As a part of our services, we can suggest various types of boilers that are suitable for your home and fit within your budget. One of the frequently asked questions we receive is “what is the ideal boiler for my home?”. Each type of boiler has its pros and cons, and selecting the right one depends on various factors such as the available space in your home, your lifestyle, budget, and other relevant considerations.

There are several types of domestic boilers that are popular in the UK. The most common types include:

  1. Combi boilers: These boilers are compact and provide hot water on demand, making them a popular choice for small homes and apartments.
  2. System boilers: These boilers require a hot water cylinder to store hot water, but they can provide high water pressure and are suitable for larger homes with multiple bathrooms.
  3. Conventional boilers: These boilers require both a hot water cylinder and a cold water tank, but they can provide a high level of hot water output and are suitable for larger homes with higher hot water demand.
  4. Heat only boiler, which is also referred to as a regular, conventional, or open vent boiler, is a type of heating system that consists of two tanks, a hot water cylinder, and the boiler unit. These boilers are commonly installed in larger properties where there is a higher demand for hot water from multiple taps and showers.

The type of boiler that is best for your home will depend on factors such as the size of your home, your hot water needs, and your budget. It is recommended to consult with a qualified heating engineer to determine which type of boiler is the most suitable for your specific requirements.

The distinction between a heat only boiler and a system boiler is in how they maintain pressure and handle water storage. Heat only boilers use a feed and expansion tank to maintain water pressure, while system boilers use a pressurized heating circuit that is topped up with mains water. Heat only boilers also have an external feed and expansion tank, whereas system boilers usually have an internal expansion vessel. Additionally, system boilers require less space and piping compared to heat only boilers, as they do not need tanks and other elements of an open vented system. Both heat only and system boilers store hot water for later use, unlike combi boilers which heat water on demand.

On the other hand, combi boilers heat water instantly on demand and do not store hot water. They do not require a cold water tank, external hot water cylinder, or feed and expansion tank, making them more space-efficient, particularly in properties with limited storage space.

The advantage of a heat only boiler is its ability to supply hot water to multiple taps and showerheads with ease, thanks to the large hot water tank that can store and deliver ample hot water instantly. This makes it a suitable option for larger homes with higher hot water demand.
