Renewables ESP Relair

ESP Relair the plug ‘n play heat pump for heating and cooling, no f-gas cert required

The ESP Relair is a standalone heating and cooling unit that can be installed by any competent contractor or builder - no specialist F-gas qualifications needed. It mounts easily against most external walls and runs off a standard plug socket. Installation is almost as straightforward as fitting a fridge.

Only three holes need to be drilled through the wall: two for the air intake and exhaust, and one for a condensate pipe to discharge moisture to a nearby drain. Inside the unit, an integrated heat pump, fan, and heat exchanger extract warmth from the outside air and deliver it indoors. In summer, the process reverses to provide effective cooling, exhausting hot air outside.

Delivering up to 2.35kW of heating and nearly 3kW of cooling, the Relair is fast-acting,  warming or cooling the room quickly thanks to its direct air delivery. Because it heats the air directly, it operates efficiently without needing high temperatures, helping to keep running costs low.

With an intuitive onboard control screen and built-in Wi-Fi, the Relair can also be controlled remotely via an app. It’s ideal for targeted heating or cooling of one or two rooms, especially where a full system install isn’t practical. Simple to fit, energy efficient, and cost-effective - the Relair is an excellent plug ‘n play heat pump solution.
