Frequently Asked Questions

How Do I Know What Size Water Heater I Need for My Home?

The right water heater size depends on household size, number of bathrooms, and daily hot water usage. Condos and smaller households typically require smaller tanks, while detached homes with multiple occupants may need larger capacities. Usage habits such as back-to-back showers or frequent laundry also affect sizing. A professional assessment helps ensure the water heater meets daily demand without unnecessary energy use.

Yes, all water heaters include manufacturer warranty. Tankstyle water heaters typically come with warranties ranging from 6 to 12 years, depending on the model and brand. Tankless water heaters also comes with warranty ranging 5-10 years Warranty terms vary by manufacturer and installation

On average, water heaters last between 10 and 15 years, depending on usage, water quality, and maintenance. Different locations may experience different lifespans due to water conditions and usage patterns. Regular maintenance and proper sizing can help extend system life.

Yes, hard water can affect a water heater’s lifespan over time. Minerals in hard water can build up inside the tank, reducing heating efficiency and placing extra strain on the system. In many parts of Ontario, hard water is common, which makes regular maintenance important for long-term performance. Using a water softener can help reduce mineral buildup by treating hard water before it enters the water heater. This helps protect the system, maintain efficiency, and support a longer operating life.

Cancellation policies for rental agreements vary by company. Our trained Home Comfort Advisors are happy to assist you during your in-home consultation. Many homeowners choose to replace their rented unit with an owned system to eliminate monthly fees, and LG Home Comfort can guide you through every step of this process.

Water heater prices vary based on type, fuel source, capacity, and efficiency. Storage tanks and tankless water heaters have different cost ranges.LG Home Comfort recommends a consultation to confirm the right system. Flexible monthly payment options are available and are more predictable than renting.

A water heater warms cold incoming water and stores or delivers it to taps when needed. When hot water is used, new water enters the system and is heated again. This simple process ensures that hot water is available for daily household activities without interruption.

Water heaters in Ontario are commonly available in electric, natural gas, and propane options. The right fuel type depends on what utilities are available in your home, operating costs, and hot water usage needs. 

Common water heater fuel types include: 

  • Electric Water Heaters – These systems use electricity to heat water and are widely used in condos and homes without gas access. They are straightforward to install and work well for smaller households with moderate hot water demand. 
  • Natural Gas Water Heaters – Models are popular in many Ontario homes due to faster heating and lower operating costs compared to various systems. 
  • Propane Water Heaters – Typically used in areas without natural gas service. They provide strong heating performance and are suitable for both tank and tankless systems.
