Olsen unit heaterWhen considering a condensing boiler for your home Olsen provides you with a choice.

We offer a fixed capacity boiler rated at 90% AFUE. The 95M is a modulating boiler with an AFUE of 95%.

The modulation feature of the 95M allows the boiler to change its heat output relative to actual current load requirements. Modulating boiler applications are best for larger homes with many or small zones.

In these applications the boiler will modulate to a lower output versus cycling on and off when the smaller zones call for heat, reducing temperature swings and maximizing comfort.

These modulating boilers are also ideal for small commercial applications.
