Ariston Solar Water Heater 150 ltr

DXB Solutions LLC supplies Ariston 150 litre solar water heaters in UAE for villas, residential properties and suitable commercial hot-water applications. The 150 L capacity provides a compact solar hot-water solution where the required daily hot-water demand matches the system capacity.
For the current Middle East range, Ariston lists the KAIROS THERMO GR-2 150-1, a 150 L natural-circulation indirect solar system for domestic hot-water production.

Ariston 150 Litre Solar Water Heater

The Ariston KAIROS THERMO GR-2 150-1 combines a 150-litre storage tank with a solar collector to use solar energy for domestic hot-water production.

The system operates through natural circulation (thermosiphon). As the solar collector heats the fluid, natural temperature and density differences create circulation through the solar circuit without requiring a conventional circulation pump for this process.

This makes the system suitable for rooftop solar-water-heating installations where site conditions and hot-water demand are appropriate.

Flat Plate Solar Collector

The GR-2 system uses a flat-plate solar collector with a selectively treated absorber surface. Ariston specifies 95% absorption for the GR-2 collector, along with tempered collector glass and copper absorber tubing.

Solar radiation is absorbed by the collector and transferred through the solar circuit to support domestic hot-water production.

Natural Circulation Solar Water Heater

The Ariston GR-2 is an indirect natural-circulation solar system. Ariston identifies the system as designed for domestic hot-water production and available in single- or double-collector configurations depending on capacity.

Natural circulation can simplify the solar side of the system because circulation occurs through thermosiphon action rather than a conventional solar circulation pump.

Ariston 150 Litre Solar Water Heater for Villas

A 150 L Ariston solar water heater can be considered for villas and residential applications with moderate hot-water requirements.

However, I would avoid putting statements such as “150 L is suitable for 3–4 people” as a guaranteed sizing rule on your product page. Actual hot-water demand varies considerably with shower usage, incoming water temperature, fixtures, weather and backup-heating arrangements.

Energy-Efficient Hot Water

Solar water heating uses renewable solar energy to contribute to domestic hot-water production and can reduce dependence on conventional electrical heating when system conditions are suitable.

Ariston describes its solar-water-heater range as an energy-efficient alternative to traditional electric storage water heating.

Actual energy savings depend on solar availability, hot-water demand, installation, system sizing and backup-heating usage.

Ariston Solar Water Heater Installation

Correct installation is important for solar-water-heater performance and service life.

Installation considerations include roof orientation, collector positioning, structural support, piping insulation, safety components, hot-water demand and accessibility for future maintenance.

The GR2 150-1 is listed by Ariston for ground or flat-roof installation.

Ariston 150 Litre Solar Water Heater Maintenance

Periodic inspection helps maintain the performance of the solar water heating system.

Depending on the system and site conditions, maintenance can include checking the collector, tank, piping, insulation, valves, connections and solar circuit according to the manufacturer’s requirements.
