Bryant 33NM3Domestic Hot Water Air-To-Water Heat Pump
16.8 EER
4.9 COP
48 dB
Bryant's dedicated air-to-water heat pump for domestic hot water generation. Ultra-efficient, ultra-quiet hot water for Portland homes.
How the Bryant 33NM3 Transforms Water Heating
High-Efficiency Hot Water
The 33NM3 generates domestic hot water using heat pump technology instead of electric resistance or gas. With a 4.9 COP, it produces nearly 5 units of heat for every 1 unit of electricity consumed.
Up to 75% reduction in water heating costs compared to standard electric water heaters.
Year-Round Performance
Using ambient air as a heat source, the 33NM3 works efficiently even in Portland's cooler months. The variable-speed rotary compressor adjusts output based on hot water demand.
Reliable hot water production in Portland's mild climate with consistent efficiency.
Dedicated Water Heating
Unlike hybrid heat pump water heaters, the 33NM3 is a dedicated air-to-water heat pump designed specifically for hot water generation with commercial-grade components.
Purpose-built for hot water with higher capacity and longer lifespan than residential hybrids.
Ultra-Quiet Operation
At just 48 dB, the 33NM3 is whisper-quiet - important since water heaters often run during quiet nighttime hours when other equipment is off.
Won't disturb sleep or conversations even when installed near living spaces.

Frequently Asked Questions
How does the 33NM3 differ from a standard heat pump water heater?
The 33NM3 is a dedicated air-to-water heat pump designed specifically for hot water generation. Unlike hybrid water heaters that combine heat pump with electric resistance backup, this is a commercial-grade unit with higher capacity, longer lifespan, and 4.9 COP efficiency.
What does 4.9 COP mean for my energy bills?
COP (Coefficient of Performance) of 4.9 means the unit produces nearly 5 units of heat energy for every 1 unit of electricity consumed. That's about 490% efficiency compared to 100% for standard electric resistance water heaters - potentially reducing water heating costs by up to 75%.
Will it work efficiently in Portland's climate?
Yes! The 33NM3 extracts heat from ambient air and performs well in Portland's mild climate. The variable-speed rotary compressor adjusts to temperature changes, maintaining efficient hot water production year-round. It's ideal for Pacific Northwest conditions.
How quiet is the 33NM3?
At just 48 dB, the 33NM3 is whisper-quiet - comparable to a refrigerator running. This is important since water heaters often operate during quiet nighttime hours. It won't disturb sleep even when installed near living spaces.
What warranty is included?
The Bryant 33NM3 includes a 10-Year Parts Limited Warranty when installed by a Factory Authorized Dealer and registered within 90 days. This covers the variable-speed compressor, coils, and all functional components.
