Air recuperators allow for an increase in efficiency of HP heaters. Owing to an air recuperator the performance of HP heater is greatly improved.

A Hiton recuperator is a compact construction consisting of a tubular heat exchanger and a case with an efficient blow-in ventilator, which constitute a single unit. The recuperator is installed directly behind the heater, mounted on the vertical segment of the exhaust pipe.

Additionally, there is an option of directing the retrieved heat through an air duct directly into another room e.g.: offices, staff rooms etc.
