Raypak – Modulation

A typical Raypak modulating boiler equipped with an outdoor reset control will lose less than 2% thermal efficiency across its full range of fire. Unless the heat exchanger area and excess air ratio are exactly varied to match the firing rate (an expensive and complicated proposition), all boilers will exhibit similar characteristics.
