commercial hot water systems

We are your Sydney commercial hot water specialists.

Commercial grade hot water systems are built to last. They operate at very high-efficiency rates running large volumes of hot water to suit any commercial application or the requirements of any sized residential or strata building. Both internal (inside) and external (outside) models are available for gas, electric, solar, warm water, heater exchangers and heat pumps systems.

Note: Commercial hot water systems may also be referred to as “industrial hot water systems and heaters”. 

Types of commercial hot water systems


Continuous Flow Commercial Hot Water Systems

With a commercial continuous flow hot water system, you virtually never run out of hot water. The latest commercial continuous gas hot water models feature electronic ignition, with no pilot light, operating on-demand only therefore not consuming gas when not in use.

For applications where high hot water flow rates are required for short periods, a continuous flow hot water systems can be coupled with a storage tank. This system is suitable where short periods of high hot water flow rate are required that can’t be achieved with just a continuous flow system. A thermostat in the hot water tank senses when it drops below a certain point and a primary pump is activated to heat up the water in the tank.

commercial solar hot water systems

Commercial Solar Hot Water Systems

Combine the energy of the sun with the high efficiency of gas or electric hot water heating. Typically, rooftop solar collectors are aligned to face the sun in order to maximise solar energy. Lower energy consumption, save on running costs and reduce your CO2 emissions by harnessing the power of solar energy to pre-heat your commercial gas and electric boosted hot water system. Several installation options are available depending upon the site requirements.

Commercial Electric Hot Water Systems

Electric hot water systems offer quick recovery and are ideal for small businesses and large scale installations.  They come in a range of sizes to suit all applications – even very small spaces. The controls are easy to adjust. They can be installed singularly or in a “bank” where high demand hot water usage is needed. Models are available for indoor or outdoor installation.

Commercial Heat Pumps

Commercial-grade heat pumps deliver extremely high thermal efficiency. Heat pumps use technology to extract and intensify the warmth that is naturally in the air around us then uses that warmth to produce hot water. They don’t use solar collectors mounted on the roof like solar systems.

The heat pump consists of an insulated storage tank and a heating module. The heating module must be installed outdoors, but there are options to install the storage tank either outdoors with the heating module, or indoors separated from the heating module by up to 4 metres.

A heat pump works to heat water by transferring the intensified warmth from the air around it into the water, stored in the tank, via a heat exchange system that works in a similar way to an air conditioner.

When emptied, it takes time to reheat to have you back in hot water. Heat pumps draw less electricity than a traditional electric storage water heater, and in doing so, are more energy efficient. They do take longer to heat water, so consider a larger tank capacity to ensure you have enough hot water when you need it.
