SPC has launched the Belgravia Tilevector Duo Plus, a ceiling-mounted fan convector designed specifically for use with heat pumps and low temperature hot water (LTHW) systems. The Duo Plus joins the existing Tilevector range as the largest and most capable unit for low temperature applications, delivering up to 7.8kW at 50/40°C flow and return water temperatures.
Standard Fan Convectors and Low Temperature Hot Water Systems
Standard fan convectors are designed for optimum performance at traditional boiler flow temperatures, typically 80/70°C, and work extremely well in those applications. However, heat pumps and modern condensing boilers operate most efficiently at lower flow temperatures, usually in the range of 45-55°C. At these temperatures, a standard fan convector is simply working outside its intended design conditions.
That’s where the Tilevector Plus range comes in. Rather than replacing like for like, the Plus units have been specifically developed with an enhanced heat exchanger and increased casing depth, 260mm compared to 210mm on standard Tilevector units, to optimise performance at low water temperatures. The result is a ceiling fan convector that complements heat pump and LTHW system design, delivering the output those systems need without compromise.
Tilevector Duo Plus: Key Details
The Duo Plus is a double-tile ceiling unit measuring 1195mm x 595mm x 260mm, suitable for installation into standard 600mm T-bar suspended ceiling grids as well as plasterboard ceilings. Units can also be suspended from solid ceilings.
The unit weighs 35kg and connects via 15mm copper flow and return. EC motors are fitted as standard for energy efficiency, and the full range of Belgravia accessories and controls is compatible, including the SPC Modulo proportional controller.
The full Belgravia Tilevector Plus range
The launch of the Duo Plus completes a four-strong Tilevector lineup:
- Tilevector Solo – single-tile unit (595mm x 595mm x 210mm) for standard hot water systems
- Tilevector Duo – double-tile unit (1195mm x 595mm x 210mm) for standard hot water systems
- Tilevector Solo Plus – single-tile unit (595mm x 595mm x 260mm) for heat pump and LTHW systems
- Tilevector Duo Plus – double-tile unit (1195mm x 595mm x 260mm) for heat pump and LTHW systems
The Solo Plus delivers up to 3.5kW at 50/40°C, making it the right choice for smaller spaces or where a single ceiling tile position is available. Where greater output or larger room coverage is needed, the Duo Plus steps up with more than double the capacity.
Looking for wall or floor-mounted LTHW fan convectors?
The Tilevector Plus range is part of SPC’s wider Belgravia fan convector family, which includes the Belgravia Supreme and Belgravia Classic – wall-mounted units also available with enhanced coils for heat pump and low temperature hot water systems.
Whether you need ceiling-mounted, wall-mounted, or floor-level units, SPC’s Belgravia range offers a compatible solution for LTHW projects across commercial, education, and healthcare sectors.
Frequently Asked Questions
The Plus variants have a deeper casing (260mm vs 210mm) and an enhanced heat exchanger with greater surface area. They are engineered to deliver effective heating output at the lower flow temperatures produced by heat pumps and condensing boilers, typically 45-55°C. Standard Tilevectors are rated at 80/70°C.
Performance data is published for the most commonly specified flow and return temperature combinations – 50/40°C, 45/35°C, and 50/35°C – which reflect the industry standard operating conditions for heat pump and LTHW systems. If your project requires data at different operating conditions, get in touch with the SPC team at spc@spc-hvac.co.uk and we can help.
