How many radiators can a 24kw boiler run?

If you are stuck between choosing that one perfect boiler that fits your home with the right size than here you go with some of the basic information you would require to figure out the best. To begin you first need to know what type of boiler would suit your needs and the demand of time.

What type of boilers are you looking for?

In our opinion, you initially need to be clear on what type of boiler would suit you more in order to discover the best choice for you.

Combination Boilers- These come up in the most compact sizes to suit smaller houses where the requirement of hot water is comparatively less.

System boilers- They are proven to be ideal for homes with more than one bathroom, in order to constantly supply hot water to multiple numbers of tap.

Regular boilers- The regular or conventional ones are found to be perfect for the homes where there is a constant need of hot water.

Now that you know the way each type of boiler would serve you, let’s move on to the next important and considerable point.

The size of the boiler you are looking for is also known as the output that gets measured in kilowatts. It is believed that higher the kilowatt, more powerful the boiler would be.  Domestic boiler systems usually range between 24kW to 42kW in size. Now here you need to find a boiler that is just right; a boiler that is too small will not be able to heat your home adequately or produce enough hot water. A boiler that is too big will use more fuel, making your energy bills more expensive and your carbon emissions unnecessarily high.

You might be wondering as to how many radiators can your boiler run.

Well a boiler with an output rating of 24kW can run up to 10 radiators.  

What size boiler do i need for my house?

Boilers come being available in 3 series of sizes ranging from 24-27kW, 28-34kW and 35-45kW.

  • On a rough estimate, the 24kW-27kW range of boilers are made to suit the houses and apartments that are comparatively smaller, with up to 10 average size radiators and 1 bathroom.
  • The 28-34kW range of boilers is designed and manufactured to be suitable for the medium large size houses and apartments that have up to 15 average size radiators with1 normal size and 1 ensuite bathroom.
  • Whereas, for the large houses that are made to have up to 20 average size radiators and 2 bathrooms, a 35-45kW boiler would be installed.

To conclude the above mentioned points, it can be stated that properties with higher demand of hot water would require a boiler with higher kW, which means “the higher the output of the unit, the better the flow rate of hot water would be”.
