Having a warm home and readily available hot water in your home or establishment is a necessity today. It is required for a relaxing bath or to make our space comfortable, especially during colder weather. There are various mechanisms available to provide such comfort, but a boiler is the best device to accomplish the job. 

Types of Boiler

There are various types of boilers which differ in the way that they heat water. The use of propane, natural gas, and electricity are the most common types. Boilers can also be conventional, combi-boilers, or a system boiler. The traditional style of boiler heats water and stores it in a water tank before the user requires it. This type is commonly utilized in larger houses as installation requires a significant amount of space. 

On the other hand, smaller home spaces use combi boilers which take up less space because it delivers hot water from the mains without the need for a hot storage tank. However, if a combi boiler could not handle the required amount of hot water, a system boiler is a better option. This type of boiler directly supplies hot water to a storage tank or the radiators. 

Features of a Good Boiler

Whether you are looking to replace your boiler or are thinking of getting one installed, here are some features to look for purchasing a boiler.


Research and compare well-known and reputable brands before purchasing a boiler. There are various options when selecting a boiler, and while it is tempting to settle for modest alternatives, you might want to consider how reliable it is. The cost of repairing a boiler varies hugely depending on the damage or parts that need replacement. Also, consider the cost of workers and skilled engineers who will be fixing your system. Poor judgment on purchasing a low-priced boiler may end up costing you more if repairs are often needed or if the system needs to be replaced.


Another important factor is the range and limitation of the boiler. Before getting a new boiler quote, it is recommended to have some information ready on the usage habits and size of the house. A high volume boiler is required, especially for a household with rapid swing loads. One rule to help decide the boiler capacity is to allocate 25 liters for each person per day. 


A boiler system that can concurrently provide hot water and heating is the norm, which is typically delivered by a network of pipes. Select a system that can promptly provide hot water using lesser power. A four-pipe system is recommended rather than a gravity-fed system as the former produces lower output with lesser energy. Additionally, one must consider the startup time of the boiler. Quicker startup times also signify quick cools down.

Heating Controls

Traditional boilers have limited switches and features for managing temperature. Opportunely today, boilers are now equipped with intelligent zoning controls as well as a timer and temperature programs. Functions can also be managed remotely, with some having or are compatible with mobile applications. Having this feature enables users to control the temperature remotely using mobile devices.

Ease of Maintenance

Cleaning is an integral part of preserving the boiler. Thus, when selecting a boiler, one should consider the ease of blowdown, and in keeping pressure valves clean. A boiler system with small pipes does not fair in this category. Among the other factor to consider are the location for the stack and control panel, feedwater inlet, tube, and burner removal, as well as gas piping maintenance.   

Effective Turndown

An effective turndown is related to the burner’s performance. It can be measured by identifying the lowest fuel and air input that can provide a good combustion efficiency. A boiler with a wide range of controls for turndown levels is great but ensures that combustion efficiency is still maintained.

Required Space

The space needed for the boiler is one factor to be considered. It is better to select a boiler system that occupies lesser space. Vertical type boilers occupy less floor space, yet be mindful that they pose some limitations on output due to its height. The space required for maintenance should also be considered with this factor. 

The factors above are just some of the determinants to consider when purchasing a boiler. It is imperative to identify the usage as well as space where the boiler is to be installed. There are various types, brands, and options to choose, but always consider its quality and efficiency over time. Moreover, ease of maintenance should not be ignored, as this will also accumulate in your expenses.
