Who Installs A Tankless Water Heater?

Plumbers have traditionally been the ones to install water heaters. Electric tankless hot water heaters have help change that. Tankless models - the electric kind - have quick heating technology that require high amperage use. It takes a little more know-how, and many plumbers are not yet familiar with this technology.

In spite of this new technology, electric tankless hot water heaters are not that difficult to install; you can do it with average plumbing and electrical skills. To find out if you have the necessary handyman skills, get an installation manual from the manufacturer’s website and a good how-to book. Read up on what’s required for electrical and plumbing installation. You may decide you can do this yourself after reading through this literature.

The electrical model heater is much smaller than a regular hot water heater and lightweight enough to be a one-person job. The big question is whether your electrical panel has the capacity to take on an extra 80 or 120-amps that an electrical model tankless requires. Talk with someone at a home improvement center to get an experienced opinion. Or, if you have an electrician you’ve used before, he can give you the information without making a house call.

One of the things an electrician will tell you is the wire used for your old tank model heater is not adequate for your new heater. The installer’s manual will tell what’s required. In addition to new wire, you will need two or three 40-amp breakers, depending on the size unit you are planning to install. An electrician can also advise you on whether you electrical panel is adequate for the job.

Piping has gotten a lot easier for those not up on “sweating” pipes. Compression fittings make the whole process real simple. It’s just a matter of pushing pipes into the fittings for leak-proof connections

These are supplies that you can get at any home improvement store.

If you decide to do it yourself, there is information on manufacturer’s sites and other sources like http://www.installing-a-tankless-water-heater.com that can walk you through the steps once you’re sure you are up to code and ready to go.

Best Tankless Hot Water Heater - How It's Cost Effective

The rising cost of gasoline, food and just about everything else is starting to have an effect on pocketbooks. Some estimates put hot water at about 20 - 25 percent of home utility costs. So any savings here are significant. How big these savings are depends on several factors that, in turn, depend on you. If you are in the market for a hot water replacement consider that a tankless hot water heater may be the best choice.

What determines the best choice

1) Where you live plays a big part - Living in the northern half of the US means colder winters. this could mean that the temperature entering the house could be near 40 F degrees. To be useful for a shower it needs to be heated to about 110 F degrees. Ground water temperature is less extreme in warmer months. Any heater you choose will have to bridge that gap. This one factor in choosing the right heater.

2) Water use - How many faucets to you have running at one time? Using multiple outlets at the same time means more water heated on demand. You should make some estimates of this because it is a big factor in determining the best tankless hot water heater to fit your family’s needs. A bucket and a watch is about all it takes to find the gallons per minute flow rate that your tankless water heater will be required to generate.

3) The utility bill - Rates for natural gas and electricity vary throughout the US. In some regions the two are very competitive. Being able to compare could be significant in deciding whether to go gas or electric. Convert the kilowatt-hours and cubic feet of gas into thems to compare rates.

4) Getting the most from the system - Long pipe runs mean heat loss. It pays to insulate pipes wherever you can access them. The most effective hot water heating solution could be to have multiple heaters. In fact, mixing gas and electric could be the most economical answer.

Passively heating water before it reaches the tankless hot water heater is an excellent way to cut heating bills. If your current tank is in a warm part of the house, replacing it to an uninsulated tank so it can work to preheat water.

5) Installation - The size of tankless models - an electric is about the size of a PC - make them easy to handle. If your choice of the best tankless hot water heater turns out to be gas, then you should get several estimates from experienced technicians. These models require dedicated gas lines and a specific, high temperature venting. Adequate fresh air supply is important and a CO2 detector is recommended, especially for well-insulated homes.

Electric tankless hot water heaters are much easier to install. In fact, you may have the DIY skills to do it yourself. Check the power supply of your electrical panel to make sure it can handle the load of an electrical tankless model. Wiring to the old tank heater won’t work and it will take new breakers but beyond some simple plumbing it’s a job that can be finished in ca couple of hours.
