Tankless Water Heaters


This site is dedicated to reviewing and finding the best tankless water heaters that are available. It’s a one stop tankless water heater review site that does the homework for you, so you don’t have to pour through specs and compare features and benefits of all the tankless water heaters on the market. Tankless water heaters are phenomenal hot water systems that save space, are energy efficient, and save you time and money.

Tankless water heaters, also known as on demand water heaters, provide instant hot water, but only when you need it. You don’t have to pay to heat and store an extra 40 or 50 gallons of hot water just to take a hot shower that stays hot the whole time you are in it while the dishwasher is running. This efficiency and the new technology saves space and cost. Traditional water heaters heat and store excess hot water that costs you money. Think about it. Do you crank the heat up when you leave your home for a few days? No. Because it wastes money to heat a space that doesn’t need it until you need it to be warm when you are in it. Conventional water heaters do just that, they pre-heat water so you can have it when you want it, but they waste energy doing so. Tankless water heaters only heat the water when you need it.

By heating the water without the use of a storage tank, you avoid standby heat loss and therefore excess energy waste. Also, you won’t wait for a storage tank to fill up with enough hot water to use ever again, just turn on the tap and you have an instant supply of hot water. All units are different though, most tankless water heaters provide 2 – 5 gallons of hot water per minute.

  • ? Electric – In this type of system, an electric element heats the water.
  • ? Gas – In this type of system, a gas burner heats the water. Gas Tankless Water Heaters create higher flow rates than electric systems.

Both systems have there merits, but when researching tankless water systems, you’ll find some units and brands more effective and energy efficient, therefore cost friendly, than others. Most tankless water heaters deliver an instant supply of hot water, but some are easier to use and provide larger supllies of hot water than others. This review site will help you determine what unit best serves your purpose.
