Tankless vs. Tank Water Heaters

Water Heater Comparison for Pickering Homeowners

Let me paint you a picture! It’s a slow Sunday morning in February, the kind where you look outside and instantly feel the cold creeping in. You have hockey later that day, your teenager has friends sleeping over, your wife just started the dishwasher and put a load of laundry into the washer. You step into the shower, turn it on, wait a beat, and then it hits you, cold water. Stone cold! 

This is when people start Googling water heater options. And that’s where I come in! At Home Armour Heating, we have professionals at all levels. We offer consultations, installation, repair and replacements to both tank and tankless water heaters. We are here to service you, in all corners of the Pickering, Ajax, Whitby and Oshawa service areas.

How Traditional Tank Water Heaters Work

A conventional tank water heater does exactly what it sounds like, it holds a reservoir of water holding between 40 and 60 gallons of water for a standard residential unit, while constantly keeping it warm to your set temperature. When you open a hot tap, hot water flows from the top of the tank, cold water enters from the bottom, and the heater gets to work bringing that cold water back up to temperature.

The appeal is simplicity and upfront cost. A standard natural gas water heater installation is going to run you less at the point of purchase and installation than a tankless unit. They are familiar technology, the parts are readily available and most licensed plumbers and HVAC technicians can service them.

The drawback is what is called standby heat loss. Your tank is keeping 50 gallons of water hot around the clock, even when nobody needs hot water. That continuous energy is part of your monthly gas bill, but you’re not getting any value for it. Older units, those approaching 10 to 12 years old, often operate at significantly reduced efficiency. This can be due to several reasons, but the most common are sediment build up in the tank or the heating elements work harder than they should.

How Tankless Water Heaters Work

A tankless water heater operates completely differently than a tank heater. There is no storage tank so when you open a hot water tap, cold water travels through the unit and passes over a high-powered burner or heating element and arrives at your tap hot within a few seconds. When you close the tap, the heater shuts off completely with no standby heat loss! Tankless water heaters have grown in popularity over the past decade since modern units can handle multiple demands better than previous models. Think more hot water flowing through the house even if you flush a toilet or start the washing machine.  

Natural Resources Canada estimates that on-demand water heaters can be 24 to 34 percent more energy efficient than conventional storage units for households with moderate to high hot water usage.

Water Heater Installations Upfront Cost vs. Long-Term Savings

Here is where it gets interesting, breaking the cost savings down and understanding what is the better value, upfront cost or long term savings.

A standard tank water heater for a family home typically runs $900 to $1,500 depending on tank size and the complexity of the installation. A tankless unit from a quality brand, installed by a professional usually ranges between $2,500 and $4,500. Tank water heaters typically last 8 to 12 years. Tankless units, with proper maintenance including annual descaling last roughly 20 years or more. Over a 20-year window, you are often looking at buying and installing two or more tank heaters versus one tankless unit. When you factor in energy savings on top of that, the long-term math often favours the tankless option, particularly for families with high hot water demand.

Installation Considerations for Durham Region Homes

Switching from a tank to a tankless water heater is not always a straight swap. Tankless units typically require a larger gas line to handle the higher BTU demand during operation. In many older homes built in the 70s and 80s, the existing gas line size may need to be upgraded which adds to the installation cost. Additionally, tankless units need proper venting and the venting configuration may differ from what is in place for your existing tank unit. We offer free consultations to find the solution that works for you.

Consider Renting vs. Buying A Water Heater

A significant number of homes in Durham Region have rented water heaters, typically through Enercare or a similar provider. If that is you, there are a few things worth understanding. The monthly rental fee you pay for the unit often exceeds what you would have paid to purchase the unit outright. Depending on your provider, there could be buyout options available. Oftentimes, buying out a rental water heater and replacing it with a purchased tankless unit makes financial sense over 10 to 15 years. We help homeowners navigate whether owning or renting is the better option for them.

Questions About Water Heater Options in Pickering

Will a tankless water heater actually keep up with my family's demand?

For most families, yes, provided the right unit is selected. A properly sized tankless water heater, matched to your household’s peak demand in gallons per minute will handle simultaneous showers, laundry, and dishwasher use without issues. The key word there is properly sized. We size every unit we install based on your home’s actual usage patterns and the number of fixtures drawing hot water simultaneously.

How much maintenance does a tankless water heater require in Ontario?

Annual maintenance is recommended due to the water hardness levels throughout Durham Region. Hard water causes mineral scaling inside the heat exchanger over time which reduces efficiency and can shorten the unit’s lifespan. Annual descaling, which involves running a vinegar or citric acid solution through the system keeps the unit running at peak efficiency.

Are there rebates available for tankless water heater installation in Ontario?

Potentially, yes! Enbridge Gas has offered rebates for newly installed and efficient water heaters in the past and Canada Greener Homes incentives have included water heating upgrades. Program availability and amounts change, so we always recommend checking current status at the time you are ready to move forward.
