Internal Hot Water Coil Thermal Stores

Direct Thermal Stores accept a heat input to the primary water usually from a wood burner or other open vented system. They are usually always also fitted with an electrical immersion heater as a back up.
Indirect Thermal Stores have the same function and design as a direct unit with the addition of an internal indirect coil. This is very useful when an additional heat source is available such as a solar thermal system.
