Rounded LTHW fan convectors for commercial and public buildings
Belgravia Supreme Fan Convectors are LTHW heaters with a rounded casing and no sharp corners. EC fans with three speeds blow warm air from a hot water coil into the room. The range comes in four sizes, all 735 mm high, in vertical, horizontal and inverted casing styles, with outputs up to 16.3 kW.
Manufactured in Leicester by S & P Coil Products Limited, Belgravia Supreme Fan Convectors have been supplied to thousands of schools across the UK, and are also specified for nurseries, healthcare buildings, libraries, churches, offices and other commercial and public buildings where appearance and safety both matter. Enhanced and lowflow coils suit heat pump systems, and the Belgravia Supreme Plus adds fresh air ventilation.

What are Belgravia Supreme Fan Convectors?
Belgravia Supreme Fan Convectors are fan-assisted heaters for LTHW (low temperature hot water) systems. A fan draws room air in through the inlet grille, across a coil heat exchanger made by SPC fed with hot water, and blows warm air back into the room through the outlet grille. Fan speed and the hot water flow can both be controlled, so the Belgravia Supreme responds quickly when a room needs heat.
The Belgravia Supreme has an ergonomically rounded casing with no sharp corners, for busy rooms where people move close to the heating. It comes in white (RAL 9010) or two tone grey, and can be painted in a special finish to order. For a casing with square, clean lines, see Belgravia Classic Fan Convectors, and for the whole range, see Belgravia Fan Convectors.

What sizes do Belgravia Supreme Fan Convectors come in?
Belgravia Supreme Fan Convectors come in four lengths, all 735 mm high and 235 mm deep. An extended casing, which houses on/off valves inside the unit, is available on the three smaller sizes and shares its length with the next size up.
| Model | Case length (mm) | Extended case length (mm) | Maximum weight (kg) |
|---|---|---|---|
| SPR40 | 800 | 1000 | 31 |
| SPR60 | 1000 | 1300 | 41 |
| SPR90 | 1300 | 1600 | 46 |
| SPR150 | 1600 | Not available | 52 |

How much heat does a Belgravia Supreme Fan Convector give?
At 80/70°C water and 18°C air, Belgravia Supreme outputs at high fan speed range from 5.7 kW (SPR40) to 16.3 kW (SPR150).
- Three fan speeds (high, medium and low), set by thermostat, switch or BMS
- EC fans with a specific fan power as low as 0.12 W/l/s at low speed
- Noise from NR32 at low speed, with the room conditions stated in the brochure
Can fan convectors work with heat pumps?
Yes. Belgravia Supreme Fan Convectors can be fitted with an enhanced or lowflow coil for water temperatures below 60°C.
- Enhanced coil: more surface area for low water temperatures at standard flow rates
- Lowflow coil: for low flow rates and wide temperature differences, with ½” connections
- An SPR150 with the enhanced coil gives 6.8 kW at 45/35°C, high speed, 18°C air
Can a Belgravia Supreme have a low surface temperature?
Yes. With the Active LST option, available on the A and BS styles, Belgravia Supreme Fan Convectors keep the hottest part of the casing at or below 43°C.
- A sensor monitors the outlet grille, the hottest point on the casing
- An independent valve modulates the water flow to hold the set temperature
- Factory fitted, with no extra pipework or wiring: see Active LST Fan Convectors
Full performance data for every size, speed and water temperature is in the Fan Convector Brochure.
Belgravia Supreme casing styles, fresh air, controls and options
Belgravia Supreme Fan Convectors come in three vertical styles (A, BS and HS) and two horizontal styles (QS and VS), all 735 mm high. Most styles are also available with reversed air flow, and the BS style with an inverted casing for high-level wall mounting.
Vertical
Low-level floor or wall mounting.
Horizontal
Ceiling mounted.
Inverted
High-level wall mounting.
Fresh air
Belgravia Supreme Plus: heating and ventilation in one unit.
The Belgravia Supreme Plus adds a fresh air inlet spigot and motorised damper to the Belgravia Supreme, so one unit provides both space heating and ventilation.
- When outside air is let in, the damper closes the room inlet grille, and the outside air passes through the heat exchanger before entering the room. This prevents draughts and offsets the ventilation load at source
- The damper is controlled separately from the heater, normally opened by a BMS signal (by others) from a CO2 or occupancy sensor
- Plus A, Plus B and Plus C styles, 775 mm high, for wall or floor mounting, with the fresh air spigot in the back plate
- In summer, units can provide free air movement when the boiler or heat pump is off
- The extended casing is not available on the Belgravia Supreme Plus
Dimensions and performance are in the Belgravia Supreme Plus Data Sheet.
Belgravia Supreme Fan Convectors can be controlled locally, from a room thermostat or from a building management system.
- Built-in on/off or change speed thermostats (T1, T2; not available on reversed air flow units)
- Remote and tamper-proof thermostats (RT1, RT2, TRT1, TRT2)
- SPC Modulo proportional touch controller and the SPC Vision digital controller
- Rocker switches for on/off, summer/winter and fan speed
- BMS relay for remote enable/disable (BMS1) and on/off plus fan speed via 0-10V (BMS2)
- Low water temperature fan cut-outs (LTC, ALTC) for boiler systems; these are not suitable for weather-compensated heat pump systems
Belgravia Supreme Fan Convectors can be built with the accessories a project needs. Check the brochure’s accessories table for the full list.
- Extended casing to house on/off valves inside the unit (SPR40, SPR60, SPR90)
- 2-port on/off valves for waterside control
- Air filter covering the inlet grille
- Plinths and wall mounted stiffeners
- Lockable or tamper-proof access panels
- Fuse spur box and customer connection box
- Two tone grey casing (RAL 9002 and RAL 7044), black grilles, or special paint finishes in RAL colours

Frequently Asked Questions
Yes, in practice. LTHW (low temperature hot water) and LPHW (low pressure hot water) are both used in the UK to describe the hot water heating circuits that fan convectors run on. Belgravia Supreme Fan Convectors work on these systems, from traditional boiler flow temperatures of around 80°C down to heat pump temperatures when fitted with an enhanced or lowflow coil.
Below 60°C flow, choose the enhanced coil, which has more surface area to keep useful outputs at standard flow rates. If the system also runs at low flow rates with a wide temperature difference between flow and return, choose the lowflow coil, which uses ½” connections. Our team can select the coil for your water temperatures.
Both come in four sizes with outputs up to 16.3 kW, use the same coil options and are built in Leicester by SPC. The Belgravia Supreme has a rounded casing with no sharp corners, one 735 mm height and a fresh air version, the Belgravia Supreme Plus. The Belgravia Classic has a rectangular casing in more heights, including recessed and 2000 mm tall units. Choose the casing that suits the room and how it is used.
Yes. The Belgravia Supreme Plus has a fresh air inlet spigot in its back plate and a motorised damper, so one unit heats the room and brings in outside air, warmed by the coil on the way in. The damper is usually opened by the BMS when a CO2 or occupancy sensor calls for fresh air. Ventilation design for the building is by others.
Yes. The rounded casing has no sharp corners, and the Active LST option on the A and BS styles keeps the casing at or below 43°C, the NHS guideline threshold. Tamper-proof access panels and thermostats are available for busy public rooms. Read our guide: Specifying Fan Convectors for Schools: What to Choose for a Half-Term or Holiday Window
Yes. The BS style is available with an inverted casing for high-level wall mounting, which keeps floor space clear. An inverted BS unit heats the Pine Room at Ystradgynlais Library.
Yes. The standard finish is white casing and grilles (RAL 9010). A two tone grey casing is also available, with the top, bottom and grilles in RAL 9002 and the front and sides in RAL 7044, or with black grilles. Special paint finishes are available to order: send us the RAL colour with your enquiry.
Two BMS options are available. BMS1 is a relay for a remote enable/disable signal, and BMS2 gives on/off and fan speed control from a 0-10V signal. Units can also be controlled by local thermostats, switches or the SPC Modulo and SPC Vision controllers.
Yes. Belgravia Supreme Fan Convector BIM objects are available from SPC on bimstore. Dimensions for every style are also in the Belgravia Supreme IOM in the downloads below.
