Price Comparison
Rheem starts from $3,200 installed (before rebates), while Chromagen starts from $2,800. That is a difference of roughly $400 at the entry level. Chromagen is the more budget-friendly option upfront, though Rheem may deliver savings through lower running costs over time. Both prices are for fully installed systems before government rebates and STCs, which can reduce the out-of-pocket cost by $1,000 to $3,000 depending on your state.
Efficiency Comparison
COP (Coefficient of Performance) is the key efficiency metric for heat pumps. A higher COP means more heat output per unit of electricity consumed. Rheem achieves a COP of 3.5, while Chromagen reaches 3.5. Both systems offer identical efficiency, so running costs will be very similar.
Warranty Comparison
Rheem offers a 5-year tank warranty and 5-year compressor warranty. Chromagen offers a 5-year tank warranty and 5-year compressor warranty. Both brands offer the same tank warranty length, so warranty coverage is comparable.
Noise Comparison
Noise is an important consideration, especially for suburban installations where the unit may be close to bedrooms or neighbouring properties. Rheem operates at 47dB, while Chromagen runs at 48dB. The Rheem is quieter at 47dB. At this level, you may want to consider placement carefully to avoid disturbing bedrooms or neighbours.
Climate Suitability
The type of refrigerant a heat pump uses significantly affects its performance in cold weather. Rheem uses R134a refrigerant, while Chromagen uses R134a. Both units use the same refrigerant type, so cold-weather performance should be comparable. R134a performs well in moderate climates but may lose some efficiency in very cold conditions.
