Rinnai at Falkirk Fire Station

Rinnai N Series 1600i hot water heating units have been installed with a cascade frame at Falkirk Fire Station, Scotland. Installation was carried out by Caledonian Heating & Plumbing,  a specialist heating, plumbing and water management company which offers a wide range of services within the commercial sector throughout Scotland. 

For Caledonian Heating & Plumbing Liam Hush commented, “It was the first time we had used the frame to cascade the two Rinnai units and the installation was quick, simple and straightforward. Our goal on every site is to provide the highest quality service and this was achieved here.”

The Rinnai N Series is a high-performing heating unit delivering temperature accurate, limitless hot water. The N Series units can by powered by a blend of up to 30% hydrogen, and now work on BioLPG. The appliance is described as ‘out of the box’ design engineered and approved to be installed for use on blended gas. 

All Rinnai N Series units are guaranteed to provide limitless volumes of temperature accurate hot water flows, provided fuel and water connection are constant. Falkirk Fire Station installed 2 x Rinnai N Series 1600i units.

The Rinnai Sensei N Series is the first ever continuous flow hot water heating unit manufactured with stainless steel heat exchangers to be available in the UK - this gives a greatly extended working life at optimum performance to each of the four models in the range. Added to this are the market leading extended warranties, that accompany these hydrogen ready appliances.

The four models are: the N1600i giving 954 litres per hour; the N1600e (external) also giving 954 litres per hour (at 50 degrees); the N1300i giving 775 litres per hour and the N1300e also giving 775 litres per hours of temperature controlled at 50 degrees. The two 1600s have load profiles of XXL and are water efficiency class A rated, while the 1300s are load profile XL and are also water efficiency class A rated.

The range are also low-NOx, and the futureproofed continuous flow water heaters have several global patents on main components. The range utilises Rinnai’s patented advanced technology with a 13-1 turn down ratio – the largest on the market – with extremely quiet operation. 

Integral controls on the units enable the water heater to achieve high efficiencies because of advanced burner control and high modulation ranges. This wide range of modulation means that energy usage is completely optimised as the water heater, through smart inbuilt controls, will only heat the water to the temperature required, thus preserving energy.
