Rinnai tankless rack systems do not use boilers. The system uses manifolds that work more like pipes than like boilers. No ASME certification is required because it does not heat water in a tank. A classic boiler stores a considerable amount of energy. That energy becomes a maintenance problem in itself, a problem serious enough to require regular maintenance.
In Rinnai tankless rack systems, if a manifold breaks, very little energy is stored and there is no pressure to be released. It comes out at the same pressure as the water lines. It is about the same temperature as the water at the hot water tap. In the worst possible case, a small amount of steam might be released. Relief valves and regular inspections make a good system inherently safer.
In many regions of the country, you have to maintain a special license to install a boiler. This may require periodic recertification, fees, and paperwork. The Rinnai Tankless Rack System (TRS) makes doing business easier as no ASME certification is required. Most importantly, by offering the TRS, you are providing a state-of-the-art water heating technology versus traditional boilers.
A tankless heater does not collect sediments the way that a hot water tank does. All of the water moves and not much settles and collects. There is no “sediment bowl” to empty and very little residue.
The Rinnai system is Energy Star Certified and features a thermal efficiency of 96 percent. These heaters heat only the water that the customer uses, and they cost a lot less to operate.
The Rinnai tankless rack system consists of from two to six C199 units attached to a rack. Each unit delivers 199,000 BTUs per hour from natural gas or propane. Two sizes are available that mount on the wall. There are several freestanding configurations.
The TRW/TRS assemblies weigh from 175.5 pounds to 518. They come pre-assembled, already mounted on a rack with pipes attached. They are sized to fit through 32-inch doorways and in elevators. The TRS/TRW systems also work well installed outdoors. The systems can also be ordered with a common venting system installed so that up to eight units can share one intake and one exhaust.
When your customer asks for a boiler, work with them and find out whether a Rinnai Tankless Rack System (TRS) will better suit their needs better. For more details on our selection, venting, installation, and a quote, contact Waterheaters.com today.
