Boilermate problems

Hydraulic Externally very similar to the expansion tank flange heating systems. However, the appointment and service conditions have other, hence there are structural differences.
First, the mode of operation over the accumulator loaded. In normal operation, its frequency response ranging from 5 to 15 times per hour in a properly-chosen volume of the accumulator. If the volume is chosen correctly, this quantity can increase up to 20-30 times per hour. Of course such an operation requires a robust, resilient membrane that can withstand a large number of loads.

Secondly, hydraulic accumulators are used in household plumbing, so the material must be non-toxic and approved for use with clean drinking water.
Third, the water supply system in most cases comes from a well or wells. It is saturated with oxygen, which is released and accumulates in the membrane. Therefore, the large accumulator at the top of the diaphragm and the valve sleeve is to vent the air. The appearance of the accumulator presented earlier in Figure 5.

Fourth, the accumulators are usually placed on cold water line in the water system, so in terms of the temperature at which they are being more benign regime. Typically, the water temperature in the system can not exceed 30 ° C.

As Boilermate and indirect water heater systems, hydraulic accumulators are filled with water is not full. The volume of "issued" when using water accumulator is less than the useful volume of the expansion tank heating system.
