The The Hydronic Systems Design Guide set contains new publication Selection of Control Valves in Variable Flow Systems (BG 51/2014) and Energy Efficient Pumping Systems (BG 12/2011). You can save up to £30 when you buy these guides together. Both guides will assist with the design of energy efficient variable flow systems. View sample
Selection of Control Valves in Variable Flow Systems (BG 51/2014) has been produced to help designers avoid problems with the selection and application of control valves used in hydronic systems. Types of valve covered by the guide include two-port, three-port, four-port and pressure independent control valves. Proper sizing of control valves is vital to ensure:
Energy Efficient Pumping Systems (BG 12/2011) provides recommendations for building services designers on the design of energy efficient pumping systems. However it will be invaluable to a broader group including manufacturers, contractors and end-users who will benefit from being able to design, install, select and manage more efficient systems.
The guide recognises that the potential for pump energy savings is substantial. Europump (a pan European association of pump manufacturers) estimate that systems could be 30 to 50% more energy efficient by careful consideration of components, design and installation. Indeed our research has shown that a potential energy saving of 80% is achievable between the worst operating constant flow systems and the best designed variable flow systems.
