The horizontal D37 was laid out for cabinets that are wide but shallow, where a vertical cylinder would push into the drain trap area. Its 310 × 240 × 240 mm body mounts flat against the back wall, so the tank sits behind the basket zone and the sink trap keeps its full clearance. Plumbing runs sideways: the standard top-face ports can be rotated to a left-hand or right-hand exit at the factory to match the existing pipe stubs.
Because a horizontal tank has a larger wetted surface, the D37 uses an extra layer of PU foam around the shell to hold 6 L of water at temperature with a standby loss below 0.9 kWh/24 h in the 30 °C lab cycle. The 1500 W element is positioned along the lower quadrant to keep the outlet stream hot even when the cabinet is cold in winter; a thermal fuse plus a high-limit thermostat back up the main control.
Facility managers who retrofit older offices like the horizontal profile because it can be installed between studs or above a dropped ceiling in a utility chase. Wulinfeng supplies a ceiling/floor dual-use bracket for the D37H, and the flat rear face allows the unit to be screwed directly to plywood without additional standoffs, cutting installation time to about twenty minutes per point of use.
