Emerald All-In-One Select 220L (E) Heat Pump

The story

What Emerald is actually about

Emerald Energy is an Australian renewables brand that builds hot water heat pumps alongside solar and storage gear, so the units are designed from the outset to be told what to do by your roof rather than by a timer.

The range splits into two: the All-In-One Select is the value pick at 58 L/h recharge and 50 dB(A), while the All-In-One Pro adds an inverter DC compressor, a diamond-enamel carbon steel tank, 49 dB(A) running and a 108 L/h boost recharge on top of a longer warranty.

Everything in the all-in-one range runs R290 — global warming potential of 3, against roughly 1,430 for the older R134a gas still used elsewhere — and the E models add an integrated electric element so the unit keeps making hot water down to -15°C.

Why people pick it

Emerald standouts

Solar Soaker

Reads your smart meter and heats when the roof is exporting, so your hot water runs on spill solar instead of grid power.

Emerald App

Schedules, Smart Actions, Silent Mode, Boost and live tank temperature — all from the phone.

R290 across the range

GWP of 3. Future-proofed against refrigerant phase-downs, and better cold-weather performance than R134a.

Pro tank warranty

Seven years on the Pro tank, eight if you register it, with five years labour — one of the better deals at this price.

Straight talk

Who Emerald suits — and who it doesn't

Good fit if…

  • Solar households wanting automated self-consumption
  • Families sizing 220L to 320L
  • Buyers who want R290 without premium money

Field pros

  • • R290 natural refrigerant (GWP 3) across the all-in-one range
  • • Solar Soaker heats on spill solar automatically
  • • Pro tank warranty runs 7 years (8 registered) with 5 years labour

Probably not for you if…

  • Very cold alpine sites better suited to CO₂
  • Buyers wanting a split system — Emerald makes them, but we currently only supply the all-in-one range

Field cons

  • • Select series drops to 5 years tank and 2 years labour
  • • We only supply the all-in-one range — Emerald's split system isn't in our current lineup

Emerald warranty

  • All-In-One Pro: 7 years tank (8 registered), 5 years system, 5 years labour
  • All-In-One Select: 5 years tank and system, 2 years labour
