high temperature heat pumps – Building Specifier

A Gloucestershire non-league football club is aiming to decarbonise the whole of its ablutions by installing a high temperature R290 heat pump solution for the DHW requirements in the club’s washrooms and showers. The target for the football club is to reduce carbon by installing a state-of-the-art Rinnai commercial heat pump system.

Rinnai produced full data modelling for the site, that focuses on capital and operational costs whilst also reviewing the carbon intensity of different hybrid and heat pump systems so that all the costs and performance parameters where completely visualized for the client. This transparency is critical to users, who can now be made aware of the full costs associated with electrical systems. The operational costs are modelled against the projected cost reductions in electricity prices from valid sources. A breakdown of fuel costs is provided below.

Figure 3: Energy prices and carbon factors used for analysis study.

When comparing OPEX, CAPEX and carbon reductions information pertaining to the current system is not available, however it is known that the football club uses a gas-powered system. Therefore, a comparison between a Rinnai Heat Pump and Rinnai natural gas powered N1300 can be made and illustrated with visual graphs.

The first graph will detail the amount of carbon reductions made possible through installing a Rinnai high temperature heat pump when compared to a natural gas powered N1300. Rinnai’s gas system is represented in blue whilst Rinnai’s High Temperature Heat Pump is highlighted in purple.

Figure 4: Carbon Emissions Lifecycle comparing a H1 and a H3 system for DHW

The above graph demonstrates the carbon reductions achieved through a Rinnai high temperature heat pump. Over five years a gas fired system will emit over 5 times the amount of carbon emissions when compared to a Rinnai heat pump. Overall, there is an 81% reduction in carbon offshoots over 5 years.

Below is another graph that details the cumulative running costs over a 5-year period. The OPEX costs are compared to a Rinnai N1300 natural gas appliance.

Figure 5: Cumulative Running Costs (OPEX) comparing a H1 and a H3 system for DHW

The above graph illustrates the difference in cost between a Rinnai N1300 (blue) and a High Temperature Heat Pump (purple). Over a 5-year period there is a 23% increase in operational costs. A Rinnai natural gas system will cost £18,844.71, whilst a Rinnai High Temperature Heat Pump would cost £24,296.58.

Rinnai will continue to provide transparent examples of carbon reducing technology that results in cleaner local air quality. Rinnai’s product offering includes multiple technologies that are capable of being powered by current and future clean energies. All commercial operations and premises that require a reduction in emissions should consider manufacturers that can offer a selection of appliances capable of accepting various clean and current fuels.

Rinnai and Naked Energy Launch Innovative Solar and Heat Pump Integration Whitepaper for Sustainable Heating Solutions.

Rinnai and Naked Energy have collaborated to introduce a whitepaper as a precursor to a CIBSE certified CPD, the paper entitled Sustainable Synergy: Integrating Heat Pumps and Solar Thermal to Satisfy the Hot Water Needs of an archetype hotel.

The whitepaper researches and evaluates in fine detail the financial and operational outputs of a DHW solution comprising of high temperature heat pumps and solar thermal collectors utilized in an obvious commercial setting – an archetypal hotel.

Rinnai’s Sean Ehlen, together with Zanil Narsing of Naked Energy, have prepared both the whitepaper and CPD to provide the detailed data for building services consultants, system designers, main HVAC contractors and installers to consider when approaching commercial property installations that require strong and sustained system efficiency and maximized reductions in energy usage and carbon loads.

Within the main body of this paper various DHW systems operational capabilities were compared when satisfying the hot water demand of an archetype hotel. Simulation calculators were produced to highlight how the key metrics of each DHW system compared over a 20-year period.

The findings of this study demonstrate how parallel dual storage SAHP’s (Solar Assisted Heat Pumps) reduce the carbon loads by 96% whilst requiring 49.5% less primary energy, compared to a conventional gas-fired water heater system, in turn maximizing the systems efficiency.

The data extrapolated from this whitepaper further suggests that Rinnai’s parallel dual storage SAHP (Solar Assisted Heat Pumps) system should be considered by sites and all major end-users such as institutional domains, office blocks, retail malls and chain-hotels. Contractors and consultants are now with an expectation of clients’ requiring carbon reduction without diminishing performance. All sites are now expected to reduce carbon emissions whilst installing systems aligned with future building standards.

Rinnai’s latest CPD is part of an overall strategy that aims to supply UK customers with detailed analysis of decarbonising technology towards commercial applications. Rinnai will continue to offer valuable services and information to UK customers that assist in easy and appropriate product selection that delivers operational efficiency.

Rinnai’s design team offer a range of services that include cost and carbon calculations as well as a “Site Consultation Form” that details on-site data of current heating and hot water system capabilities. Customers can view the results in a rapid low carbon replacement suggestion by a professional team member.
