Boilers and Combi-Boilers: Your Questions Answered
What is a Combi Boiler? What is the typical monthly cost?
A Combi boiler, or combination boiler, is a high-efficiency heating solution that functions as both a boiler and a water heater. These units combine both capabilities into a single, compact design. Combi boilers heat water directly from the mains supply when a tap is turned on, thereby eliminating the necessity for a separate hot water tank. This design not only conserves space but also improves energy efficiency by minimizing energy waste associated with pre-heating and storing water. We are leaders in providing affordable and cost-effective HVAC solutions in Ottawa — our competitive monthly plan is priced at just $40, significantly lower than the typical $60–$80 offered by other providers. Contact us for a free, no-obligation quote on installation, purchase, or servicing of a combi boiler.
What are common signs indicating a need for boiler repair and service?
Common indicators that your boiler may require repair include uneven heating, unusual noises, a decrease in water pressure, or frequent extinguishing of the pilot light. If you notice any of these symptoms, we highly recommend giving us a call for a professional boiler repair service. We also offer a complimentary second opinion on major repairs or replacements — no pressure, just straightforward professional advice.
What are the signs that my boiler requires replacement?
Signs your boiler may need replacement include being over 15 years old, frequent repairs, rising energy bills, inconsistent heating, unusual noises, or rust. Upgrading to a more efficient model can yield significant savings over time, as the energy savings could cover the cost of the upgrade.
What warranty is included with a new boiler?
The warranty on a new boiler depends on the brand, but heat exchangers are usually covered for 10 to 15 years, while parts typically have a 2 to 5-year warranty. We proudly stand behind our work and offer a 10-Year Parts & Labour Warranty for your peace of mind.
What is the cost of a new boiler installation?
Residential boiler installations generally range from $6,000 to $12,000 or more, depending on the type and size of the boiler, the complexity of the installation, and the necessity for new piping. We offer fixed-price quotes following a thorough assessment of your specific requirements. The estimated cost for a straightforward installation of a Canadian-made Glow Brand replacement for an older Flow Max model is between $4,500 and $6,000. We offer a monthly payment plan starting at $40, with interest-free financing and flexible terms up to 12 years, subject to availability.
Do you remove the old boiler? Can you return my boiler to the rental service provider?
Yes — the removal and disposal of your old boiler are included in our installation service. We ensure that the old equipment is properly disconnected, removed, and disposed of in accordance with environmental regulations or returned to the current provider. We leave the area clean and ready for your new system.
How often should a boiler be serviced?
Boilers should be serviced annually. This includes cleaning, safety testing, and component inspection. Regular maintenance prevents breakdowns, maintains efficiency, and extends equipment lifespan. Many manufacturers also require annual service for warranty coverage.
How do I schedule a boiler installation quote?
