FAQ
What is the purpose of the expansion tank on a tankless water heater?
When the water pressure in a plumbing system becomes too high, it can cause damage to various components, including valves in plumbing fixtures, joints in supply pipes, and even the water heater. To prevent this damage, an expansion tank is used. This tank allows the expanding water from the water heater to flow into it, effectively relieving the excess water pressure in the system. This helps to maintain the integrity of the plumbing system and prevent costly repairs.
What happens if you don’t install an expansion tank?
An expansion tank is an essential component of a plumbing system because it helps distribute pressure evenly and prevents strain, ultimately increasing the lifespan of the system. In addition to the expansion tank, another effective solution is the Thermal Expansion Relief Valve. This valve not only equalizes pressure but also effectively manages the thermal expansion of water. By relieving the load on your pipes, both the expansion tank and the relief valve help maintain the integrity and longevity of your plumbing system.
Does my water heater need an expansion vessel?
Expansion vessels are essential components of unvented hot water systems. They are necessary in all pressurized hot water systems to prevent damage to closed water system components caused by increases in pressure. By maintaining pressure levels, expansion vessels ensure the smooth operation and longevity of the system.
