If your boiler has broken and is beyond repair, then it is the perfect opportunity to replace it with a more efficient system. Nothing lasts forever, so do not mourn the demise of your boiler; instead, look at it as an opportunity to replace dated technology with something new and shiny, whichever boiler you choose, it is likely to be a considerable upgrade. Your boiler is an integral part of your property’s infrastructure. It is responsible for providing hot water and fuelling your central heating system. Thus, when your boiler ceases to function, it can be an extremely stressful and worrying situation.

If you are going to invest your hard-earned money into a new boiler, you need to be certain that the system you choose is suitable for your specific requirements. We want you to make an informed decision, before choosing a boiler; do your research. This article will discuss the different types of boilers available, including their advantages and disadvantages. It should help you to determine which type of system is suitable for your budget and lifestyle. However, if you would prefer an expert opinion, you can schedule a free consultation with one of our knowledgeable Ipswich Plumbers.

Conventional Boilers

Regular Boilers (otherwise known as Conventional Boilers) are best suited to properties that have a traditional central heating system. This type of boiler uses both a hot and cold water storage tank, which are often installed in your loft. Once the boiler is ignited, either by gas or oil, the water passes through into the hot water tank, ready to be used. When the thermostat is switched on, the hot water is circulated throughout the property’s central heating system. The supply of hot water is also directed through your taps and shower heads when in use.


  • With a Conventional Boiler, you do not need to worry about using two fixtures at the same time; the water flow is consistent, regardless of how many taps or showers are in concurrent use.
  • For older properties that feature a traditional central heating system, it is a lot easier to have a Conventional Boiler installed.
  • You can heat up a large volume of water at a time with a Conventional Boiler, you should always have enough.


  • Due to their two tank design, a Conventional Boiler has a larger footprint than other types of boiler, making them less suitable for installation in smaller properties. Also, as the system is bigger, it may take our Plumbers in Ipswich longer to install.
  • They do not heat up water on demand. It holds a finite amount of hot water, if you use up your entire supply – then you will need to use the Hot Water Advance feature to heat up additional water.
  • These systems require a lot of pipework, you may have problems in the colder months with your pipework freezing. Your loft is likely to be ones of the coldest places in your property.

Combination Boilers

An increasingly popular choice is the Combination Boiler or ‘Combi-Boiler’ for short. It is a much newer type of boiler featuring up to date technology. The most notable difference between a Combi-Boiler and a Conventional Boiler, is that a Combi does not store hot water, rather it heats the water directly from the mains when you use a fixture in your property. As a result, you do not need a hot water storage cylinder or a cold water storage tank. Thus, a Combination Boiler is a suitable option for smaller properties due to its smaller footprint.


  • A Combination Boiler is often able to deliver higher pressure as it is supplied directly from the mains.
  • With a Combi, you do not need storage tanks. This will take up less space than a Conventional Boiler, making it the ideal option for smaller properties or ones which do not have a loft to accommodate storage tanks.
  • You will always have hot water – Combi-Boilers provide instant hot water, on demand. So, you can ditch the cold showers!


  • A Combi-Boiler is not always suitable for larger properties. As they do not use a storage tank and the water is heated up on the fly, if several appliances attempt to use water at once, the flow will be shared amongst them. This will often cause the water pressure to drop significantly.
  • The Combi-Boiler may not be compatible with older pipework. If this is the case, you would need to consider a full central heating system installation. This would obviously be more costly option than a boiler replacement alone.

System Boilers

If you have a larger property and would like to achieve the functionality of a Combination Boiler without the drawbacks, then a System Boiler is likely to be the most ideal solution for you. It is the perfect balance between a Combination and Conventional Boiler. Just like a Combi, the majority of the heating is undertaken within the boiler itself. However, like a Conventional Boiler, it requires a cylinder to store hot water. This type of boiler is able to provide a constant supply of hot water, so you will never be without.


  • You can have a constant supply of hot water to a large number of outlets at the same time, this is not possible with a Combination Boiler. This makes a System Boiler the ideal choice for properties with more than one bathroom.
  • System Boilers are compatible with Solar Water Heating Systems. This is an eco-friendly option which can save you money!
  • Unlike a Conventional Boiler, you would not need a loft tank. So, you will have the benefits of a Combi without the footprint of a Conventional Boiler.


  • Although a System Boiler is less invasive than a Conventional Boiler, it does still require a hot water cylinder, so it will take up more space than a Combi-Boiler.
  • Your cylinder will need to be adequately insulated to ensure that the hot water is able to stay hot whilst inside the cylinder.

Condensing Boilers

In order to understand how a Condensing Boiler works, you should first understand the way in which other types of boilers create hot water. Your standard boiler will use gas or oil to heat the water. These chemical reactions leave by products such as steam and carbon dioxide. In non-condensing boilers, the by products are usually released and go to waste. Whereas, with a Condensing Boiler, the waste gasses are passed into an additional heat exchange to create extra heat. In the United Kingdom, it is a regulatory requirements that all boilers must have some condensing functionality.


  • Condenser Boilers are extremely efficient, by using the waste gasses, you will get the most out of your money.
  • You would not need a water tank, so a Condensing Boiler is a suitable option for smaller properties.
  • They are extremely safe. The boiler is fully sealed by design to ensure safety.


  • The process required to install a Condensing Boiler may be more extensive than for other boiler types. Due to the steam produced by the waste pipe, it will need to be fitted in a more specific location for safety reasons. Also, it will require a fluid drainage system, this is because the process of condensation produces acidic waste.
  • In order to allow the gases to move within the boiler, a fan may be required which adds to the complexity of the system.

Boiler Installations in Ipswich

When you purchase a new boiler, you need to ensure that it is suitable for your property. Almost every boiler on the market will be energy efficient. Due to the regulations stating that every boiler has to be able to condense the excess gasses to some extent, you will generate additional heat which would have otherwise been lost. Once you have determined which type of boiler is suitable for your property and requirements, you can begin to look at specific models. You can check the energy efficient of a specific boiler on the Building Energy Performance Assessment database. You will find two types of rating: SAP Winter Efficiency and SAP Hot Water Efficiency. Even though there may not be much difference in efficiency between modern boilers, it is always worth checking your chosen models specification.
