What is the difference between hydronic and electric plinth heaters, and which is better for your room?

Hydronic plinth heaters circulate hot water from your central heating and are ideal if you want to use existing radiators or underfloor heating, offering steady background warmth; nine hydronic models are shown here. Electric plinth heaters run independently and suit rooms away from the central system, such as a utility or garage, and there are six electric models available. If you have a regularly heated kitchen the hydronic option usually works best for continuous heat, while an electric model is handy for occasional use or where plumbing isn't convenient.

How do I know if a plinth heater will fit under my cabinets?

Check the unit height against your kickboard space, most models sit in the 76–100 mm height range, with a few at 51–75 mm and 101–125 mm. Widths commonly run from about 450 mm up to 650 mm, and depths vary from roughly 249 mm to 355 mm, so measure your available recess before ordering. if your kickspace is 100 mm high and 500 mm wide, a 76–100 mm high and 500–549 mm wide model will fit neatly.

What heat output do you need for your kitchen or utility?

Outputs on these plinth heaters range from about 1.0 kW up to 3.0 kW, with many models between 1.0–1.5 kW and 1.6–2.0 kW. Small cloakrooms or laundry cupboards will often be comfortable with around 1.0–1.5 kW, while a typical kitchen or larger utility may need 1.6–2.6 kW; open-plan or larger areas benefit from the higher 2.6–3.0 kW units. Match the output to the room size and insulation, a compact utility with average insulation would be fine with a 1.5 kW plinth heater.

Which grille finish will suit your décor and where are the finishes available?

You can choose from white, brushed steel and stainless steel grilles across the range, so pick one that either blends in or creates a subtle feature. White grilles work well under white shaker cabinets to stay discreet, while stainless or brushed steel suits contemporary kitchens and pairs nicely with stainless appliances. Several Smith's models list brushed or stainless steel grilles, and Myson units also come with matching grilles for a cohesive look.

What controls and accessories can help you get the most from a plinth heater?

Most models are sold with manual control, and there's a wall-mounted control switch available for Smith's SS3/5/7/9 if you prefer convenient temperature adjustment. Accessories include flexible hoses for hydronic connections, spare grilles in different finishes, and a fan convector variant (SS5/12V) if you want faster air movement and quicker warm-up. If you want simple steady heat, stick with the manual models; add the wall switch or fan convector when you need quicker or easier control.
