What Is an External Module Oil Boiler?
An external module oil boiler is designed to be installed outside the home rather than in a kitchen, utility room or boiler house. This makes it ideal for properties where indoor space is limited, where noise reduction inside the home is preferred, or where an outdoor replacement boiler is the most practical installation option.
The Grant Euroflame HE 50-90 external module provides central heating through a conventional oil-fired boiler system. It is suitable for use with compatible heating controls, hot water cylinders and system components, depending on the overall heating design.
Flue and Installation Flexibility
This model is supplied with a factory-fitted multi-directional flue arrangement and supports optional side or rear flue exits. This helps installers adapt the flue route to suit property layout and site conditions, subject to the boiler installation manual and current oil boiler regulations.
Multiple flueing options and pipe entry choices make this outdoor module suitable for a wide range of replacement and new installation scenarios.
Why Choose the Grant Euroflame HE 50-90 External Module?
The Grant Euroflame HE External 50-90 combines efficient condensing performance with a practical outdoor casing. It is a strong option where a homeowner wants to free up internal space while retaining the performance of a high-efficiency Grant oil boiler.
Its stainless steel heat exchanger design, Riello burner, A energy rating and external weather-resistant format make it suitable for professional oil boiler installations where durability, serviceability and flexible siting are important.
