2. Technical Specifications
The standard models of the Flamco compact heat storage are supplied with PCM58 and these heat storage can be used in combination with any
heat source which can run at flow temperature greater than 65 °C. The discharge temperature from these standard compact heat storage models
will be between 52 and 55 °C.
The overall dimensions and weights of the compact heat storage models in the FlexTherm Eco range are listed in table 2.1 and their technical
specification is listed in table 2.2. The pressure loss characteristics of the compact heat storage are tabulated in tables 2.3a, 2.3b, 2.3c.
