Solar Hot Water Systems: Are You Really Saving Money?

If there’s one thing we can all get behind, it’s the idea of saving on our energy bills. After all, what could be more appealing than living the same lifestyle with a smaller price tag?

And, hey, if we can save money while also living more sustainably and reducing our carbon footprint, so much the better, right? You may have heard that solar hot water systems can help you to make substantial savings. You might even have invested in one already. On the other hand, you may be looking into getting a solar hot water system but aren’t quite ready to pull the trigger just yet. You might want to investigate whether or not a solar hot water system really lives up to the bold claims.

So, do solar hot water systems really save you money? Or is it all a clever marketing gimmick? We don’t blame frugal and cautious consumers for wanting to know a little more before parting with their hard-earned money. Let’s take a look at how a solar hot water system can save you money and how much you can expect to save.

How solar hot water systems work

In order to understand how this kind of system can save you money we need to take a closer look at how they work.

Just as a solar panel can be used to generate electricity, it can also be used to heat water with energy drawn from the sun. It’s a more efficient way to heat your water than by converting solar energy into electricity which is then transferred into heat energy.

There are two types of solar hot water systems:

  • Flat Plate Collectors– Used with a roof mounted tank
  • Evacuated Tubes– With a standalone tank below

Which system is best for you depends on your home’s setup and location. Evacuated tubes are more appropriate for homes which are prone to frost in the colder months. However, the energy benefits are much the same, with evacuated tubes being slightly more efficient as they don’t require direct sunlight and can even work well in high humidity.

How Flat Plate Collectors work

Copper pipes run through the glass- covered collector, usually connecting to a water storage tank on the roof. The sun heats the copper pipes and the heated water within is then thermo-siphoned out of the storage tank.

How Evacuated Tubes work

Two glass tubes fused together at the top and bottom. The space between the two tubes is evacuated to create a vacuum. A copper heat pipe runs through the centre of the tube to meet a common manifold. That then connects to a slow flow circulation pump. This pumps water to a storage tank below, heating the water throughout the day. Because the standalone tank is so well insulated, hot water can be used at night or even the next day.

What’s more, if the water in the tank drops below a certain temperature, an electric pump distributes it back to the pipes to be reheated. Check out this post to see more about how evacuated tubes work.

But, what about the days when there’s no sunlight?

Don’t worry, you won’t have to bathe in tepid water on winter days when the sun isn’t out. Most systems work in tandem with either a gas or electric booster which supplements the solar hot water system when there’s insufficient energy from the sun.

So, how much could you save?

As you can see, both methods are very efficient and sustainable ways to heat your water… But can they really save you that much?

The short answer is, yes. Yes they can!

In fact, according to the Department of Environment and Climate Change NSW, a solar hot water system can save you up to 75% on your water heating costs when compared to electric storage heaters or gas boilers.

According to Sustainability Victoria, a home with 3-4 people using heating roughly 200l of water an electric storage heater will spend $1,337 a year on peak tariff or $859 off peak. When using an electric boosted solar hot water system, however, this figure drops to just $293 (off peak).

Rebates and subsidies

Of course, aside from the ongoing savings you can make on your energy bills, the government’s green incentives can see you get a substantial portion of your installation costs back via rebates and subsidies under the Federal Government under the Renewable Energy (Electricity) Act 2000.

As you can see, there are many environmental and cost advantages to solar hot water systems.

Solar Hot Water Repairs: 4 Times They Went Horribly Wrong!

Ask anyone who’s had a solar hot water system installed and they’ll tell you that they’ve never looked back. After all, it’s by far the most cost-efficient way to heat your water, saving you up to 75% on your water heating costs.

What’s more, generous federal incentives mean that you can get installation subsidies and enjoy years of low cost hot water… All while getting the warm fuzzy glow inside that comes from knowing that you’re doing good for the planet.

Yet, while solar hot water systems are state of the art and easy to maintain, as with any form of technology it has its horror stories. From cowboy installers to have-a-go heroes attempting their own repairs, there have been times when solar hot water systems have gone horribly, horribly wrong.

Let’s take a look at 4 particularly unfortunate solar hot water fails…

When naive consumer meets unrealistic claims

Let’s begin with a story from the USA. A customer had a contractor install a solar water heating system with a heating coil that connected to his HVAC system. For this he paid the princely sum of $18,000 USD ($25961 AUD). The contractor claimed that this system would heat his water while supplementing the heating load for his HVAC in winter. The system consisted of an 80-gallon storage tank with 2 solar collectors mounted on a steep, west-facing roof.

However, the system was neither heating his water nor reducing his energy bills.

Oh dear.

But when we think about it, it becomes clear that neither the customer nor the contractor knew what to expect from this installation.

A steeply-angled, west-facing hot water system will only produce at most around 80% of what would be produced by a south-facing hot water system. Plus, because it gets fewer hours of sunlight in the winter months, that customer can expect a lot of cold baths in winter. Plus, the angle of incidence is poor so what little sun did hit the panels would mainly glance off in the winter.

The customer responded in the most American way possible… He sued the contractor.

Lesson Learned: Know your expectations and do a little homework. Plus, there’s no such thing as doing too much due diligence on your contractor.

The customer who almost made a terrible, terrible mistake

We live in the “big box” era. Many cost-conscious consumers will instinctively search for the lowest priced version of what they’re looking for in a “big box” store or online. And while this might be fine for a Playstation 4 or even a laptop… It’s not the safest bet for a flat plate solar collector. Heaven knows where the customer found his solar collector but when he removed it from its packaging he found that there was no mounting system. At all. How did he expect to attach it to his roof? Glue it on?!?

Lesson Learned: Resist the temptation to look for solar hot water systems online and leave installation to the professionals.

The customer who cut his repair costs in all the wrong places

When something goes awry with your solar hot water system, you want it back up and running again as soon as possible. But in your zeal to get your solar hot water system back on its proverbial feet, don’t cut corners in ways which could come back to bite you.

One customer thought that he could save money on repairs by buying his own water pump on eBay and getting a contractor to install it. However, a substandard unbranded electrical pump can create more problems than it solves. In this instance, the pump limped along for a couple of weeks before dying again.

Lesson Learned: Always consult with your installing contractor before replacing parts… And be mindful of where you source them from.

Beware the dangers of self-diagnosis!

Speaking of electrical pumps; one customer, upon noticing that he wasn’t getting as much hot water as he should be, decided to perform a self-diagnosis. He diagnosed / assumed the heat pump to be at fault because that was the only visible component. So he replaced it… Only to be met with the exact same problem.

The trouble is that there are a number of less visible links in the chain which could lead to issues that are easily mis-diagnosed as heat pump issues. Floating sediment can impede thermal transference coefficients. Conductor-to-water couplings can be damaged or misaligned and collector panels can become insecure in their mountings.

Lesson Learned: Save yourself the potentially expensive guesswork. Always use a qualified technician for your repairs.
