Save Energy, Space, and Money with a Tankless Water Heater 

As the temperature outside starts to decrease, the temperature of the water used inside for those hot showers and steaming cups of coffee starts to increase. But what happens when you have not rinsed shampoo out of your hair or start running water for your next mug and all of the sudden that water goes quickly from hot, to lukewarm, to cold?

Whether you are struggling with your water heater keeping your water warm or tired of dealing with the sky-high prices that are on your bill, it is time to find a solution that works best for your home. A terrific way to save energy, money, and potentially even space is to invest in a tankless water heater. 

What exactly is a tankless water heater?

“Tankless,” “instantaneous,” and “demand-type” are all synonymous when referring to this type of water heater. Just like a traditional water heater, the product is hot water; what is unique about the tankless water heater is the process to that product.

A traditional water heater has a large tank that stores a reserve of water that is constantly heated. When you turn on a hot water valve, the water is released, the storage tank is refilled, and that new water will sit, heated, until it in turn is used.

A tankless water heater, though, does not use a tank – hence the name! Instead, the entire water supply is stored in one unit. When you turn on the hot water valve, a heating mechanism is immediately triggered and the water is warmed for as long as the hot water tap is on. Then, the water is sent through a pipe and out of a faucet. 

There are numerous factors to consider when choosing a tankless water heater. First, determine if you want the machine to be powered by gas or electricity. Following that is the flow, as different types of tankless water heaters offer varying flow rates. Also, be sure to secure a warranty that protects the heat exchanger, as this is a tankless water heater’s core component.

Pros & Cons of a tankless water heater

Commercial Service prefers the tankless water heater for a myriad of reasons, but they might not be for everyone. Below are some areas that you should consider before your water heater purchase.

Cost and Lifespan

Tankless water heaters will be more expensive upfront. A traditional water heater will cost around $500, while a tankless water heater starts at around $1,000. However, do not let this initial cost deter you. A tankless heater will last roughly 10 years longer than a traditional water heater, which could possibly save you thousands in expenses compared to the traditional water heater in the long run.

Energy Efficiency

When it comes to energy efficiency, it is agreed that the tankless water heater is one of the best solutions on the market. In fact, Consumer Reports indicated that the tankless water heaters are 22 percent more efficient than standard models.1 By virtue of not keeping water in a storage tank that requires nonstop warming, the tankless water heater wastes no energy on water not being presently used. One of the leading manufacturers in energy-efficient tankless water heaters, Energy Star, states that by “heating water only when you need it… tankless water heaters save a family of four… $1,800” over the lifespan of the machine2.

Access and Consistency of Temperature

The obvious benefit of a tankless water heater is that hot water is available almost instantly. In contrast, the traditional water heater’s temperature could be significantly cooler, especially if there is a larger quantity of water in the tank. Tankless water heaters are not without their challenges, though. Inconsistent temperatures have been reported, most likely due to multiple hot water needs at one time. If someone is taking a shower, another person is running the dishwasher, and someone has a load going in the washing machine, a tankless water heater might struggle to keep the supply of hot water evenly.


Usually a tankless water heater will cost a bit more to install, however the absence of the tank will allow you to save some additional square footage.
