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.
How much does it cost to replace a hot water heater with a tankless?
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.
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.
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.

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.
Are tankless water heaters hard to install?
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.
How often should you flush your tankless water heater?
