Yes, when it is sized correctly. Tankless units heat water on demand, so the limit is flow rate rather than tank capacity. We look at how many showers, faucets and appliances you run at the same time and how cold your incoming water gets, which matters during St. Louis winters, then match a unit that handles your household’s peak use.
A tankless unit mounts on the wall and is roughly the size of a carry on suitcase, while a traditional tank takes up several square feet of floor space. Homeowners often use the reclaimed room in a utility closet, basement or garage for storage. We plan the location around venting, gas or electrical needs and easy access for future service.
It usually involves more than a simple swap. Depending on your home, a tankless unit may need a larger gas line, new venting or electrical upgrades, along with changes to the water connections. We assess your existing setup before installation so you know what is involved, then handle the connections, test flow and safety, and show you how the system works.
Yes. Minerals in the water can build up inside the heat exchanger over time, so most manufacturers recommend descaling the unit about once a year. Homes with hard water may need it more often. Cleaning the inlet filter and checking the venting also help the unit run efficiently. Routine care keeps your hot water consistent and protects the life of the equipment.
Most do not. Even gas tankless units rely on electricity to run the controls, igniter and venting fan, so they stop heating when the power goes out. A traditional gas tank may keep supplying stored hot water for a while. If outages are a concern for your home, we can talk through your options while planning the installation.
