Walmart offers the Eccotemp Indoor Tankless Water Heater for $240. Opt for in-store pickup to drop the price to $160. (Amazon charges the same price, although it's currently on backorder.) That's tied with last week's mention and the lowest price we could find by $86. It features 1/2" NPT water fittings acrylic glass casing, child locking technology, and automatic temperature controls.
