Generally, there are three types of boilers in the hot water heating industry they are,
The system and the regular boiler need tanks and take water from the mains, store it, warm it, and release it to the user. They take a lot of time in heating the water and one must also compromise with the quantity of hot water with regular maintenance costs and high hot water bills every year.
One the other hand the combination boilers start heating the water directly from the mains and provide instant hot water when a person opens a tap. The combination boiler is cheap and also has a good market value on re-selling as it demands less maintenance repairs unlike the system and regular boiler.
The combination boilers heat the burner with gases like LPG, oil, or other combustion gases. Inside the non- condensing boilers, the gas flew away and waste and demand fuel on regular usage. The regular changing of gases inside a non-condensing combination boiler can add to the cost of the user.
On the other hand, the condensing boilers prevent the gas loss and recycle the gas inside the unit which demands fewer changes in the volume of gases on regular halves and can help the user to add a little more on savings every year.
The gas combination boilers
Many people who have their homes connected with the natural gas pipelines prefer the natural gas combination boilers as they help in saving money and gas.
The oil combi boilers
The oil combi boilers are one of the popular choices among the homes that lack gas connectivity. It is compulsory to have an oil tanker stack up with a pipe to the boiler to fill it when the boiler runs out with oil.
LPG combination boilers
The expanding form of LPG is Liquefied petroleum gas and we can call it a mixture of oil refining and natural gas and also a small portion of hydrocarbons involves in the preparation of LPG. Their working method is same as the oil combi boilers
Electric combi boilers
The electric combi boilers find their applications in places where there is zero connectivity to oil or natural gas. The electricity is used to heat the water and it can add upon costs if used for larger homes.
