Are you planning to buy and install a tankless water heater at your home? It is about time. These days when costs of energy is getting higher and there is an ongoing financial crisis, you should do all possible tasks to significantly save money. There are numerous types of tankless water heaters that are available in the market. before you head to any retailer to buy your unit, you should first decide if you are purchasing an electric powered or a gas-powered tankless water heater.

Electric powered tankless water heater is of course powered by electricity. Numerous and serial electric coils are integrated into the appliance to instantly facilitate water heating when needed. Many consumers prefer it because it is convenient and is not bulky. On the other hand, gas-powered tankless water heaters are using gas burners for heating. The burners are turned on and off whenever the user needs to. If you are planning to buy a gas-fired tankless water heater, there should be requirements you must first consider.

First, identify whether the tankless water heater of your choice is using propane or natural gas. It is imperative to check out the current gas line you use to make sure it would meet the requirement of the gas-fired tankless water heater model of your choice. Such requirements may exceed those by your current tank-style or conventional water heater.

Second, consider all the necessary venting requirements for the specific installation. There could be several other things you should keep in mind when buying gas venting accessories that are required for the installation of your gas-powered tankless water heater.

Third, prefer category 3 stainless steel as a vent for your gas powered tankless water heater. Take note that type B vent accessories are inacceptable for the appliance. Make sure you check local building codes and regulations for your specific needs.

Gas-powered tankless water heaters are usually offered with gas-venting kits. You should first evaluate specific requirements of the installation so you could be sure the appliance has the necessary gas vent accessories. A pre-made kit would be ideal. Measure the vent route to consider where any discharge would go through, whether through the ceiling or the wall. Also take note of necessary clearances and information about air combustion access. Buy the required gas vent pieces.

Take note that some gas-powered tankless water heaters are also requiring even a minimum electric connection. Always review installation requirements of the units.

Water heaters are becoming such a necessity these days. For those who are into new houses that don’t have them yet, tankless water heaters are good buys because of savings, reliability, and overall ease of use. There are two choices for tankless water heaters: gas-fired or electricity-driven.  

Whichever system you choose, the savings earned up and the return on investments on tankless water heaters are the same.

Venting requirements

First, there is need to identify which gas type have you got, natural gas or propane. You need to examine your current gas line to ensure meeting the requirements. (The requirements of your new gas-fired tankless water heater may exceed that of your present tank storage water heater.)

Be sure to buy Category III stainless steel venting for your gas-fired tankless water heater. Check the local building code to ensure that your specific needs are met.

Disregard venting “kits” from manufacturers. Make sure, however, to measure out your vent route, consider where the discharge will go through (a wall or a ceiling?), the necessary clearances, and the ample access to air for combustion.

Only then will you buy the right gas venting pieces.
Location, size and demand

Where will you need hot water? What unit do you need – one that heats a bathroom sink, an entire bathroom, and an entire house? How many fixtures need hot water? Which ones need larger amounts of water?

Flow rates are important because tankless water heaters will generate temperature rise based on the flow rate specified.

If you live in cold New York, your ambient incoming water is definitely colder than that of Florida. 

Applications

There are several specific applications for your tankless water heater. Here are a few examples.

* Single point application is one where one fixture will require an electric tankless water heater.

* Flow controlled range of water heaters are suited to serve two points, like two sinks in close proximity.

* Thermostatic tankless water heater boosts the temperature lost in long pipe runs, dishwashers and sanitation. Good for applications where precise temperature control is essential.

* Series Two units are for residential showers, entire bathrooms, smaller houses, condos, and apartments.

* Whole house units are designed to serve an entire house, apartment, condos, etc. where multiple points of use exist.  There are two models, Whole House Indoors and Whole House Outdoors.

Installation

Proper installation will depend on climate and local building code requirements. Do not scrimp and get yourself a qualified licensed plumbing and heating contractor to install your tankless water heater.

Watch as I drain and refill our 50 Gallon water heater. Always make certain that the power is off before draining an electric water heater because if you drain it with the power on you will ruin the elements.
A natural gas water heater is a different shutoff procedure probably covered in other videos.

The bottom cover was off in the video because thats where I made a tempurature adjustment.
I refer to the the Presure relief valve as a Thermal expansion valve by mistake. I was thinking thermal expansion tank for some reason.
