A heat pump water heater produces domestic hot water using the principle of thermodynamics. It’s more environmentally friendly and cost-effective in operation compared to traditional electric water heaters.
This type of water heater combines a heat pump to produce domestic hot water. The heat pump captures calories naturally present in the air (a process called aerothermal energy) to heat the water. The result is an eco-friendly and economical solution, as the energy source (air) is renewable, free, and inexhaustible.
While heat pump water heaters still consume electricity, they use significantly less compared to standard electric water heaters, making them a more sustainable option. It will produce more energy for the same electricity consumption.
It consists of a tank and a heat pump, which may be integrated or separate.
The heat pump collects air through the fan directing it through the evaporator, which heats the fluid. This heat is transferred to the water in the tank via a condenser. The tank stores the hot water until it’s needed.
If the heat pump cannot produce enough hot water (e.g., during extended periods of intense cold or system malfunction), an integrated resistance heater takes over to ensure a consistent supply. These heaters also include anti-corrosion technologies such as magnesium anodes, ACI (active current anode), or ACI Hybrid for added durability.
Heat pump water heaters are available in several configurations, each tailored to different installation setups and needs. These variations allow them to adapt to various types of homes and spaces, ensuring optimal performance and efficiency:
Atlantic’s Heat Pump Water Heater Range:
Heat pump water heaters can be installed in houses or apartments, new constructions, or renovations. They can function in heated or unheated rooms, depending on the model and configuration.
Models that draw ambient air must be installed in an unheated room with a minimum temperature of 5°C and a volume of at least 20m³ to ensure optimal operation of the heat pump. Suitable locations include a laundry room, garage, basement, or pantry.
In contrast, outdoor air and split models are more flexible. These can be installed in either heated or unheated rooms with a year-round minimum temperature of 1°C, such as a garage, pantry, laundry room, entryway, or basement. The wall-mounted version of the Calypso ambient air model can even be installed in a kitchen or bathroom.
Daily use of this equipment is straightforward as it functions similarly to a traditional water heater. Minimal maintenance is required, with a recommended inspection every two years.

What capacity for my water heater?
At Atlantic, heat pump water heaters are available in the following capacities: 100L, 150L, 190L, 200L, 230L, 250L, 260L, and 270L. These options cater to a variety of needs, from households of two people to larger families with multiple water outlets (e.g., showers, sinks, and basins).
For the installation and maintenance of a heat pump water heater, it is essential to work with a professional. These devices are more technical than standard water heaters, and proper installation ensures long-term reliability.
We recommend contacting several professionals to compare quotes. Each installer should visit your home to provide a tailored estimate and guide you on any additional work that may be required.
