First read as much info on water heaters before going anywhere. You do not need to become a tankless expert but try to at least get your feet wet on the subject. If you do not take the time to do this you can make a bad purchasing decision. Your goal is to find the best tankless water heater for you and your home. The more knowledge you have the better your decision will be. This is a investment and you need to take extra care in the selection process.
There are several different review sites and the number is growing daily. My site alone grows every day and I am trying to make it the best site for all your tankless questions. It has some good articles that will help you learn a lot and show you different brands, models and how to choose the right system.
Cost of Operation
The price that it takes to operate a tankless unit is a great deal less than with a regular tank type heater. Everyone needs to keep this in mind when making their purchasing decision. Even though they cost on average 3x’s more than the traditional water heaters in about 3 years they will have paid for their selves. If you would like to save even more then make sure you search for a unit with a high energy factor. The units with the highest energy factor also quialifies for the 2009 tax credit. Energy Star is also approving certain models starting in Spring 2009. Look for this label coming soon. A high energy factor of 0.8-2 would mean that model is energy efficient. This in turns means less cost and energy waste for you.
The traditional and therefore oldest hot water heater model in the United States is the tank type water heater. You can buy these for as low as $200. The tankless units will vary in prices starting at about $100 for point of use systems, $500 for electric tankless and starting at about $800 for the gas or propane models. You will spend more with a tankless and the cost will be greater the more energy efficient it is but in the long run you will save on energy and the units will pay for their selves on average of about 3 years. The tankless systems will also out last the tank type heaters. Traditional heaters last on average about 10 years and the tankless lasts around 30.
The main reason traditional water heaters cost more in energy is because of standby loss. The tanks are always filled with water that is constantly reheated to keep at the desired temperature so it is ready when you turn on the tap. This results in hot water just sitting around in the tank even while you are sleeping. The tankless completely eliminates this issue by only producing hot water on demand.
You may not be able to afford a whole house tankless water heater at this time but you can shave off a few dollars on your utility bill a month with a point of use unit. These usually range from $150-$300 depending on gallon per miniute usage. For example, a Bosch GL2.5 will give you 2.5 gallons of hot water a miniute. This is perfect for under your counter to supply hot water to your sink that is farthest away from your tank. These will help you conserve energy and provide you with much needed hot water.
Finding the right heater for your needs will be a little work but the key is never pick a heater based on price alone. Thank you for reading and good luck!
