Tankless water heaters, which heat water on demand rather than store it, are more compact and energy-efficient than traditional water heaters. Is a tankless water heater right for your home? It has many advantages, especially if youโ€™d like hot water when needed rather than it being constantly heated and reheated in a tank.

Tankless Water Heater Pros

A tankless system starts working when you open the hot water tap. It shuts off when thereโ€™s no longer a demand for hot water. The advantages of this include:

  • Hot water is instantly available: You can get a continuous supply of hot water; as water flows into the system, burners produce the heat needed depending on the incoming waterโ€™s temperature. The supply isnโ€™t limited to a storage tankโ€™s capacity (which ranges from 30 to 60 gallons). Taking a shower or bath, rinsing the dishes, or washing clothes is easier since thereโ€™s always hot water.
  • Flexible installation: Tankless hot water heaters take up much less space (the size of a carry-on suitcase). You can install them just about anywhere, even inside a closet. The water heater can supply your entire home with hot water or be installed for use with individual appliances and fixtures, such as a single shower or sink.
  • Energy savings: Traditional hot water heaters use a lot of energy to keep a full tank of water heated, which can drive up your energy bills. With a tankless system, you can save up to 40% in energy costs related to water heating. Thatโ€™s because they only heat water when necessary.
  • Longevity: A tankless water heater can last as long as 20 years before breaking down or failing. On the other hand, a traditional system may last a decade if youโ€™re lucky. This can delay the cost of replacement especially if you plan to own your home long-term.
  • Cleaner water: The water you get on-demand is always fresh and clean. Traditional water heaters are prone to rust and scale build-up in the tank. This is the same water you drink and use to bathe and wash the dishes.

Tankless Water Heater Cons

Potential cons of a tankless water heater include:

  • Limited output: A tankless system has a lower water output, so it is limited in terms of serving multiple sources at once. Running multiple faucets, along with showers, dishwashers, and washing machines simultaneously can overload the unit. You might not get hot water everywhere when running all these together.
  • Instantaneous energy spikes: There are times when traditional water heaters use less energy, as hot water is in reserve. The energy needed by a tankless system to start producing hot water is greater. High-powered burners do consume a bit of energy, so check the specifications of the unit youโ€™re considering for the sake of comparison.
  • High installation costs: Upfront installation costs are more for a tankless water heater. You might also need to install special vent systems and a larger diameter gas pipe. However, monthly energy bill savings may offset the additional installation costs, depending on the system you purchase and how much you pay each month.
