An Overview of Worcester Bosch
The brand Worcester Bosch is a UK-origin brand and has been operating since 1962. It was founded as Worcester Engineering Co Ltd and began operations by producing oil-fired central heating equipment. Later, it widened the line by including gas-fired boilers on the list. In 1996, the company was acquired by the Bosch Group, which further made the company more reputable due to quality and innovation.
The brand scores in customer satisfaction surveys and has Which? Best Buy status several times, all of which are clear proofs of how reliable and performant Worcester Bosch boilers are.
Product Range Overview
Worcester Bosch offers a wide array of boilers for meeting different household requirements and satisfactions. In general, there are three types of boiler supplied by the brand:
Combi Boilers: The most popular type of boiler in the UK, especially for small houses. Combi boilers provide both heating and hot water on demand without the need to use a separate water tank.
System Boilers: For larger houses with more than one bathroom, these boilers work with a separate hot water cylinder and do not require a cold water tank. They give out a constant supply of hot water to two or more taps at a time.
Regular Boilers (Heat-only): These are traditional boilers that will require a hot water cylinder and a cold water storage cistern. They are ideally suited for older homes with traditional systems.
