System Boiler vs Combi Boiler Running Costs?

A boiler is one of the most important appliances in a modern house or other types of buildings that help human beings continue life per routine in the coldest of winters. Boilers help produce the energy that is essential to keeping residential and commercial buildings warm and operating at temperature that is suitable for continuing daily house and office work.

As the name suggests, the boiler is just that: a boiler. The primary function of a boiler is to warm water to a temperature that helps a building’s heating system function. The heating system is used in two primary ways. The first is to supply warm water around the property for use in routine activities ranging from washing and cleaning the dishes to bathing and doing the laundry. The second of the boiler’s usage is its ability to provide heat to a property.

Once the boiler heats the water, the water is moved around the house through a network of pipes and taken to radiators, which distribute the heat energy in the room and make it warmer. Radiators are made up of a number of metal tubes or fins that transfer the heat contained by the water boiled by the boiler into the room.

System Boiler vs Combi Boiler

Boilers and boiler types

A traditional boiler essentially consists of a heating chamber and an insulated water tank used to store hot water. The water in the boiler tank gets heated by burning various kinds of fuels, including gas, oil, and wood. However, many modern boilers are generally powered by electricity and even solar energy. 

Boilers can be of various sizes and specifications that can suit a building’s hot water and heating needs. There are several types of boilers and can be differentiated on the basis of the type of mechanism they employ to generate heat or the kind of energy they utilize. One of the most common types of boilers is the gas boiler, which is powered by natural gas. Then there are oil-based boilers, electrical boilers, and even solar boilers, each differing from the other slightly.

System boiler vs Combi boiler

Modern boilers used in homes across the country can be classified as either combination boilers, commonly known as combi boilers, or system boilers. A combi boiler is both a high-efficiency water heater and a heating boiler, with the main factor differentiating it from traditional boilers being the absence of a water tank. The combi boiler heats the water directly from the mains and can provide hot water on demand. On the other hand, a system boiler does require a separate cylinder for hot water storage.

System boiler vs Combi boiler running costs

Both system boilers and combi boilers have their own set of advantages and carry varying running costs. Generally, a combi boiler is considered the more efficient of the two, as it operates only when there is a need for hot water. Conversely, system boilers work whenever the temperature of the water stored in the tank falls below the set level. 

However, a combi boiler will lose its competitive edge if there is a greater volume of hot water required in your building. In case the hot water usage is on the higher side, for example in a large house or an office building, a system boiler will prove to be the better choice. A system boiler will not only have a large volume of warm water available for usage, but it will also ensure that there is a consistent pressure of water being supplied in all of the taps and faucets around the building. Combi boilers work best in small spaces with limited water usage.

Ultimately, the running cost for your system or combi boiler will depend on the property size, water usage and pressure, and budget. The best way to opt for a boiler that is best suited to you and your property’s needs is to get in touch with a boiler installation and maintenance expert. An expert will help you make an informed decision about the boiler most suited to you based on your building’s hot water and heating requirements. 

A boiler is a major component in your building that will stay with it for a long time. So take your time before you make a final decision, lest you regret it for years to come.
