Rinnai Heat Pumps On Site At Stockport College


Stockport College has recently completed a £25m campus redevelopment programme to ensure that all courses have the highest standards of facilities and resources.

The college also aims to be a sector leading employer so that staff thrive and deliver the highest quality of education and experience to all the students and stakeholders.

Rinnai hot water heating products have been used by Stockport College within their training facilities. The state-of-the-art commercial heat pumps, continuous flow water heaters and boilers will be used as training equipment for the next generations of plumbing and heating engineers.

This includes the Rinnai 11i light commercial/domestic range of tankless continuous flow water heaters plus the new i32 Inverter Monoblock LOW-GWP Heat Pump (4kW) and the 150 Litre Heat Pump Thermal Cylinder Single Coil.

Rinnai’s range of Monobloc air source heat pumps are available in an assortment of variants, from 4 to 110kW. Stockport has taken the 4 kW models. The air source Low-GWP heat pump technology allows up to seven units to be cascaded together, making the Rinnai heat pump range an ideal choice for any heating or hot water demand. The innovative ability of the system to switch between heating, hot water, and cooling mode ensures that the Rinnai range has flexibility and durability as standard.

The units omit minimum acoustics via an installed ultra-low sound capability making Rinnai heat pumps suitable for any area with prohibitive sound legislation. Rinnai’s range operates within compliance of all stringent sound standards ensuring low-sound functionality.

All Rinnai heat pumps use R32 or R290 refrigerant, renowned for reducing electricity consumption and for holding a lower global warming potential (GWP). Rinnai’s HPI commercial heat pump range is ratified with an ERP rating of A +++ and includes an ability to switch between settings of heating, hot water and cooling.

Also on site at Stockport College’s training facilities are the Zen and Zen Plus home hot water & heating systems which marry established and proven manufacture durability with new technologies to offer great energy efficiencies, user control and comfort. The Rinnai Zen and Zen Plus system will increase comfort and reduce energy usage whilst also providing a highly economically solution for today’s changing marketplace.

Some of the features of Zen & Zen Plus are: IOT controller as standard; Fast heating mode; DHW pre-heat function - saving wasted water; Energy monitor function allows user to monitor energy usage; flue runs up to 30 meters, Rinnai boiler App for android and IOS.

The Rinnai heat pumps and cylinders and the 11i models, plus some of the Rinnai Zen domestic boilers, will be used in the training facility where students will learn about installation, stripping down, pipework, flues - the whole Nine Yards!

The 11i units are an advanced variant of traditional multipoint water heaters, and they are far more efficient than traditional storage systems. They are ideal for sites such as restaurants, fast food outlets, guest houses, small hotels, day care centres and any other type of light commercial or domestic application requiring high volumes of water at intermittent times of the day, delivered at accurate temperatures to ensure user comfort and safety.
