Rinnai Applied Head of Design Sean Ehlen evaluates the importance of heat pump system congruity utilising Seasonal Performance Factors (SPF) as the expected performance. Advanced evaluations and verified methodologies are the preferred modes of measurement. A heat pump’s capabilities should be based on actual operating conditions and locations to yield accurate pictures of on-site performance: […]

Guy Cashmore – Technical Director at Kensa Heat Pumps – explores how to minimise the temperature difference and maximise CoP in a typical heating application in order to achieve optimal and efficient heat pump performance. Electric compressor-driven heat pumps using conventional refrigerants all have very similar characteristics when it comes to the question of how […]
