Deciding on the best boiler for your home can be a confusion process. You must consider efficiency, property size and lifestyle when choosing a suitable boiler system. If you are looking to buy a new boiler it is therefore imperative that you know which type of boiler will work best in your home.
The guide below outlines the types of boilers available so you can establish which one you need to suit the requirements of your property. We discuss the systems, how they work, their advantages and what kind of homes they work best in.
What is a Combination Boiler
Combi boilers provide both heating and hot water directly from the mains. They are also highly space efficient as there is no need for a separate hot water tank.
Providing the property with instantaneous heating to radiators and hot water supply, combi boilers are not only convenient but highly efficient as they only produce heat when required. This is also great if you’re looking to save money on your heating bills. Combination boilers can also save money during installation as it is not necessary to install a tank in the roof space, meaning less piping and a speedier fitting.
There is a great range of combi boilers to suite any household size. Available in a variety of heat outputs and flow rates, the correct boiler will entirely depend on the number of bedrooms and bathrooms in the property. This is determined by your gas safety registered engineer before installation.
Combination boilers are not suitable for homes which exceed one bathroom as the higher demand will negatively affect performance.
A combi boiler is also unsuitable for homes with multi-jet showers; this is due to an excessive demand for hot water which combi boilers cannot provide. If you have a number of bathrooms, or a pump assisted power shower a system boiler would be more suitable.
What is a Regular Boiler
Regular boilers offer a more traditional heating alternative for the home. Also known as conventional or heat only systems, a regular boiler is commonly found in older properties. These systems require a large amount of space for installation due to the need for a cold water cylinder and cold water cisterns.
Two water cisterns are needed for a regular boiler, one to feed the hot water cylinder and another to manage the water level of the central heating system. This means regular boilers are most suitable for properties with an existing heat only system.
This boiler option is ideal for larger home with a high demand for hot water meaning they are best suited for properties with two or more bathrooms. They are also a the perfect choice for homes where water pressure is low and can reduce your carbon footprint when connected to a solar water heating system.
What is a System Boiler
A system boiler functions in a similar way to a regular boiler system as it provides the heat for your central heating system and produces hot water that is stored in a hot water cylinder until it is needed.
System boilers are designed to make installation quicker. This is achieved through situating many of the components required to provide efficient heating and hot water into the boiler itself. Unlike a regular boiler, a feed & expansion cistern is not required as the hot water is pumped directly from the system boiler.
System boilers are ideal for larger homes with a higher demand for hot water, which makes them perfect for properties with more than one bathroom. This system is economical to run and can supply the property with a constant supply of hot water to any number of taps simultaneously.
