Combi boiler ,system boiler?which boiler is right for me?
Choosing the right boiler can be a complicated choice. As well as the cost involved, you have to take into consideration the space available in your home, how much hot water you'll be likely to need and how economic your new boiler will be.
By law all new boilers must now be high-efficiency condensing boilers unless it is too difficult or too expensive to fit one. Condensing boilers capture the heat that is normally lost by traditional boilers and reuses it. This means that a top of the range A-grade boiler could have as much as 96 per cent efficiency.
The process can also be confusing, because different types of boilers are sometimes known by different names ex:combi boiler,system,heat only but we've put together everything you need to know to make the right choice.
Combi boilers
Combi boilers have become the best selling boiler type for gas central heating in the UK. They are small; fitting into cupboards, and very economical to run. And because they heat water directly from the mains, you don't have to wait for water to heat up - and your stream of hot water will be endless.
They are more economical than other types too. Because combi boilers don't use an external hot water tank, there is no cylinder to heat first, and no need to reheat the same water again if you've let it run cold.
However, for this same reason - the lack of a hot water storage tank - your nice hot shower will be interrupted if anyone else starts running the hot water in your home at the same time.
Is a combi boiler the right boiler for me?
If you live in a small house or flat, without multiple bathrooms, or are short for space then a combi boiler will be an excellent choice for you.
If you currently have a cold-water tank in the loft but want to covert your loft space into an additional room, swapping your old boiler for a combi boiler will eliminate the need for the tank, and free up more space.
A combi boiler is the only way to have instant, on-demand hot water in your home without the inconvenience of having to wait for the water tank to be heated and you'll also get drinkable water from every tap.
Sealed system boilers (unvented)
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 airing cupboard, a system boiler still needs 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, neater, easier and more efficient.
With a system boiler you can run hot water from a range of outlets simultaneously, without someone else's showing running cold on them. You will also get good water pressure.
Is this the right boiler for me?
A system boiler is a great choice for a larger home or family with hot water needs that can't be met by a combi boiler, but who want to keep loft space free. 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.
Open vent and open vent sealed system boilers
An open vent boiler is the existing system 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 is very space hungry. 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 house.
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 a little time to reheat.
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.
Like system boilers, open vent systems allow you to run hot water from a range of outlets simultaneously, without the water running cold elsewhere in your house. The water pressure is low though, and you'll only have drinkable water from one outlet, because it uses a storage system.
The hot water might also run out, and you'll have to wait for it to reheat.
Sedbuk's energy efficiency chart
The Sedbuk label is the boiler equivalent of the energy label found on domestic appliances such as washing machines, fridges and dishwashers.
Sedbuk stands for Seasonal Efficiency of a Domestic Boiler in the UK, and has lettered ratings from A to G.
The rating represents the average annual efficiency achieved in typical domestic conditions, making reasonable assumptions about how it's used, the climate, controls, and other influences.
Each letter rating represents a range of percentage efficiencies with A (efficiency of more than 90%) being the best and G (efficiency of less than 70%) being the worst. Conventional boilers are around 66-81% efficient, while condensing boilers are between 85% and 91% efficient.
New building regulations
New building regulations require that only gas boilers with Sedbuk A and B ratings can be installed unless it's too difficult or expensive, in which case an exception procedure must be completed and certified.
Which manufacturer is the best?
Well ,this is really personal choice but we would recommend a german manufacturers as their products are the best engineered and reliable.We highly recommend brands like Viessmann boilers,Vaillant boilers,Worcester-Bosch boilers

How much will it cost?
Installation costs can vary widely depending on the type of system you currently have and the type you would like to replace it with. If you're having a full heating system overhaul, including radiators and heating controls, the cost will go up considerably.
Each system is different and the cost depends on your requirements but we can fit you the best boiler on the market with 5 year parts and labour warranties for the price of very average one.We fitt and supply Vaillant boilers ,Viessmann boilers, Worcester boilers or any other brand availlable on the market
