Frequently Asked Questions

Just like traditional water heaters, tankless water heaters provide your home with hot water. The main difference is traditional water heaters store hot water in a water tank while tankless systems heat the water on-demand. In doing so, tankless water heaters provide a consistent and near-endless supply of hot water.

Tankless water heaters require regular servicing, just like traditional water heaters. A maintenance appointment once per year allows us to make sure your system is working efficiently. It also gives us the opportunity to flush your system to remove any minerals or sediment that have built up over time.

Any type of home can benefit from a tankless water heater, but they’re especially beneficial in homes that don’t have a lot of space. Tankless water heaters need less space and can also provide energy savings, as they only heat water that is being used. Some tankless systems can also last longer and provide cleaner water.

The estimated installation time is 3 to 5 hours for most homes, but there are a few different considerations that impact how long it will take. Whether your existing water heater is tankless will impact installation time. Your water heater’s location in your home can also impact installation time, depending on how accessible it is.

You can get your home ready for installation by removing any belongings or unnecessary items from the areas we’ll be working in. In most homes, this includes emptying out your furnace room and creating a clear pathway through your home. In doing this, you can help us install your new unit as efficiently as possible.
