How does the boiler work?
While looking for the best gas boilers for home heating you should know how do they function actually. If we talk about functioning from outside you will just have to switch on and adjust the thermostat according to your need and the thermostat will do the rest of the work. If we talk about its internal functionality, here are some points to clear that.
- Small jets help in entering natural gas in the combustion chamber.
- The burner is lighted because of an electric ignition system.
- There’s a heat exchanger in the boiler through which the flame runs. The hydronic system is connected to it through which water flows in the house.
- The flames provide beat energy to the heat exchanger and in turn heats the water.
- The water is pushed through the hydronic system through electric pumps.
- The water circulates through every heat emitter or radiator entering through one and exiting through the other.
- The water starts to cool as the radiator starts to lose the heat and then the water goes back to the boiler to get heat.
- The temperature is monitored by a thermostat and it automatically turns the boiler off when there is enough heat in the room. And it switches on the boiler when the room is cold.
Types of boilers
There are five types of boilers namely
- Gas Atmospheric Cast Iron Boilers
- Oil Atmospheric Boilers
- Gas Condensing Boilers
- Electric Boilers
- Condensing Combi Boilers
1. Gas Atmospheric Cast Iron Boilers
Natural gas or propane (depending on their availability) is used in the functioning of these boilers. Before buying the best gas boilers for home heating that function through gas, you should check the availability of these gases first.
2. Oil Atmospheric Boilers
You will require heating oil to make Oil Atmospheric Boilers work. However, the operating costs will be affected due to changes in oil prices.
3. Gas Condensing Boilers
Water vapors are condensed into the exhaust gases. This process is done by gas condensing boilers to retrieve the lost heat of vapors which would have been wasted otherwise.
4. Electric Boilers
Electric Boilers use electricity instead of gas to function. They might be an efficient option but not economical.
5. Condensing Combi Boilers
Condensing Combi Boilers can perform two things at once. You will not need a storage tank to deliver water to your kitchen and bathroom as it does it directly.
