Hydronic Heating Specialists Serving Surrey
A boiler that loses pressure overnight, kettles with banging noises, or leaves half your radiators cold is not something a general HVAC technician should guess at. Boiler systems require hydronic heating expertise that most forced-air companies do not have. Eaton's Heating provides same-day boiler repair across all Surrey neighborhoods from our Coquitlam base. We service conventional cast-iron boilers, modern wall-hung condensing units from Navien, Viessmann, and Bosch, and combi systems that handle both space heating and domestic hot water. Every service call starts with a flat-rate $189 diagnostic. Additional work is quoted upfront before we proceed. All parts are CSA certified OEM components backed by a six-month warranty.

Most HVAC companies in Surrey focus on forced-air furnace and heat pump systems. Hydronic heating is fundamentally different. Boilers, radiators, in-floor heating loops, zone valves, expansion vessels, and circulator pumps require technicians who understand water pressure management, circulation dynamics, air elimination, and combustion tuning. Sending a furnace technician to diagnose a boiler problem usually results in misdiagnosis and wasted money. That is why Eaton's Heating has built hydronic heating as a core specialty for over two decades.
Surrey's boiler inventory is concentrated in two segments. Older established homes in areas like South Surrey, Panorama Ridge, and parts of Newton sometimes have conventional cast-iron boiler systems paired with radiators or baseboard convectors that have been running for 20 to 30 years. These systems require careful handling because original piping and radiator valves are difficult to source and aggressive troubleshooting can create new leaks. The second segment is newer or renovated homes with modern condensing boilers and radiant floor heating, where the diagnostic challenges are electronic: error codes, flow sensor faults, condensate management, and communication between the boiler and zone controllers.
Vancouver's damp coastal climate is particularly hard on boiler systems. Moisture accelerates corrosion on older cast-iron components and piping. Condensate lines on modern condensing boilers are prone to blockages in humid conditions. The long heating season means wear accumulates faster than in drier climates. We regularly repair low water pressure and expansion vessel failures, circulator pump failures and zone valve faults causing uneven heating, kettling caused by scale buildup or low flow, ignition failures, condensate drain blockages, and leaking pressure relief valves.
We are a FortisBC Trade Ally, BBB A+ rated, and Technical Safety BC licensed under LGA0200006 with over 20 years of boiler repair experience across Greater Vancouver. Our 400+ five-star Google reviews and 4.9 average rating reflect the trust homeowners place in us for this specialized work. Our technicians stock common boiler parts on their trucks and verify every repair with pressure checks, combustion analysis, and flow verification before leaving. When a boiler is beyond cost-effective repair, we provide honest guidance and a clear comparison with modern replacement options.
For Surrey homeowners whose boiler has failed completely and who need heat restored quickly, we offer same-day emergency dispatch. We also service furnaces and all other HVAC systems across Surrey from our Coquitlam base.
Boiler systems in Surrey homes range from 30-year-old cast-iron units with original radiators to modern Navien combis installed in recent renovations. The diagnostic approach is different for each. On older systems, we check expansion vessel pre-charge pressure, test circulator pump operation, inspect zone valve actuators, and verify that air has been properly eliminated from all heating loops. On modern condensing units, we interpret error codes, test flow sensors and thermistors, verify condensate drainage, and confirm the system is firing within manufacturer specifications.
Whether your boiler heats radiators, in-floor loops, or both, Eaton's Heating has the hydronic expertise to diagnose and fix it. For homeowners considering upgrading an aging boiler to a modern high-efficiency system, visit our rebates page for information on FortisBC incentive programs that can offset the cost. We also install heat pumps for homeowners looking to move away from hydronic heating entirely.

Yes. We offer same-day boiler repair across all Surrey neighborhoods. Our technicians carry common boiler parts on every truck and are dispatched from our Coquitlam base, typically reaching Surrey within 30 minutes via Highway 1. No-heat emergencies are prioritized. Call (604) 535-8434 to book.
The most common causes are a leak somewhere in the system (radiator valves, pipe joints, or the boiler itself), a failed expansion vessel that can no longer absorb pressure changes as water heats and cools, or a pressure relief valve that is discharging due to excessive pressure. A slow leak may not be visible because water can drip behind walls or under flooring. If you are topping up the boiler pressure more than once a month, there is an underlying issue that needs professional diagnosis before it causes water damage.
Kettling, a rumbling or banging sound from inside the boiler, is typically caused by limescale buildup restricting water flow through the heat exchanger, a failing circulator pump reducing flow rate, or air trapped in the system. The restricted flow causes water to overheat locally inside the heat exchanger, creating steam bubbles that collapse and produce the noise. Left unaddressed, kettling accelerates heat exchanger wear and reduces efficiency. We diagnose the specific cause and resolve it during a single service visit.
If your boiler is under 12 years old and the repair involves a standard component like a circulator pump, zone valve, or ignition part, repair typically makes sense. For boilers over 15 to 20 years old, those with cracked heat exchangers, or those operating below 85 percent efficiency, upgrading to a modern condensing boiler can reduce heating costs by 20 to 30 percent. We present both options with transparent pricing so you can make an informed decision. Learn more about boiler replacement options.
Every service call starts with a flat-rate $189 diagnostic fee. If additional repair work is needed, we quote the full cost upfront and you approve it before we start. Costs vary depending on the failed component and boiler type, but common repairs like zone valves, circulator pumps, and ignition components are typically in the $200 to $800 range on top of the diagnostic. All repairs use CSA certified OEM parts backed by our six-month parts and labour warranty.
We service all major boiler brands including Navien, Viessmann, NTI, Bosch, Weil-McLain, IBC, and more. This includes conventional cast-iron systems, modern wall-hung condensing boilers, and combi units that provide both heating and domestic hot water. Many Surrey homes with boiler systems have older Weil-McLain or IBC units that we see regularly.
