Hi Gail Worcester Bosch greenstar cdi combi boilers and system boilers are very good you can also get extended guarantees with Worcester usually 5 or 7 years for no extra cost also vailliant ecotec boilers are also very reliable for domestic properties mind you , you'll pay a minimum of £900 for the smallest kilowatt boiler and the price keeps going up but as they say you get what you pay for. Hope this is of some use to you. Regards peter
