Frequently Asked Questions

Just like the name implies, tankless water heaters provide your home with hot water without needing a storage tank. They do this by heating the water on-demand, rather than storing hot water like a conventional water heater. This means tankless water heaters can provide a constant supply of hot water.

Tankless water heaters require yearly maintenance, similar to a furnace or air conditioning unit. Annual maintenance is an opportunity for a tune-up to keep your unit running its best. One other thing tankless water heaters may require are flushes to eliminate the buildup of sediment and minerals.

Any home can benefit from a tankless water heater, but they work especially well in homes that don’t have a lot of space. Tankless water heaters are a lot more compact and they have the added bonus of energy savings over time, as they only heat the water you’re actually using. Tankless units can also last longer and keep your water cleaner.

How long installation takes will vary from home to home, but most tankless water heater installations will be 3 to 5 hours. Whether you’re switching from a traditional water heater to a tankless one can increase installation time. Its location in your home can also influence how the installation will take.

You should prepare your home for installation by making sure the areas we will be working in are clear. When you take the time to remove any clutter from the areas we’ll be working in, it makes our job safer and more efficient. For tankless water heater installation, you should clear your furnace room and a path through your home.
