All of the appliances in your home have a lifespan, including your water heater. Unfortunately, things corrode, break down and fall apart. Fortunately, there are steps you can take to lengthen the lifespan of your hot water tank.


Regular maintenance can help prevent unforeseen repairs or replacement of your water heater. If your water heater stops providing you with hot water, our technicians at Aire One Heating & Cooling KW are available 24/7.


As water heaters age, they can develop problems if they are not properly maintained. Common water heater problems include:

Leaks. Water pooling around your water heater can be sign of a broken or loose seal.


Unusual sounds. If your water heater is making an unusual popping noise or growling sound that could be a sign that you have sediment built up in the tank.


No hot water. A lack of hot water could mean that the breaker has tripped (for an electric water tank) or there is no gas.​​


The pilot light goes out. If your pilot light doesn’t stay lit, you may have a faulty thermocouple.

Aire One KW offers water heater repair services in the Waterloo, Guelph, Cambridge and Woodstock areas. With scheduled, regular visits, a technician can catch minor problems before they become expensive repairs. Give us a call today for a water heater inspection.

  • How often should I service my boiler?
    A minimum of once a year is recommended. Heating systems come on an average of 3-8 times per hour during the heating season, these numbers can change dramatically in different style of homes and with different thermostats, but this is a rule of thumb in our industry. There is a lot of wear and tear on the appliance and setting can go out of calibration. Also, it is a requirement by most manufacturers and home insurance companies.
  • Can I add new zones to my existing boiler heating system?
    It depends if the btu output of the radiators has reached the maximum btu output the boiler can support. Having a professional to come out and calculate is your best bet.
  • How will I know if the boiler I select will work properly for my home?
    Each room will have a radiator and every radiator has a specific btu output . We calculate the total of the radiator btu outputs, match that with a heat loss/heat gain calculation for the home and that is how we size a boiler system for your home.
  • How does a boiler work to heat my home?
    A boiler is a device that heats water and then distributes the hot water throughout your home to warm the indoor air. There are two main types of boilers: hot water boilers and steam boilers. Hot water boilers heat water to a temperature of about 82 C. The hot water is then circulated through a system of pipes and radiators throughout the home. The radiators give off heat to the surrounding air, which warms the home. Steam boilers heat water to a temperature of about 100 C, which is the boiling point of water. The steam is then distributed through a system of pipes and radiators throughout the home. The steam condenses back to water on the radiators, which gives off heat to the surrounding air, warming the home. In both hot water and steam boilers, the water in the pipes cools and returns to the boiler after heating the interior spaces. The water is then reheated and recirculated throughout the home. Some boiler models also double as a water heater, eliminating the need for a separate water heater unit. The efficiency of a boiler is measured by its Annual Fuel Utilization Efficiency (AFUE) rating. The AFUE rating is a percentage of the fuel that’s used to heat the water that heats the home. The higher the AFUE rating, the more efficient the boiler. Boilers with medium levels of efficiency have ratings of 90 to 93 per cent.
  • What is the average lifespan of a residential boiler?
    The typical residential boiler can last between 15 and 20 years. You can find the year your boiler was manufactured by checking the unit’s rating plate. You can also call the manufacturer and give them the unit’s serial number to find out how old your boiler is. If your boiler unit is more than 15 years old, you should consider replacing it with a new boiler, high-efficiency gas furnace or heat pump.
  • Are there any government rebates available for my boiler upgrade?
    Unfortunately, Ontario homeowners in the Tri-Cities area wanting to invest in a new boiler system for their homes aren’t eligible for rebates under the Home Efficiency Rebate Plus (HER+) program. Heat pumps are the only home heating system covered under HER+, whereby homeowners can get more than $10,000 in rebates on a heat pump installation. This program combines the Enbridge Gas rebate program and the Canada Greener Homes Grant.

Below are some things to consider whether or not you should repair or replace your existing water heater:

  • Safety. If your hot water tank is old and outdated, it may not meet current safety guidelines. If this is the case, replacement may be the best option.

  • Cost of the repair. It can be challenging to find replacement parts for older water heaters. New parts can be expensive and you will also have to pay for labour. 

  • Energy efficiency savings. Even if a technician can fix your water heater, it may be less expensive in the long run to invest in a new water heater or a high-efficiency tankless water heater now.

  • Frequency of repairs. If you see your water heater repair technician too often, it may be time to consider replacing the tank.

  • Future lifespan. Think of the lifespan of your current water tank and the costs associated with keeping it alive. Remember, any repairs needed for the new model will be covered by a warranty.

A consultation with Aire One Heating & Cooling Kitchener-Waterloo can help you decide the best way forward.
