Description

Reznor's V3 Series UDAP high efficiency heaters are excellent for space heating applications.

These gas-fired unit heaters are power vented in order to eliminate heat losses up the flue pipe. Power vented models have a higher initial cost than similar “gravity” vented models, but will save money on fuel costs. UDAP heaters are designed for 82-83% thermal efficiency often meeting utility company thresholds for rebate incentives.

All Reznor V3 series heaters are CSA Design Certified, and have a refreshing appearance with a glossy white cabinet finish.
