      Hayward is Horrible!!

      A long read, but kind of a long story. Our pool was finished in July 2024. We chose to have it heated and the pool builder installed a Hayward H150FD heater. The heater worked until we shut the pool down for winter in Oct 2024. It was fired back up again in May 2025 but stopped working by June 2025. It worked for about 5 months total and never worked again. The local plumbing/pipefitter company tried to get it working many times, purchasing and installing different parts, nothing worked. Hayward was contacted throughout this process, but all contact was only with an AI agent, humans don't work in the customer service department apparently. Hayward eventually denied warranty for the heater in July 2026 (a year later), with the AI agent saying basically that is not their problem. I purchased a new version of the same heater in Aug 2026, another brand of heater was preferred but would not have fit the existing hookups. The plumber came to install it and could not get the brand new Hayward heater working after several attempts. Eventually the plumber was finally able to talk with a real human Hayward technician while here on-site. Turns out the new heater was missing a fuse on the circuit board, it came that way from the factory. The other necessary fuses were installed, so the display worked and could be programmed, but the burners would not fire up without the missing fuse. Unbelievable lack of quality control! Hayward is absolutely horrible to work with and the products are total crap. If I could give a negative 5 star rating I would.

      We recently bought a pool heater. We’ve purchased other products from Pool Products Canada and have never been disappointed. Customer service is great. Dustin has been excellent to work with. He’s very knowledgeable and helpful! I would definitely purchase from them again in the future.

      I was aprehensive about buying on line, though the service was incredible. Every question I asked via email was answered in a timely manner and I look forward to installation in the spring. I am pleased to know that I have the supplier's support if any issues arise
