There Are Three Main Types of Boilers: Combination, System and Open Vent

Combination Boilers

Combination boilers (combi boilers) are the most popular boilers currently installed in the UK. Combined boilers are units that eliminate the need for a hot water tank and save space in the home because you do not need a drying cabinet and there is no space in the attic. A perfect choice if you're looking for boiler installations in Nottingham and would like your money to go that much further. As its name suggests, combined boilers combine two functions: they not only contain domestic hot water but also boilers for central heating. Mixed boilers operate on demand, which means they provide hot water as needed immediately.

ADVANTAGES OF COMBINATION BOILERS:

  • - Acquiring space
  • - Save money because there is no hot water tank that requires constant heating to keep the water hot.
  • - The water is obtained by taps and other outlets are under pressure.
  • - Smaller pipes are required during installation, so mounting is usually faster.

DISADVANTAGES OF MIXED BOILERS:

  • - Since water reduces the pressure offered by a mixed boiler, "à la carte" is low in pressure, can more openings (taps/ showers/washing machines) simultaneously, depending on its potency boiler

SYSTEM BOILERS

The system boilers (indoor boilers of the system) consist of a fused unit which usually works at about 1 bar of pressure. The system boilers need a storage tank for hot water in front of the building, which is often placed in a drying cabinet.

PROS OF SYSTEM BOILER:

  • - Good for homes with more than one bathroom, because the type of boiler system can provide hot water under the same pressure at the same sales point in different sockets.
  • - You do not need an expansion tank in the attic so you have more storage space in the attic.
  • - High water pressure.

CONS OF SYSTEM BOILER:

  • - It can be expensive to fix and install.
  • - The ventilator is obligatory.

OPEN VENT BOILERS

Open boilers are usually connected to two tanks located in the attic of the house. One of these tanks is a small supply and expansion tank that serves to supply boilers and radiators, and the other is a larger water cooler that provides the required water for a hot water bottle.

ADVANTAGES OF OPEN VENT BOILERS:

  • - Usually used in buildings with several retail outlets (cranes, etc.) which can be used simultaneously.
  • - Relatively cheap to replace.

DISADVANTAGES OF OPEN VENT BOILERS:

  • - Low water pressure.
  • - If the boiler is empty, you may have to wait a few times before charging and warming up.
  • - It takes a lot of room compared to other boilers.

As you can see, there are advantages and disadvantages for each type of boiler if you still do not know which boiler is best for you; most boiler installations will advise you on the following list:

  • - If you have an apartment or bungalow without a ceiling – combi boiler.
  • - If your house has 2 or more bathrooms - System or open vented.
  • - If you are in the area with low water pressure - System or open vented.
  • - If you are looking for an upgrade from an existing conventional boiler to a high-efficiency boiler: System, Open Ventilation or Combi.
  • - If there are many people in your home who need hot water on request, a combi boiler or a hot water bottle system.
