A Combi boiler, or combination boiler, is a high-efficiency boiler that doubles as a water heater. Combi boilers feature both the boiler and water heater in one compact unit. They heat the water directly from the mains when you turn on the tap, meaning you don’t need a hot water tank. Combi boilers are very cost-effective and energy-efficient options as they do not waste energy pre-heating and storing water.

Limescale is a hard chalky deposit consisting mainly of calcium carbonate that often builds up wherever there is running water. While we are more used to limescale blocking the nozzles of our showers and tap, it has a very serious impact on your boiler’s efficiency. A limescale build-up of just one millimeter can increase fuel consumption by up to 2 percent. To prevent the buildup of limescale in your boiler, make sure you schedule regular maintenance with HVAC professionals.

The culprit for “no heat” from your boiler could be one or more of many factors. It could be a broken or faulty diaphragm or air lock. Perhaps one or more of the motorized valves is wonky or broken. There could be an issue with the thermostat. Low water levels are another issue for boiler heating systems, as a lack of water means the heat can’t be sent out to the radiators. Your best bet is to call on Advanced HVAC if you’re in or near Ottawa and have no heat. We can be out at your home or commercial property ASAP and will assess the situation to determine what’s causing your boiler heat to fail. Advanced HVAC’s friendly and knowledgeable tech teams can get your boiler heat system back up and running quickly so that you and your family or staff can stay warm and comfortable.

Most people nowadays aren’t looking to buy into a boiler system. Newer buildings, especially homes, rely on furnaces and gas heating systems to keep everyone warm and comfortable in the Ottawa and Eastern Ontario winters. Having said that, we do sell and service boilers. If you already have a boiler heating system and need new equipment, talk with Advanced HVAC so we can set you up with a new boiler or other parts. We also have skilled techs to perform repairs on your boiler in Ottawa and nearby communities.

Boiler heating systems are another form of an HVAC system designed to heat a building. Instead of forcing warm air through duct work – which is what a furnace does – boilers use water to distribute heat through a series of pipes and pumps. If you’ve seen a radiator in a house, school or office building, that was probably a boiler system (unless it was a space heater type of device). Radiators give off heat thanks to the hot water that’s inside of them. Cooler water is returned to the boiler to be reheated. Boilers can run on gas or heating oil as a fuel source to heat the water. Boiler equipment includes thermostats, aquastats, valves, radiators and more.
