Your On Demand Water Heater can last 20 years or longer!


tankless on demand water heatersTankless or on-demand water heaters provide hot water instantly. Water is heated when needed, which eliminates the need for a storage tank. Additionally, the loss of water is reduced because you're not waiting for water to heat up. Another benefit is the life expectancy of an on-demand water heater, it’s 20 years. In comparison, a storage tank heater can last 8 to 12 years. Additional benefits are the elimination of tank leaks.

Hot Water When You Want It

Your tankless heater starts to work when the hot water is turned on and cold water is drawn through the pipe into the unit. Inside the unit is a gas burner or an electric heating element, depending on what your home uses. Based on the size of your on-demand water heater, it can produce 2 - 5 gallons of hot water per minute.  The size of your water heater will depend on your family size, how often showers are taken, along with appliance usage. At Big B's Plumbing, we have tankless on-demand water heater technicians that will help you calculate the proper size of the water heater that's right for your family and home.

Save BIG on Tankless On-Demand Water Heaters

Your on-demand water heaters are usually installed where the storage heater previously existed, taking up 75% less space. According to the Environmental Protection Agency (EPA), Energy Star certified on-demand tankless water heaters could save a consumer up to $1800 over the lifetime of the product compared to a storage tank heater. The Energy Star label ensures the consumer that the product they are purchasing has been tested for energy efficiency, emissions, pollutants, and greenhouse gases.
