Product Description
The T7Design 3.5kW Lightweight Heater with Side Vents provides compact, high output cabin heating and windscreen defrosting in space restricted installations. It achieves this using a 3.5kW copper and brass heater core with high flow tube design, high fin density and ultra-thin wall construction, combined with a lightweight single speed axial fan and configurable outlet positions.The following features explain how this heater delivers effective heat output and flexible installation options:3.5kW Copper & Brass Heater Core: A specially engineered copper and brass matrix with high flow tube layout, high fin density and ultra-thin wall tubes maximises thermal transfer from the coolant circuit into the airflow, enabling you to generate strong heat output from a compact unit and maintain clear visibility and cabin warmth in demanding conditions.High Flow Core Design: The internal coolant passages are designed to promote efficient coolant circulation across the full surface area of the core, allowing you to extract consistent heat energy from the engine cooling system and achieve stable, reliable heating performance during continuous use.Ultra-Thin Wall Tube Construction: The thin wall tube structure increases the effective heat exchange surface area without increasing overall size, enabling you to install the heater in tight spaces while still achieving effective defrosting and interior heating.Single Speed Axial Fan Assembly: The lightweight axial fan draws air directly through the heater matrix and expels it through the outlet nozzles, reducing electrical load by using approximately 25% of the power of traditional centrifugal blowers and keeping overall system weight at least 50% lower for efficient operation.Dual Adjustable Lower Side Vents: Two integrated lower vents can be manually adjusted to direct heated air into the footwells, allowing you to target lower cabin areas and improve comfort during cold weather driving.Configurable Upper Outlet Positions: Up to three outlet positions are available in the upper section of the enclosure, with outlet spigots supplied loose for you to rivet in place where required, giving you control over duct routing and airflow direction within your installation layout.Multiple Outlet Diameter Options (32mm 51mm): Four outlet diameters ranging from 32mm (1.25") to 51mm (2") allow you to match the heater to your chosen ducting size, ensuring proper airflow distribution and straightforward integration into your existing ventilation system. (See note below)Lightweight Compact Motorsport-Focused Design: The low mass construction combined with a compact enclosure and 3.5kW high efficiency heater core allows you to install effective cabin heating and windscreen defrosting in vehicles where packaging space and weight distribution are tightly controlled, making it suitable for competition cars, kit cars, custom builds and heater upgrades in classic vehicles while maintaining practical integration within confined interiors.You gain a compact 3.5kW heating solution that supports reliable windscreen demisting and controlled cabin airflow through adjustable and configurable outlets. The lightweight axial fan and efficient heater core design help you manage electrical load and available space within your vehicle. Adding this heater to your setup provides a practical and well-engineered solution for maintaining visibility and cabin comfort in a wide range of installations.Please note: The ducted outlets on this unit are available in a range of sizes and configurations. You can choose from 32mm / 38mm / 45mm / 51mm or a blanking plate for any of the 3 outlet ports. Once you have placed your order a member of our team will contact you for your choice of outlets. Outlets are supplied loose and require riveting to the heater body.
