Rinnai UK’s team of Heating & Hot Water System Designers have provided a well-recognized hotel, spa and golf resort in the north of England with plans to install one of two new systems that are proven to reduce cost, carbon emissions and improve energy efficiency.
As well as adding 31 executive rooms the 200-bedroom hotel, spa and golf resort will exchange their two traditional storage tank hot water systems for a Rinnai 20% Hydrogen blend ready continuous flow gas fired water heaters and Hybrid air source heat pump system. The hybrid hot water system contains a 10% heat pump prefeed making the best practical use of the existing space and fuel infrastructure. By completing all refurbishments, the hotel, spa and golf resort hope to increase their rating from 4 to 5 stars.
Rinnai design support is on hand to model and design Hybrid heating and hot water systems, for support with your next project call 0300 373 0660 or visit https://www.rinnai-uk.co.uk/contact-us/help-me-choose-product today.
UK commercial and domestic properties are adopting carbon reducing energies in replacement of fossil fuels as part of an international shift that embraces renewably generated energy. By installing a Rinnai hybrid heating system, carbon savings of 267,000 kg over five years can be made when compared to a H1 gas system.
Energy efficiency is a key aspect of system operational performance that affects cost and system durability. The Rinnai UK design team have measured the savings in energy usage that a Rinnai hybrid heating system will achieve when compared to a gas system. Energy savings of 38.5% will be made upon installation of a Rinnai hybrid hot water system utilising state of the art continuous flow water heaters and LOW-GWP heat pumps. The graph below demonstrates proven energy savings upon investment.
Rinnai’s hybrid heat pump range is designed to satisfy domestic and commercial hot water and heating requirements. The company’s innovative heat pump systems include an ability to switch between settings of heating, hot water and cooling. Recently an R290 heat pump model was added to the expanding range. This innovative new range of air source heat pumps utilizes R290, a LOW scoring GWP (Global Warming Potential) refrigerant.
R290 allows for several operational benefits: for example, the energy efficient units enable a water temperature up to 75 degrees Celsius and R290 usage provides compliance alongside the European F-Gas Regulation which focuses on phasing down refrigerant environmental impact, as well as having a LOW-GWP of 3.
Rinnai’s range of commercial air source heat pumps omit minimum acoustics via an installed ultra-low sound capability making Rinnai heat pumps suitable for any area with prohibitive sound legislation. Rinnai’s heat pumps, hybrid solar thermal and heat pumps and electrical instant and direct water heaters are part of the H3 range of products. All new models are designed to embolden decarbonisation, energy efficiency and reduce customer costs.
Continuous flow hot water heating from Rinnai includes two N1600 models: the N1600i (internally mounted) provides 954 litres per hour of temperature controlled hot water at 50 degrees.; the N1600e (externally mounted) is also capable delivering 954 litres per hour at 50 degrees. The two 1600s have load profiles of XXL and are water efficiency class A rated. The condensing gas fired water heaters have a 13:1 turndown ratio making them ideal for Hybrid water heating as they will modulate the gas input to suit the temperature lift required which in turn maximises renewable system gains.
Other features include: flue up to 30+ metres for concentric, turbo fan, built-in controller as standard on both internal and external models, cascade cable assembly allows up to 24 water heaters to be connected and function as one total and complete system, built in flue damper, air inlet filter, frost protection – minus 15°C on the internal versions and minus 20 °C on the external versions, new PCB design, controller as standard – lockable, set up of appliance, temperature set up to 75°C and maintenance monitor for engineers.
Rinnai UK’s design team can measure the specific requirements of any residential or commercial property and suggest an appropriate heating and hot water system that compliments the specific dimensions of each site. Rinnai is continuing to produce innovative technology that provides low carbon solutions to all UK customers across a range of applications.
