Why Chilliwack Homeowners Choose Combi Boilers
A combi (combination) boiler handles both your space heating and your domestic hot water from a single wall-hung unit — no separate water heater tank required. In Chilliwack, the typical combi candidate is Sardis/Promontory townhomes and rural farm properties. Chilliwack's residential growth in Sardis and Promontory keeps combi demand rising.
Space heating + hot water in one unit
A single wall-hung appliance handles both your radiators/in-floor heat and your domestic hot water — no separate water heater needed.
Reclaim floor space
Removing a tank water heater (and often an old floor-standing boiler) frees up a closet, a corner of the garage, or valuable mechanical-room space.
Endless hot water on demand
Water is heated as it flows, so you never wait for a tank to reheat — ideal for back-to-back showers in smaller households.
95%+ efficiency
Condensing combi boilers extract heat from the exhaust that older units sent up the flue, cutting gas use versus a 70–80% legacy system.
One warranty, one service visit
A combi consolidates two appliances into one — simpler maintenance, one set of parts, and a single manufacturer warranty to track.
FortisBC rebate eligible
High-efficiency condensing combis qualify for FortisBC and CleanBC rebates when installed by a licensed contractor like us.

Combi Boiler Sizing for Chilliwack Homes
Correct sizing is everything with a combi — undersize it and you run out of hot water, oversize it and you waste gas and short-cycle the unit. Here is how we match combi capacity to Chilliwack homes:
| Home Profile | Recommended BTU |
|---|---|
| Condo / apartment · 1 bath · 1–2 people | 80,000–90,000 BTU |
| Townhome · 1.5–2 baths | 90,000–120,000 BTU |
| Detached home · 2–3 baths | 120,000–150,000 BTU |
| Large home · 3+ baths used at once | Consider a system boiler + indirect tank |
Combi vs. Separate Boiler & Tank in Chilliwack
Choose a combi if…
- You want to remove a bulky tank water heater and reclaim the space
- Your home has 1–3 bathrooms with typical (not simultaneous-peak) demand
- You live in a condo, townhome, or small-to-mid-size detached home
- You want the highest efficiency and FortisBC rebate eligibility

Consider a system boiler if…
- 3 or more bathrooms are regularly run at the same time
- You have large soaker tubs or a high-flow rain shower
- The home is large (2,800+ sq ft) with high simultaneous hot-water demand
- You need to feed multiple dwellings or a suite plus the main house
- An indirect tank or storage system better matches your usage pattern

Combi Boiler FAQ — Chilliwack
How much does a combi boiler cost in Chilliwack?
In Chilliwack, most combi boiler installations run $5,900–$9,400 fully installed, depending on the brand and BTU/GPM size you need, gas-line and venting changes, and removal of the old boiler or water heater. Sardis/Promontory townhomes and rural farm properties make up most of our local combi work. We provide a written, fixed quote before any work starts.
Is a combi boiler the right choice for a Chilliwack home?
Chilliwack's Sardis, Vedder and Promontory townhome growth suits compact combis, while dairy farms and acreages in Greendale and Rosedale need higher-BTU systems for outbuildings. Propane sizing is routine on Fraser Valley farm properties. We assess your hot-water demand, bathroom count and existing heating loop before recommending a combi or a system boiler with an indirect tank — whichever genuinely fits your Chilliwack home.
How much does a combi boiler cost to install in Greater Vancouver?
Most residential combi boiler installations in Greater Vancouver run between $5,800 and $8,500 installed, depending on the brand, the BTU/GPM size, gas-line and venting changes, and removal of the old equipment. Estate-sized or hard-access properties can run higher. We always provide a written, fixed quote before any work begins.
Is a combi boiler a good choice for a BC condo or townhome?
Yes. Combi boilers are wall-hung and need no storage tank, so they are extremely popular in condos and townhomes where mechanical space is tight. A correctly sized combi delivers whole-unit heating plus on-demand hot water from a single appliance.
Will a combi boiler give my home enough hot water?
For homes with 1–3 bathrooms and typical usage, a properly sized combi delivers 3.8–5.5 GPM of continuous hot water — enough for back-to-back showers. Homes that run 3+ bathrooms simultaneously or have large soaker tubs are usually better served by a system boiler with an indirect tank, and we will tell you honestly which your home needs.
Are combi boilers eligible for FortisBC rebates?
High-efficiency condensing combi boilers (ENERGY STAR / high AFUE) qualify for FortisBC and CleanBC rebates when installed by a licensed gas contractor. We confirm current rebate eligibility and amounts as part of your quote and help with the paperwork.
How long does a combi boiler last?
With annual maintenance, a quality combi boiler typically lasts 12–15 years. Hard water, skipped servicing, and poor original sizing shorten that lifespan, which is why we descale, flush, and combustion-tune on every maintenance visit.
Can you convert my old boiler and tank water heater into one combi?
Yes — boiler-plus-tank to single-combi conversions are one of our most common jobs. We remove both old appliances, upsize the gas line if needed, run code-compliant venting, tie into your existing radiators or in-floor loop, and commission the new unit. Most conversions are completed in one to two days.
