The Biasi Riva Wall Hung RI-FP-NAT Natural Gas boiler is a compact home heating and hot water solution, suitable for almost any home. The same boilers that have been available in Europe for ten years are now available in North America. The Biasi Riva LP is a Non-Condensing mid-efficiency boiler with an efficiency rating of 82%.
The Biasi Riva boiler RI-FP-NAT is factory shipped with all primary system components installed and contained within the boiler, making installation of these units fast and simple. All Riva boilers are ASME and CSA certified to ensure the utmost safety and quality. The Riva RI-FP-NAT is a combi On-Demand Hot Water built-in with the use of a flat plate heat exchanger.
To reduce fuel consumption, the RIVA Wall-Mounted RI-FP-NAT Boiler operates ”on-demand”. It contains less than 2 quarts of water. RIVA’s heating output of 101 MBH can be adjusted to as low as 37 MBH to match your home’s heating requirements while maintaining full output for hot water production. When the Thermostat calls for heat a series of safety checks commence before the electronic ignition, (not a wasteful pilot flame) starts the main burner. During operation, the gas flow rate is constantly adjusted to the required temperature in the main boiler circuit to be within (1.5F) whether it’s the Thermostat calling for heat. After each call for heat, the heat exchanger is purged of residual heat by the circulator resulting in no standby losses.
