Summer months typically put a lot of pressure on water supply systems, presenting a number of challenges. Higher usage, reduced flow rates and occasional stopping of the water supply in some regions can create problems for households - ranging from insufficient shower pressure to the inability to water the garden or use the washing machine at certain times. In order to ensure simultaneous water supply and reliable pressure, pump manufacturer Wilo is bringing to the market a combination of the efficient Wilo-Isar BOOST5-E-2G pump and a 500-liter buffer tank.

The buffer reservoir is filled automatically from the water supply network via a float mechanism, providing a 500-liter reserve of water for domestic use. When the water supply is halted or there is a drop in pressure, the accumulated amount allows the household to continue using water, while the pump maintains the necessary pressure in the plumbing system. "The high-efficiency Wilo-Isar BOOST5-E-2G pump, equipped with an integrated frequency converter, maintains constant pressure at points of use. Frequency control allows for smooth adjustment of pump operation based on demand, contributing to both comfort and reduced electricity consumption," Wilo commented.

To ensure safe work regarding the system, safety measures have been implemented for work in dry and overflowing conditions, allowing for automatic function without requiring constant user input.
