Rinnai recently supplied a growing high street gym estate with a custom-built ‘gym pack’ that includes everything from design to delivery of a complete hot water system in one ‘pack’ delivered direct to site.

The site has reported excellent results from the systems, which have been installed in multiple sites over the UK, with more rolling out over the next couple of years.

Chris Goggin, associate director at Rinnai, said: “Simply supplying a water heater unit (or multiple units) has become an antiquated notion that simply is not good enough. ‘System’ thinking, where we deliver to site the complete package, is what is going to give the gym chain the edge over the competition.

“The Rinnai system virtually guarantees endless amounts of hot water at useable temperatures, all on demand. Who wants a cold shower after a workout? And what gym chain wants to lose a client because of cold showers?"

The Rinnai total gym solution includes water heaters, flues, scale protection, unvented cylinders, valves, prefabrication racks, advanced BMS controls, and water sampling equipment – specified, designed and delivered by Rinnai.

Mr Goggin continued: “The heat generator on the system is Rinnai’s HD1500i which offers 95% gross efficiency, which is maintained for the lifetime of the system due to the design principles and controls.”

Rinnai HDC1500i regulates water temperature to within +/- 1ºC via a ‘smart’ digital controller without any variation of temperature at the outlet even when water is drawn off elsewhere. All models have full electronic ignition, no pilot light and operate on demand only, so there is no gas consumption when the unit is idle.

The system can accommodate as many HD1500i units as necessary depending on the size of the gym/hot water need on a bespoke cascade frame, with bespoke designed common header flue – also including electrolytic scale prevention devices.
