Benefits and Disadvantages of Using the Best Tankless Gas Water Heater
Tankless water heaters are becoming a more and more popular option as the years go by. They are compact and long-lasting while also helping you to save water. However, they also come with some disadvantages.
Here are the main benefits of tankless gas water heaters:
· You can use electricity or gas to power your heating unit.
· However, if you have been using electric water heaters until now, you probably noticed the drain in your wallet.
· That is the main reason why tankless gas water heaters with recirculating pumps gained popularity in the last few years – they are highly efficient.
· What is even better, you can choose between natural and propane gas, as most of the tankless gas water heaters with recirculating pumps we reviewed in this article support both.
· There is no need to wait; these water heaters will supply you with hot water at any time.
· Tankless gas water heaters with recirculating pumps are environment-friendly as well, as they spend less energy than the electric ones and they don’t produce any fume.
· You are not going to believe this, but gas tankless gas water heaters with recirculating pumps are recyclable as well!
· Additionally, these water heaters are space savers!
· There is no need to store water in a tank, as the unit produces hot water the second you turn the faucet on.
· If you care about the aesthetics, you will love gas tankless gas water heaters with recirculating pump for one more reason.

· You’ll probably need to upgrade your existing gas line prior to installing a tankless water heater.

· They might not work as efficiently in colder weather as they have a limited flow rate.
· While they come at various price ranges, tankless gas water heaters typically cost more than gas heaters with a tank.
What Is a Recirculation Pump for a Tankless Water Heater?
A recirculation pump, also known as a circulator pump, periodically circulates water from the pipes to the water heater to reheat them. You can use them to prevent the water in the line to cool down entirely. This way, the water will be hot at any time of the day – or precisely at the time, you set it to be.
Usually, people set up this system to circulate the water between the tankless heater and the fixture that is furthest from it.
· A recirculation system usually includes:
· A water heater and a pump, either joined or separated.
· A recirculation method, which can have two options: a dedicated return line or a bridge valve.
· Some way to control the pump when it runs out – usually, these pumps have a timer or an aquastat.
Why Recirculating Pump Matters?
The built-in recirculation pump eliminates a massive disadvantage that regular tankless water heaters have – which likely happens to be the only one they have.
The biggest complaint about tankless water heaters is that they take time to heat water. This is because, without the tank, the water doesn’t have a place to be stored in. However, with a recirculating pump, this is no longer an issue.
The truth is, tankless heaters warm up the water almost instantly. The problem comes when the water has to go to the fixture.
The cold water needs to run out from the line before it’s hot water’s turn.
With regular tankless water heaters, you’d need to install a recirculation pump. This usually includes installing a dedicated return line, as well. However, some water heaters come with a recirculating pump already installed. This means you’ll get your hot water immediately.
You can turn on a recirculating pump with one or several of these four options:
· Pushing a side button
· Using a motion detector
· Using a timer
· Using an app
Once you turn the pump on, the water becomes warm instantly. Also, now you no longer need to drain that water. It automatically goes back to the pump’s cold line.
Benefits Of Using The Best Tankless Gas Water Heater With Recirculating Pump
There are several reasons why you should opt for a tankless water heater with a pre-installed recirculating pump. These include:
· You’ll be saving water, so you’ll live a greener life
· You’ll save more energy, as well
· You’ll save money since you’ll spend less on expenses such as utility bills
· You’ll get an instant and endless amount of hot water
Of course, this doesn’t mean that these pumps don’t have their own downsides. The main one is that these gas water heaters are much more expensive compared to regular models.
