Price Comparison
Stiebel Eltron starts from $3,500 installed (before rebates), while Midea starts from $2,500. That is a difference of roughly $1,000 at the entry level. Midea is the more budget-friendly option upfront, though Stiebel Eltron 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. Stiebel Eltron achieves a COP of 3.8, while Midea reaches 3.4. The Stiebel Eltron is 12% more efficient, which translates to roughly $0 less per year in running costs. Over a 10-year lifespan, that efficiency advantage adds up to approximately $0 in savings.
Warranty Comparison
Stiebel Eltron offers a 5-year tank warranty and 5-year compressor warranty. Midea 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. Stiebel Eltron operates at 44dB, while Midea runs at 50dB. The Stiebel Eltron is quieter at 44dB. At this level, it is similar to a quiet office and should be unnoticeable from inside most homes.
Climate Suitability
The type of refrigerant a heat pump uses significantly affects its performance in cold weather. Stiebel Eltron uses R134a refrigerant, while Midea 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.
