Description

Product Description
The Apollo APIHP-15 150L High Pressure Solar Geyser is an integrated solar water heating system designed for medium-sized households requiring reliable high-pressure hot water. The system combines the storage tank and evacuated tube collector into a single roof-mounted unit, simplifying installation while delivering efficient solar heating performance.

It operates using evacuated tube technology, which absorbs solar radiation and transfers heat efficiently into the water stored in the insulated tank. The system uses natural thermosiphon circulation, allowing hot water to rise into the tank without the need for pumps, ensuring silent and low-maintenance operation.

Designed for high-pressure domestic water systems, the unit is suitable for direct connection to standard household plumbing. It includes compatibility for electrical backup heating, ensuring hot water availability during low solar conditions. The system is built with durable materials to withstand harsh weather conditions and long-term outdoor exposure.
