How do I choose the right wattage or heat output for my room?

Match wattage to room size and insulation: smaller rooms often need 700–1000W, medium rooms 1500W, and larger spaces 2000W or more; the range on offer includes 700W, 1000W, 1500W and 2000W models and BTU groupings up to 6000–6999. If you have a compact bathroom, a 750W towel-style unit such as the Towelrads Metz 429 x 610mm 750W will normally suffice. For an open-plan living area choose a 1500–2000W panel like the TCP or K-Rad Capri 2000W options to ensure consistent warmth. Also check whether the model is single, double or triple panel, because more panels increase heat output without changing wattage.

What's the difference between single, double and triple panel heaters, and which should I pick?

Single panels are shallow with one convector fin and suit small rooms or where you need a low projection, while double and triple panels add parallel faces and extra fins to increase heat output for medium to large rooms. a single-panel 1000W model is ideal for a small bedroom, whereas a triple-panel configuration is better if you need higher output but have limited wall width. Triples project further into the room, so they give stronger convection but take more space. Pick the configuration that balances required heat with how much the unit can protrude from your wall.

Which material and profile should I choose for bathrooms and kitchens?

Aluminium and steel panels deliver fast, efficient convection and are lightweight, while ceramic options retain heat a little longer and give a slightly steadier output; glass panels are sleek and often come with smart controls. For a damp bathroom choose steel or specially rated ceramic units and place them away from direct splashes; a glass WiFi panel can work but check IP or suitability for wet zones. Flat profiles sit close to the wall for a minimal look, while curved profiles project a little and circulate air differently, curved suits a more sculpted style, flat is discreet behind fixtures.

Can these electric panel heaters be fitted without rewiring, and do smart WiFi options require specialist wiring?

Most panel heaters are electric and can either be hardwired or come with a plug-in option depending on the model, so many are suitable for straightforward retrofits without new wiring. Smart WiFi models such as the TCP Smart glass panels and the Dimplex PLXE are electrically powered but generally plug in or are hardwired depending on your chosen variant; they do not need extra data cabling, only a WiFi connection. If you plan a permanently concealed connection choose the hardwired version and have a qualified electrician complete the final connection.

Should I buy a vertical or horizontal panel, and what about towel radiator options?

Vertical panels are ideal where horizontal wall space is limited, tall options such as the K-Rad Capri 1600 x 544mm (2000W) suit narrow walls or hallways, while horizontal units work well under windows or along long walls. If you want to warm towels, look at the Towelrads Metz range (429 x 610mm 750W up to 429 x 1035mm 2000W) which combines drying function with room heating. Think about how the heater will integrate with other fixtures: vertical saves sill space, horizontal fits below windows and keeps heat spreading evenly across lower wall area.

Panel Heaters

Panel heaters work using a convection heating cycle. This essentially means that cool air is drawn into the heater, warmed to temperature, and released back into the room. Warm air pushes the cool air down which is then drawn back through the bottom of the heater, continuing the cycle until a constant temperature has been achieved. Panel heaters are electric so will require either wiring in or plugging in and are an ideal solution to quickly heating a room.
