At City Plumbing, we stock a massive inventory of 1000x600 radiators, the undisputed baseline specification for UK living rooms and master bedrooms. Because a 600mm high by 1000mm wide panel is the most frequently installed radiator in the country, specifying this exact size guarantees immediate stock availability across all major brands. Free delivery on orders over £75 ensure you can secure these essential high-volume panels.

The Standard Under-Window Specification
- The thermal curtain effect: Standard UK casement windows are typically 1200mm wide. Placing a 1000mm wide radiator directly beneath them creates a near edge-to-edge "thermal curtain" of rising heat. This optimally counteracts the cold downdraught from the glazing before it can enter the room.
- Sill clearance: The 600mm height is explicitly engineered to drop perfectly beneath a standard 800mm-high window sill. This leaves the mandatory 100mm clearance at the bottom for cold air to enter the convector fins, and 100mm at the top for the warm air to escape, ensuring the convection cycle works at peak efficiency.
- The BTU sweet spot: A 1000x600 panel strikes the perfect balance between physical footprint and heat output. When specified as a double panel (Type 22), this exact size reliably produces between 4,000 and 5,000 British Thermal Units (BTUs), perfectly matching the heat loss of an average-sized UK living space without dominating the wall.
Frequently Asked Questions (FAQs)
If I upgrade a 1000x600 Type 11 to a Type 22, will my existing pipes line up?
While the 1000mm width remains identical (meaning your left-to-right pipe centres will not change), a Type 22 double panel is significantly thicker than a single panel. This means the valve inlets will sit further away from the skirting board. To complete the upgrade, you will either need to slightly pull and adjust the copper tails emerging from the floor, or specify offset radiator valves and parts to bridge the new depth without straining the rigid pipework.
Can a 1000x600 double panel radiator be hung on a standard stud wall?
Yes, but it requires correct specification. A fully filled 1000x600 Type 22 radiator holds approximately 6 to 7 litres of water and can weigh upwards of 35kg in total. You cannot rely on standard plastic wall plugs in plasterboard to hold this cantilever weight. You must either anchor the mounting brackets directly into the vertical timber studs or use heavy-duty plasterboard fixings engineered specifically for heavy, dynamic loads.
How much central heating inhibitor does a 1000x600 panel require?
Standard liquid dosing for central heating inhibitor (such as Fernox or Sentinel) is one 500ml bottle per 100 litres of system water, which typically covers up to 10 standard radiators. Because a single 1000x600 Type 22 panel only holds roughly 6 litres of water, it only accounts for a fraction of your system's total volume. Whenever you drain down to fit a new 1000x600 panel, you must re-dose the entire system circuit, not just the individual radiator.
