Bosch Hot Water Systems

Bosch pioneered continuous flow water heating in the late 1800s, and have remained at the forefront of water heating technology ever since.

To this day, Bosch’s water heating systems are still market leaders. Bosch has been pushing the envelope when it comes to efficiency for centuries.

But they don’t just provide their users with significant savings on running costs – using less energy means less damage is done to the environment, making Bosch hot water systems an eco-friendly choice.

Electric Storage Unit Hot Water Systems

The most commonly used electric water heater, Electric Storage Hot Water Systems use a large insulated storage tank that holds hot water until it’s needed. Water is held in the tank and elements keep it heated, when turned on, so that it is ready when the tap is turned.

Generally speaking, a gas water heater will be more expensive to buy than an electric model. It will cost less to operate initially though, because gas is cheaper overall per unit than electricity. This is balanced by the fact that electric heaters are more efficient and so cheaper to run. This means that long term electric storage heaters work out more economical.

Bosch Tronic 1000T

The Bosch Tronic is one of the most reliable and economical electric storage heaters on the market. Sizes from 80L to 400L are available.

Continuous Flow Hot Water Systems

The continuous flow design is an instant gas hot water system, also known as ‘tankless’, ‘instantaneous’ and ‘on-demand’ hot water systems. You are guaranteed hot water whenever you open the tap.  

Bosch pioneered the use of continuous flow water systems centuries ago, and remain at the forefront of tankless water heating systems to this day. 

A continuous flow water system is one which heats the water as it moves through the system, removing the need for a tank. Heat instead is applied to the copper pipes the water travels through on its way to the tap. A sensor lets the unit know when to start heating as soon as the tap is turned on, and then stops heating when the tap is turned off, meaning you only use the energy you need.

Continuous flow heaters provide instantaneous hot water when the tap is turned on, but do not waste energy heating water otherwise. They are among the most efficient domestic water heaters available. As an added bonus, they produce less greenhouse gas (CO2) than electric storage systems.

Bosch OptiFlow Range

The Bosch Optiflow range is designed to constantly adapt to Australia’s demanding climate. Combined with all the above advantages of continuous flow water heating systems, and built to be able to cope with the unique demands Australia places on it, the Opti Flow delivers consistent and instant hot water whatever the weather. 

Bosch Mechanical Range 

Bosch HydroPower

Another pioneering new hot water system, the Hydropower is a whole new form of  ignition from Bosch. The Hydropower removes any need for batteries, standing pilot lights or external power points, driving down the use of energy, and saving you money.

Bosch Standing Pilot

The Bosch standing pilot gas hot water heater is perfect for a continuous and instantaneous flow of hot water. Capable of providing from 10 to 16 litres per minute, this external range will suit most domestic applications.

Bosch Gas Hot Water System Troubleshooting

Tankless water heaters provide an endless supply of hot water and reduce energy costs. But many people, being more familiar with the traditional storage-based heaters, are put off as they are unsure how to recognise problems with them. Let alone how to then go about fixing them. 

Here we’ve included some tips to help you troubleshoot your Bosch water heater to see if the problem can be solved without calling a professional plumber. You should, however, get your hot water system serviced periodically. And remember, always disconnect the power supply to the water heater before removing the cover.

How To Reset Bosch Hot Water System

To reset your system, disconnect the power, remove the cover on the water heater. Then you’ll need to reset the high-temperature thermal cutout. It sounds complicated, but all you need to do is push the reset button in the center of the cutout, and then reconnect the power.

Hot Water Has Cut Out

Check your water supply. Connect the supply line to the blue inlet on the water heater. Reset the system, as described above. Leave the cover off and check the flow switch. This switch should activate when the hot water is turned on (if the switch does not activate you will need to call for service).

Turn the power selector screw to “Hi” with a screwdriver. Open the cover and turn the screw counterclockwise to loosen it. Push the screw from the “Lo” position to “Hi.” Turn the screw clockwise to tighten it. Check the water – if you still don’t have hot water, call for service. 

Problems With Water Flow

The first thing to do is to check the plumbing for blockages or restrictions. Assuming this is fine, open the service inlet valve – turn counterclockwise to open fully. 

Once this is open, turn the shutoff valve on the water supply line counterclockwise to open fully. If there is still no flow, call for service.

Water Temperature Fluctuates

Turn the shutoff and service inlet valves counterclockwise to turn on the water supply fully.

Then, shut off the inlet isolation valve on the water heater. 

Turn the hot water faucet on in a nearby sink: if there is a steady stream of water, the cold water is flowing into the hot water lines. You will need to call a plumber to repair this. 

If this is fine, remove the aerators on household faucets and remove sediment clogging the aerators. If there is still an issue, call Hot Water Brisbane for repairs.
