| Cleaning regime | Wiped down with the floor during the standard mop round. No tools or covers off, and no need to close the corridor. | Full strip-down weekly per AHCP guidelines. Deep-clean team, specialist tools, and the ward or corridor out of service while it happens. | Rarely cleaned in practice. Access needs a ladder or out-of-hours booking. |
| Infection control | Fully sealed aluminium surface. No internal cavity for C. difficile, MRSA or biofilm to incubate in. | Cover cavity collects dust, lint and biological matter. Convection currents then distribute it into the room. | Minimal dust accumulation on the face, but no active hygiene benefit. |
| Anti-ligature | No exposed pipework, valves, brackets or fixings anywhere on the visible profile. Naturally anti-ligature. | Covers can be leveraged off; valves, tails and mounting brackets remain exposed underneath. | Inherently out of reach at ceiling level. |
| Anti-tamper | Top cap needs a tool to remove. Through-bolted corner joints with pick-resistant mastic for secure MH and custodial settings. | Covers are engineered to come off for servicing. That is a known vulnerability in secure environments. | Ceiling-mounted, so out of reach for tampering but also out of reach for routine repair. |
| Surface temperature | HBN 27 compliant LST option. Front face stays below 43°C even at full output. | LST while the cover is on. 65–75°C radiator surface exposed the moment the cover is removed. | Radiant face typically 80–120°C but out of contact distance. |
| User comfort | Even radiant warmth all the way around the room. No hot head, no dead-leg from heated floors, and no cold corners. | Localised hot-wall heat with a stuffy zone above the radiator and cold corners further into the room. | Heat projected downward onto the occupant. Known to distress users with learning difficulties, dementia or sensory sensitivity. |
| Response time | 10–15 min to comfort from a cold start on a gas-boiler circuit. Shuts off in under 10 min. | 10–15 min from cold, but 20–30% of the rated output is trapped inside the cover and never reaches the room. | 5–10 min to feel warm, but the room has almost no thermal memory. Heat drops away fast once the panel switches off. |
| Retrofit impact | Replaces the existing skirting. 1–2 rooms per day, no floor lifting, no pipework re-routing, single trade. | Drop-in swap onto existing radiator tails, but each cover needs bespoke joinery to fit the wall. | Requires ceiling void, local structural strengthening, and re-routing of lights, fire alarms and detection around the panel. |
| Heat-pump ready | Works at 35–45°C flow. Retains ~48% of rated output at dT20. | Loses ~70% of rated output at 45°C flow. Usually needs major oversizing for heat-pump compatibility. | Electric only. No flow-temperature story, so not a heat-pump emitter. |
