The Walloon Church in Delft is an important monumental church in the Netherlands. The monumental interior parts consist of a monumental pulpit, monumental pews, monumental escutcheons and an important burial monument. The monumental Bätz/Witte organ in the church dates back to 1869 and was last restored in 2000. The heating system in the building was originally a direct hot air system, Mark Fohn type 115RH of Mark Heating Systems. The heat capacity of the heating system was 115/77 kW (high/low). The hot air was brought into the church by a re-circulation system with an airflow rate of 7400/5000 m3/h (high/low). The warm air inlet consisted of a single grille at about 3 m above floor level. The outlet was a single grille in the floor. The air was re-circulated for 100 %. The thermostatic device in the church was located near the pulpit at a height of about 3 meters.
