The Grant Euroflame Outdoor Condensing Oil Boiler is a free standing external unit designed for heating systems where internal space is limited. It operates on kerosene and uses condensing technology to recover latent heat from flue gases, improving overall efficiency and reducing fuel consumption.
This model offers an adjustable output range between 26kW and 36kW, making it suitable for larger heating loads. It incorporates a stainless steel heat exchanger and a Riello RDB burner for clean combustion. The boiler achieves an A-rating on the SEDBUK and HARP databases and complies with OFTEC and EC directives for performance and emissions.
The unit is designed for connection to a multi-directional flue system, with options for side or rear exit when using the appropriate Grant flue kit. It features a weatherproof casing and factory fitted frost protection for outdoor installation. Flexible pipe entry points allow easier integration, and its design enables straightforward servicing with accessible components.

- Stainless steel heat exchanger for improved efficiency
- Riello RDB2.2 burner ensures clean combustion
- SEAI HARP efficiency rating of 92.1%
