Frequently Asked Questions
Does the 230mm depth of the Oxford 570mm radiator interfere with curtains when installed under a window?
Yes, this is a common oversight. The 230mm depth means the front of the radiator sits roughly 260mm-270mm from the wall (including the air gap). If you have floor-length curtains, they will drape over the radiator, trapping heat and potentially damaging the fabric. You typically need to use sill-length curtains or blinds, or ensure your curtain rail projects at least 300mm from the wall to clear the front of this deep radiator.
How does the 570mm height compare to the 470mm model in terms of heat output efficiency?
The 570mm model provides approximately 20% more heat output per section (392 BTU vs 326 BTU) than the 470mm model. Because it is taller, it creates a slightly stronger natural convection current (chimney effect), pulling cold air from the floor and throwing warm air higher into the room, making it technically superior for rooms with higher ceilings (2.4m+) compared to the lower version.
Can I use standard 15mm valves for a large Oxford 570mm radiator (e.g., 20 sections)?
A 20-section Oxford 570mm radiator produces nearly 8,000 BTUs. While standard 15mm valves can technically handle the flow, they may introduce resistance. For radiators of this size and volume, we often recommend using 3/4 inch valves with reducers, or ensuring your 15mm pipework has a good flow rate (balanced correctly) to ensure the radiator fills and heats evenly from end to end without lagging.
Is the Oxford 570mm suitable for use with a ground source heat pump (GSHP)?
Yes, it is an excellent choice. The 230mm depth gives it a massive surface area relative to its footprint. Even at the lower flow temperatures of a GSHP (Delta T 30
What wall stay length is required for the Oxford 570mm given its 230mm depth?
You cannot use standard 160mm wall stays. The rear column of the Oxford 570mm sits roughly 150-160mm away from the wall (depending on skirting). You must order Extended Luxury Wall Stays (typically 250mm or longer) that can be cut down to size. The stay should be clamped between the sections near the top to prevent the 100kg+ unit from tipping forward.
Does the 570mm height fit under a standard modern window sill?
Standard modern window sills are often 800mm-900mm from the floor. The 570mm radiator leaves a generous clearance of 200mm-300mm. This is technically ideal for convection, as it allows plenty of space for the hot air to rise and circulate without getting trapped under the sill, maximizing the efficiency of the radiator.
What is the water content of the Oxford 570mm radiator compared to a panel radiator?
The Oxford 570mm holds roughly 2.5 to 3 litres of water per section. A 10-section model holds ~25-30 litres. A comparable steel panel radiator might hold only 5-8 litres. This high water content means the Oxford takes longer to heat up (high thermal inertia) but continues to radiate heat for 45-60 minutes after the boiler stops, smoothing out temperature fluctuations in the house.
