Solar Water Heater

Evacuated-tube and flat-plate solar water heating systems that cut the electricity, LPG and diesel spent on hot water.

Product Overview

Solar Water Heater is part of Aumplus Power's renewable-energy product portfolio, developed around a simple objective: make clean energy practical, dependable and useful for real-world customers. The system uses roof-mounted collectors, either evacuated tube (ETC) or flat plate (FPC), to heat water through the day and store it hot in an insulated tank for use in the morning and evening. Rather than treating the product as an isolated piece of equipment, Aumplus approaches it as part of a complete energy solution that considers the customer's hot-water demand, roof space, water quality, climate and long-term objectives.

For customers evaluating Solar Water Heater, the most important consideration is not simply the equipment itself. A successful installation depends on sizing the tank to daily hot-water use, choosing the right collector type for the local water and climate, planning the roof layout and plumbing correctly, and ensuring the system can be operated and maintained effectively. Aumplus can support customers through this decision-making process so that the selected solution is aligned with the intended use.

Why This Solution Matters

Water heating is one of the largest recurring energy costs in homes, hostels, hotels and many businesses. Solar Water Heater addresses this by meeting most of that demand from the sun, reducing dependence on grid electricity, LPG or diesel-fired boilers and cutting the running cost of hot water. It can form part of a broader renewable-energy strategy where solar generation, storage, monitoring and energy management work together.

The value of Solar Water Heater is therefore best understood in terms of the outcome it enables. Depending on the project, that outcome may be a lower monthly energy bill, reliable hot water through the year with an electric or heat-pump backup for cloudy spells, reduced load on the building's electrical system, or progress against a site's decarbonisation targets.

Core Value Proposition

Designed around actual daily hot-water demand, sized in litres per day (LPD) rather than sold as a one-size unit.
ETC or FPC collectors selected for the site's water hardness, freezing risk and available roof area.
Pressurised and non-pressurised configurations to match the building's plumbing and pressure requirements.
Can be evaluated as part of an integrated renewable-energy solution rather than as a standalone purchase.
Optional electric or heat-pump backup so hot water is available on overcast days and through winter mornings.

Who Can Benefit

Solar Water Heater can be relevant to households, apartments, hotels, resorts, hostels, hospitals, guest houses, canteens, dairies and industrial units that need process hot water. The correct solution depends on factors such as the number of users and peak demand time, roof orientation and shading, incoming water quality and pressure, ambient winter temperatures, and the customer's backup and budget requirements.

Typical Applications

Homes & Apartments
Hotels, Resorts & Hostels
Hospitals & Guest Houses
Canteens, Dairies & Industrial Process Hot Water

How Aumplus Approaches the Project

Aumplus begins with the application rather than forcing every customer into a standardised configuration. For Solar Water Heater, the first step is establishing daily hot-water demand, the times of peak use, the available roof area and orientation, and the quality and pressure of the incoming water supply. This creates the basis for sizing the system and choosing between ETC and FPC collectors.

The next stage is assessment and planning: roof structural and shading assessment, tank and collector sizing, selection of pressurised or non-pressurised configuration, backup heating requirement, and the plumbing and insulation route from roof to point of use. Where the system forms part of a larger solar project, these considerations are integrated with the overall building services plan.

Implementation Considerations

Roof area, orientation, tilt and shading over the collector field.
Daily hot-water demand and the timing of peak draw-off.
Incoming water hardness and sediment, a key factor in choosing ETC vs FPC and in maintenance intervals.
Freezing risk on winter mornings and the need for anti-freeze protection or an FPC closed-loop system.
Water pressure requirements and whether a pressurised system or a pump is needed.
Insulated pipe routing to minimise heat loss between the tank and the taps.
Backup heating (electric element or heat pump) and its controls for cloudy periods.

Integration With Other Solutions

One of the strengths of a broader product portfolio is the ability to combine complementary solutions. Solar Water Heater can sit alongside a rooftop solar PV system, share monitoring, and use a PV-powered or heat-pump backup instead of a grid element. Aumplus can evaluate the complete building energy requirement and recommend how water heating, generation, storage and monitoring work together rather than looking at individual products in isolation.

Key Benefits

Cuts the electricity, LPG or diesel spent on water heating, lowering the monthly energy bill.
Long service life with low maintenance, mainly periodic descaling and collector cleaning.
Sized to the customer's real demand instead of a one-size-fits-all unit.
Can be paired with rooftop solar PV and shared monitoring as part of one energy system.
Backed by site assessment, correct sizing, installation and after-sales support from Aumplus.

Frequently Asked Questions

It supplies hot water for bathing, kitchens, laundry and process use in homes, hotels, hostels, hospitals, canteens and industry. The tank size (in LPD) is chosen from the daily hot-water demand and the number of users.

Evacuated tube collectors (ETC) are lower cost and perform well in cooler weather but can scale up in hard water. Flat plate collectors (FPC) are more robust for hard water and pressurised systems. Aumplus recommends the type based on your water quality, climate and pressure needs.

A well-sized system carries stored hot water overnight. For extended overcast spells or cold winter mornings, an electric or heat-pump backup can be added so hot water is always available.

A typical 100 LPD domestic system needs roughly 2 square metres of unshaded, south-facing roof. Maintenance is minimal: periodic collector cleaning and descaling, with intervals depending on local water hardness.

Yes. Solar Water Heater and solar PV can share the roof and a single monitoring view, and the backup heater can run from PV rather than the grid where the design allows.

Share your location, the number of users or your daily hot-water requirement, roof details and any water-quality information with Aumplus. The team can then size the system and prepare a commercial and technical proposal.
