Tankless Hot Water Tanks - The Right Choice for My Home?

If your home’s water heater has tanked, replacing it can be a thankless job as you investigate your options. One of the best choices available is the tankless water heater, which produces hot water on demand.

If you’re living in an older home, the chances are that your water heater is one of those huge 40-litre tanks that are found in basements everywhere. It can take up a lot of room that could be used more productively and, frustratingly, when you use too much hot water in a short span of time, your supply can run out (e.g., a hot bath and a simultaneous dishwasher cycle).

In terms of purchase price alone, it’s cheaper to replace the tank than to consider alternatives, but when it comes to efficiency and cost savings over time, you may want to consider the tankless option.

Talking Tankless

For anyone unfamiliar with tankless water heaters, these units offer hot water at the turn of a tap, but they don’t store water on site. They are small and compact – the size of a suitcase or smaller – and are generally mounted on the wall. Rather than storing water, they extract it from the ground on demand and use a heat exchanger – electric coils or a gas burner — to warm it before it reaches the consumer.

Depending on your needs, you can purchase a tankless heater for the entire home or you can install individual units for particular rooms/areas of the house. 

Tankless heaters have been popular in Europe and Asia for many years, but they have only recently become fixtures on the Canadian market.

Pros of Going Tankless

Longevity

Tankless water heaters last for 20 years or more, compared to the 10-year life for most water tanks.

Operating cost

With a tankless heater, you aren’t paying to keep water at a constant temperature day in, day out, whether you are using it or not, as is the case with a hot-water tank. Instead, you are drawing water from the ground as needed. Your utility bill should reflect this savings.

Energy savings

Keeping the water in a tank heated 24/7 results in what is termed standby heat loss, the energy wasted by keeping water heated at a constant temperature. Tankless heaters save energy by heating water only when required – between 8 and 34 per cent.

Safety

Water tanks can spring a leak and flood the basement; harbour dangerous bacteria like Legionella or crash to the floor during an earthquake. None of these are concerns with tankless heaters; nor do homeowners need to worry about backdrafts of carbon monoxide leaking into the house, because the air-supply and exhaust vents for tankless heaters are sealed.

Winterizing

If you’ve had to drain a water tank as you close up your summer home, you know how long it can take. A tankless heater makes it easy – using a compressor, you can drain the unit in a few seconds, unplug it and away you go.

WiFi compatibility

Thanks to technology, tankless units can be controlled remotely. You digitally can adjust the water temperature and monitor fuel and hot water usage using your cellphone.

On the Other Hand

Purchase price

Tankless water heaters are more expensive than water tanks. Over time, a user will recoup that cost, but if you’re looking for savings upfront, a tankless heater isn’t the best choice.

Slow flow sensitivity

 If there is mineral buildup in your pipes or the faucet and shower head aerators become clogged, water may flow too slowly to the point of use and the tankless unit will shut down. This won’t happen with a water tank.

Location, location, location

Ground water temperature will be affected by how far north you live, which can affect the speed and flow of the water moving through your system and the amount of energy required to heat the water.

Before you decide on a tankless heater, consider these issues, run the numbers and also think about whether you’ll want one tankless unit or a few. Electricity works well for room-sized units, while gas is best for the entire home – and may require an upgrade to your gas lines.

If you do purchase a tankless water heater, you’ll want the help of an HVAC professional for both installation and maintenance.
