There are three basic thumb rules that can help your decision in buying a Tankless Water Heater thus making it an easy one. It is best to simply concentrate on and evaluate three reasons:
1. Type of fuel used.
2. Precise Location, Size of Unit and Demand.
3. Uses of the Tankless Water Heater.
Type of Fuel used
Once the definite decision to buy a Tankless Water Heater is made, the first important factor to is the type of fuel that will be used in the heater. The choice is between an Electric Tankless Water Heater or a Gas-Fired Tankless Water Heater. Each of them has their own sets of requirements that should be considered very thoroughly.

There are three aspects of electricity to consider when you decide to install an electric Tankless Water Heater: The input voltage to the unit, the starting and running current it draws and the circuit breakers. Retailers usually sell their units to allow voltage in 110V, 120V, 208V, 220V, 240V, and 277V.
Various units will draw different measures of current. What you need to make sure of is the electrical demands of the Tankless Water Heater can be met by the electrical system installed at your premises.
It would be advisable to have special circuits installed to support only the Tankless Water Heater. This is to make certain the circuits shore up the heater you intend installing. However, it would also be good to consult a qualified and licensed electrician to make sure you are on the right track. If you plan a heater that is gas-fired, then you need to consider the gas used and the venting needs:
First off, identify if the unit runs on propane or natural gas. The existing gas line has to be checked to ensure that it can meet the new needs after the Tankless Water Heater is installed. The new Tankless Water Heater may need much more that what your existing storage water heater would mandate.
While looking into your venting, ensure that only quality Category III stainless steel (UL1738 certified) is used. Also check local building codes. Many Tankless Water Heater manufacturers sell ready ‘venting kits’. You need to independently evaluate your requirement for your specific installation and arrange for the necessary gas-venting accessories. A ready kit may or may not meet your needs though. Take into consideration all the peripheral requirements and only then venture into the purchase of gas venting accessories. You must take note that some minimal electrical supply may be needed even for gas-fired heaters.
Precise Location, Size of Unit and Demand
It is now time to decide at
what precise point of the setting the hot water will be needed. Will it be required in only one sink in the bathroom or the entire bathroom? Will it be going into the entire house? You must identify each fixture that will run the hot water since each one will stipulate a unique requirement. You must also remember that Tankless Water Heaters produce a rise in temperature depending on the stipulation on the flow rate.
It is also important to calculate the surrounding incoming water temperature, which depends on your geographical location and weather. This should take care of the temperatures involved. But if you expect the demand for hot water will increase, you need to add together all the outlets and then calculate the temperature rise needed to meet your overall need.
Uses of the Tankless Water Heater A particular application may be originating in your mind. Consider the list of specific applications listed below for diverse available brands:
Single Point Application Here only one fixture needs the hot water flow from the Tankless Water Heater. Flow Controlled These are used to serve two outlet points placed close to each other.
Thermostatic This is a temperature enhancer for loss of heat while water passes through long pipes, dishwashers and sanitation. Thermostat units are excellent for use in places like schools and laboratories, where-in accurate temperature control is necessary.
Series Two Series Two units are suitable for use in residential showers, complete bathrooms, smaller houses, condos, summer cabins and apartments. They will also have room for industrial boosters and high flow rate purposes. Whole House Indoor Use/ Whole House Outdoor Use
These indoor/outdoor units are intended to provide for an entire house, apartment, condo or cabin, which has many points of use.
