Introducing the Rinnai 807000212 Primary-Secondary Heating Kit, designed specifically for Rinnai's i-Series condensing boilers. This heating kit is an essential addition for homes or businesses that require a more efficient and reliable heating solution.
The primary-secondary heating system separates the feed and return water flows, ensuring that the clean water entering the boiler is free from any contaminants or impurities. In turn, this results in improved boiler performance, increased energy efficiency, and prolonged system lifespan.
This Rinnai heating kit includes a primary pump, a secondary pump, and a secondary return manifold. The primary pump is responsible for circulating the water from the heat source to the radiators or underfloor heating system. The secondary pump, on the other hand, circulates the water from the boiler to the primary side, and then back to the boiler to be heated again. The secondary return manifold collects the water from the radiators or underfloor heating system and returns it to the secondary side of the boiler.
The Rinnai 807000212 heating kit is compatible with the Rinnai i-Series boilers, including the Rinnai Infinity and Rinnai Symphony models. It is made of high-quality materials, ensuring durability and reliability, even in the most demanding heating environments. The kit also features easy-to-install components and straightforward installation instructions, making it an ideal solution for both professional installers and DIY enthusiasts.
In summary, the Rinnai 807000212 Primary-Secondary Heating Kit is an essential accessory for any Rinnai i-Series boiler, offering improved performance, increased energy efficiency, and prolonged system lifespan. With its high-quality components, easy installation, and compatibility with various Rinnai i-Series boilers, this heating kit is an excellent investment for any home or business looking for a reliable and efficient heating solution.
