Calora is a smart electric aluminium radiator that you can run from your phone or smart speaker, with no plumbing needed. Anthracite grey is the designer's neutral: darker and more considered than white, softer than black, and it sits well with wood floors and grey or white walls.
Choose from 3 sizes from 1000W to 2000W. Control it from the LCD display, a phone app, Google Home or Alexa, and set a 7-day, 24-hour programme. Open window detection turns the heat down when it senses a sudden drop in temperature, and overheat protection is built in. A low surface temperature mode (40–55°C) keeps it safer to touch, with a Heat Plus mode (70–80°C) for faster warm-up.

Help choosing
Size a radiator by heat output (BTU), not by how it looks on the wall.
Enter your room size to see the heat output you need.
- Match the output to the room. Use the BTU figure from the calculator. In a bathroom, a towel rail alone often heats a small room; bigger rooms may need a radiator too.
- Check your connections. Measure the gap between your pipes and choose valves to suit: angled, straight or corner (see the valve helper on our valve pages).
- Heat pump? At the lower water temperatures heat pumps run at, expect roughly half the listed output.
- Summer use. Central heating rails only warm up when the heating is on. A dual fuel kit adds an electric element where the rail supports it.
