Disadvantages of tankless gas water heaters

  • They’re hazardous – Gas water heaters emit nitrogen dioxide and carbon monoxide (CO) (NO2). Numerous people die from CO poisoning every year, and thousands are hospitalized. According to health experts, children living in homes with gas appliances have a 40% increased risk of asthma [9].
  • Gas prices are erratic and probably will increase — Natural price fluctuations might reach 100% in a year. Most analysts also anticipate price increases over the ensuing few decades. On the other side, electricity is probably going to get cheaper.
  • Unhealthy for the environment – Natural gas contributes to climate change by releasing CO2 and methane. In addition, NO2 emissions from gas appliances contribute to indoor and outdoor air pollution and poorer health. Therefore, a heat pump water heater, considered the most energy-efficient water heater currently available, is a much better choice for most homeowners.
