The BENEFITS of Boiler Installation & Replacements
What boiler type do you need?
In the UK, there are three main types of boilers commonly installed into domestic properties and businesses. These are combi boilers, system boilers and conventional boilers.
MPE Plumbing Heating Gas, offer the supply and installation of all these three boiler types as below.
What is a Combi Boiler?
Combi boilers are space-saving that house all of the water & heating components in one compact unit.
- Heating directly from the mains water, a combi boiler provides an unlimited supply of instant hot water when you turn on a shower or tap.
- Water is delivered at mains pressure when it arrives at your showers and taps.
- A combi boiler only heats water when a hot shower or tap is turned on, which ensures maximum efficiency and won’t cost you anything until used.
- For quick delivery of hot water the length of the pipe run from the boiler to the furthest outlet must be considered.
- Combi boilers deliver hot water through your taps or showers at mains pressure which means if your mains water pressure is good, you can enjoy showers without needing any extra pumps.
- The radiator heating portion of a combi boiler is a pressurised closed loop system heated by the boiler as required.
If you are short on space and are looking to better utilise areas of your home, a combi boiler is ideal because there is no need for a hot water cylinder in an airing cupboard or cold water tank in the loft. As hot water is not stored in an external cylinder but is instead delivered instantaneously when required.
Combi boilers are designed to minimise the energy that is used to heat the water and means there is no need to heat up and store water, thereby reducing your carbon footprint and cutting down your energy bills.
Combi boilers are economical to run, straightforward to install and are typically installed in a kitchen, utility or airing cupboards.

What is a System Boiler?
System boilers are ideal boiler solutions for homes with high hot water demand. System boilers are also known as sealed system boilers sit in the middle between a combi and conventional boilers because they can easily serve pressurised unvented hot water cylinders and do not require exterior pumps or header tanks.
- A system boiler works on a closed loop heating system, and can serve a mains pressure unvented hot water cylinder for storing hot water.
- System boilers are ideally suited for large homes with a higher number of radiators and bathrooms.
- System boilers require a separate cylinder for storing hot water, it is important to consider whether you have enough space to accommodate both. It is space considerations that prevent many dwellings from being able to accommodate a hot water storage cylinder and system boiler.
- If you have an airing cupboard or large cupboard space to accommodate a hot water cylinder, then a system boiler can be suitable for installation.
Consider a system boiler as opposed to a combi boiler if you require hot water from more than one outlet at a time and higher levels of hot water flow than a combi boiler can provide.
Typically, combi boilers can only supply hot water to one shower or tap at a time.
System boilers can accommodate multiple showers and taps calling for hot water at the same time, this makes them ideal for homes with multiple bathrooms.
You might consider a system boiler as opposed to a conventional boiler because of the lack of space in the loft for the header tanks which feed the hot water cylinder and maintain the water level in the radiator system.
Another reason for considering a system boiler over a conventional boiler would be if your home suffers from low static water pressure from the heating header tank to older radiators that suffer from poor water circulation.
What is a Conventional Boiler?
A conventional boiler system requires a boiler + hot water storage cylinder + cold water storage tank. Conventional boilers are suited to larger properties due to them requiring a hot water storage cylinder usually housed in an airing cupboard, and a cold water storage tank usually installed in the loft.
In open vented boiler systems, there will also be a feed and expansion tank to service the radiator central heating system
Conventional boilers are open vented boiler systems. In an open vented boiler system, the system utilises a feed and expansion tank to supply the central heating circuit with water and accommodate the expansion of water when it is heated by the boiler. The feed and expansion tank is usually situated in the loft, where it forms the highest point of the central heating system and feeds into the boiler using gravity. It is for this reason that the cold water tank is installed in the loft as high as possible to increase the water pressure. It is also the reason it is sometimes called a header tank.
An open vented boiler system is connected to a feed & expansion tank in the loft which is filled with cold water from the mains supply.
Whilst most feed & expansion tanks are made from plastic today, in the past, they were often made from asbestos and galvanised steel.

What is a Back Boiler?
Whilst old and inefficient, back boilers can still be found in homes across the UK. MPE Plumbing Heating Gas specialise in back boiler replacement to a more efficient condensing boiler such as a combi boiler.
- Back boilers are conventional boilers that were designed to be installed into the recess of an open fireplace hearth and hidden behind a gas fire.
- A back boiler system has a back boiler unit (BBU), plus a separate cold water tank and hot water cylinder installed elsewhere in your home, to provide heating and hot water.
- The cold water tanks will usually be found in the loft, whilst the hot water cylinder will usually be found in an airing cupboard.
First installed into homes in the 1960s and up to 2005, back boilers were seen to be a great choice due to their compact dimensions and ability to be hidden away.
However, changes to UK building regulations in 2005 meant that new boilers installed into UK properties need to be condensing, and as the majority of back boilers are not condensing, the installation of them stopped.
Whilst back boilers haven’t been installed into properties for 16 years, there are still many of these in homes across the UK.

Heating Boiler Service
Regular boiler maintenance is important in order to ensure the appliance is not only burning safely and efficiently but also to avoid more serious problems.
- A boiler service typically takes approximately 45 minutes and varies depending on the type of boiler.
- Our Gas Safe registered engineers can service your boiler according to the UK Gas Safety standards.
5 Tips Prevent a Boiler Breakdown & Repair
1) Annual boiler service: Without an annual boiler service, there’s a good chance your boiler won’t last as long and could break down.
2) Run boiler periodically in the summer: Turning a boiler off for long periods can cause parts to seize up and not start in the winter.
3 ) Prevent frozen pipes in winter: Run your heating at a low temperature whilst you are out and insulate pipes, especially your external condensate pipe.
4) Bleed radiators: Releasing trapped air ensures your radiators are heating efficiently and puts less strain on your boiler.
5) Powerflush or MagnaCleanse: To remove heating system sludge, remedy noisy boilers, pumps, cold radiators and extend the life of your boiler.
