Domestic Heating

Boilers that are over ten years old waste a lot of valuable energy, in terms of cost and environmental impact. Many older boilers convert as little as 60% of the fuel they use into heat.

If you decide to install a new boiler in the place of an old energy-inefficient one, you can expect to save some money on your gas bills. The boiler installation costs or boiler replacement costs are likely to be significantly outweighed by the savings you are in line to make.

Using the latest technology available, modern condensing boilers improve efficiency to over 90% which could save you up to 30% per year on your home heating bills, which represents a huge saving over the lifetime of your boiler.

Depending on your heating and hot water demand there are different types of  domestic heating boilers and domestic heating systems that Baileys can provide, depending on what type will work best in your home.

As you can see, there are many different considerations and options when choosing the right heating system for a home. Efficiency, heat output, size, storage and of course, cost.This is why it’s important to discuss your options with our experts before making any decisions.


Your boiler may be the single most important item in your home, particularly around winter, and it's common around this time for old or poorly maintained systems to fail resulting in repairs that needlessly add to the cost of maintaining your home.

When it comes to considering a boiler replacement, it's essential to make sure you get it right.

A system boiler, just like a regular (conventional) boiler works on the principle of stored hot water. However, a system boiler differs from a regular boiler in some important respects.

Firstly, many of the major individual components of the heating and hot water system are built into a system boiler, which means that installation is quicker, neater, easier and more efficient.

Secondly, the hot water is pumped from the system boiler through the heating system to the radiators and hot water cylinder, resulting in a fast response and more economical running costs. The system boiler removes the need for a feed and expansion cistern.

System Boiler Installations

Regular Boiler installation

Regular boilers (also known as ‘conventional’ boilers) heat your central heating system directly and produce hot water for your cylinder.

If you are replacing an older model of boiler, the chances are that you will have a regular boiler.

A typical regular boiler system incorporates a boiler, extended controls, a hot water cylinder which is often fed by a cold water storage cistern located in the loft and a feed and expansion cistern - also located in the loft.

Combi (combination) Boiler Systems

A combi boiler is an ingenious space-saving idea, and an increasingly popular choice in UK homes. In fact, combis now account for well over half of all the new domestic boilers installed in Britain every year. It is both a high-efficiency water heater and a central heating boiler, combined (hence the name) within one compact unit. Therefore, no separate hot water cylinder is required, offering space saving within the property.

Also since there is no cylinder or tank in the roof space, this means less pipe work and a shorter installation time.

Further benefits of a combi boiler includes hot water being delivered through your taps or shower at mains pressure. So you can enjoy powerful showering without the need for a pump.
