Why choose the ELIOS EMC Series 24,000 BTU R-454B?

Elios wall-mounted ductless heat pumps offer versatile, high-end solutions for modern residential and professional environments. Designed to adapt to seasonal variations and ensure comfort all year round, they feature an elegant and modern design as well as various installation possibilities.

A heat pump is an all-in-one solution that provides both heating and cooling to maintain an optimal indoor temperature in all seasons. Designed for harsh winters, the Central-Elios continues to provide heat even when temperatures drop. Thanks to Heat+ technology, systems deliver up to 100% of their rated capacity at -15°C, and maintain a high coefficient of performance (COP) down to -30°C — without skyrocketing your energy bill.

• Air conditioning mode: like a traditional air conditioner, the heat pump extracts heat from inside the house to reject it outside, thus cooling the interior space.

• Heating mode: in reverse mode, the heat pump captures the heat present in the outside air and transfers it inside to warm the house. This dual functionality ensures constant and effective comfort all year round, with a single system.
