Some instant water heaters are easy to install and can be set up by myself, while others may require professional installation. I preferred a model that offered straightforward installation instructions, ensuring that I could get it up and running without any hassle. Safety Features Safety is paramount, especially when it comes to heating appliances. I looked for models with features like temperature control, automatic shut-off, and anti-scald protection. These features gave me peace of mind that my family would be safe while using the shower. Brand Reputation and Reviews Before making a final decision, I spent time researching different brands and reading customer reviews. I wanted to know about the experiences of others who had purchased the same models. Positive feedback and a solid reputation in the market helped me feel more confident in my choices. Warranty and Customer Support Lastly, I considered the warranty and customer support offered by the manufacturer. A solid warranty indicates that the brand stands behind its product.
