Pros and Cons of 5 Different Water Heaters

Pros and cons of 5 different water heaters

Share This Post

Did you know your water heater is the second most demanding appliance in your home? Next to your HVAC system, this hardworking appliance runs 24/7 to deliver hot water to your appliances and faucets

Knowing this, you might consider whether there are better options to meet the needs of your household while also helping to conserve energy. Here, we look at five pros and cons of different water heaters from the professional plumbers Leaside homeowners trust, to help you find the most efficient water heater available. 

1. Conventional or Storage Tank Water Heaters  

Unless you live in a newly built home, you’ll likely have some form of a storage-tank water heater. These water heaters store between 115 and 190 litres of hot water, ready for use when you need it. Our plumbers in Leaside suggest you consider the following pros and cons for this traditional option:


  • The most affordable option
  • The easiest model to install
  • They are readily available
  • They are inexpensive to replace
  • New models are Energy Star certified


  • Even Energy Star models must be running 24/7 to keep the stored water hot
  • Because they hold up to 190 litres of water, they take up a lot of space 
  • In larger households you can run out of water quickly, which means unexpected cold showers 
  • In most households, you can’t run the laundry or dishwasher AND take a hot shower
  • Only lasts between 12 and 15 years
  • The most efficient storage tank only has an energy factor of around .67

2. Tankless Water Heaters

The tankless water heater is making a big impact on the water heating industry. As the name suggests, these water heaters do not rely on a storage tank to provide hot water. Instead, they use a small tank mounted on the wall where water is fed through the system to heat the water on demand. 

As a result, you save energy as the system isn’t running 24/7. The pros and cons of the tankless water heater, according to our expert plumber in Leaside, include:


  • Reduces energy consumption by as much as 25%
  • More affordable to operate due to the 25% energy savings
  • Have an energy factor as high as .95 which helps pay for the unit over time
  • Delivers a continuous supply of hot water at a rate of roughly 7.5 to 20 litres per minute
  • Not much larger than the average briefcase
  • Mounts on the wall out of the way, taking up very little space 
  • Lasts upwards of 20 years
  • Can be installed anywhere in the house
  • Can be installed with more than one unit to meet different needs of the house, such as the bathrooms, laundry room, kitchen
  • When installed in a newly built home, installation costs are comparable to a conventional tank 


  • Twice the price of a conventional water heater
  • Parts and installation for the tankless water heater are very expensive, adding to the costs
  • Conversion to a tankless system can cost up to $3000 when retrofitting an older home
  • You need a gas-run system to see energy efficiency
  • Can see reduced flow when more than one person is using hot water
  • Large households usually need more than one unit

3. Heat Pump Water Heaters

These are less commonly installed water heaters but can be a good choice for homes with heat pumps. However, they can be used as a hybrid system if you have a traditional heating system. 

They may soon start to gain more popularity as they don’t need to generate their own source of heat but instead use heat in the ground and surrounding air, making them very energy efficient. The pros and cons, according to our top plumber in Leaside, include:


  • Energy efficient
  • Green energy operated
  • Lower maintenance than other water heaters


  • Are more practical in warmer climates
  • Costly to both purchase and install
  • Take up a lot of space

4. Condensing Water Heaters

You likely haven’t heard of this type of water tank before! They are designed for homes that rely 100% on natural gas and operate much like a conventional tank using stored water. However, they are far more energy efficient, heating smaller amounts of water than a conventional system. Pros and cons include:


  • Energy efficient choice for natural gas households
  • Provides hot water on demand like a tankless system
  • Lasts longer than the average tank


  • Available, but not practical for electric households
  • Are prone to corrosion, which means there can be a higher risk of leaks as the tank ages
  • Costs more than the average tank system

5. Solar Powered Water Tanks

This is the ultimate eco-friendly water tank option, but for the most part is not practical for Ontario homeowners. First, it requires solar panels mounted on the roof. Second, it can mean no hot water when the weather has been cloudy. Third, because of unpredictable weather, you’ll need a backup. The pros and cons include:


  • Long life
  • Very energy efficient and “green”
  • Backup heaters provide hot water when needed
  • Low maintenance system


  • A backup system might end up providing most of the water in Ontario’s cold, dreary seasons
  • High costs to purchase and install compared to conventional systems
  • Not practical for homes on shady properties
