This vertically-mounted instant water heater is made of rust-proof engineered polymer, making it super durable. Coupled with that is a sturdy 304L-grade branded quality stainless steel inner tank, and an ISI-marked heating element, both of which promise an amazingly long product life. To further ensure a smooth user experience, the V-Guard Vinsta Instant Water Heater can handle water pressure of up to 0.6 MPa. This means it can be installed in multistoried buildings or any other type of residence without any worry. View Detailed Description
