Water heaters have evolved to something much more than just a big pot of water on a burner. The traditional atmospheric vent gas tank and electric tank heaters are still available but now you have choices.
But just how Green is Green? Some new tankless models may actually be less efficient than the old heater you currently have in your home.
Which is best for you? There is no one answer, much depends on the size of your home, the condition of your water, the condition and size of your plumbing supply system, if you have a drilled well or sand point, available floor space and the volume of combustible air available. New tankless heaters also need to factor the incoming water temperatures and pressures.
Do you have a manufactured or mobile home with a gas water heater that needs replacing? You'll probably need to purchase a direct vent water heater. The sale heaters at the home center stores are not designed for closed spaces and can be a hazard if used.
Making a wrong or uninformed choice can cost you! A phone call is free. Feel free to call if you have any questions.
