What size boiler should I choose?

If you choose the wrong boiler for your home, you could end up with poor central heating and water performance for years to come. That's why CBrookes Plumbing & Heating have identified exactly how you can choose the right boiler for your property in Yate, Bradley Stoke or Thornbury.

Sizing your new boiler

Boiler size refers to the kilowatts output of the boiler (kW). Generally speaking, the more heat and hot water you need, the higher the kilowatts will be. 

In the past, older models of boilers were pre-condensing boilers, and were actually extremely inefficient, so oversizing your boiler was generally a great way to compensate for any heat loss. However, nowadays, our newer, more energy-efficient boilers mean that oversizing can actually end up costing you extra money on top of your gas bills every month! That's why we'd suggest to not over size your boiler.

Does your current boiler meet your needs?

Does your boiler meet your current needs? i.e. are you running out of hot water regularly? Does your home take too long to heat up? Is anybody moving out of your house in the near future?

And then ask yourself, would you be happy if you replaced your boiler with a direct replacement knowing what you know about the above? 

If no, then you should probably consider resizing your boiler to meet your current needs. 

Hot water demand

Most houses use combi boiler systems nowadays. 

They combine all of the old water tanks and holding tanks into one compact system that typically sits in the kitchen. They provide heat and hot water direct from the mains and they're practical and fairly low cost to run for smaller homes (with one bathroom). 

These boilers aren't however, efficient for larger homes with more than one bathroom. 

If you have a large family and/or two bathrooms, it's worth considering resizing your boiler to a larger system, likely to a conventional boiler system with hot water tanks so you always have enough hot water.

Number of radiators

How many radiators do you have in your home? 

An average 3-4 bedroom house will have around 10 radiators. And in most cases a 24-30kw combi boiler is suitable. 

Larger houses with more radiators or and en-suite bathroom generally need a boiler that powers between 30-35kw. 

If you have an even larger house with 3+ bathrooms and 15-20+ radiators, you'd be best off considering a 35-42 kw combi boiler, or changing over to a conventional system boiler. 

If your current boiler is below the recommended kw, then you should probably consider resizing your boiler.
