Price Comparison
Stiebel Eltron starts from $3,500 installed (before rebates), while Haier starts from $3,000. That is a difference of roughly $500 at the entry level. Haier 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 Haier reaches 4.49. The Haier is 18% more efficient, which translates to roughly $48 less per year in running costs. Over a 10-year lifespan, that efficiency advantage adds up to approximately $480 in savings.
Warranty Comparison
Stiebel Eltron offers a 5-year tank warranty and 5-year compressor warranty. Haier offers a 7-year tank warranty and 5-year compressor warranty. The Haier has the stronger warranty coverage with 7 years on the tank, giving you 2 extra years of protection compared to the Stiebel Eltron. A longer tank warranty can provide significant peace of mind, as the tank is the most expensive component to replace.
Noise Comparison
Noise is an important consideration, especially for suburban installations where the unit may be close to bedrooms or neighbouring properties. Stiebel Eltron publishes 44dB for its quietest model, and Haier publishes 43dB. The Haier is quieter at 43dB. 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 Haier 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.
