A compact room deserves proper heating — not a radiator taking up half the wall

The Mini Room Kit is built for the rooms where space is everything — box rooms, cloakrooms, utility areas. ThermaSkirt replaces both the skirting board and the radiator in a single component, giving you the wall back and the warmth you need.

Boiler Output

540W

1,780 BTU — from 4.5 metres of skirting

Heat Pump Output

250W

890 BTU — at low flow temperatures (35–45°C)

Why it works

Everything a small room needs. Nothing it doesn't.

Your wall space, returned

Removing the radiator gives you 600–900mm of wall back — enough for a shelving unit, a cot, or simply the breathing room a small space needs. Furniture goes wherever you want it.

Warm in minutes, not hours

Aluminium construction and low water volume mean ThermaSkirt reaches temperature in 20–30 minutes. Responsive enough to heat on demand — switch on, feel the difference, switch off when you're done.

Silent by design

No expansion clicks, no ticking, no gurgling. Critical in a box bedroom or nursery. ThermaSkirt runs without making a sound — day or night.

Safer for families

Low surface temperature without additional covers. No sharp edges, no hot panels to fall against. RoSPA data shows 86–87% of radiator injuries are impact injuries — ThermaSkirt eliminates that risk entirely.

What's in the box

Everything you need — nothing you don't

Arrives as two packages: the skirting lengths and a components kit with every fitting, bracket and seal included.
