Temperature is also another factor, when a hot water system is returning cooler water it means the demand is high. This means that the circulation speed needs to increase but also the hot water services providing the water to the ring main also need to increase intheir productivity, all these variables are programable with the right technology implemented. In a set-up such as this you will find a large commercial style of hot water arrangement manufactured by Rinnai or Rheem.

In South Australia there are a few common brands of pumps which our service technicians deal with on a daily basis. Brands such as Grundfos, Kwikflo, Javelin, Ultraflow, Davey, Vada, Wilo, Taco, Hyjet, DAB and Bianco are all common to the Adelaide pump market. We carry replacement parts and models to ensure your never without a properly functioning pump for any longer then required. Each manufacturer provides a range of sizes and speeds dependant on the pumps intended purpose. Majority of these pumps are powered via 3 pin plug which gets plugged into a 10-amp power point.

A good installation performed by a qualified pump agent will also have two isolation valves installed, one on the incoming side and the other on the outgoing side. These valves allow for quick changed overs without having to drain the entire ring main prior to commencing any work. In some elaborate set ups, there will be twin circulating pumps.

These pumps are not under the same demand as a typical pump where it is required to push a liquid at rapid speeds at a certain height gain. A circulating pump plays the role of ensuring the liquid inside the pipes keeps moving at constant pace to ensure even distribution of the fluid inside the plumbing pipe work installed and only overcome the friction inside the pipes as the liquid is moved around.

As technology has evolved so has the distribution of fluids. Today many of our pump installations a very complex. The ability to program a pump has been a huge development within the industry itself. Our commercial clients know when their peak periods of demand will be and with this knowledge, we are able to ensure the circulating pumps are working at full flow.

Circulating pumps are typically used to move hot or warm water around a building (aged care facility, hotel, food processing plants and large houses), circulate the water through a solar hot water system and its panels, glycol through pre-heating systems or under floors (hydronic heating) in Adelaide and the Adelaide Hills.
