Can a homeowner install a tankless water heater?
Installation. While it is possible to install your own tankless water heater, it’s not a job for inexperienced do-it-yourselfers. There are a number of different sizes and styles of tankless water heaters, including propane, natural gas and electric, along with single-room or whole-house sized models.
Is it hard to install a tankless water heater?
Tankless water heaters cost more than traditional tank water heaters; typically about twice the price for the unit alone, depending on what flow rate is needed. They’re also more difficult to install, as they have special venting requirements and often need larger gas lines because of the higher BTU rating.
Where should a tankless water heater be installed?
The ideal location for your water heater is inside the home. Most installations are small and unobtrusive so they will easily fit in a pantry, under the stairs, or under your sink. If you must place the water heater outside, make sure it’s safe from direct sunlight, rain, and insects.
Why is tankless water heater installation so expensive?
Installation is expensive because the unit needs a bigger gas supply than a conventional water heater does, and it needs to run its own exhaust flue to the exterior. Installation costs can vary widely, depending on the location of the flue and the gas supply. The unit itself costs between $800 and $1,000.
Do you need an electrician to install a tankless water heater?
Installation of a tankless water heater is NOT considered a “do-it-yourself” project. However, the installation of a Stiebel Eltron electric tankless water heater is relatively simple and can be done by any licenced plumber and electrician.
What is the downside of a tankless water heater?
The primary disadvantage of on demand or instant hot water heaters is the upfront cost. The smaller units that you often see won’t produce enough hot water to serve most households. They’ll only serve one faucet at a time—a problem if you want to shower while the dishwasher is running.
Can you run out of hot water with a tankless water heater?
With a tankless system, there isn’t a supply of hot water that can be depleted. Instead, the water heater heats up water as there is a demand for it. It will keep doing this as long as there is demand – and that means you won’t run out of hot water!
Is it worth switching to a tankless water heater?
The big advantage of tankless water heaters is that they use less energy since they only heat up water when you need it. You can save hundreds on your energy bill each year. Because they don’t waste power, you can also enjoy the fact that your home will be more sustainable and eco-friendly.
How much does a tankless water heater cost with installation?
The gas tankless water heater installation cost would be in the $1200 to $3000 range if switching from electric to gas. You do save about $250 because you do not need a tempering valve installed with a gas tankless water heater installation.
How high should a tankless water heater be installed?
The best place to install the unit is on the second floor. This is assuming that your laundry room is in the basement or first floor. Ensure that the heater or outlet water pipe doesn’t touch the combustible materials. Keep a distance of 24″ between the combustibles, the water heater, and the output hot water pipe.
What are the power requirements for a tankless water heater?
Unfortunately, the average electric tankless water heater needs at least 120 amps to operate and the average household’s total capacity is 200 amps. This means you will have to upgrade your electrical system to accommodate for the larger load demand, which could cost you up to $1,500.
How do I know what size tankless water heater I need?
How to Select the Right Size Tankless Water Heater
- Determine the maximum number of devices you want to run and their total flow rate. Then, add up their flow rates (gallons per minute).
- Determine required temperature rise.
- Sizing Example: An average shower will be between 104–106° and uses 2.6 gallons of water.
What is the average lifespan of a tankless water heater?
Most tankless water heaters have a life expectancy of more than 20 years. They also have easily replaceable parts that extend their life by many more years. In contrast, storage water heaters last 10–15 years.
How long does it take to install a tankless water heater?
