Finding out which central heating system you need for your property can be hard work. Especially with all the different types of boilers on the market from system boilers, regular boilers and combi boilers you can easily get confused with all of the jargon out there. Here at Direct Heating Supplies we want to make buying your central heating system a seamless and easy process so we have put together a useful guide to help you choose which boiler is best for you and your home. 

What are your choices?

 Properties require different heating requirements depending on the existing setup and demand of those that live there. If you are looking to buy a new boiler it is therefore important that you know which type of boiler will work in your home. Our handy guide below outlines the types of boilers available so you can establish which one you need to suit the requirements of your property.  


What is a Combi Boiler?

A combination boiler, commonly referred to as a combi boiler, combines the functionality of heating your property and generating hot water from the one boiler unit.

Combi Boilers are a popular choice in homes where space is limited. This is because a combi boiler does not require the use of a hot water cylinder or cold-water tank. With less appliances to install around the home, this frees up more valuable space, most combi boilers are known to fit within the standard 300mm kitchen cupboard, out of sight and mind. Ever wondered how such a compact system delivers both heating and hot water? Read on to see how they work …

Combi boilers work as part of a closed hot water system and heats water as it flows past a heating component within the boiler. This water is then distributed around the property to your showers and taps using the mains water pressure. Combi boilers provide hot water upon demand and the performance levels are only compromised if multiple hot water outputs are using mains water pressure at the same time i.e. running a hot bath and hot kitchen tap at the same time may affect the levels of heat and reduce water pressure. With a wide range of combi boilers available today it can be hard choosing one that is best suited to your home. The key things to look when purchasing your combi boiler is the warranty, the longer the warranty the better, so you know your combi boiler is covered for years to come. Secondly, look out for the boilers central heating output, this dictates how much energy the boiler can generate to keep your home warm, furthermore, look out for the hot water flowrate, this dictates the level of power at which the water can be distributed around the property. If your still feeling unsure to which combi boiler is best for you and your home, seek advice from a Gas Safe registered engineer who can then attend your property and give you expert advice for your needs and circumstances.

What is a Regular Boiler?

Regular boilers, also known as a ‘conventional’ or ‘heat only boilers’, are traditional in older properties across the UK and are commonly located in loft spacing as they require more space due to the use of a hot water cylinder and cold-water cistern. A regular boiler generates the heat for your central heating system directly but the hot water that is produced is stored in a hot water cylinder until it is needed. This stored supply of hot water is then drawn upon when hot water is required in the water outlets such as your kitchen and bathrooms. A typical regular boiler system will include a boiler, heating controls, a hot water cylinder (often fed by a cold-water storage cistern) and an expansion cistern. A heating engineer will be able to recommend the exact items you will need to replace if you are looking to upgrade your regular boiler system. Thinking of purchasing a regular boiler for your home?

What is a System Boiler? 

A system boiler is similar in some ways to a regular boiler in that 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. One of the main differences between a system boiler and a regular boiler is that a system boiler has been designed to make installations much quicker and more efficient as many of its components are built into the boiler itself. Unlike a regular boiler, a system boiler does not require a feed and expansion cistern as the hot water is pumped directly from the system boiler to the radiators and hot water cylinder. This makes a system boiler more efficient and inexpensive compared to a regular boiler. If you would like to purchase a system boiler, Direct Heating Supplies offer a wide range in multiple heating outputs to suit your home, view the full range here.
