Determining Your Boiler Requirements: Output and Size
Three key factors determine the right boiler size for your 3-bedroom home: the number of bathrooms and radiators, your hot water usage, and your property's insulation quality.
For a typical 3-bedroom house, you'll need a combi boiler with an output between 29-35kW. This range guarantees you'll have enough power to run up to 15 radiators and handle simultaneous hot water demands – like when someone's taking a shower while the dishwasher's running.
If you're considering a system or regular boiler instead, you can opt for a lower output of 18-26kW since these models work with a separate hot water cylinder. For these setups, a 210-litre cylinder usually does the trick for a family home with two bathrooms.
To calculate more precisely, count your radiators and multiply by 2kW. Then add 3kW for hot water if you're getting a combi boiler.
Don't forget to factor in about 10% extra capacity for those chilly winter mornings.

Cost, Efficiency and Smart Features Worth Considering
Making sense of boiler costs, efficiency ratings, and smart features doesn't have to give you a headache.
For a 3-bedroom house, you're looking at £500-£2,500 for the boiler itself, plus £500-£1,500 for installation.
Modern boilers are quite the brainy bunch, with efficiency ratings between 80-95%.
Whether you need a combi or system boiler will depend on your home's specific heating requirements.
If you're going for a new gas boiler, it'll need to be at least 92% efficient – that's like getting 92p worth of heat for every pound you spend on fuel.
Smart features are where things get interesting.
You can control your heating from your phone (perfect for those "did I leave the heating on?" moments), and some systems are clever enough to adjust themselves based on the weather outside.
Want to save even more?
Look for models with modulating burners that adjust their output like a car's cruise control.
And if fitting your boiler into a kitchen cupboard is important, many modern units are designed with space-saving in mind.
