Rinnai’s H1/H2/H3 offers multiple avenues of cost reducing decarbonization across various energy vectors. To create a healthier way of living, Rinnai is expanding customer choices in hot water provision as well as heating domestic and commercial buildings through a wide range of renewable energy systems.
Rinnai’s H3 range of decarbonizing products includes commercial and domestic heat pumps that contain a variety of features: the HPIH range of commercial heat pumps is suited towards schools, restaurants, and small retail outlets. Rinnai’s HPIH Monobloc Air Source Heat Pumps – 21, 26, 28 & 32kW range can allow for up to seven units to be cascaded together or operate alone as one unit. Once joined together Rinnai’s HPIH Monobloc Air Source heat pump can serve increased demand for heating and hot water.
Rinnai’s HPHP series of LOW GWP heat pumps range from 48kw – 70kw. State-of-the-art technology added in the injection process outperforms gas compression technology and ensures that even with outside temperatures of –25 Celsius, heating, and hot water of up to 60 + Celsius can still be delivered.
The company will also be previewing its new division – Rinnai Applied – featuring heat pumps of up to 600kW for major construction projects such as industrial & commercial complexes.
Rinnai’s stand will include the complete range of hot water heating units for all residential and commercial applications – the N series range of condensing water heaters powered by Natural Gas, Hydrogen blends, BioLPG and LNG. The units can be cascaded to handle any size of commercial site – stadia, factories, production units, hotels, accommodation blocks, healthcare centres, hospitals.
Rinnai’s solar thermal water heating systems are a market leading solution that saves up to 3.5x more carbon per m2 compared to conventional solar technology.
Once Rinnai’s solar technology is combined with the condensing hot water heater system, savings in carbon and cost can be made as the units will modulate from 58kw – 4.4kW dependent on the solar input. Therefore, gas will only be used to boost the temperature when needed. Rinnai’s solar hybrid technology harnesses renewable gains whilst maintaining robust and efficient operational performance.
All solar thermal products are precisely aligned with the hot water heating systems & units which are hydrogen blends-ready 20% and renewable liquid fuel (BioLPG and rDME) ready combustion technologies.
Rinnai’s complete range is supported by free training courses, CPDs, FREE design services and extensive warranty options – simply visit www.rinnaiuk.com for further details.
