The Enviroheat 200EH1-14 is a compact all-in-one air-source heat pump hot water system designed for smaller Australian households. It features a 195-litre actual storage volume, programmable timer settings, multiple operating modes and a 1500W auxiliary heating element for dependable everyday hot water.
Model: 200EH1-14
Actual tank volume: 195L
Model: 250EH1-15
Actual tank volume: 246L
The Enviroheat 200EH1-14 absorbs heat from the surrounding air and transfers it into the water stored inside the integrated tank. This reduces reliance on direct electric heating compared with a conventional electric storage water heater.
Its compact monobloc design combines the heat pump and storage cylinder into one unit. The integrated digital controller provides timer programming, temperature adjustment, operating mode selection and hot water capacity monitoring.

A practical choice for smaller households and properties with moderate hot water requirements.
Supplied with a 10A plug and cord for connection to a suitable weatherproof power outlet.
The listed sound pressure level of 46dBA supports quieter everyday operation.
ECO mode can be programmed to operate during daytime solar generation periods.

The built-in digital control panel provides easy access to water temperature settings, timer programming and operating modes. It also displays the available hot water level and system fault information.
Automatically manages heat pump operation to maintain reliable hot water availability based on demand.
Runs during programmed operating periods and is recommended for households with solar power.
Activates the 1500W auxiliary electric element for faster heating when extra hot water is required.
Keeps the system off while you are away and restarts it before your selected return date.
The system automatically raises the stored water temperature to 63°C once every seven days for sanitation.
Allows the electrical heating element to maintain hot water supply temporarily if the heat pump experiences a fault.
A thermostat and over-temperature protection device support safe system operation.
Prevents unintended controller changes while allowing normal system operation to continue.
The fan draws surrounding air into the heat pump.
The evaporator collects available heat energy from the air.
The compressor increases the refrigerant temperature.
Heat transfers through the micro-channel condenser into the tank.
The process continues until the selected water temperature is reached.
The unit must be installed vertically on a solid and level surface capable of supporting its filled weight.
The system requires sufficient airflow and must not be installed in a fully enclosed space.
Allow approximately 400mm above the system and suitable surrounding clearance for airflow and servicing.
Condensate water must be able to drain freely to an appropriate drainage point.
Share your current hot water system and property details.
We confirm available space, ventilation, drainage and electrical suitability.
Qualified installers complete the required plumbing and electrical work.
The system is filled, tested and programmed for correct operation.
Start enjoying reliable heat pump hot water for everyday use.
The relief valve lever should be operated at least once every six months.
The system should be drained and flushed during a major service approximately every five years.
The tank sacrificial anodes should be inspected periodically and replaced when required.
The condensate discharge pipe should be checked regularly for blockages or restricted flow.
