Are solar water heaters worth it?

Definitely, a solar water heater is worth the investment.

In spite of upfront cost being relatively on the higher side, a solar water heater saves you a ton of money in the long run.

Unlike a tankless water heater that uses conventional fuels such as natural gas, electricity, a solar water heater runs on solar energy which is available in abundance and of course, FREE of cost.

The pros of a solar water heater overshadow the cons with a tangible margin so it’s worth investing in a solar heater.

Most of our clients who have been using a solar water heater for quite some time have found a 50 to 80 percent drop in their water heating bills.

Was I able to answer your question correctly?

What are the advantages of installing a solar water heater?

It’s of utter importance to know the various benefits that come along with a solar water heater.

Definitely, it’s gonna help you in making an informed buying decision.


Well, it’s quite obvious that the cost of the fuel would be zero as solar water heater uses solar energy as fuel which is available in abundance.

Most of us are aware of the fact that solar energy is a renewable source of energy and most importantly, it is environment-friendly too.


One of the main reasons why we recommend solar water heater @izzysmarthomeguide.com has to do a lot with its efficiency.

Most of the top-rated solar water heaters available on the market are capable of converting 80 percent of the radiation into heat energy which clearly depicts the level of efficiency these little beasts are up to.

Budget-Friendly Installation

Yes, you guessed it, RIGHT…

The installation process is quick, easy, and will not involve tons of money.

In fact, you’ll spend a lot less on the installation of a solar heater as compared to a PV panel.

In layman’s terms, the investment is one time and the benefits you can reap for years to come.

Compatible With Small And Compact Space

I agree that as compared to a tankless water heater, the space required for installing a solar heater is much more.

However, in case of scarcity of space, you can opt for a thermal panel, and trust me, it will do the trick for you.


One of the best things about a solar water heater is that it is environmentally friendly which means it will not produce any pollutants that can harm our mother planet.

In layman’s terms, it wouldn’t be wrong to say that there isn’t any greener energy than solar panels.

With zero emission, low carbon footprints, and no dependency on fuels, these little beasts are bound to deliver high performance without adversely affecting our planet.

Low Maintenance

The maintenance cost is almost zero.

In the name of maintenance what all a solar heater needs is regular cleaning to keep specks of dirt at bay.

The lack of presence of moving parts reduces the maintenance cost drastically.

With lower maintenance and a longer lifespan, the demand for these panels is bound to surge in the future for sure.

Are tankless water heaters worth it?

Of course, they are worth the investment.

As compared to a conventional water heater, the tankless counterparts are compact, durable, efficient, and long-lasting.

Our clients found a decrease in water heating bills up to 40 percent when they upgraded from a conventional heater to a tankless water heater.

A tankless water heater is mainly of two types, that is, a gas tankless water heater, and an electric tankless water heater.

The gas tankless water heaters are further bifurcated into propane tankless heaters and natural gas tankless heaters.

Almost all tankless water heaters use advanced technology that makes it possible to heat the water in real-time.

So, heat loss to the environment is NEGLIGIBLE.

Unlike a conventional water heater, you don’t have to store water in a tank.

The real-time heating mechanism makes it possible for a tankless water heater to deliver an endless supply of water.

What are the benefits of a tankless water heater?

Frankly speaking, a tankless water heater is packed with endless benefits making it one of the most sought-after products in the USA market.

Let’s have a quick look at some of the highly beneficial features of a tankless water heater.

Instant Hot Water

It is capable of providing up to an endless supply of hot water on demand, thanks to the heating mechanism and advanced technology that is used in the heater.

Once the cold water from the pipe is flushed out, you’ll start getting the hot water in your faucet, shower, etc.

Longer Lifespan

As compared to a conventional water heater which is meant to last roughly a decade, a tankless counterpart will last for two decades or even more in some cases.

The longer lifespan is yet another reason for its popularity.

Low Operating Cost

The operating cost especially for the electric variant of a tankless water heater is quite low.

In fact, an electric tankless water heater uses a very simple heating mechanism that doesn’t involve any complex steps so the maintenance is very low.

Suitable For Small And Compact Space

Unlike a conventional tankless water heater, the tankless counterparts don’t require much space for their installation.

They can be easily installed in small and compact spaces.

In fact, you can free the ground space by wall-mounting a tankless water heater which isn’t the case with a conventional heater as it comes with a tank and so requires huge space for installation.

As we all know, an electric tankless model doesn’t have a tank so the space requirement is very less.

No Standby Loss

Since a tankless water heater doesn’t store hot water so standby hot less is NEGLIGIBLE.

On the other hand, traditional water heaters have to heat the water repeatedly leading to increased fuel costs.

Wrapping Up | Tankless Water Heater Vs. Solar Water Heater

So, to conclude, both tankless water heaters and their solar counterpart are good as long as they not only suffice your needs but also falls well within your budget.

If you’re willing to pay more upfront then definitely solar water heater could be a great choice as it is packed with idiosyncratic features, and most importantly, uses a renewable source of energy which is available in abundance at NO EXTRA cost to you.

On the other hand, if you’re NOT in a position to invest a good lump sum upfront, then my advice would be to upgrade from a conventional heater to an electric tankless.

Time and again, we’ve reiterated the benefits of a tankless water heater and why it’s high time that one should upgrade from a conventional heater.

Thank you, once again for being with us till the end, and I’m beholden to you for the same.

That’s all, as of now :):)
