Tankless Water Heater Installations:

Tankless water heaters provide continuous hot water, ideal for large families or homes with high hot water demands. If you have a soaking tub or spa system, a tankless system is often a suitable choice. Most people end up upgrading their water heater when they are dissatisfied with the amount of hot water their current water heater is providing. Tankless heaters are assessed based on flow rate rather than gallon capacity, recovery rate, and first-hour rating, unlike traditional storage tanks. With the tankless water heater, hot water is always available, as long as the flow rate is within the tankless heaters maximum flow rate.

It’s essential to note that tankless units don’t offer instant hot water, as it takes time for hot water to travel from the unit to the destination. For instant hot water, inquire about recirculation systems, which our experts can install based on your plumbing configuration.

Energy-Savings:

The most efficient tankless heaters boast 92% to 95% efficiency, far surpassing traditional gas storage tanks with a maximum efficiency of 62%. Nowadays, tankless units typically exceed 80% energy efficiency, saving the most energy by not constantly re-heating water in the storage tank. What these numbers mean is that these tankless water heaters can attain an impressive thermal efficiency rating of 92%-95%, signifying that virtually all of the energy utilized in the heating process is converted into heat.

Space Efficiency:

Tankless water heaters are significantly smaller than their traditional counterpart. These tankless water heaters are about the size of a small shelf that gets mounted on the wall. Because these water heaters are mounted on the wall and are small, they have cleaned up many closets and garages in the Millbrae area.

Tankless Water Heater Sizing:

In sizing your tankless water heater, we emphasize flow rate as the most crucial factor. Tankless units heat water on demand, unlike traditional storage tanks. The size is determined by per-minute flow rate, not gallon capacity. Most manufacturers offer models with flow rates ranging from four to eight gallons per minute. For single-family homes with two or more bathrooms, we recommend installing a six to eight-gallon per minute unit, designed to handle multiple applications simultaneously. Larger homes or commercial applications may require multiple tankless units installed in series.
