How Does A Tankless Water Heater Work?

Tankless water heaters, also known as on-demand hot water heaters, don’t use a storage tank to heat and store water. Instead, these water heaters instantly heat water as it is needed, providing a continuous supply of hot water. This cuts down on energy used to heat water, resulting in lower utility costs.

When you turn on a hot water tap, cold water passes through a heating element powered by gas or electricity. This heats the water, which is then delivered through the pipes to the tap and ready to use.

Tankless heaters with buffer tanks and recirculation systems reduce the amount of time waiting for hot water, saving energy and money while eliminating the “cold water sandwich” effect.

What Size Tankless Water Heater Do I need?

A water heater must be the right size to provide an adequate supply of hot water for the household’s needs, while also being cost effective. The size of the water heater must take into account the household’s water usage and hot water requirements.

To calculate the proper size, you need to consider two factors; The Flow Rate and the Temperature Rise.

The Flow Rate indicates the amount of water you need at a given time and measured in gallons per minute (GPM). You can find the GPM by adding the flow rates of each fixture together.

The Temperature Rise is the difference between the groundwater temperature (water supply) and the desired temperature at the faucets. In Ontario, the groundwater in winter is around 37 degrees. If your desired temperature is 140 degrees, then the temperature rise will be 103 degrees Fahrenheit.

Once we have the total flow rate and the required temperature rise, we can calculate the right-size tankless water heater.

What is Condensing Tankless Water Heater?

Vapor is a byproduct of burning fuel. Ultra high energy efficient condensing gas water heaters utilize two heat exchangers. Condensing gas water heaters use a secondary heat exchanger to absorb and recycle heat from hot water vapor, preheating the water, rather than venting the vapor outside like non-condensing systems.That’s why they are more efficient than non-condensing types of water heaters.

Factors to Consider When Buying a Tankless Water Heater

It’s important to consider several factors before investing in a tankless water heater. These factors include:

Size (Capacity)

Tankless water heaters capacity is measured based on their flow rate (Gallon Per Minute or GPM). It’s always recommended to contact a licensed and professional HVAC technician to calculate the right size of water heater for your house but to have an estimate, you can add up the flow rate of the faucets, showerheads, washing machine and dishwashers.

Fuel type and availability

When selecting a tankless water heater, it’s important to consider what energy source is available in your area and what is the cost of it. The type of energy you use affects the annual operation costs, tankless water heater’s size and efficiency.

Installation of electric tankless water heaters normally cost less than gas fueled water heaters as they don’t need gas and flue piping. While they are more efficient compared to their gas fueled counterparts, efficiency always doesn’t mean saving. Electricity costs tend to be more expensive than natural gas and propane. Electric tankless water heaters also have limited flow rate while gas models can have greater flow rate and meet higher hot water demands.

Energy Efficiency

The energy efficiency, also known as Energy Factor (EF), indicates a water heater’s overall energy efficiency based on the amount of hot water produced per unit of energy consumed. The higher the energy factor, the more efficient the water heater. As mentioned before, condensing tankless water heaters come with higher efficiency and energy factor.

Proper Installation

Proper installation is also one of the key factors to consider when investing in a new tankless water heater. It’s important to have a qualified HVAC contractor install your tankless water heater.

There are many important factors to consider when installing a tankless water heater such as proper and safe gas piping which must be done by a licensed gas technician and according to the local codes, as well as flue pipes for gas fueled water heaters. Electrical tankless water heater installation also may require electrical wiring by a qualified electrician.

The Cost of Installing a Tankless Water Heater

The installation price of a tankless water heater can vary greatly depending on the type of unit, technology used (condensing or non-condensing), fuel source (gas or electric), and the location of the installation.

On average, the cost of installing a gas tankless water heater is between $3,000 and $7,000, while the cost of installing an electric tankless water heater is between $2,000 and $6,000.

Furthermore, installation costs may also be affected by additional features, such as a recirculating pump, which may increase the total cost.
