An important feature of any thermal store is that hot water can be supplied directly from the mains at conventional flow rates without the need for pressure relief safety valves or expansion vessels.
This is achieved by passing mains water through an internal plate heat exchanger. The outlet temperature of the domestic hot water is maintained by a thermostatic blending valve, which controls the water temperature, this allows the hot tap water to be delivered at full mains pressure, and is one of the primary benefits of installing a thermal store instead of a conventional hot water cylinder.
The PulsaCoil Stainless is available in sizes 150 | 180 | 210 LITRES
PulsaCoil Stainless operation and maintenance
The new circular PulsaCoil Stainless series is a thermal storage cylinder made of highly corrosion-resistant stainless steel that is specifically made for use in flats. It provides mains pressure hot water using off-peak power.
The PulsaCoil Stainless is an open-vented thermal store that doesn’t need any discharge pipework because it doesn’t need a pressure and temperature relief valve. As a result, the Part G Building Regulations’ prohibition on connecting a discharge pipe from an unvented cylinder to a dirt stack is circumvented.
An extremely effective plate heat exchanger is used to produce household hot water. Mains cold water is instantly heated as it travels through the heat exchanger and is delivered to the taps when hot water is required. The risk of Legionella is fully eliminated by this method of producing hot water. The creative design aids in simplifying installation and ongoing maintenance for the installer.
Additional advantages of the PulsaCoil Stainless include the immersion elements’ permanent placement in the same primary water that never changes, which prevents scaling even in places with hard water. The cylinder can use the off-peak electrical supply, which keeps the householder’s operating expenses to a minimum.
Unlike unvented cylinders, Pulsacoil Stainless thermal reserves don’t need any annual maintenance.
