They’re known for selling high performing, highly efficient heaters with a generous warranty – some models even come with a lifetime warranty. Because of that, this is a brand in the premium price bracket but we think it still represents good value for money, because it’s an affordable option for an electric pool heater that will last as long as many more expensive alternatives.
