Why Choose Alpha Combi Boilers?
With rising energy costs and increased focus on efficiency, choosing the right combi boiler has never been more important. Alpha's domestic combi range provides heating solutions for small, medium, and large homes, all designed to deliver maximum energy efficiency while maintaining the highest standards of reliability.
More importantly, Alpha combines decades of industry expertise with cutting-edge innovation, which explains why their boilers consistently receive excellent customer reviews. The company manufactures a comprehensive range of boilers, including system, regular, and combi models, all running on natural gas with exceptional energy efficiency ratings.
Understanding Combi Boilers
A combination, or 'combi,' boiler is a compact system that delivers both central heating and hot water from a single, efficient unit.
Unlike traditional boiler systems, combis deliver instant hot water whenever you need it, eliminating the need for a separate cylinder or storage tank. This makes them particularly suitable for homes in London, where space is often at a premium.
When you turn on the heating, the boiler shifts into heating mode, sending hot water through the radiators to warm your home. This ability to provide both heating and hot water from one compact unit is exactly why combi boilers have become such a popular choice for homeowners across London.

Key Combi Boiler Considerations
The combi boiler's size is measured in kilowatts (kW), which indicates its power. A higher kW rating means the boiler can deliver more heating and hot water output. Choosing the correct output ensures your boiler can adequately heat your home and provide sufficient hot water for your household's needs.
Efficiency RatingsModern Alpha combi boilers achieve excellent efficiency ratings, meaning less energy is wasted and more money stays in your pocket. High-efficiency boilers convert more fuel into useful heat. It reduces both your carbon footprint and energy bills.
Flow RateThe flow rate measures how many litres of hot water your boiler can deliver per minute and how fast it reaches your taps and showers. A higher flow rate is especially important in homes with several bathrooms or where hot water is used heavily, ensuring everyone gets a steady and reliable supply when they need it.
