Combi Boilers: Pricing, Service, Maintenance

In the bustling regions of Greater Vancouver, including Vancouver, Burnaby, North Vancouver, New Westminster, Port Moody, Pitt Meadows, Abbotsford, Langley, Richmond, Port Coquitlam, Coquitlam, Surrey, West Vancouver, Delta, Maple Ridge, and White Rock, homeowners and businesses increasingly favor combi boilers for their efficient heating and hot water solutions. At ROMA Heating & Cooling, we offer comprehensive services for a variety of top combi boiler brands and models, ensuring your setup is optimized for comfort and cost-efficiency.

What is a Combi Boiler?

A combi boiler, or combination boiler, is a high-efficiency water heater and a central heating boiler, combined within one compact unit. This means it heats water directly from the mains when a tap is turned on, eliminating the need for a separate hot water storage cylinder or cold water storage tank. They are particularly ideal for small to medium-sized houses and flats due to their compact size and lower energy consumption.

Pricing and Installation Costs

The cost of a new combi boiler, including installation, can vary widely based on the brand, model, and the specifics of your home’s setup. On average, the price range in the Greater Vancouver area falls between CAD $3,000 and $5,000, with high-end models potentially exceeding this range. At ROMA Heating & Cooling, we\’re proud to offer a 15% discount on these prices, making it more affordable to upgrade or install a new system.

Service and Maintenance Costs

Regular service and maintenance are crucial for ensuring the longevity and efficiency of your combi boiler. At ROMA, our standard maintenance visit costs approximately CAD $150 to $250, depending on the complexity of the service. This includes checking for leaks, assessing the boiler’s pressure, cleaning key components, and more.

Installation Costs

The cost of installing a new combi boiler can vary significantly based on several factors including the brand, model, and specific installation requirements of your property. Here\’s a breakdown of typical costs:

  • Standard Combi Boiler Installation: Prices generally range from CAD $3,000 to $5,000. This includes the cost of the boiler and labor.
  • High-Efficiency Models: More advanced or high-efficiency boilers may cost between CAD $5,000 and $7,000.

Signs You Need Repairs or Service

  • Unusual Noises: Banging, whistling, or gurgling noises can indicate air in the system or a pump failure.
  • No Heat or Hot Water: The most obvious sign something is wrong.
  • Leaks: Any form of leakage is a sure sign that something is not working properly inside your boiler.
  • Pressure Loss: Frequent loss of pressure might suggest a leak in the system or a faulty pressure relief valve.
  • Thermostat Issues: If your thermostat is inaccurate or turning the heating on/off when it shouldn’t be, it may need replacing.

Unusual Noises

Unusual noises from your boiler, such as banging, whistling, or gurgling, can be alarming and are often indicative of underlying issues:

  • Banging Sounds: Often referred to as \”kettling,\” these noises can be caused by a buildup of limescale or sludge on the boiler’s heat exchanger. The restricted flow causes water to overheat, steam, and then expand, creating a banging noise.
  • Whistling Sounds: Commonly known as \”boiler whine,\” this noise is typically related to air within the system. It could also be due to low water pressure or a flow rate that\’s too high, forcing the boiler to work harder.
  • Gurgling Noises: These sounds can occur if air is trapped in the system or the boiler is operating with a frozen condensate pipe, particularly during cold weather.

No Heat or Hot Water

The lack of heat or hot water from your combi boiler can disrupt your daily routine and is a clear sign that your boiler needs immediate attention:

  • Ignition Failures: Failure to produce heat or hot water could be due to ignition issues, meaning the boiler is not lighting to heat water.
  • Valve Failure: A valve or pump not circulating water properly could also lead to heating failures.
  • System Resets: Sometimes, simple system resets or thermostat adjustments can resolve minor issues, but persistent problems require professional diagnosis.


Any form of leakage from your boiler is a critical issue that needs prompt resolution to prevent further damage to the boiler or your property:

  • Pressure Valve Leaks: If the boiler’s pressure valve is leaking, it might be due to excessive pressure inside the boiler.
  • Pump Seal Leaks: If the leak originates from the pump seal, it might indicate that it has become worn out and needs replacement.
  • Corrosion: Pipework or the boiler itself might be leaking due to corrosion, which is a sign of aging or poor maintenance.

Pressure Loss

A drop in pressure can affect your boiler’s ability to heat your home efficiently:

  • Leaks in the System: Even small leaks can cause significant drops in pressure over time, which affects the overall efficiency of your heating system.
  • Faulty Pressure Relief Valve: If the pressure relief valve is faulty, it may release water and thus lower the system’s pressure.
  • Radiator Issues: Sometimes bleeding radiators can inadvertently cause pressure to drop if not topped up correctly.

Thermostat Issues

The thermostat plays a crucial role in regulating your home’s temperature and ensuring your boiler operates efficiently:

  • Inaccuracy: If the thermostat is giving inaccurate readings, it could cause the boiler to turn on and off irregularly.
  • Age and Wear: Older thermostats may lose their efficiency over time and may require recalibration or replacement.
  • Connection Issues: Wireless thermostats could suffer from connectivity issues, which may disrupt communication with the boiler.
