Our goal is to help businesses reduce water-heating energy consumption, improve system efficiency and maintain a dependable supply of hot water.

Commercial solar water heating

Solar water heating for commercial properties

Solar water heating can be an effective solution for commercial properties that consume significant amounts of hot water. By using energy from the sun, these systems can reduce the amount of electricity required to heat water.

GreaseFlow Solar assesses each property individually to determine the most appropriate system configuration, taking into account hot water demand, available roof space, existing plumbing, storage capacity and the property's energy requirements.

We design our recommendations around the needs of the building rather than applying a one-size-fits-all solution.

Commercial heat pumps

Commercial heat pump installations

Commercial heat pumps offer an energy-efficient alternative to conventional electric water heating. They extract heat from the surrounding air and transfer it to the water, generally using less electricity than conventional electric resistance heating for the same amount of heat delivered.

The appropriate system capacity depends on factors such as peak hot water demand, daily consumption, storage requirements, recovery time and the available electrical supply.

Suitable applications

  • Hotels and guesthouses
  • Apartment blocks and residential complexes
  • Schools and educational facilities
  • Healthcare facilities
  • Gyms and sports facilities
  • Restaurants and commercial kitchens
  • Staff accommodation and other high-demand properties

Large-scale installations

Large-scale hot water installations

Every commercial property has different hot water requirements. A small guesthouse, for example, will have different demands from a large apartment complex or hotel.

GreaseFlow Solar undertakes assessments to establish the property's hot water consumption patterns and identify the most practical installation approach.

Depending on the project, a suitable solution may include:

Multiple solar water heating collectors. Sized to the property's demand and roof layout.
High-capacity hot water storage tanks. Configured for peak demand and recovery time.
Commercial heat pump systems. For efficient heating where solar alone isn't sufficient.
Integrated solar and heat pump solutions. Combined for efficiency and reliability.
Additional storage for peak demand. Sized to real consumption patterns.
Upgrades to existing hot water infrastructure. Retain usable components where suitable.

Our approach is to recommend a system that balances performance, energy efficiency, reliability and long-term operating costs.

System upgrades

Upgrading existing commercial hot water systems

Replacing an entire hot water installation is not always necessary. In some cases, an existing system can be upgraded to improve its performance and reduce electricity consumption.

GreaseFlow Solar can inspect your current installation and identify opportunities for improvement. Depending on the condition and configuration of the system, possible solutions may include converting a conventional electric geyser installation to a solar-assisted system, installing a suitable heat pump, increasing storage capacity, or improving system controls and insulation.

We assess each installation before recommending an upgrade so that the proposed solution is appropriate for the property's needs.

Not sure whether to upgrade or replace? We'll assess your existing system and compare both options.

Commercial maintenance

Commercial solar and heat pump maintenance

Regular maintenance is essential for keeping commercial hot water systems operating efficiently and helping to prevent unexpected breakdowns. GreaseFlow Solar offers inspection, servicing, repairs and preventative maintenance for suitable commercial solar water heating and heat pump installations.

Our maintenance services may include:

  • Inspecting solar collectors and mounting structures.
  • Checking pipework, insulation and visible connections.
  • Inspecting valves and safety components.
  • Checking heat pump operation and controls.
  • Assessing water circulation and system performance.
  • Inspecting storage tanks and associated components.
  • Identifying leaks, corrosion and signs of wear.
  • Recommending repairs and component replacements where necessary.

Maintenance requirements and service intervals depend on the equipment, water conditions, operating environment and manufacturer's recommendations. A preventative maintenance programme can help property managers plan servicing, identify developing faults and reduce the risk of avoidable disruptions.

Common questions

Commercial solar & heat pump FAQs

What types of commercial properties do you work with?

We work with hotels, guesthouses, apartment blocks, residential complexes, schools, healthcare facilities, gyms, restaurants, staff accommodation and other commercial properties that consume significant amounts of hot water.

Can you upgrade an existing commercial hot water system instead of replacing it?

Often, yes. Depending on the condition and configuration of the existing system, we may be able to convert a conventional electric installation to solar-assisted hot water, add a heat pump, increase storage capacity, or improve controls and insulation. We assess the installation before recommending an upgrade.

How is a commercial system sized?

Commercial sizing considers peak hot water demand, daily consumption, storage requirements, recovery time, available roof space and the property's electrical supply. We assess consumption patterns before recommending a configuration.

Do you offer maintenance contracts for commercial systems?

Yes. We offer inspection, servicing, repairs and preventative maintenance for suitable commercial solar water heating and heat pump installations. Service intervals depend on the equipment, water conditions, operating environment and manufacturer's recommendations.

Do you work with property developers and contractors?
