Are you considering upgrading to a tankless water heater? These modern, energy-efficient systems provide on-demand hot water, making them a popular choice for homeowners looking to save space and reduce energy bills. But are they the right fit for your home?

At Plombier Candiac, we specialize in water heater installations and repairs, helping homeowners choose the best system for their needs. In this guide, we’ll break down the pros and cons of tankless water heaters to help you decide if it’s time to make the switch.

What Is a Tankless Water Heater?

Unlike traditional water heaters that store a large tank of hot water, a tankless system (also called an on-demand water heater) heats water only when you need it. When you turn on a hot water tap, the unit instantly heats water as it flows through—providing a continuous supply of hot water without a bulky storage tank.

? Tankless water heaters can be powered by gas or electricity and are designed to be more energy-efficient than traditional tank models.

Pros of Tankless Water Heaters

✅ 1. Unlimited Hot Water Supply

Since tankless water heaters heat water on demand, you won’t run out of hot water—even during long showers or back-to-back usage.

✔️ Ideal for large families or homes with high hot water demand.
✔️ No waiting for a storage tank to refill and reheat.

✅ 2. Energy Efficiency = Lower Utility Bills

Tankless water heaters are 25-35% more energy-efficient than traditional water heaters because they only heat water when needed.

✔️ Saves on energy costs—no standby heat loss like traditional tanks.
✔️ Gas-powered models save more energy than electric models.

? Tip: Homes that use less than 40 gallons of hot water per day can save up to 30% on energy bills with a tankless system.

✅ 3. Saves Space & Offers Flexible Installation

Tankless water heaters are compact and wall-mounted, making them perfect for small homes, condos, and apartments.

✔️ Takes up less space than a traditional water heater.
✔️ Can be installed on a wall, inside cabinets, or even outdoors.
✔️ Frees up valuable storage space in your basement or utility room.

✅ 4. Longer Lifespan Than Traditional Water Heaters

A tankless water heater lasts 20+ years, compared to 10-15 years for a traditional tank system.

✔️ Fewer replacements = long-term savings.
✔️ Easily replaceable parts extend the unit’s lifespan.

✅ 5. Reduced Risk of Water Damage

Traditional water heaters can leak or burst, causing flooding and water damage. Since tankless systems don’t store water, there’s less risk of leaks and water damage.

? Warning: While tankless systems don’t have a large storage tank, they can still develop minor leaks over time, so regular maintenance is essential.

Cons of Tankless Water Heaters

❌ 1. Higher Upfront Cost

The initial cost of a tankless water heater (including installation) is higher than a traditional unit.

✔️ Average cost: $1,000 - $3,500 (vs. $500 - $1,500 for traditional heaters).
✔️ Installation may require upgrades, such as new gas lines or electrical work.

? Tip: The energy savings over time help offset the upfront cost, but it may take several years to break even.

❌ 2. Limited Hot Water Flow Rate

While tankless systems provide endless hot water, they have a limited flow rate, meaning they can struggle to supply multiple fixtures at once.

✔️ Best for smaller households with moderate water use.
✔️ Larger homes may need multiple units to meet demand.

? Example: If you’re running the shower, dishwasher, and washing machine at the same time, a single unit may struggle to keep up.

❌ 3. Requires Professional Installation

Installing a tankless water heater is more complex than a traditional unit.

✔️ May require new gas lines, ventilation, or upgraded electrical circuits.
✔️ Installation costs can be higher, depending on your home’s setup.

❌ 4. Inconsistent Water Temperature in Some Cases

Tankless water heaters work best with steady water flow, but sudden changes in usage can cause temperature fluctuations.

✔️ Some models struggle with low water flow rates.
✔️ A recirculation pump can help maintain consistent hot water.

? Tip: Choose a high-quality unit with advanced temperature control to avoid this issue.

Should You Switch to a Tankless Water Heater?

Tankless Water Heaters Are a Great Choice If:

✔️ You want energy efficiency and lower utility bills.
✔️ You have limited space and need a compact water heater.
✔️ Your household doesn’t use multiple hot water sources at the same time.
✔️ You plan to stay in your home long enough to benefit from long-term savings.

You May Want to Stick with a Traditional Water Heater If:

❌ You have a tight budget and can’t afford the higher upfront cost.
❌ Your home requires extensive upgrades for installation.
❌ You need high water flow for multiple appliances at once.

A tankless water heater offers energy savings, unlimited hot water, and a longer lifespan, making it a great investment for many homeowners. However, higher upfront costs, installation complexity, and flow rate limitations should be considered before making the switch.
