Are external oil boilers good? | Boilerhut

At Boilerhut, we understand the demands of larger homes with multiple bathrooms. This is why we recommend an oil system boiler for consistent, powerful central heating and an abundant supply of hot water when off-grid.

Designed to work in harmony with a hot water cylinder, our oil system boilers are ideal for installation in kitchens or utility rooms, ensuring your home enjoys fully pressurised hot water at all times.

The top-of-the-line LCB700 Blue Flame oil system boiler, available in both internal and external models, experiences unmatched reliability and performance.
