Gas Boilers

Natural gas is currently the most common fuel for fired burners, mostly due to the fact that it is an easily accessible resource and a cheap heating fuel. No matter your radiant system preference, the team at Royal Plus is here to help you improve the energy efficiency of your current home or business.

Benefits of Gas Boilers

• Natural gas is the cleanest burning fuel, contributing to the safety of our environment.
• Natural gas is an abundant, natural resource and is a very inexpensive source of energy.
• Gas boilers can operate to heat both your home’s water and air in a single machine.
• With natural gas, there is no storage tank or reserve for fuel.
• Efficient models, such as condensing gas boilers, have an AFUE (annual fuel utilization efficiency) rating of 90% or greater.
• Electric ignition of gas eliminates the need for a pilot light for the duration of the boiler’s operation.
• New combustion technologies allows for more efficient heating without using additional fuel.
• Heating of the air and water occurs more quickly than other heating appliances.

How Boilers work

Gas Boiler – When the thermostat triggers the boiler to heat the house, a valve opens, releasing the natural gas into a combustion chamber in the form of small jets. An electric spark ignites the fuel. The fire heats the water-filled pipes that circulate through your home. The pipes connect to a radiator where the heated water emits heat energy into the room. Once the heat is exhausted into the air, the cooled water returns through the pipes leading back to the boiler to be reheated and circulated again.
