Rinnai EHPA340VM Enviroflo AR Series Heat Pump – 340L

The Rinnai EHPA340VM Enviroflo AR Series Heat Pump – 340L is designed to maximise available hot water while using more than 70% less energy than a conventional electric storage unit.
Its advanced controller, multiple operating modes, and ability to integrate with solar PV or off‑peak tariffs make it ideal for households seeking lower running costs and reduced environmental impact.
Quiet operation, a wide ambient working range, and built‑in electric backup ensure year‑round reliability and comfort, even in colder climates.

• Eco‑friendly efficiency: R290 refrigerant with very low GWP; cuts energy use by over 70% compared with conventional electric storage, especially when paired with solar PV.
• All‑weather performance: Operates from -7 °C to 45 °C, with built‑in anti‑frost protection and electric boost for peak demand or colder days.
• Smart control: Wi‑Fi‑enabled with electronic temperature control, multiple modes (ECO, Vacation, etc.), off‑peak scheduling, auto‑restart after power outages, and solar‑PV networking.
• Hot water flexibility: Storage type system with up to 70 °C maximum set temperature for strong hot water delivery.

**Energy saving based on a Rinnai Enviroflo AR Series Heat Pump when compared to a standard electric water heater of the same capacity during peak winter load in Zone 3 and 4 based on AS/NZS4234. Savings will vary depending on location (Zone 1-5), type of water heater being replaced, hot water consumption and associated fuel tariffs.

Federal Small-Scale Technology Certificate (STC’s)

Enviroflo’s innovative design allows it to be eligible for Grants through the Federal Governments Small-scale Renewable Energy Scheme, generously covering a proportion of the up-front costs of purchasing and installing the system. These grants are called Small-scale Technology Certificates (STC’s) and are offered based on how sustainable a hot water system is. Your STC rebate value will depend on your installation location, see the map above for your geographic Zone locations.
