The Grant Vortex Eco External Wall Hung System 16-21kW Oil Boiler is a high-efficiency oil-fired boiler designed for domestic heating purposes. It is part of the Grant Vortex range, known for its energy-efficient and eco-friendly solutions.

Key Features:

• Wall-Hung Design: This boiler is specifically designed to be mounted on a wall, making it ideal for homes or buildings where floor space is limited. It is often used in outdoor or external installations, helping save internal space.
• Output: The 16-21kW range indicates the boiler's heat output capacity. This makes it suitable for small to medium-sized homes, depending on the specific heating and hot water needs.
• Eco-Friendly & High Efficiency: The Vortex Eco model is designed to meet modern energy efficiency standards. It uses condensing technology, which captures and reuses heat from flue gases, improving overall efficiency and reducing fuel consumption. It is SEDBUK A-rated, meaning it meets the highest efficiency standards for oil boilers, which results in lower running costs and a smaller environmental footprint.
• External Installation: Being an external model, it is built for installation outside the home. This is convenient for properties that may not have space indoors or for those that want to reduce noise levels inside the house. However, it requires protection from the elements, often with a protective casing.
• System Boiler: The Vortex Eco External System model is a system boiler, meaning it works with an pressurized unvented hot water cylinder to provide both central heating and hot water. It’s often used in systems where a pressurized hot water system is required.
• Ideal for Rural or Off-Gas Properties: As it runs on oil, the Vortex Eco is particularly beneficial for homes located in rural or off-gas areas where natural gas is not available.

• Durability: It features a robust design, including a stainless steel heat exchanger and weather-resistant casing, ensuring longevity and performance even in challenging outdoor conditions.

Advanced Features:

• Burner technology: The Grant Vortex Eco features a stainless steel heat exchanger and a high-efficiency Riello burner for maximum efficiency and reliability.

• Noise reduction: It operates quietly, making it suitable for installations where noise might be a concern.

• Built-in frost protection: The boiler is equipped with features that protect it from freezing in cold temperatures.

In summary, the Grant Vortex Eco External Wall Hung System Oil Boiler is a high-efficiency, wall-mounted oil boiler that is perfect for homeowners who require reliable heating and hot water but have limited space or prefer an external installation. It's a good choice for off-gas homes looking to reduce energy consumption and environmental impact.
