London Tankless Water Heaters

Upgrading to a tankless water heater is a forward-thinking decision for London homeowners looking to increase energy efficiency, lower operating costs, and modernize their home’s plumbing system. Unlike traditional water heaters that continuously heat stored water, tankless models warm water only when it’s needed—resulting in significant energy conservation and better performance.

As more families in London and surrounding areas such as Arva, St. Thomas, Strathroy, and Belmont seek reliable and eco-conscious upgrades, on-demand water heating is becoming a popular choice. These systems are ideal for both new constructions and retrofits, offering exceptional efficiency, cleaner water, and a smaller physical footprint.

Designed with versatility in mind, tankless systems fit neatly into tight corners or mechanical rooms and can be installed closer to point-of-use areas—reducing wait times and heat loss.

Why London Homeowners Are Switching to Tankless Water Systems

At The Super Plumber London, we install high-performance tankless units that are built to last and designed to deliver constant hot water flow. Here’s why more homeowners across London are making the switch:

• Optimized Energy Usage – Unlike tank heaters that burn energy maintaining water temperature, tankless systems only heat when taps are turned on, helping cut monthly bills and shrink your carbon footprint.
• Lower Maintenance Needs – With no storage tank to rust or collect mineral deposits, these units generally require fewer repairs and routine flushes—making upkeep easier.
• On-Demand, Clean Water – Hot water is heated instantly as it moves through the system, ensuring every shower or wash uses fresh water—free from stagnant tank sediment or mold buildup.
• Slim, Wall-Mounted Design – Compact units take up minimal room, freeing space in utility closets, small apartments, or finished basements where every square foot matters.

Typical Tankless Water Heater Problems in London-Area Homes

Even cutting-edge systems may develop issues over time. Early identification and fast intervention are crucial for keeping your household operations uninterrupted.

• Faulty Installation or Inaccurate Configuration
  For tankless units to operate efficiently, everything—from venting routes and gas line sizing to water supply connections—must be perfectly aligned. A poorly installed unit can cause erratic temperatures, increased gas or electricity use, and ongoing system strain. At The Super Plumber London, our team ensures every unit is installed to the manufacturer’s specifications and in accordance with Ontario building codes.

For heritage or retrofitted homes in the London region, we offer customized solutions to avoid future issues and streamline performance upgrades.

• Limescale Build-Up and Corrosive Damage
  Hard water is a well-known issue in London and surrounding towns, and it contributes to scale buildup inside tankless heaters. This mineral accumulation restricts water flow, increases internal pressure, and can lead to component failure. Annual descaling helps maintain performance, while installing a water softener can drastically reduce long-term wear.

Tip: Staying on top of maintenance not only extends equipment life but also keeps your energy usage efficient year-round.

• System Too Small for Household Needs
  Choosing an undersized unit for a busy household is one of the most common mistakes. If your family uses multiple showers, laundry machines, or dishwashers at once, a small unit will struggle to keep up. We conduct in-depth evaluations to match your heater to your actual and future usage needs—like basement renovations or growing families.

We also offer multi-unit setups for large homes, ensuring steady hot water flow even during high-demand periods.
