No longer should you settle for the chunky, space-hogging, basement occupying water heater of the past.

In this tankless water heater review, you are introduced to ten of the best tankless water heaters that we recommend for your consideration. Depending on your home situation and water heating needs, you may find the right water heater that suits you.

Before we dive in, here are a few things you must consider when buying your tankless water heater.
As with all tankless water heaters that deliver hot water on demand, the flow rate is critical to their performance. The flow rate is the amount of water that the tankless water heater can heat up at any time. So, a low flow rate limits the amount of hot water you can enjoy from your unit. You can tell instantly whether your tankless water heater is suffering from a low flow rate when you step into the shower, and a blast of lukewarm or cold water hits you in those first seconds. For the best results, select a tankless water heater that can heat between 2 to 5 gallons (around 8 - 19 liters) of water per minute. This way you won't run out of hot water.
Choosing the best fuel type when considering the set up for your tankless water heater is a vital decision if you are concerned about costs and efficiency. Options typically considered are electricity, propane, and natural gas. The fuel you choose depends on your estimated annual expenses (can you afford this?) and whether the particular fuel option is available in your location. If all types of fuel are available in your area, you would need to consider the fuel cost and whether the tankless water heater you are considering will function efficiently on such fuel. Your best bet in this situation is to research your options carefully before making a final decision.
How efficiently your new tankless water heater will use energy is another consideration when choosing your water heater. Of course, saving on energy usage and cost is a crucial factor when you change from the traditional water heater to the tankless variety. Carefully compare the energy factor (EF) ratings of each brand or type of tankless water heater. Although at first the energy savings you experience with a new tankless water heater may be impressive, over time and as your family's hot water needs increase, your savings might not be so significant. That said, it is still a useful exercise to check on the heater's energy ratings when choosing the best tankless water heater for you.
If you live in warmer areas, expect better performance from the ECO 27. It heats twice as much water per minute! Enjoy longer showers, get the dishes and laundry done, and do other activities without running out of hot water. Set the temperature to what you desire with your digital temperature control - anywhere from 80°F (27°C) - 140°F (60°C). Another benefit of using the ECO 27 tankless water heater is the tremendous savings to your water heating cost. The sleek and compact ECO 27 tankless water heater also saves you precious floor space as well. Not to mention the advantage of the ECO 27's self-modulating technology that allows for incredible energy savings, as the heater uses only the amount of heat required. Goodbye traditional water heater!
