What size boiler do I need for a large 5 bed house?
On average, a 5 bed house will require a boiler with an output of approximately 30 kW, nevertheless, it is worth mentioning that size does not necessarily mean physical size.
To determine the boiler size you need for a large 5-bedroom house, it is important to note that boiler size is measured in kilowatts (kW), which indicates the amount of heat the boiler can produce per hour.
The majority of UK homes use outputs of between 24 and 42 kilowatts. A useful method to determine what size boiler your home needs is to take into account every radiator in your house. Therefore, if every radiator accounts for 1.5 kW or 2 kW, for example, a home with 10 radiators would need a boiler with an output of around 20 kW.
| Boiler size needed overview | ||
|---|---|---|
| House size | Number of radiators | Boiler size (kW) |
| 3 bedrooms | 10 | 20 |
| 4 bedrooms | 12 | 24 |
| 5 bedrooms | 15 | 30 |
In the table above we have provided a table showing the number of radiators and the corresponding boiler size needed. For more information, you can also view our guide on the best boiler for a 3 bedroom house. However, it is important to note that this is just a general guide.
The actual size of the boiler you need will depend on multiple factors, including the size of your home, the type of insulation you have, and the climate you live in. It is always best to consult with a qualified heating engineer to get a tailored professional assessment.

Which boiler types are the best for a large 5 bedroom house?
Thebest boiler for a 5 bedroom house will also be determined by the type of boiler you choose. There are three types of boilers: combi boilers, system boilers and conventional boilers (also known as regular boilers).
For example, combination boilers are the most popular type of boiler in the UK thanks to their efficiency and compact design. They can heat water for your central heating and hot running water without the need for other components, becoming an excellent option for those looking to save up some extra space.
On the other hand, system boilers employ an extra amount of help from a hot water storage cylinder. This cylinder can store a large supply of hot water and keep it warm enough for distribution throughout the house.
This allows them to provide a sufficient amount of hot running water and central heating for properties that are too big to handle for combi boilers.
In the event of needing enough hot water to supply a 5 bedroom house with multiple bathrooms and radiators, a system boiler is the best fit for you. That is unless you already have a conventional boiler installed. These boilers are the oldest type of boiler and used to be the norm in the past.
Nowadays, there has been a shift away from conventional boilers due to technological advances and the large amount of space they require due to the extra components they require. They not only need a cylinder to provide hot running water to a property but also a cold water storage tank to act as their water supply.
Therefore, the only reason to get a new conventional boiler is to replace an old one, since this will reduce installation costs as there is no need to alter the pipework.
However, a new combi or system boiler will free up a lot of space. Therefore, the boiler you choose will ultimately depend on the size of your house and how much space you are willing to give up for installing your new boiler or replacing your old one.
With this being said, it is perfectly understandable that taking into account all of the factors that will affect your final decision on choosing the best boiler for a 5 bedroom house might become quite overwhelming.
To make your life easier, we have put together the best lists for combi, system and conventional boilers for a large 5 bed house. Of course, the final decision will be yours to make according to your specific needs and circumstances.
Top 3 best combi boilers for a large 5 bed house
Generally, thebest boiler for a 5 bedroom housewill be a boiler that has enough capacity to provide heating and running hot water for multiple bathrooms simultaneously.
Combi boilers heat water instantly when you need it, drawing directly from the mains water supply. This means they don’t store hot water in a tank, which can limit their ability to provide heating and hot water simultaneously, especially when there’s high demand from multiple bathrooms.
For this reason, the most logical choice would be to opt for thebest system boiler for a large houseor a conventional boiler, since they store hot water in a cylinder providing extra capacity.
However, there are combi boilers that are powerful enough to become suitable for a 5 bedroom house with two or more bathrooms.
Therefore, the best combi boiler for a large house can also be an interesting option for your 5 bedroom house. To help you narrow down your choices, we have compiled a list of our top 3best combi boilers for large houses:

Worcester Bosch Greenstar 8000 Life 35
