The name Kuuma is of Finnish origin and translates into "HOT" – a fitting brand for a premium line of barbecue grills and marine water heaters. Kuuma Grills are constructed of durable, corrosion-resistant stainless steel and are designed for the demanding marine environment, but are also perfect for RVing, camping, tailgating and home grilling. Integrated folding legs enable easy grilling on any flat surface. Kuuma grills also feature stay-cool handles, latching lids and can be mounted to any Kuuma grill mount. Kuuma Water Heaters are constructed entirely of marine-quality aluminum to help prevent galvanic corrosion. All water heaters feature an aluminum heat exchanger and a TIG welded interior tank. Kuuma is the water heater of choice for many OEM's. Every single Kuuma water heater and grill is tested 100% prior to shipment to our customers. Kuuma's main production location is in Sriracha, Thailand with additional inspection and assembly being performed in Greensboro, North Carolina.
