As a unique function to this particular Compact Unit, the Heat Pump component is able to be disassembled easily from the Energy Bank component to provide the user with two separate units, effectively becoming two separate products. The standalone 2 horse power heat pump unit or the 300L energy bank unit can then be part of other projects, particularly for those require special space usage. Moreover, the cost of product development is significantly reduced by having 3 independent products with one time investment. Thanks to the manoeuvrability of the design, the air can be discharged from either the top or side (allowing for spatial requirements). Designed to envision lower tooling costs and recyclability, this lengthens the products life cycle considerably and provides a more sustainable solution for customers. Using rotational moulded water tank material PEX, combined with Aluminium sand casting allows the design to remain WaterMark approved, durable in every environment.
