Frequently Asked Questions

Tankless water heaters work similarly to traditional water heaters, except they do not store the hot water in a storage tank. Instead, tankless water heaters heat your water on-demand every time you turn on the tap, providing your home with a constant and unlimited supply of hot water.

Tankless water heaters need similar maintenance to traditional water heaters, so you can expect to schedule a maintenance appointment once per year. The main difference is that the maintenance may include flushing of your tankless water heater. We do this to remove any sediment or mineral buildup.

All homes can benefit from a tankless water heater, but they are especially beneficial in homes that don’t have space for a large hot water tank. Tankless water heaters not only take up less space, but they also provide energy savings as they only heat the water you use. Some tankless water heaters also last longer and provide cleaner water.

The standard time estimate for installation is 3 to 5 hours, but installation times will be different for every home. If you are switching from a traditional water heater to a tankless unit, installation time could be impacted. Your water heater’s location in your home can also increase or decrease installation time, depending on how accessible it is.

You should prepare your home by clearing any work areas before we arrive. This means making a path through your home and removing any unnecessary items from your furnace room. By removing any clutter you not only make our job safer, but you also help the installation go as quickly as possible.
