Lochinvar Knight WHB boiler issue in Greater Vancouver

The Lochinvar Knight WHB is a high-efficiency gas boiler that heats homes across Greater Vancouver, and when it develops an issue you notice fast during our long, cool heating season. Here is how to interpret the common symptoms, the checks you can safely make, and when a licensed technician needs to take over.

Common Knight WHB Issues

As a gas condensing boiler dedicated to space heating, the Knight WHB depends on its burner, heat exchanger, circulation, and system pressure working together. Most issues present as no heat, uneven heat, a pressure problem, an unusual noise, or a fault code on the display. Always note the code before resetting, as it points a technician to the source.

Pressure readings and water around the unit are two of the most useful early indicators to keep an eye on.

• A fault or lockout code on the boiler display
• No heat or loops and radiators that stay cold
• System pressure that keeps dropping or rising out of range
• Kettling, banging, or gurgling during a heat call
• Water pooling at the base of the boiler
• Soot, a burning smell, or signs of exhaust spillage

Safe Checks and Professional Repair

Start with the safe basics. Confirm the thermostat is set above room temperature and calling for heat, replace its batteries, read the pressure gauge against the marked range, verify gas is on and other appliances work, and reset a single tripped breaker once. Clearing obstructions around radiators and registers helps the home heat evenly.

The burner, heat exchanger, venting, circulation pump, and any recurring fault code are for a licensed technician. If you smell gas, leave the home immediately and call your gas utility's emergency line before anything else. As a high-efficiency condensing boiler, a Knight WHB replacement may qualify for FortisBC and CleanBC rebates and financing.

• Safe to do: thermostat and batteries, pressure gauge reading, reset one breaker once
• Leave to a pro: burner, heat exchanger, venting, pump, repeating codes
• Gas smell: leave the home and call the gas utility's emergency line first
• A high-efficiency replacement may qualify for FortisBC and CleanBC rebates

Frequently Asked Questions

My Knight WHB shows no heat. What can I check?

Confirm the thermostat is calling for heat with fresh batteries, check the pressure gauge is in range, make sure gas is on, and reset one tripped breaker once. If heat does not return, it needs a technician.

What does a Knight WHB fault code mean?

It tells you where the boiler detected a problem, such as ignition, pressure, or a sensor. Note the code before resetting. A one-off can be cleared, but a returning code needs diagnosis.

Why is the boiler kettling?

Kettling usually relates to deposits or flow at the heat exchanger and should not be ignored. Because it involves internal components, have a licensed technician inspect it.

Is a Knight WHB replacement eligible for rebates?

As a high-efficiency condensing boiler, it can qualify for FortisBC and CleanBC programs when replacing older equipment. HeatLand can confirm eligibility and help with the application.
