Combi boilers

Combination (Combi) boilers have become the most popular selling boiler type for gas central heating in the United Kingdom. They are making them smaller and smaller; not even able to fit them in to integrated cupboards in a kitchen or airing cupboard, they are very economical to run. And because the water is heated directly from the main supply, you don’t have to wait for water to heat up – and your stream of hot water will be continuous.

They are more economical than other types too. Because combi boilers don’t use an external hot water tank, there is no large bulky cylinder to heat first, and you never heat the same water again, if you’ve let it run cold.

But, for that very same reason – the lack of a hot water storage tank – your nice hot shower will be interrupted if anyone else uses the hot water in your home at the same time as you.

 

The right boiler for me?

If you live in a small property, without very many bathrooms, or are short for space then a combi boiler will be the correct choice for you.If you currently have a cold-water tank in the loft but want you would like a loft conversion for an additional room, swapping your old boiler for a combi boiler will eliminate the need for the tank, and free up the space you need for your loft project.

A combi boiler is the only way to have instant, on-demand hot water in your home without the hassle of having to wait for the water tank to be heated and you’ll also get drinkable water from every tap in the property.


 

Sealed system boilers or unvented heating

A system boiler (also known as a closed or sealed system boiler) works on the principle of stored hot water. This means that you will need an airing cupboard or other space for the hot water storage tank.

Although a tank is needed in the loft or airing cupboard, a system boiler still generally takes up less space than a traditional open vent or heating only boiler, which utilises a second tank in the loft. Also, many of the individual components of the heating and hot water system are built in, which means that installation is quicker, tidier, easier and more efficient.

With a system boiler you can run hot water from a range of outlets all at the same time, without someone else’s shower running cold due to the fact you have the hot water stored ready to use, you will also get good water pressure.

Is this the right boiler for me?

A system boiler is a great choice for the bigger homes or family’s with hot water needs that can’t be met by a combination boiler… You will need a tank in the airing cupboard though.

However, you’ll have to wait for water to be heated when you want it, and it could run out if it’s used too quickly.

Many people with older systems such as open vent boilers choose an unvented sealed system for their central heating and hot water. Although it is more expensive than simply replacing your boiler with the old system, you will be able to free up more space in your home or loft.

Open vent and open vent sealed system boilers

An open vent boiler is the existing system commonly in most people’s homes. This type of system uses two water tanks, both located in the loft, and a hot water storage cylinder in the airing cupboard so it takes up quote a lot of space. One tank draws water from the mains supply and feeds the storage cylinder which, when heated by the boiler, can release hot water to taps all over the property.

The second tank is the feed and expansion tank which contains the correct level of water for your heating system, allowing for water expansion when you turn the heat on.

Showers, taps and running baths can be drawn in any room at the same time, but be aware that if the cylinder should run cold it will take some time to reheat, if there is requirement for use of another full bath it could be a while to wait.

Many people switch from a traditional open vent boiler to an open vent sealed system boiler. This is a relatively cheap switch to make and will cut the need for one of the tanks in your loft.

Is this the right boiler for me?

Because it’s the existing system in many people’s homes, an open vented boiler is inexpensive to replace and making the switch to an open vent sealed system is also relatively cheap. However, both these systems use up loft space. So if you need your loft space for storage or are looking in the future to convert the loft make sure you think of all the options available to you.

Like system boilers, open vent systems allow you to run hot water from a range of outlets at the same time, without the water running cold elsewhere in your house. The water pressure can be very low though, and you’ll only have drinkable water from one outlet (normally the kitchen), because it uses a storage system.

The hot water might also run out, and you’ll have to wait for it to reheat.

Back boilers

Some homes still use back boilers, which in most cases is very large, you’ll find them normally hidden behind a chimney, with a fire front to cover them. If you don’t already have this system then it’s not going to be a first choice for you as the water pressure is generally very low, it is very space-hungry and you’ll need somewhere to hide your boiler.

However, if you do already use a back boiler, then it might be the best option for you when the time comes to replace it.

Traditionally, back boilers are not very efficient, but great improvements have been made over the past 10 years, so by replacing your old back boiler, you could make some major savings on your yearly heating bills.

Is this the right boiler for me?

Back boilers provide reliable heating and hot water, and allow you to draw hot water from more than one source at the same time, without affecting other sources. However, they need a lot of space – the boiler hidden behind your chimney, two tanks in the loft space, and a cylinder in the airing cupboard.

Few people will consider a back boiler unless they already have that system in place as other, newer systems can easily handle the demands of a big home without taking up as much space. But if you already use a back boiler, you’ll save a lot of money by sticking with the same system when the time comes to replace your boiler.
