Reclaim Energy vs Quantum: Which Heat Pump Is Better? (2026)
Quick Verdict
Quantum is the more efficient choice with a higher COP rating, meaning lower running costs over time, while Reclaim Energy offers better protection with a 10-year tank warranty.

Price Comparison
Reclaim Energy starts from $6,600 installed (before rebates), while Quantum starts from $3,250. That is a difference of roughly $3,350 at the entry level. Quantum is the more budget-friendly option upfront, though Reclaim Energy 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. Reclaim Energy achieves a COP of 4.5, while Quantum reaches 4.53. The Quantum is 1% more efficient, which translates to roughly $2 less per year in running costs. Over a 10-year lifespan, that efficiency advantage adds up to approximately $20 in savings.
Warranty Comparison
Reclaim Energy offers a 10-year tank warranty and 5-year compressor warranty. Quantum offers a 5-year tank warranty and 2-year compressor warranty. The Reclaim Energy has the stronger warranty coverage with 10 years on the tank, giving you 5 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. Reclaim Energy publishes 37dB for its quietest model, and Quantum publishes 48dB. The Reclaim Energy is quieter at 37dB. At under 40dB, this is comparable to a quiet library and unlikely to cause any disturbance.
Climate Suitability
The type of refrigerant a heat pump uses significantly affects its performance in cold weather. Reclaim Energy uses CO2 (R744) refrigerant, while Quantum uses R134a. Reclaim Energy has the advantage here. CO2 (R744) refrigerant performs exceptionally well in cold climates, maintaining high efficiency even when temperatures drop below 0 degrees Celsius. R134a-based systems like the Quantum can lose efficiency in colder conditions, though they still perform well in most Australian climates.
Pros and Cons
Reclaim Energy
Pros
- Australian designed
- Split system design allows flexible installation
- Very quiet (37dB)
- Excellent COP of 4.5
- CO2 refrigerant (environmentally friendly)
- Eligible for higher VIC rebate tier
Cons
- Higher upfront cost
- Requires separate indoor tank space
- Limited installer network in some areas
Quantum
Pros
- Four tank sizes from 150L to 340L, the widest range here

- 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 Reclaim Energy if...
- You want a longer tank warranty (10 years vs 5 years)

- You live in a colder climate and want CO2 refrigerant for better cold-weather performance
Choose Quantum if...
- You want a lower upfront cost (from $3,250 vs $6,600)
- You want the best efficiency and lowest running costs (COP 4.53 vs 4.5)
- You want lower annual running costs (~$261/yr vs ~$263/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. Reclaim Energy has models on Solar Victoria's locally made list, which qualify for the higher $1,400 tier.
