Step 1

How to measure correctly.

A perfect fit depends on three measurements: width, height, depth.

Width

Measure between the outermost points of your radiator — including valves, supply pipes and brackets. Add at least 3 cm clearance on each side so the cover can be removed easily.

Height

From the floor to the top of the radiator. The slat arms run above the radiator, so measure to its highest point, including bleed valves.

Depth

From the wall (pipe entry) to the front edge of the radiator. Add 2–3 cm for air circulation.

Pro tip

Send us a photo of your radiator with a tape measure — we'll check your numbers for free and reply within 24 hours.

Step 2

Oak vs. MDF vs. Metal.

Three materials, three worlds. Here's why solid oak is the only choice that doesn't end up in a skip after three years.

Step 3

Understanding heat output & convection.

The biggest fear with radiator covers: "Will my room get colder?" Our answer: not with ours.

How a radiator really heats

A radiator emits about 70 % of its heat through convection (warm air rising) and 30 % through radiation. Block convection with a closed MDF box and the radiator loses massive output.

Why our design works

Our open slat construction has 30–40 % free air flow area. Warm air rises unobstructed; cold air enters at the base. Result: up to 96 % of original output.

Step 4

15-minute installation.

No tradesman needed: rail on the wall, cover on the rail, done.

Unpack

Open packaging. Take piece out carefully and let it acclimatise in the room for 24 hours.

Fit the rail

Hold the wall part of the hanging rail level, mark the holes, drill (6 mm), plug and screw it tight.

Hang it

Lift the cover and set it onto the rail from above. The rail sets the position – level it once and everything sits straight.

Done

That's it. Take a photo, let your guests ask "where did you get that?"

The hanging rail is always included. Screws and wall plugs can be added in the configurator as a fixing kit (€32) – or use your own to suit your wall. You'll need a 6 mm drill bit either way. To read the heat meter or to clean, simply lift the cover off.

Step 5

Care & cleaning.

Solid oak is low-maintenance — but a little care doesn't hurt.

Everyday cleaning

Dust with a soft cloth or hoover with a brush attachment. For marks: a slightly damp cloth is enough.

Re-oil every 1–2 years

Oiled and natural variants benefit from re-oiling with linseed or hard-wax oil. A bottle of our care oil is available for €12.

For scratches

Light scratches sand out with grit 240+ paper, then re-oil. Deeper scratches: let us know, we'll send a free repair kit.
