Alpha Heating Innovation is a well-established UK-based company known for its heating products, including boilers. Alpha was part of the Immergas Group, one of Europe's leading manufacturers of domestic and commercial boilers. Alpha offers a variety of boilers to suit different needs, which generally fall into three categories:

1. Combi Boilers: Alpha's combi boilers are popular for their efficiency and compact size. They deliver hot water directly from the boiler whenever a hot water tap is turned on, eliminating the need for a separate hot water cylinder.
2. System Boilers: Alpha's system boilers require a cylinder for storing hot water, but the major heating and hot water system components are built into the boiler itself, making them easier to install than regular boilers.
3. Regular Boilers: Also known as heat-only or conventional boilers, these boilers are suitable for homes that have a traditional heating and hot water system linked to a separate hot water cylinder.

In addition to boilers, Alpha offers a range of other products, including gas water heaters, solar thermal systems, and air source heat pumps. Alpha is known for focusing on simplicity, quality, and reliability in its product designs. They also offer comprehensive warranty packages, with certain boilers coming with warranties up to 13 years. The company is also dedicated to offering strong after-sales support. This includes providing access to trained service engineers, and a dedicated technical helpline to assist with any questions or concerns that customers may have.
