Choosing the Right Boiler for Your Property
Combi Boilers
Highly efficient and space-saving. No separate tank needed, providing hot water on demand with high pressure. Perfect for smaller homes.
System Boilers
Requires a hot water cylinder but no loft tank. Built-in components allow for quicker installation and consistent water flow to multiple taps.
Regular Boilers
Traditional ‘heat only’ boilers using both a tank and cylinder. Best for large households where hot water is needed from multiple taps simultaneously.
Electric vs. Gas Boilers
Prices are inclusive of all taxes.
