Boilers at Plumb Arena

At Plumb Arena we supply a huge range of high quality reliable boilers sourced from the very best manufacturers, at the best possible price. We are committed to energy savings and reducing environmental impact and our range of boilers are all high efficiency condensing models.  All of our boilers have undergone rigorous safety performance testing and are assured to provide you with a warm and comfortable home, and a plentiful supply of hot water throughout the year.

Choosing a new boiler can be a tricky process and at Plumb Arena, we are here to help. When it comes to boilers, there’s no one-size-fits-all solution and your ideal boiler will depend on a number of factors such as the size of your home and family.


How much heat and hot water you and your family use each day will have a huge bearing on what kind of boiler you need. It’s essential to have the right boiler as it will not only meet your needs, but save you money.

If you are looking for a high efficiency boiler, then a condensing boiler is your best bet. Condensing boilers actually use flue gases to recover more heat which other non-condensing boilers waste. The gases are effectively recycled and this cuts down on the amount of energy required to get your boiler firing. So not only will you save on your energy bills with a high efficiency condensing boiler, you’ll also do your bit for the environment too.

Once you start looking at the different types of boilers available, it can be difficult to get your head around. We hope our boiler guide will help make things a little bit easier when it comes to choosing the right boiler for your home.

SEDBUK Energy Efficiency Ratings

All heating boilers offered by Plumb Arena have been through a rigorous testing regime under the governments Energy Efficiency Best Practice Programme.  With the co-operation of boiler manufacturers, and provides a basis for fair comparison of the energy performance of different boilers.

SEDBUK is a term which represents the average annual efficiency achieved in typical domestic conditions, making reasonable assumptions about pattern of usage, climate, control, and other influences. It’s calculated from the results of laboratory tests together with other important factors such as boiler type, ignition arrangement, internal store size, fuel used, and knowledge of the UK climate and typical domestic usage patterns.

Combination Boilers

Combination boilers – or combi boilers as they are becoming more commonly referred to as – are a cost effective way to heat your home and water. Effectively, a combi boiler is an on-demand method in that it does not involve any storage, rather it heats the cold water instantly from the mains, giving you hot water and heat just when you need it.

A combi boiler has the added benefit of providing you with mains pressure hot water, meaning to there’s no need to install a pump for a mains-operated shower.  No storage tank means you will save on space in your loft too and also reduces the risk of leaks and burst pipes.

Combi boilers are proving increasingly popular due to their high efficiency. Because you only switch the heat and hot water when you need it, you aren’t paying for water you don’t need.  Larger homes and families may require a combi boiler which has high flow rate and heat output, while those living in smaller properties may only need a more compact version.

At Plumb Arena, we supply a great range of boilers for our customers from trusted brands such as Worcester, Vailliant, Potterton, Ideal, Glow-Worm and Baxi.

Regular and System Boilers

Many older properties will most probably contain heating systems which use regular or system boilers.  If you are looking to replace an older model such as one of these, Plumb Arena have a wide range to choose from.

Regular boilers are also referred to as conventional boilers or open vented boilers. The boiler provides central heating and hot water through a separate hot water cylinder. This is usually found in a an airing cupboard and is itself fed by one of two feeder tanks which contain cold mains water. Most homes will have their cold water feeder tanks in the attic and there’s normally one for hot water and one for central heating.

One of the main advantages of a regular boiler is that it can supply hot water to a number of different outlets throughout the home at the same time. 

System boilers work in much the same way in that they heat the home and water separately. However, system boilers are slightly more compact than regular boilers in that they have components such as the modulating pump and expansion vessel built in whereas conventional boilers do not.

Of course, hot water cylinders and feeder tanks take up space, but if you are looking to replace an existing system, we recommend you consider the regular and system boilers made by Worcester, Vaillant, Glow-Worm, Ideal, Baxi and Potterton which are available from Plumb Arena.

The type of boiler you have isn’t the only aspect which will affect how efficient it is. The means by which your boiler is powered will also have a huge bearing on the cost.

Electric Boilers

For those seeking increased efficiency, then an electric boiler is a good option. Check out our range of Potterton Gold Electric Boilers to find one to suit your need. A electrically powered boiler is cleaner as there is no flue involved and no fuel, such as gas or oil. That means there won’t be any heat loss and you won’t have to pay a gas company or fill an oil tank. However, if you are using electricity to heat your home and hot water, as well as the many other things in your house which require electricity, then your electricity bill will end up being more expensive.

Back Boilers

A back boiler is usually found within a brick built chimney breast and can be solid fuel or natural gas / LPG.  Solid fuel back boilers are open or closed fronted fires and gas fired back boilers have a gas fire sitting in front of the boiler on a hearth.  When the boiler is turned on, the compact back boiler provides heat for a traditional hot water cylinder.

Many older properties may already have a back boiler, but if you want to install one, make sure you contact an installer who is Gas Safe (formerly Corgi) Registered.  Installation will involve the boiler itself, and possibly a tank and water cylinder.  Modern Baxi back boilers are now available as gas fired condensing back boilers.

Natural Gas Boilers

Natural gas boilers are powered thanks to mains-supplied gas. The type of gas piped into the boiler is largely methane – or Natural Gas. Gas boilers have become very popular because of the convenience of mains-fed gas, which means the fuel isn’t stored at home, and a number of different suppliers providing keen competition in terms of pricing.

However, mains gas isn’t available everywhere in the UK, so this option isn’t open to all. If you are thinking of having a gas boiler installed, you should only deal with a Gas Safe Registered Installer.

LPG Boilers

For those unable to access mains-supplied, an LPG (Liquid Petroleum Gas) boiler may be an option. These kinds of boilers are operated thanks to an external refillable LPG cylinder which is piped into the boiler. Natural Gas boilers can be converted into LPG boilers but again, this type of work should only be carried out by Gas Safe Registered Installers.

Oil Boilers

Oil boilers are another alternative for those who don’t have the option of mains-fed Natural Gas. The oil is stored in a large tank outside the house and piped into the boiler.  The tank is filled whenever more oil is need and because you aren’t tied to one supplier, you can always shop around when it’s time for a refill.

In terms of efficiency, there’s little between oil boilers and gas boilers, although oil boilers do produce more CO2 emissions than their gas counterparts, making a bit more harmful to the environment.  As with most boiler installation, oil boilers can only be fitted by certified installers. In this case, they must be OFTEC registered.
