Warm up your home with one of our high efficiency boilers!
One of the greatest benefits of this type of heating system is that it is divided into zones allowing you to heat different parts of your home while controlling the temperature with different thermostats. If you don’t often use your home office during winter months, you don’t have to waste energy by heating it. Since boilers do not circulate air, they are allergy-friendly because they do not move dust around your home unlike an air system.
Boilers are a very versatile heating option. They can be customized for a variety of different applications and functions. A boiler system can be very complex and requires proper design and installation along with regular maintenance.
How a Boiler Works
Boilers are special-purpose water heaters. While furnaces carry heat in warm air, boiler systems distribute the heat in hot water, which gives up heat as it passes through radiators or other devices in rooms throughout the house. The cooler water then returns to the boiler to be reheated. Hot water systems are often called hydronic systems. Residential boilers generally use natural gas or heating oil for fuel.
In steam boilers, which are much less common in homes today, the water is boiled and steam carries heat through the house, condensing to water in the radiators as it cools. Oil and natural gas are commonly used.
Instead of a fan and duct system, a boiler uses a pump to circulate hot water through pipes to radiators. Some hot water systems circulate water through plastic tubing in the floor, a system called radiant floor heating. Important boiler controls include thermostats, aquastats, and valves that regulate circulation and water temperature. Although the cost is not trivial, it is generally much easier to install “zone” thermostats and controls for individual rooms with a hydronic system than with forced air. Some controls are standard features in new boilers, while others can be added on to save energy.
As with furnaces, condensing gas-fired boilers are relatively common, and significantly more efficient than non-condensing boilers (unless very sophisticated controls are employed).
Most Fuel Efficient Boilers
An ENERGY STAR certified boiler, fuelled by gas uses 10% less energy, fuelled by oil uses 4% less energy, on average, than a standard model. Space heating represents 63% of your home energy use and offers the most potential for cutting your energy bill.
