Case Overview
Australian homes are getting smaller, and a growing share of buyers want a compact solar water heater. A local partner asked Millionsun to develop a small-volume thermosyphon system with a single flat plate collector, set up to work with a gas instantaneous heater as booster. The partner handled local approvals, and we supplied the product and the technical documentation to support them.

Client Requirements
For an Australian partner, the product has to fit local plumbing practice and local regulation as much as the roof.
- Compact size: a low-height tank and collector for small roofs and a tidy street appearance.
- Booster-ready plumbing: ports and valves arranged for a gas instantaneous heater.
- Compliance support: test data and component information, to support the partner’s approval process.
- Tile-friendly mounting: a frame suited to tiled roofs and strong summer sun.
Our Solution
We approached the system as a small, tidy package designed around the partner’s compliance process.
- Small-volume tank: insulated, pressure-rated tank in a compact size, with ports arranged for booster connection.
- Single flat plate collector: matched to the tank for steady performance.
- Low-profile tile frame: adjustable feet suited to roof tiles.
- Technical documentation: test data and component information, so the partner can carry out the approval process with local bodies.
- Booster fittings: pipe connections and valves matched to the gas heater the partner uses.
