We had some issues with this heater. Firstly, although this model is best used for outdoor activities, we found it is surprisingly susceptible to cold weather, shutting down in freezing temperatures. We also found that the water temperature can be very hit-and-miss, regardless of what settings you choose. Lastly, things seemed to break down irreparably within a year of ownership, which isnt good despite the EZ 101s budget price tag.

How Do Tankless Water Heaters Work? | The Home Depot

Known as on-demand water heaters, tankless water heaters dont store any water. Therefore, they are vastly smaller and more versatile because they require so little space.

A console will heat all the water that you need when you need it. By only heating the amount of water that you need when it is required, a tankless electric water heater can cut out a lot of energy use since the hot water heater wont constantly be heating a tank full of water so that it can be ready at a moments notice.

These water heaters work by piping water through the console, where a heating element heats the water as it passes through. Heating elements are made from nichrome, copper, and other alloys that turn electricity into heat.

Electric Tankless Water Heaters

Electric tankless heaters are very similar to their gas heater counterparts, but they use powerful electric elements for their heat source. Most electric tankless units need three or four 40-amp circuits to provide enough power to heat the water rapidly. Because of this, a 200 Amp main power panel is usually the minimum that will be required. Think that through before you buy a whole-house electricity water heater!

As with gas models, the incoming water temperature will greatly affect their performance and ability to provide a higher volume of hot water . One Consumer Report study said, electric models may be better suited to areas with warmer groundwater, such as the South. Thats an understatement, without question.

Electric models have an Efficiency Rating rather than a Uniform Energy Factor. As with the gas models, this number is helpful when comparing models of the same type.

Summary: Does Home Depot Install Water Heaters For Free

Home Depot does install water heaters but its not for free. They charge between $1,000 $3,000 for a water heater install which includes permits, installation materials, and removal of the old water heater. Water heaters run on either gas or electric and come in two basic designs: tank and tankless. Changing fuel source or switching from a tank to a tankless water heater, or vice versa, can increase installation costs.

The Home Depot works with local licensed and insured plumbers that do the consultation and installation. If you live within 30 miles of a Home Depot store theyll schedule an in-home consultation to help you choose the right water heater based on your budget, fuel source and water usage. Once you select a water heater theyll schedule installation. In some cases they can send someone to meet you and replace the water heating in the same day.

A typical water heater installation takes about 2-3 hours when its a tank to tank switch. If its a conversion from tank to tankless or tankless to tank it takes longer. In my experience this is usually a 4-5 hour job. But a tankless to tankless switch only take about an hour. The reason why tank water heaters take more time to install is the tank. They take a lot of time to fill up with water and drain.

After the new water heater is installed, the plumber will remove and dispose of the old heater.
