Description
Reclaim REHP-CO2-315SST-V2CO₂ Heat Pump Hot Water
Perfect for 3–5 people. The Reclaim REHP-CO2-315SST-V2 uses natural CO₂ (R744) refrigerant with a COP of up to 5.0 — saving up to 80% on hot water costs. Ultra-efficient split system with freeze protection to -10°C. Australian designed and manufactured. Backed by a 5-year compressor and 10-year tank warranty.
CO₂ Technology — The Most Efficient Natural Refrigerant
The Reclaim REHP-CO2-315SST-V2 uses R744 (CO₂) — a 100% natural refrigerant with a GWP of just 1 and zero ozone depletion potential. CO₂ technology excels in cooler conditions, delivering outstanding efficiency where conventional heat pumps struggle most.
Up to 80% Less Energy (COP 5.0)
With a COP of up to 5.0, the Reclaim CO₂ system produces up to 5 units of heat for every 1 unit of electricity consumed — among the highest efficiency available in the Australian market.
CO₂ Natural Refrigerant (GWP=1)
R744 (CO₂) has a global warming potential of just 1 and zero ozone depletion potential — making it the most environmentally responsible refrigerant available. Future-proofed against all known regulatory changes.
Freeze Protection to -10°C
CO₂ technology performs exceptionally well in cold weather. The Reclaim system operates from -10°C to +43°C — reliable hot water across all Australian climates.
Australian Designed & Manufactured
Reclaim Energy is an Australian company. The systems are designed and manufactured locally, meaning local support, parts availability, and a product built for Australian conditions.
STC & ESC Rebates Available
Qualifies for federal Small-scale Technology Certificates (STCs) and NSW Energy Savings Certificates (ESCs). We handle all paperwork and pass the saving directly to you at point of sale.
Stainless Steel Tank
The REHP-CO2-315SST-V2 features a stainless steel storage tank for long-lasting corrosion resistance. Backed by a 10-year tank warranty. WARRANTY CONDITIONS APPLY.
Compressor & Tank Installed Separately
The Reclaim is a true split system — the CO₂ compressor unit and storage tank are installed separately. The compressor can be placed outdoors or away from noise-sensitive areas, while the tank goes exactly where you need it.
- Compressor and tank installed separately
- No refrigeration mechanic required for installation
- Flexible indoor or outdoor tank placement
- Compact compressor unit for tight spaces

Outdoor CO₂ Unit — Indoor Tank is Silent
The Reclaim CO₂ SST 315L is a split-system heat pump — the outdoor CO₂ compressor unit does the work while the 315L stainless indoor tank stores hot water in complete silence. CO₂ compressors produce less mechanical noise than conventional systems, and anti-vibration mounts keep the outdoor unit below 50 dB.
- Split system — outdoor compressor unit, silent indoor tank
- CO₂ (R744) refrigerant compressor — lower inherent noise
- Outdoor unit below 50 dB — residential noise compliant
- Anti-vibration mounted outdoor unit
- Boost timer for off-peak overnight heating

315L SST — Zero-Maintenance Stainless Tank
The REHP-CO2-315-SST uses a Duplex stainless steel cylinder — no sacrificial anode, no corrosion, no tank maintenance ever. Rated for coastal and high-chloride environments where glass-lined tanks degrade quickly. Australian-made by Reclaim Energy. Backed by a 10-year cylinder warranty.
- Duplex stainless steel cylinder — corrosion-proof for life
- No sacrificial anode — completely maintenance-free tank
- Rated for coastal, high-chloride, and hard water zones
- Australian-made by Reclaim Energy
- 10-year cylinder warranty. WARRANTY CONDITIONS APPLY.
