Conventional Water Heaters in the South San Francisco Area

Conventional water heaters store water in a tank and are available in a variety of gallon capacities. Conventional storage water heater fuel sources include electric or gas energy to maintain the water at a set temperature until a faucet is turned on and water is pulled through the pipe. A conventional electric or gas water heater has a life expectancy of about 11 years. Newer conventional water heaters are more energy efficient than older models, reducing water heating bills by about 7 percent.

Tankless Water Heaters

When it comes to more energy efficient water heaters, tankless water heaters are highly recommended because they heat water only as it is needed. When the tap is turned on, the heater goes to work and supplies continuous hot water. A tankless water heater often requires less space and can hang on a wall, but may require larger gas lines, special venting or additional electric circuits that add to the upfront costs. However, a tankless water heater lasts about 15-20 years and may reduce water heating bills by as much as 30 percent.

Benefits of Tankless Water Heater Installation:

  • Endless hot water supply
  • Energy efficiency
  • Space-saving design
  • Tankless water heaters typically have a longer lifespan, often lasting 20 years
  • Reduced risk of water damage
  • Consistent water temperature
  • Lower operating costs
  • Environmental benefits

Hybrid Heat Pump Water Heater

A hybrid water heater combines conventional tank storage with a heat pump that extracts heat from the air and uses it to help heat the water. A hybrid water heater uses existing water and electrical connections, and can reduce water heating costs by almost 60 percent.

The debate between tankless and traditional water heaters is a comparatively new one. Our skilled plumbers can help you choose the right water heater for your home, and help you avoid common water heater issues. Although tankless water heaters have been introduced in the United States only recently, they’ve been used in Europe and Asia for a couple of decades. There are some inherent advantages of a tankless water heater over the older system.


In storage water heaters, a large volume of water is heated and when partly used, the cold water inflow, along with the remaining hot water, has to be reheated again, using a lot of energy . Traditional water heaters are rated by storage capacity in gallons, recovery rate and first-hour rating.


Tankless water heaters, on the other hand, have an almost infinite capacity for providing hot water. Turn on the heater, and after some time, hot water starts flowing. Since no storage is involved, there is no limit to the flow of hot water, if you stay within the flow rate of four to eight gallons per minute.


A tankless water heater installation is suitable for very large families. A heater with a flow rate of eight gallons per minute can provide hot water for two showers and a large appliance simultaneously.

easier to maintain

A tankless water heater is easier to maintain versus a storage heater. Since water is stored in the tank of a storage heater, there is always a chance of rusting. If the water in your area has excessive iron or other metal compounds, there will be scaling inside the heater. This problem is eliminated with a tankless heater, since no water storage is necessary.

longevity is almost double

Storage water heaters occupy large floor space, which may not be suitable for families living in small apartments. Generally, their capacity ranges from 40 to 120 gallons. Tankless water heaters can be installed on a wall, inside or outside the house, freeing up household space.

Since no rusting or scaling takes place in a tankless water heater, its longevity is almost double that of a storage heater, leading to further cost savings.
