Eastbrook Addington Aluminium — Type 20 Double Panel — Gloss White

Eastbrook Addington Aluminium Vertical Radiator 1800 x 366mm Type 20 Gloss White

A slim, flat-panel aluminium vertical radiator: 3,100 BTU (909W) at ΔT50 from a 366mm-wide footprint. Aluminium heats up fast and holds little water, so it suits modern boilers and low-temperature heat pump systems. 5 year Eastbrook warranty.

Warranty
The Eastbrook Addington Aluminium 1800 x 366mm Type 20 in Gloss White (Eastbrook code 86.0408) is a double-panel vertical designer radiator made from aluminium. It gives out 3,100 BTU (909W) at ΔT50 and 1,542 BTU (452W) at ΔT30, projects 96.5mm from the wall and weighs 16.07kg. It connects to wet central heating systems (gas, oil, LPG boilers and heat pumps) and carries a 5 year Eastbrook manufacturer warranty.
The Addington is Eastbrook’s flat-fronted aluminium radiator range. Instead of steel tubes it uses extruded aluminium sections, which conduct heat roughly four times better than steel and carry far less water — so the radiator warms the room quickly after the heating clicks on and responds fast to thermostat changes. At 1800mm tall and only 366mm wide, this Type 20 (two panels, no convector fins) is built for hallways, alcoves, bathrooms and the narrow strips of wall beside doors and windows where a horizontal panel won’t fit.

Why choose the Addington 1800 x 366mm Type 20?
1

Aluminium — fast heat-up, low water content

Aluminium transfers heat far faster than steel and the radiator holds much less water, so rooms warm up quicker and less energy is spent heating water that sits in the system.

2

Heat pump ready, with published ΔT30 output

Eastbrook publishes the low-temperature figure: 1,542 BTU (452W) at ΔT30. That is the number to use when sizing radiators for an air source heat pump.

3

Tall and narrow — 366mm wide

Puts 3,100 BTU (ΔT50) onto a strip of wall barely wider than a door frame. Ideal for hallways, landings and beside patio doors.

4

Type 20 double panel

Two flat aluminium panels, no convector fins. Clean flat front and back, with around double the output of the single-panel Type 10 of the same size.

5

Lightweight to hang

16.07kg net — light for a 1.8m radiator, which makes one-person positioning and plasterboard-friendly fixing easier.

6

5 year Eastbrook warranty

Backed by Eastbrook, one of the UK’s largest radiator suppliers, based in Gloucester.

About ΔT50 and ΔT30
ΔT50 is the European EN 442 standard rating: the radiator’s average water temperature is 50°C above room temperature (about 70°C flow with a 20°C room). Some brands quote ΔT60, which gives a higher-looking number for the same radiator, so compare outputs at the same ΔT. ΔT30 reflects a heat pump or low-temperature system running at around 50°C.

Installation notes

We recommend installation by a qualified heating engineer. Work on gas boiler systems must be carried out by a Gas Safe registered engineer.

Pipe CentresCheck the Eastbrook technical drawing before you order, or call 01282 429061
Compatible SystemsSealed and open-vented wet central heating — gas, oil and LPG boilers and heat pumps
InhibitorAluminium radiators need an aluminium-compatible central heating inhibitor. Check your inhibitor is marked safe for mixed-metal / aluminium systems
FixingHeavy-duty fixings suited to your wall type. On plasterboard, fix into studs or use rated cavity fixings
InstructionsEastbrook installation instructions are supplied in the box
Which radiator valves do I need?

Valves are not included. For a gloss white radiator, white valves give the neatest finish. Choose by where your pipes come from.

Angled White Valves

When to use: pipes come up from the floor into side connections — the most common UK set-up.

Straight White Valves

When to use: pipes rise from the floor straight into bottom connections.

Corner White Valves

When to use: pipes come out of the wall horizontally.

Frequently Asked Questions
3,100 BTU (909W) at ΔT50 and 1,542 BTU (452W) at ΔT30, per Eastbrook’s published data for model 86.0408.
Yes. Aluminium radiators heat up quickly and hold little water, which suits low-temperature systems. For heat pump sizing use the ΔT30 figure of 1,542 BTU (452W), and check the total output against your room’s heat loss.
The radiator projects 96.5mm from the wall. The radiator body itself is 63mm deep.
Type 20 means two panels and no convector fins. It gives roughly double the output of the single-panel Type 10 of the same height and width.
Yes — we sell a fluid-filled electric version with a 600W element that needs no pipework, just a fused spur.
Yes. Use a central heating inhibitor that is approved for aluminium and mixed-metal systems. Some older inhibitors are not aluminium-safe.
No. Valves are sold separately — see the Valves tab for matching white angled, straight and corner options.
The radiator carries a 5 year Eastbrook manufacturer warranty against manufacturing defects.
