The right boiler, built for your home
Choosing a new boiler can feel daunting — especially with so many types, sizes, and brands on the market. Whether you’re replacing an old unit or installing one in a new property, picking the right system will affect your comfort, energy bills, and reliability for years to come.
At Gosai Heating & Gas, we help London homeowners find the perfect boiler that balances efficiency, performance, and cost.
The three main types of boilers
-
Combi boilers: Compact and efficient, ideal for smaller homes and flats. They provide hot water on demand and don’t require a storage tank.
-
System boilers: Great for larger families. They store hot water in a cylinder, ensuring multiple taps can run at once.
-
Conventional boilers: Perfect for older properties with traditional heating systems. They require both a cylinder and a tank but can handle high water usage.
