Hotel refurbishment buyers frequently ask for a heater that can be wall-mounted inside a tiled bathroom cabinet with zero floor contact. The D37 vertical body achieves that with a rear hanging plate, keeping the 240 × 240 × 310 mm casing 25 mm off the floor so cleaning crews can mop underneath. Because the inlet and outlet both sit on the top face in the standard configuration, the plumbing loop stays inside the cabinet and the visible area below the basin stays free of hoses.
Guest-room demand cycles are short and frequent, so the D37's 1500 W element is matched to a 6 L tank that refills to temperature in roughly a quarter of an hour. The control fascia offers a mechanical dial for basic properties or a digital panel with a blue backlight for a higher perceived tier; both variants keep the same chassis, so a property can mix the two across floors without changing cabinet cutouts.
OEM buyers ordering the D37 for villa projects or serviced apartments can request a 2.4 m cord with an EU schuko plug, a left- or right-handed outlet layout, and custom packaging with installation templates printed in the buyer's language. The unit is also available with a 304-grade inlet filter and a flow limiter that caps draw at 3 L/min for guest-room conservation programs.
