Is a Tankless Water Heater Right for Your Brooklyn Home?

The New Year is here, and it might be time to consider whether a tankless water heater would be a good fit for your Brooklyn household.

Tankless heaters provide hot water on demand. They are also known as instantaneous or demand-type water heaters. Instead of being kept hot in a tank, water is directly heated as it flows through the unit. This is accomplished by either a gas burner or an electric element.

The experts at Petri Plumbing are glad to discuss the advantages that converting from conventional water heaters to tankless heaters can offer our Brooklyn neighbors.

Advantages of tankless water heaters

According to, households that use 41 gallons or less of hot water per day can save significant amounts of energy by installing tankless water heaters. Because less energy is spent keeping stored water hot, they can be 24 percent–34 percent more energy efficient than conventional types. A typical family can save $100 or more per year, according to ENERGY STAR® estimates.


The only limiting factor to tankless water heater capacity is an average flow rate of 2-5 gallons per minute. Unless multiple hot water appliances are being used at the same time, this can meet normal household needs. suggests installing multiple tankless heaters can provide the necessary capacity to meet demand for hot water in large households:

You can install two or more tankless water heaters, connected in parallel for simultaneous demands of hot water. You can also install separate tankless water heaters for appliances — such as a clothes washer or dishwasher — that use a lot of hot water in your home.

Installing a tankless water heater at each hot water outlet can reduce energy costs for households that use large amounts of hot water, around 86 gallons per day, by 27 to 50 percent.
