Is a heat pump geyser the same as a solar geyser?

No. A traditional solar geyser uses flat-plate or evacuated tube collectors mounted on the roof to heat water directly from sunlight. A heat pump geyser uses a compressor and refrigerant cycle to extract heat from the ambient air and transfer it to the water tank — no roof-mounted panels are required. The Deye heat pump geysers at SP-Energy are heat pump units that can run from solar-generated electricity via a hybrid inverter, which is different from a traditional solar geyser that uses solar thermal energy directly.

What size heat pump geyser do I need for my household?

The 200L Deye model suits households of 2 to 4 people with average hot water usage. The 300L model suits households of 4 to 6 people or properties with higher daily hot water demand such as homes with multiple bathrooms or guests. As a general guide, allow 50L of tank capacity per person per day for comfortable hot water availability throughout the day.

How much electricity does a Deye 4.1kW heat pump geyser use?

The Deye 4.1kW compressor consumes 4.1kW while operating. At a COP of 3 to 4, this produces 12kW to 16kW of heating output per hour of operation. Depending on the incoming water temperature, ambient air temperature, and how often the tank heat is replenished, most households find the heat pump compressor runs for 2 to 4 hours per day to maintain the tank temperature, consuming approximately 8kWh to 16kWh per day at full output.

Can I run the Deye heat pump geyser from my existing hybrid inverter?

Yes, provided your inverter's AC output rating is sufficient to handle the 4.1kW compressor load alongside your other household loads simultaneously. An 8kW or larger hybrid inverter is recommended to comfortably run the heat pump and typical household loads at the same time. Check your inverter's continuous AC output rating before connecting the heat pump geyser to the inverter output circuit.

Can the heat pump geyser help during Eskom outages?

Yes, if your hybrid inverter and battery bank are sized to handle the 4.1kW compressor load during an outage. The heat pump can heat the tank during the day from solar power so that hot water is available in the evening without drawing from the battery. Scheduling the heat pump to run during peak solar hours maximises hot water availability while minimising battery discharge during the outage.
