Rinnai Condensing Boilers deliver more efficient home heating than traditional boilers, while also providing domestic hot water.

Rinnai Vent-Free Convectors push heat to the farthest reaches of the room, evenly warming larger spaces and maximizing cost-savings.

Most Cash Acme water pressure regulators come preset at 45psi but can be adjusted within a specific range depending on the model. As the downstream water pressure approaches the set pressure, the valve will close off, not allowing water to pass through. As that downstream water pressure drops, typically due to water usage, the pressure regulator will open back up letting water through to recharge the system as long as the demand is needed.

The Rinnai Hydronic Air Handler System easily integrates with select tankless water heaters or boilers to deliver energy-efficient warmth.

Intelligently enable recirculation in your home to have hot water faster when you need it. Rinnai tankless water heaters have built-in pumps with Smart-Circ™ Intelligent Recirculation™ that learns your schedule. No dedicated return line, no problem. A thermal by-pass valve added to the cold water line helps ensure recirculation is enabled, and your unit takes it from there. Plus, take it to the next level with an RWM200 Wireless module (optional | sold separately) to Wi-Fi enable your tankless water heater, and control the schedule from your phone.

If your home does not have a dedicated return line, select Rinnai tankless water heaters can offer faster hot water without adding an additional cold return line. This technology allows for the simple installation of a thermal bypass valve at the fixture farthest away from the water heater. Once installed, the unit temporarily uses the cold water line for recirculation.

Pressure regulating or reducing valves (PRVs) help control downstream water pressure in commercial and residential systems. Each water pressure regulating valve is tested for quality and efficiency before leaving our factory so you know it’s reliable under pressure. Plus, a number of our PRVs are designed with SharkBite connectors to simplify installations and repairs.

For small- to medium-sized new homes or remodels, Rinnai’s high-efficiency models are affordable, compact units you can count on.
