After sales support

Choose a brand that has maintained a good reputation for after services and repairs because product warranty is an important & considerable factor. Most of the boiler breakdowns are a result of poor installations so make sure you get the boiler installed by the company itself because in case of getting a boiler from a reliable brand, installed by someone else, the manufacturers may cost you repair if they determine a fault in installation.
