Pros and Cons of Tankless Water Heaters

Tankless water heaters, or demand-type water heaters, supply hot water to your home only as needed, as opposed to traditional water heaters which store hot water in a tank, as the name would suggest. Tankless water heaters do not result in standby energy losses like a traditional water heater does, which saves you money. 

How Tankless Water Heaters Work

Rather than using a storage tank, tankless water heaters work by providing water to your home only when needed. When a hot water tap or shower is turned on, cold water flows through a pipe in the heater and is turned into hot water using a gas burner or an electric element. This allows the water heater to provide a constant supply of hot water, whereas a traditional water heater needs to wait for it’s storage tank to fill up with hot water. 

Pros of Tankless Water Heaters

Tankless water heaters are a fairly new technology, and they were developed for good reason. This new type of weather heater’s main perk is that it saves you money on utility bills. Another great benefit of tankless water heaters is that they provide a constant stream of hot water to your home, so that the last person in the shower line will never have to worry about running out of hot water again. One final benefit of tankless water heaters is that they have a longer lifespan than that of a traditional water heater – tankless heaters usually last 20 or more years, in comparison to traditional water heaters that usually only last 10 to 15 years.

Cons of Tankless Water Heaters

The biggest con of purchasing a tankless water heater for your home is that the flow rate is limited. Tankless water heaters generally provide anywhere from 2 to 5 gallons per minute, whereas a traditional water heater can supply a greater flow rate. This can create an issue when running multiple sources of hot water at once, like a dishwater and shower for example, but this problem can be avoided by installing two or more parallel tankless water heaters. Another con of tankless water heaters is that the initial cost is usually greater than that of a conventional water heater, but they last much longer and will save you money in the long run on gas and electric bills.
