Rinnai’s latest CPD is: ‘Retrofitting Heat Pumps into Leisure Centre Through CCA & SPF Analysis‘.
The CPD presents a comprehensive case study on retrofitting heat pump systems into leisure sector buildings, specifically focusing on a leisure centre undergoing renovation to meet low Global Warming Potential (GWP) targets.
Heat Pumps can be readily fitted to existing or even older properties in both residential and commercial sectors. This particular CPD analyses the specific needs of retrofitting in terms of design and appliance installation as well as meeting the site’s required heating and hot water demand. Further attention is applied to how the concept of retrofitting demands detailed study in regard to maximising energy efficiency.

The approach adopted by this new CPD focuses on manufacturer and supplier perspectives by comparing system options using detailed CCA (Comparative Cost Analysis) and SPF (Seasonal Performance Factor) methodologies.
There are 4 key stages of Rinnai’s new CPD “Retrofitting Heat Pumps into Leisure Centre Through CCA & SPF Analysis.”
1. Design Considerations for Heat Pump Retrofitting
- Exploration of the design process from a manufacturer/supplier’s viewpoint.
- Importance of transparency in building specifications and legacy system data.
- How flexibility in recovery rates and installation space can lead to more tailored and effective system proposals.
2. Understanding Performance Metrics
- Limitations of COP and SCOP in evaluating system efficiency.
- Introduction to SPF as a more holistic and accurate metric for assessing heat pump performance over time.
- Why SPF is essential for clients to fully understand the operational and environmental impact of their systems.
3. CCA & SPF Analysis
- Comparative analysis of various system options using CCA and SPF methodologies.
- Use of analytical graphs and schematics to illustrate performance, cost, and carbon implications.
- How system sizing and design can deliver a complete feasibility portfolio - covering technical, financial, and practical aspects.
4. Case Study: Leisure Centre Retrofit
- Real-world application of heat pump retrofitting in a leisure centre.
- Insights into the design solution, installation schematics, and final outcomes.
- Demonstration of how SPF standardisation improves system understanding and supports long-term sustainability goals.
Rinnai UK’s new division - Rinnai Applied, is also offering an opportunity to gain bursaries of £200 when those eligible successfully complete three specific CPDs.
The CPDs are on the following subjects:
- Seasonal Performance Factors (SPF) and Heat Pump Design
- Introduction to Water Neutrality
- Retrofitting Heat Pumps into the Leisure Sector through CCA & SPF Analysis
Rinnai continues to inform the UK market of system operating details that provide an accurate statement of system performance, while considering the effects on operational expenditure, economic investment, and environmental impact.
