Thermal Stores have been tested in accordance with
HWA Thermal Store Specification
(Multifuel). Heat losses should not be directly compared with heat losses from unvented/vented
cylinders because the unvented/vented cylinders are tested at 65°C and the thermal store at
75°C so they are treated differently in SAP.
