Water Heater Comparison – Tank vs. Tankless vs. Hybrid

Energy-efficient traditional tank hot water heater.

1.     Traditional Tank Water Heaters – Electric and Gas

Electric and gas water heaters are the most common types of water heaters used and heat water using electricity or gas.


  • typically lower cost to purchase
  • easily installed


  • not usually as energy efficient as tankless models
  • heat can be lost through the sides of the tank causing the heating mechanism to keep coming on to reheat the water

Traditional tank hot water heaters are the most common type of hot water heater in most Hamilton-area homes and elsewhere across Ontario and Canada.

We carry several different brands and models, of all sizes from 20 to 60+ gallons to suit homes, condos, and cottages, and families of all sizes.

2.     Tankless Water Heaters

Energy-efficient tankless hot water heater.

Tankless water heaters have become popular and a preferred source for hot water due to the long term savings realized. These types of water heaters are also known as demand water heaters.


  • cold water entering the house is instantaneously heated to a desired temperature on demand and as needed
  • unlimited hot water
  • more energy  efficient, since water is only heated when needed
  • can last 5 to 10 years longer than a traditional tank water heater. It also provides an unlimited supply of hot water (without having to wait for the water to heat back up)
  • takes up much less space than a tank model
  • conserves water, since they can be placed closer to kitchen or main bathroom


  • The downside to a tankless water heater is it is more expensive to purchase and install and may require some necessary upgrades to a natural gas line or venting system. The excellent benefits and long-term savings, however, usually outweigh the initial cost.

3. Hybrid Water Heaters:

Hybrid models vary but essentially combine the technology of a tank and tankless water heater to provide an unlimited supply of hot water to the home with the added benefit of the highest level of energy efficiency and cost savings.


  • hybrid water heaters are highly energy efficient
  • saves you hundreds and even thousands of dollars in energy costs each year


  • higher initial cost

How Do They Work?

Water Heater Basics
Water coming into a home is cold. As it flows through the pipes it goes into the water heater and flows through a dip tube to the bottom of the tank where a heating mechanism (such as a burner or heating element) starts to heat up the water. The heating mechanism remains on until the water reaches the required temperature which is set via the water heater thermostat.

Water Heater Temperature Reminder for Families with Young Children

Setting the temperature on a lower setting is highly recommended when there are children in the home and it also helps to save energy.
