Lochinvar Cadet boiler guide for Greater Vancouver
The Lochinvar Cadet is a compact, wall-mounted condensing boiler aimed at residential hydronic heating. For Greater Vancouver homeowners with tight mechanical spaces, its small footprint and wall-hung design make it an appealing high-efficiency upgrade.
Lochinvar is a well-established manufacturer with a solid parts and support presence, which helps ensure dependable service over the boiler’s life. The Cadet fits within Lochinvar’s residential lineup as a space-friendly option for homes that don’t need a large, high-capacity unit.
This guide explains what the Cadet is, the homes it suits, how it’s installed and vented in our region, and what maintenance involves. We keep the details general and accurate and direct you to a written HeatLand quote for the specifics of your home.
What the Cadet boiler is
The Lochinvar Cadet is a compact, wall-mounted condensing gas boiler for hydronic space heating, radiators, baseboard, or in-floor systems. As a condensing boiler, it recovers heat from flue gases that a conventional unit would waste, and it vents through sealed plastic venting rather than a chimney.
The Cadet uses a modulating burner, so it can adjust output to match heating demand rather than simply cycling on and off. That supports steadier comfort and efficient operation across mild shoulder-season days and colder stretches alike. Its compact, wall-hung form is a defining trait, designed to fit installations where space is at a premium.
The Cadet is oriented toward residential loads rather than large or light-commercial applications. For domestic hot water, it’s typically paired with an indirect tank rather than functioning as a combi. HeatLand can confirm whether the Cadet’s capacity and footprint suit your home.
Who it suits in Greater Vancouver
The Cadet suits homeowners with a residential hydronic system who want a high-efficiency boiler that fits a compact mechanical space. Its small footprint and wall-mounting are genuinely useful in condos, townhomes, and smaller houses where floor and wall space are limited.
Because it’s a heat-only boiler, it’s usually paired with an indirect tank for domestic hot water, keeping the heating and hot-water components separate and independently serviceable. Homes with modest to moderate heating loads are the natural target; larger homes with many zones may need a higher-capacity boiler.
Lochinvar’s established support network is a practical benefit for long-term ownership. In our mild, damp climate, condensing boilers spend much of the season in their efficient condensing range, which rewards the upgrade. HeatLand reviews your distribution type, heating load, hot-water needs, gas supply, and venting route before recommending the Cadet over other options.
Installation and venting
Even a compact condensing boiler needs a proper venting and condensate plan. The Cadet vents through sealed plastic venting with defined termination clearances and produces acidic condensate that must drain to an approved point, often through a neutralizer. Combustion-air supply and clearances are planned alongside the venting route.
Gas supply is part of the assessment: an upgrade may call for a review of gas line sizing to ensure adequate flow, particularly when other gas appliances share the line. If the Cadet is paired with an indirect tank, that piping and its controls are wired in during the same visit, along with system flushing and commissioning.
All gas work in BC must be performed by a licensed gas fitter. HeatLand is TSBC-certified, licensed, and insured, and we handle permits, venting, condensate, gas connection, and commissioning together. If you smell gas or your CO alarm sounds, stop, leave the building, and call the gas utility and a licensed technician from a safe location before returning.
Service and maintenance
The Cadet, like all condensing boilers, benefits from annual professional maintenance. A typical service includes inspecting and cleaning the heat exchanger and burner, checking the condensate trap and neutralizer, verifying combustion, confirming safe venting, and reviewing system pressure and controls. Keeping the condensate path clear is important, since blockages can trigger faults.
System water quality and cleanliness support long-term heat-exchanger health. If the Cadet is paired with an indirect tank, that tank and its controls are checked at the same appointment.
HeatLand services Lochinvar and all major boiler brands. As a family-run company serving Greater Vancouver and the Fraser Valley since 1999, we provide scheduled maintenance and diagnostics for the Cadet. Regular service keeps the boiler running safely, protects its efficiency, and helps you avoid a breakdown during winter’s coldest days.

Frequently Asked Questions
Is the Cadet good for small spaces?
Yes. The Cadet is a compact, wall-mounted boiler designed for installations where floor and wall space are limited, such as condos, townhomes, and smaller houses. Its small footprint is a key advantage. HeatLand can confirm it fits both your space and your home’s heating load.
Can the Cadet heat my domestic hot water?
The Cadet is a heat-only boiler, so it’s typically paired with an indirect tank to supply domestic hot water. This keeps heating and hot water as separate, independently serviceable components. HeatLand can size and integrate the right indirect tank for your household’s needs.
How does the Cadet compare to larger Lochinvar boilers?
The Cadet targets residential loads and compact spaces, while larger Lochinvar boilers like the FTXL serve bigger homes and light-commercial buildings needing more capacity. The right choice depends on your heating load and space. HeatLand runs a proper assessment so you get an appropriately sized unit.
What should I do if I smell gas?
Stop, leave the building immediately, and from a safe location call your gas utility and a licensed gas technician. Do not operate switches or flames, and treat a sounding CO alarm the same way. Never attempt gas repairs yourself; all gas work in BC requires a licensed fitter.
