What is a tankless water heater?
The primary feature of a tankless water heater is that it is as the name suggests, tankless; therefore, hot water is only provided on demand or as needed. The associated benefit with this particular feature is the reduced energy costs as there is no need to constantly heat a storage tank of water.
How does a tankless water heater work?
When a hot water tap is turned on, cold water travels through the pipe into the tankless water heater unit. If it is an electric tankless water heater, the electrical elements will heat the water. If it’s a gas tankless water heater, the gas burner heats the water; both variations resulting in a constant supply of hot water.
What do I need to consider when choosing a tankless water heater?
- You will firstly need to identify your inlet water temperature (this can be achieved using the image on the right). In colder climates, the tankless water heater will need to work harder to warm the water. In warmer climates, where the incoming water temperature is warmer, your heater will not need to work as hard.
- You will need to determine your gallons per minute requirement. Considerations will include how many people live in your home and what applications you may simultaneously need to heat.
- You will need to identify if you have the necessary electrical requirements to support the unit that you need. Your tankless water heater may need greater voltage requirements and an electrician may be needed to install upgraded breakers and thicker gauge wiring.
- Note: Please ensure you obtain the services of a professional to install your tankless water heater for both safety and warranty purposes.
Additional considerations you may wish to think about include the environmental benefits and the energy efficiency rating.
The new industry standard for measuring energy efficiency in water heaters is now called Uniform Energy Factor (UEF). This new standard recently came into effect on June 12, 2017. The new UEF standards are designed to make it easier for consumers to compare energy efficiency between appliances and the ratings are determined by assigning water heaters into a particular category (4 categories in total) of hot water based on usage and then evaluation of the tankless water heater’s performance based on that usage. A greater UEF indicates that the tankless water heater in that particular category is more efficient.
An interesting document worth reading (click here) has been produced by the US Department of Energy, titled “Transitioning to a Tankless Water Heater”. This document contains everything that is necessary to know prior to selecting and purchasing a tankless water heater.
Tankless Water Heater Pros and Cons
What are the disadvantages to a tankless water heater?
Gas vs Electric Tankless Water Heater…what’s better?
Unfortunately, there is not an answer to this question; both variations have pros and cons and you will need to decide what works best for you. You may not even have an option to decide between the two as availability may be a problem. Let’s look at this further.
Product Cost: A primary factor in making a purchasing decision will be the cost and value for money for a particular product. Electric tankless water heaters will set you back anywhere from as little as $100USD up to $700USD for the device (professional installation will be additional to this). A gas tankless water heater is similar but can be higher in price. The cheapest propane-powered model is approximately $120USD and can range up to $2000USD, therefore, when considering whether gas or electric is a better model, an electric on demand water heater is likely to be a cheaper option over its gas counterpart.
Fuel Costs: In the United States, current gas prices are lower than electricity so this may be a factor worth considering when deciding on the type of tankless water heater model you would like to go with. If you are fortunate enough to have the option of choosing electricity or gas, it’s worth comparing fuel costs in your particular area to identify which method of power will be cheaper.
Environmental Impact: Both gas and electric instant water heaters are significantly more energy efficient than traditional storage hot water systems due to their on demand heating function and they require less energy. The comparison between on demand water heaters both gas and electric in terms of carbon emissions is basically negligible, however gas over coal powered electricity tends to be the preferred greener option.
Installation requirements and costs: Electric tankless water heaters are slightly easier to install. Tankless water heater venting is not a requirement as it is with gas models.

Point of Use Water Heaters
How do Point of Use Water Heaters Work?
Point of use water heaters are designed to improve your hot water distribution system by supplementing your existing hot water system and providing hot water almost instantaneously to your faucet. Additionally, it can also improve your hot water distribution system by preventing heat lost as hot water is being distributed from your central hot water heater to your faucet.
There are two types of point of use water heaters; tankless and tank. Our electric tankless water heater guide features two point of use water heater reviews, the Bosch Tronic 3000t and the Marey Eco110. The Bosch Tronic is not tankless and is designed to hold a capacity of 4 gallons of water in its water tank. It is ideal as a point of use water heater for a shower in the bathroom or a kitchen sink.
