Finding the right type of condensing boiler

Condensing Boilers

Condensing Boilers

Contact Home Cure Boiler ServicesCondensing boilers were introduced to the UK domestic market around 20 years ago and are the most highly efficient boilers available. A Condensing Boiler recycles flue gases that would normally be wasted, meaning that less energy is required to power your boiler, and as a result reduces carbon emissions and will significantly reduce fuel consumption costs.

Reports state that every year a condensing boiler could save up to 1.7 tonnes of carbon dioxide and for this reason condensing boilers must now be fitted by law. In some cases they can improve efficiency up to 90%.

There are different types of condensing boilers which can be installed into a residential property, the main ones are Combi, System and Regular. There are some differences between types however and who they will benefit which will need serious consideration when deciding to renew.

Combi Boilers

The combi boiler is by far the most popular choice of boiler in the UK, especially within the domestic sector; it’s small and, as the name suggests, combines two elements into one compacted unit; central heating and high efficiency water heating.

As well as space savings this model makes significant savings on hot water costs because hot water is delivered through taps and showers at mains pressure, taking away the need for a pump. The boiler is easy to install, requiring less time, and as no tank is required there is no extra pipe work, therefore further cost savings should be made on installation.

Regular Boilers

Regular boilers heat the central heating system directly and produce hot water for the cylinder; this was once the more popular choice and will be more common in older buildings where the system has not been updated.

There are many more parts to a regular boiler, and so it takes up more space. It has a feed and expansion cistern and a cold water storage system located in the loft, which feeds a hot water cylinder, plus a main boiler itself and extended controls.

System Boilers

A system boiler heats the central heating system directly and produces hot water from a cylinder, just like a regular (conventional) boiler, and works on the principle of stored hot water.

There are some important aspects from which a system boiler differs to a regular boiler. The installation process of a system boiler is easier, quicker, neater and more efficient due to many of the major individual components of the system being built into the boiler.

The boiler has a fast response and more economical running costs than other types of boiler, this is due to the hot water being pumped through the heating system to the radiators and hot water cylinder from the boiler.

An experienced and qualified plumber will always be able to talk you through the pros and cons of boiler types and advise you on what is best for your property when deciding to renew or replace one.

At a glance you will note that Combi boilers are best for cost effectiveness and space saving. This also makes them the most popular choice, but with bigger properties and more people their performance is affected.

Regular boilers were once more popular, but being larger and more expensive to repair they have been surpassed.

System boilers are noted as best for dealing with larger demands, like a three plus bedroom property, as they can deal with multiple functions at once without affecting the volume or temperature of the water supply.
