Plumbing schematics

Solartwin can be installed direct onto an existing vented hot water system. For mains pressure solar hot water we recommend use of vented thermal stores, which offer mains pressure hot water without the maintenance associated with pressurised hot water storage. In commercial applications we utilise thermal stores to preheat the mains water supply to primary heating source.

Thermal stores...
  • Minimise stored volumes
  • Are low maintenance
  • Avoid Legionella pumps (which use energy)
  • Allow installation of multiple heating sources
  • Are simple to install

    (Schematic 1 – standard vented direct)

    (Schematic 2a – thermal store indirect)

    (Schematic 2b – thermal store direct)

    (Schematic 3 – commercial preheat)
