What is the energy efficiency of these models?

Energy use is driven more by how the unit is used and installed than by the model name alone.

Solid-door undercounter fridges (R200SN/R200SVN) generally have an efficiency advantage in bars because the door is opened for short grabs and then closed, with less cold-air loss than glass display doors.

Glass-door bottle coolers (BC20) trade higher visibility for higher load: internal lighting, frequent browsing, and warm bar air hitting the door area can increase consumption.

To keep running costs down in Irish bar conditions:

Keep clear ventilation space around the condenser area and avoid boxing units in.

Set temperatures realistically for your serve style, and avoid “colder than needed” setpoints.

Don’t overload air paths. Leave space for airflow around stock.

Clean dust from the condenser area routinely; a dirty condenser is one of the most common causes of rising energy use.

If you’re comparing two specific listings, use the official energy label or spec sheet for like-for-like kWh figures, because it accounts for the test method used for that exact model.
