Tank in Tank with Two Heat Exchangers

With two heat exchangers, the Tank in Tank becomes the hub of an installation with several heat sources. One coil can take the solar collectors and the other a second source with its own circuit, such as a heat pump or a second collector field, while the boiler connects directly to the buffer tank.

It suits houses with a biomass boiler and solar collectors, holiday homes that want a backup, and commercial premises. Connecting several sources calls for well-designed controls; our technician can help you set them up.
