Why Surrey 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 Surrey, the typical combi candidate is Clayton/Fleetwood townhomes and South Surrey homes. Surrey’s townhome boom makes it one of the largest combi markets in Metro Vancouver.
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 Surrey 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 Surrey 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 Surrey
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
- You are replacing an aging boiler-plus-tank combination
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 — Surrey
How much does a combi boiler cost in Surrey?
In Surrey, most combi boiler installations run $5,700–$8,800 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. Clayton/Fleetwood townhomes and South Surrey homes 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 Surrey home?
Surrey's townhome explosion in Clayton, Fleetwood and Grandview Heights has made combi boilers the standard heat source for thousands of new units. We are installed across multiple Surrey developments and keep the popular Navien and IBC combi models on the truck for fast turnarounds. 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 Surrey 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.
