Page 7: Overview
O VERV IE W DESCRIPTION The Mikrofill Rapide Extreme is a domestic hot water generator that combines the advantages of both an instantaneous water heater and a storage system, whilst ensuring that the associated boiler plant operates at its optimum efficiency during domestic hot water generation. The Rapide Extreme is suitable for open vented or unvented applications. -
Page 8: Operation
The primary connections of the plate heat exchanger are extended outside of the casing and made available for connection to a Mikrofill Ethos condensing boiler or other suitably sized boilers. To ensure only the correct minimum temperature is loaded and stored in the cylinder, the primary temperature sensor (TT4) will look for a minimum primary temperature before releasing the loading pump to allow the loading process to begin. -
