Isotemp’s new line of SPA water heaters are a cost-effective way to upgrade to the sensuous pleasures of hot and cold running water. Inside, they’re identical to the company’s Slim and Basic water heaters, but instead of the 304 stainless steel outer jacket of the other ranges, the SPA heaters have a tough polypropylene casing surrounding the polyurethane foam insulation. They come with a 115v heating element that’s isolated from the other metals in the tank to avoid galvanic corrosion, and are available in five sizes ranging from 15 liters to 40 liters. $TBA; indelwebastomarine.com
