Types of Boilers

//Types of Boilers

Choosing a new boiler for your home, well firstly you need to choose what type of boiler you are looking to install and while making that decision you also need to consider the complete central heating system along with the type of fuel you are using for the boiler.

Best Boiler

Finding out about the best boiler for your home could be tricky and we think a bit of research could help you decide which best boiler suits for needs.

Types of Boilers

Central heating system depends on many different things such as quantity of radiators, Bathrooms and size of the house. A central heating system should be uniquely suited to your property so it’s not small which result in insufficient heating or hot water or Big which produces more than the requirements resulting in high costs.

Boiler comes in different sizes and carries different outputs. Since 2010 all new boilers must be A-rated for energy efficiency and no less than 88% efficient.

Condensing boilers

Condensing boilers are the most efficient boilers available to date. Condensing is an attribute which all gas boilers must have and it became a law in 2005.

Condensing boilers are more than 91% efficient because they extract heat from flue gases which gets lost in any non-condensing boiler.

Combi boiler

Combi boilers are also knows as combination boilers and they are very popular boilers in the UK. Most house hold currently have combi boilers installed.

A combi boiler will keep your radiators warm and will supply hot water whenever it’s needed. Combi boilers eliminate the need of cylinder or water tanks for the storage. Combi boilers are also most efficient boilers to date.

Pros of a Combi boiler

  • Combi boilers do not requires a storage tank meaning they need less space and less pipe work and gives you cleaner water.
  • Combi boilers only heat the water when required hence are energy efficient so cost effective.
  • Mains pressure is used to deliver the hot water which makes shower powerful without a separate pump.
  • Combi boilers are easy to install and less work is needed. Required less pipe work.
  • Combi boilers hardly have any pressure issues.
  • Combi boilers are most commonly used that makes it easier find a qualified engineer in case of any issue.

 

 Cons of a Combi boiler

  • Good mains pressure is required to work properly for combi boilers.
  • Using more than one hot water tap will reduced the water pressure.
  • In case of boiler break down, House will be left out without the heating and hot water.
  • Power showers don’t work with combi boilers as pressure can’t be altered.

You can read our best combi boilers 2018 article to understand more about combi boiler and decide best combi boilers for your home.

System boilers

System boilers requires a hot water storage tank and directly heats your central heating system along with producing hot water, which gets stored in the tank. System boilers are also called sealed system boilers. System boilers are compatible with solar water heating system making them environment friendly.

Pros of a System boiler

  • Doesn’t require a cold water tank so less space needed.
  • Central heating system will be more efficient as system boilers are sealed.
  • System boilers are easy to install it comes with a lot of built-in components.
  • Multiple taps could be used at once.

Cons of a system boiler

  • Hot water gets stored in the tank so in case of running out of hot water, you will have to wait for water to reheat.
  • No instant hot water
  • Needs more space for the water cylinder.
  • Complex systems and expansive to get repaired as a lot of components are built into the boiler.

Conventional boiler

Conventional boiler system is one of the oldest systems making them costly and complicated boilers. Conventional boilers are also known as regular or open vent boilers. This system consists of two tanks, one for hot water and one for cold water.

Pros of Conventional boiler

  • Mostly used in older buildings.
  • Best suited for large buildings
  • Multiple taps could be used at once without compromising the water pressure.
  • Conventional boilers are also compatible with solar thermal panels.

 Cons of Conventional boiler

  • Requires more space to fit boiler and then loft to house the storage cylinder.
  • As hot water relies on the tank so you will need to wait for boiler to heat another tank in case you run out. Storage of hot water in the tank results in loss of heat over time.
  • Restricted hot water as could only use what’s available in the tank.
  • Hard to detect leaks.

Gas boiler

Gas is considered the most common fuel in UK. More than 80% of exiting boilers used gas. Due to the legislation passed in 2005, all the gas boiler must be a condense boiler which are much more efficient. There are mainly three types of gas boilers available in the market:  Combi boiler , Regular boiler and system boiler.

Pros of Gas boiler

  • Most common and available fuel used in UK.
  • Gas is considerably cheaper then electricity.
  • Natural gas is considered environment friendly and cleanest fuel as compared to electric or oil.

Cons of gas boiler

  • Initial cost of gas boiler could be more than other type of boilers.
  • You must have gas available to your property.

Electric boiler

The principle used in electric boiler and gas boiler is same, only difference is that electric boiler uses electricity to heat the water.

Electric boilers are ideal for the properties which has no availability or restriction of gas. Electric boilers heat the water in a wet central heating system by using electricity.

Pro of electric boiler

  • Electric boilers are the most efficient boilers as they deliver 99% efficiency.
  • Need no gas to run.
  • Requires less space as much more compact then the gas boilers.
  • Contains few parts and required minor maintenance and cost efficient.

Cons of electric boiler

  • Not environment friendly as produces more waste while manufacturing.
  • In some cases cost of electricity is more than gas and is rising substantially more than gas.
  • Not suitable for heavy hot water usage.

Solid Fuel Boilers

Solid fuel boilers works in a similar way as a gas or electric boiler works. Solid fuel boilers requires solid fuel such as wood and coal. It requires the same pipes and radiators system used in other boilers however it will burn solid fuel to provide you central heating and hot water.

Pros of solid fuel boiler

  • Solid fuel boilers don’t required gas or electric.
  • Could be used with different types of fuels.
  • Solid fuel boilers could be made environment friendly by using environment friendly fuel.

Cons of Solid fuel boiler

  • You are responsible of bringing your own fuel could be time consuming.
  • Weather disruptions and fuel supply could be different at different places.
  • Solid fuel boilers could considerably cost more at the time of installation and over time due to the fuel.

Oil fired boilers

Oil fired boilers are mainly use at the properties where gas is not available directly.

These boilers used a specific type of oil which is stored at the property to provide heat or hot water.

Oil boilers has come a long way. Also available with a new Erp A-Rated energy efficiency.

Most oil fired boilers are floor standing.

Pro of Oil fired boiler

  • Fuel is considerably cheap.
  • No need of a gas supply.

Cons of oil fired boiler

  • You are responsible for your fuel and can run out any time.
  • Need extra storage for the fuel and may need to spend more to buy fuel in bulk.
