Energy-efficient boilers are becoming a popular choice for new buildings

Boilers are heating devices that generate hot water for hydronic, baseboard, radiant heat or steam radiator heating systems. A boiler works using natural gas, oil, propane or electricity to heat water between 70 and 80 degrees Celsius, which is then circulated throughout the pipes in your home or business to keep your space comfortable and warm.
If you have a radiator heating system, the boiler sends the heated water to the radiators, which give off warm air. If you have in-floor radiant heating, the boiler provides the heat source.
Hot water, or hydronic, heating is a newer heating system that uses a circulating pump to move pressure-heated water. The pump is governed by a thermostat and a burner, and an expansion tank containing air and water is mounted above the boiler.
Like most equipment in your home and business, energy-efficiency is a priority when choosing larger appliances like furnaces and boilers. This is why condensing boilers are fast becoming the boiler of choice over traditional boilers. Condensing boilers create larger, more efficient heat exchanges because they can convert up to 98 per cent of their fuel into heat, while older boilers can convert only about 78 per cent. While the cost to replace your old boiler and buy a condensing boiler may be expensive, it will quickly pay for itself and save you money in the long term.
