements or burners that can speed up water heating and thicker insulation for reducing heat loss. So we advise you choose a water heater that comes with the longest guarantee.
Scale-prevention devices: Some manufactures advertise water whirling characteristics that are meant to reduce mineral scale formation at the bottom of the tank. Although scale can affect the life of the heating element, you don’t need to spend a lot of money to have a long-lasting water heater. Simply seek one that comes with a 12-year warranty and a longer or thicker element.

Empty valves (brass vs. plastic) are located around the base of the water heater and allow a garden hose to drain the heater. Drain valves made of brass are more durable than those made of plastic. Glass-lined tanks are made to prevent corrosion.

Digital displays: These aid in the monitoring of levels and the customization of operations. You can select a vacation mode on some electric/heat pump hybrid water heaters to use only the heat pump for improved efficiency while you’re gone. Solar water heater displays frequently show tank and collector temperatures, as well as pressure readings and other data.
