Location Of Boiler, Accumulator Tank And Laddomat®
When the boiler starts to fire up, Laddomat circulates the water internally in the boiler, so that it rapidly achieves its working temperature and can begin to heat the tank. Laddomat then pumps the hot water into the top of the accumulator tank slowly and under full control, so that separation remains optimum. In addition, Laddomat cools the boiler with pre-heated return water – hot water from the top of the boiler is diluted with a little cold water from the bottom of the tank.
These functions give the boiler so much better operating conditions that certain boiler manufacturers extend the guarantee on their boilers if the heating system contains a Laddomat. The reason for this is that the risk of corrosion in the bottom section of the boiler is drastically reduced when return water is pre-heated. Below you can see the operating phases of Laddomat.

| Startup. When the boiler starts up, the Laddomat pump also starts, most conveniently by using a flue thermostat. | Operation. The Laddomat charges the tank at so low a flow that separation is kept optimum. |

| Conclusion (Laddomat 11 and 21). When the tank is nearly fully charged, Laddomat cools down the boiler with maximum flow. When the boiler has burnt fully out the pump is stopped by the flue thermostat. | Self-circulation at the conclusion and self-circulation in the event of a power cut (Laddomat 21). The hot water that remains in the boiler continues to charge the tank because the water self-circulates. In the event of a power cut, Laddomat will automatically begin to charge the tank using self-circulation. |
