The Hotspot Titanium is manufactured with great care. It is supplied with a 20 years warranty against corrosion on the titanium inner tank, and a 2-year warranty on all other components. You can extend the warranty to 5 years by registering your Hotspot Titanium. The warranty period takes effect from the date on the invoice. All installations must include a filter system and the filter must be changed regularly as a warranty condition. Note: the product can be registered up to 3 months after the invoice date. Please contact us if you encounter problems during the registration.
