Signs It’s Time to Replace Your Boiler
While we offer expert boiler repairs and maintenance, there comes a point where a repair is just a temporary fix for an aging system. It may be more cost-effective to invest in a new boiler installation if you notice any of the following:
-
System Age Over 15–20 Years: Most traditional boilers are designed to last 15 to 20 years. Beyond this, efficiency drops significantly, and the risk of a major “no heat” emergency during a cold snap increases.
-
Skyrocketing Energy Bills: If your gas bills are rising despite consistent usage, your boiler is likely working twice as hard to produce the same amount of heat. Upgrading to a high-efficiency Navien system or a modern combi-boiler can often pay for itself in energy savings.
-
Frequent or Costly Repairs: If you’ve had a technician out more than twice in the last year, you are likely “throwing good money after bad.” A replacement provides peace of mind and a fresh warranty.
-
Strange Noises (Kettling, Banging, or Whistling): Unusual sounds often indicate a build-up of lime or sludge on the heat exchanger. This “kettling” restricts water flow and causes the unit to overheat and eventually fail.
-
Uneven Heating and Cold Spots: If some rooms are freezing while others are too hot, your boiler’s pump or internal components may no longer be able to manage the circulation requirements of your home.
-
Visible Corrosion, Rust, or Leaks: Any signs of water pooling or rust on the jacket or piping are critical warnings. Corrosion can lead to catastrophic tank failure and water damage to your property.
-
Slow Heat-Up Time: If your radiators take significantly longer to get warm than they used to, or if your hot water delivery is unreliable, the unit is struggling to maintain its BTU output.
-
Yellow Pilot Light (Gas Boilers): A healthy pilot light should be blue. A yellow flame can indicate carbon monoxide issues or improper combustion, which is a serious safety hazard that often necessitates an immediate boiler replacement.
-
Inconsistent Hot Water: If you are losing hot water mid-shower or the temperature fluctuates wildly, your boiler’s internal heat exchanger is likely scaled up or failing.
Types of Boilers We Install
We install and replace a wide range of residential boiler systems and help you choose the best option for your home.
Conventional Boilers
Best suited for larger homes with higher hot water demand. These systems work with a storage tank and provide steady, reliable heating.
Combi Boilers
A compact, energy-efficient option that provides both heating and on-demand hot water without a separate tank. Ideal for smaller homes, condos, and townhouses.
High-Efficiency Condensing Boilers
Modern systems designed to maximize fuel efficiency, reduce operating costs, and improve overall heating performance.
Our team will assess your home’s size, layout, water usage, and heating requirements before recommending the right system.

Boiler Replacement FAQs
On average, a new residential boiler installation in the Lower Mainland ranges from $8,000 to $15,000+, depending on the unit’s BTU capacity and the complexity of your hydronic system. High-efficiency condensing boilers like Navien typically sit at the higher end but offer significant long-term gas savings and qualify for local rebates.
Most residential boiler replacements are completed within one full workday. This includes removing the old unit, installing the new boiler, updating the gas lines and venting to code, and performing a full system flush to ensure your radiators or in-floor heating loops are clear of debris.
Yes. Removal and proper disposal of the existing boiler are included.
Yes. Modern high-efficiency boilers typically reduce heating costs while improving comfort and performance.
You should consider a boiler replacement if your current unit is over 15 years old, requires repairs exceeding 50% of its value, or if your energy bills have increased by more than 20%. While a repair can fix immediate leaks, a new high-efficiency installation provides a fresh 10-year warranty and superior reliability during BC’s cold winter months.
Condensing gas boilers and Combi-boilers (like those from Navien or Viessmann) are currently the most efficient options, often boasting AFUE ratings of 95% or higher. These systems use a second heat exchanger to capture heat from exhaust gases that traditional boilers waste, making them ideal for meeting CleanBC energy standards.
Yes. A combi-boiler (combination boiler) is designed to provide both whole-home hydronic heating and on-demand domestic hot water from a single compact unit. This replacement is an excellent way to save space in your mechanical room and eliminate the need for a separate, bulky hot water tank.
