When adding radiators or fitting more powerful ones, check the capacity of the boiler.
If the boiler’s modern, you probably won’t have a problem, but ask a heating engineer if in any doubt.

A new boiler is a big investment and you’ll want to be sure it’s money well-spent. Not only do the boilers made by Worcester Bosch Group (www.worcester-bosch.co.uk) have a great reputation, they also currently have a fantastic five-year guarantee, so you know they’re a good investment.
If your household uses lots of hot water, Worcester’s A-rated Greenstar i System Compact boilers (usually bought through your installer), teamed with Worcester Greenstore mains-pressure unvented cylinders (for storing hot water) are an unbeatable combination. With these cylinders, multiple bathrooms can be supplied simultaneously - if you’re having a bath, it fills in no time and won’t change if someone runs a tap or a shower.
The cylinders, which are guaranteed for an impressive 25 years, are really well insulated and come in different sizes to suit different households. There’s no water tank taking up space in the loft and you’re never likely to run out of hot water, so it’s similar to having a combi boiler... only much better.
To get the best out of the high-efficiency boiler and cylinder, use the DT20RF Digital RF thermostat. This clever piece of kit lets you set three separate time periods for both your central heating and hot water each day. You can even choose your target room temperature, so you’re always comfortable.
The DT20RF also has a holiday function to suspend your normal heating and hot water times when you’re away and then resume them when you get back, ideal now we’re coming into holiday season.
