Why Aluminium for Central Heating?
Three practical reasons aluminium outperforms steel for modern heating systems.
Heat pump readyLow temp ✔
Aluminium delivers excellent heat output at lower flow temperatures — well suited to air-source and ground-source heat-pump systems.
Fast responseSmart controls ✔
Aluminium heats up quickly and responds rapidly to thermostats, timers and smart heating controls, so no energy is wasted.
Corrosion resistantBuilt to last
Aluminium naturally forms a protective oxide layer, helping it withstand warm, humid conditions. Install in a clean, correctly treated central-heating system for optimum life.

Heat Output by Size & System
Calculated to EN 442. ΔT60 = high-temp boilers (80°C flow). ΔT50 = standard gas boiler (75/65°C). ΔT30 = heat pump (50/40°C). All at 600mm height.

Heat pump owners: use the ΔT30 column. Aluminium retains a strong proportion of its rated output at lower flow temperatures.

Frequently Asked Questions
Q.
Is the Reina Resia Horizontal compatible with a heat pump?
A. Yes. The Resia Horizontal is aluminium, which delivers excellent heat output at the low water temperatures (40-50 degrees C) used by heat pumps. Use the Delta T30 column in our heat output table for accurate figures.
Q.
What valves do I need for the Resia Horizontal?
A. The Resia has standard 1/2 inch BSP connections. We recommend thermostatic radiator valves (TRVs) for individual room control. A valve set adds 90mm total to the pipe centre measurement.
Q.
What are the pipe centres on the Resia Horizontal?
A. Pipe centres equal the radiator width, from 470mm to 1420mm. For pipe centre measurement including valves, add 90mm.
Q.
Which size Resia Horizontal do I need?
A. Use the room fit calculator on this page. Enter your room dimensions and heating system type - the calculator shows whether the radiator will meet your heat loss. As a guide, allow around 100 BTU per cubic metre for a modern well-insulated UK room.
Q.
What finishes is the Resia Horizontal available in?
A. White and Anthracite, across all six widths (470mm to 1420mm). Both finishes share the same aluminium construction and heat output.
Q.
Why choose an aluminium radiator for central heating?
A. Aluminium heats up 5 to 10 times faster than steel or cast iron, responds quickly to thermostat changes, and works efficiently at the lower flow temperatures that heat pumps and modern condensing boilers use.
