The Grant Vortex Eco Internal Wall Hung 16-21kW Open Vent Oil Boiler is a type of oil-fired central heating boiler designed for residential heating applications. It is part of Grant’s Vortex range, which is known for providing high efficiency and reliability.

Here’s a breakdown of its key features:

• Wall-Hung Design: This boiler is compact and designed to be mounted on the wall, which saves floor space and makes it ideal for homes with limited space.
• Output Range: It has an output of 16-21kW, which is suitable for small to medium sized homes with a typical demand for hot water and heating.
• Open Vent: The boiler uses an open vent (or conventional) system, which typically involves a separate feed and expansion tank, commonly installed in an attic or loft space. This system can be a good choice for homes that are replacing an older, traditional boiler and heating system.
• Eco-Friendly: The Vortex Eco range is designed with energy efficiency in mind. It features advanced technologies like Grant’s Vortex stainless steel heat exchanger, which ensures high-efficiency operation while reducing fuel consumption. The boiler meets modern environmental standards, contributing to lower carbon emissions compared to older models.
• Oil-Fired Heating: This model runs on heating oil, making it suitable for properties not connected to the gas grid. The oil-fired nature provides a reliable heating source for homes in rural or remote areas.
• Grant Vortex Range: The Grant Vortex boilers are well-regarded for their reliability, efficiency, and ease of maintenance. They are a popular choice in the UK and other regions where heating oil is commonly used.
• Ease of Installation: The wall-hung format simplifies installation, and Grant boilers typically come with easy-to-understand instructions and features that make setup smoother for heating engineers.

If you are considering this boiler, it’s typically suited for homes looking to upgrade their oil heating system to a more efficient model or those who need a reliable heating source in areas without natural gas availability.
