Olsen OLSSV Boiler Overview

The Olsen OLSSV is a discontinued gas-fired, modulating condensing boiler with an efficiency rating of 95% AFUE. It was designed for wall hung installation, with the wall bracket included. The unit’s stainless steel fin tube heat exchanger was vertically mounted and self-cleaning to remove water deposits and prevent scaling. The OLSSV could be paired with an H2O water heater tank to provide both residential heat and domestic hot water. A text display control offered features including outdoor reset, priority domestic hot water, and management of up to 16 units in Multiple Boiler System. It also offered two basic settings with factory pre-sets, one for central heating and one for domestic hot water.
