Non-league football club decarbonise with Rinnai
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 In Fig 1&2.
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.
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.
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.
