Rinnai's Latest CPD Studies The Significant Carbon and Expenditure Savings That Can Be Achieved By Reducing Traditional Storage


Rinnai has released its latest CPD, ‘Carbon and Economic Benefits of Zero Storage in Hot Water Systems’ with all details on  Rinnai’s latest CPD demonstrates carbon and cost savings achieved through investing in hydrogen blend ready and BioLPG ready continuous flow hot water heaters.

Recent media attention has been directed towards the issue of rising energy and living costs. Rinnai is continuously working to produce completely reliable products that benefit the customer in terms of performance, finance, and convenience.

Rinnai’s instantaneous hot water systems have been rigorously analysed and found to offer significant savings in five key areas, when compared to traditional storage systems:

Operational costs;
Capital cost;
Carbon footprint;
Space and weight.

Approximate savings achieved by replacing a traditional storage-based system with a commercial Rinnai continuous flow hot water system amount to:

15-20% of the running cost,
30% of the upfront cost,
15-20% in carbon footprint,
60% in space,
80% in weight.

These cost and carbon savings calculations can be measured in a formula divided into 3 main steps that produce reliable and accountable results.

The first step collects and processes data from previous real-life projects. This data is used to understand more about peak loading conditions and usage patterns. The second step sizes the system according to the loading. The third step is used to calculate the CAPEX, OPEX, Carbon Emissions, Efficiency, Energy, Performance, Plant Space, and weight.

Rinnai is a registered provider of CPD courses with both CPD UK and CIBSE. All courses are designed to facilitate a better technical understanding of low carbon heating, hot water delivery systems. Rinnai’s CPD courses are simply found by keying in “training” into the Rinnai website search area, located at the top left side of the opening webpage. All CPD’s are free to all.
