Price Comparison
Haier starts from $3,000 installed (before rebates), while Quantum starts from $3,250. That is a difference of roughly $250 at the entry level. Haier is the more budget-friendly option upfront, though Quantum 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. Haier achieves a COP of 4.49, while Quantum reaches 4.53. The Quantum is 1% more efficient, which translates to roughly $3 less per year in running costs. Over a 10-year lifespan, that efficiency advantage adds up to approximately $30 in savings.
Warranty Comparison
Haier offers a 7-year tank warranty and 5-year compressor warranty. Quantum offers a 5-year tank warranty and 2-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 Quantum. 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. Haier publishes 43dB for its quietest model, and Quantum publishes 48dB. 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. Haier uses R134a refrigerant, while Quantum 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.
Pros and Cons
Haier
Pros
- 43 dB(A) at 1 metre on the 200L and 250L, quiet for an all-in-one
- Backed in Australia by Fisher and Paykel
- 5 years parts and labour, with the cylinder covered for 7
- Propane (R290) refrigerant
- 330L is the largest all-in-one tank in this comparison
Cons
- Country of manufacture is not published
- The 330L drops to a published COP of 4.00
- Not on the Solar Victoria locally made list, so it earns the lower Victorian rebate tier
- The 330L is wider and deeper than most, so check the space before you order
Quantum
Pros
- Four tank sizes from 150L to 340L, the widest range here
- A 150L option, which almost no other brand offers
- Australian company with a manufacturing facility at Seaford, South Australia
- Propane (R290) across the range
- On the register since 2014, so the models have a long track record
Cons
- Not on the Solar Victoria product list at all, so a Quantum does not qualify for the Victorian hot water rebate
- Only 2 years on the electrical and refrigeration parts, the shortest here
- Quantum publishes no labour warranty term
- The product pages and the 270L data sheet disagree on the minimum operating temperature (-10C against -15C)
- 50 dB on the 150L and 200L
Which Should You Choose?
Choose Haier if...
- You want a lower upfront cost (from $3,000 vs $3,250)

Choose Quantum if...
- You want the best efficiency and lowest running costs (COP 4.53 vs 4.49)
- You want lower annual running costs (~$261/yr vs ~$264/yr)
Buying in Victoria? Stack up to $2,700 in rebates
Whichever brand you pick, Victorian households can stack the Solar Victoria Hot Water Rebate ($1,000-$1,400), the Victorian Energy Upgrades discount ($500-$2,000), and federal STCs ($500-$1,200) ahead of the 1 March 2027 gas ban deadline.
