Rinnai On-Demand Water Heaters Now Vent with PVC

HVAC Distributors stocks Rinnai’s Ultra Series models, which can be vented with either PVC or CPVC. Previously, Rinnai product could only be vented with polypropylene piping.

Additionally, Rinnai has expanded its Ultra Series line with lower BTU options for single family and smaller multi-family units using natural gas or propane heating. HVAC Distributors has the 160 MBH (RUCS75i) in stock.

RUR Models Provide Installation Flexibility
You can install the Ultra Series RUR models with any plumbing system – even if the homeowner doesn’t have dedicated recirculation return lines, which saves your team time and materials on installation.

These models have a dedicated recirculation pump, internal bypass line and thermal bypass valve to adapt the on-demand water heater to the existing plumbing system. If a homeowner already has a dedicated recirculation return line, the Ultra’s time-and temperature-based Comfort and Economy modes can be programmed to provide the homeowner with customized comfort and energy-savings control over the unit.

Compact & Meets DOE Energy Efficiency Requirements
Rinnai’s on demand water heaters are compact and meet current DOE energy efficiency requirements, making them an attractive option where space is limited for water heater installation.

The Ultra Series features Rinnai’s highest hot water capacity per BTU, providing the ability to support multiple, simultaneous hot water demands and more venting solutions on the same unit:

  • RUR98 model has a 13:1 turndown ratio
  • RUC98 model has a 13:1 turndown ratio
  • RUCS75 model has a 16:1 turndown ratio

HVAC Distributors also continues to carry the Luxury series, which is polypropylene-vented.

Rinnai tankless products are in-stock and can be ordered at any of our HVAC Distributors locations, by phone or through Web Order Entry (use the “HVAC No.”, below, to quickly order what you need).
