Yes. Tankless computers that heat water can be fire hazard.There is no combustible FV system on tankless, as you find mandated with ordinary tank-type heater. But same with your fireplace.If flammable vapors are drawn into tankless air intake or fireplace, the flame will ignite vapors and cause fire inside home.Always shut down tankless pilot light and burner when using WD40, lacquers, solvents, spray paint, gasoline, etc.Do not store flammables nearby.And do not store or use other chemicals nearby since trace amounts of many household chemicals such as bleach and pool cleaners, craft products, household cleaners, etc will enter burner and corrode parts inside tankless, severely shortening life of tankless burner and sensors.The internal parts on tankless are un-known fire hazard, because I have not read specific reports in news.However most companies today have absolutely locked down news stories that might affect their sales, so these incidents are no longer getting reported if they are happening. So if you voted republican or \'conservative\' in the elections, then you voted to protect companies rights to withhold vital safety issues from you until enough people get killed that someone says something without fear of losing a job. Because the rich need you to protect their right to fire you from your job so they can get more money from you. And somehow they got people to vote for this, under the guise of protecting your job. lolGene If you need further help, I’m available over the phone at
