Install requirements in District of Columbia

Electrical

Dedicated 240V, 30A circuit (most models). Some newer 120V plug-in models exist but most residential units require 240V. Check the unit's nameplate for exact requirements.

Condensate drain

Heat pump water heaters produce condensate during operation. A condensate drain line to an approved location (floor drain, condensate pump, or exterior) is required.

Air space

Approximately 700 cubic feet of surrounding air (roughly a 10x10x7-foot room). The heat pump extracts heat from surrounding air. Insufficient air volume reduces efficiency and can cause the unit to underperform. Some manufacturers allow ducting to supplement air supply in smaller spaces.

Noise

Heat pump water heaters produce operational noise similar to a window AC unit (45-55 dB). Consider placement away from bedrooms.
