8 SERVICES SYSTEM DESIGN CHWS can offer a system design service for Clients, Contractors and end users. Initial consultations are on a free of charge basis to ascertain the level of support required. Our system design service is limited to the selection and specification of the hot water generation system. We do not design distribution pipework systems downstream of the hot water generators or involve ourselves in specification of sanitary ware. We can also offer a service on systems that require the use of renewable or high efficient technologies such as solar thermal, CHP and Heat Pumps. CONSULTANCY CHWS also offer a consultancy service for the design of hot water systems using gas fired continuous flow water heaters. We can also offer product training, systems applications training and Sales Training to individuals, sales teams or designers involved in the specification, design or sales of continuous flow hot water heaters and systems.
