Who Can Install A Solar Water Heating System
All solar water heating systems must be installed by a qualified plumber who is experienced installing solar water heating.
The installer will also make sure that the system does not compromise the waterproofing of the roof.
You may also need an electrician to connect an electric booster system and timer. Alternatively, your plumber may be qualified to do this.
Comparing Costs And Determining Payback For A Solar Water Heating System
Now that we know the cost of conventional heating we have to estimate what that would be reduced to and subtract that to estimate the savings in fuel associated with a solar water heater. In the SEF determination, the power required to operate pumps and controls also considered.Annual Solar Energy Savings = Daily Hot Water Energy *-)
For example the natural gas savings consumption from a solar system with an SEF of 2.5 would then be
Annual Solar Energy Savings = *-)=174 therms/year
Prices for natural gas vary significantly by location and by month. In May 2021 the US average was $1.776/therm, a significant increase over earlier years. The average from 2011 to 2021 is about $1.50/therms and we will use that in our example. The associated Annual Solar Cost Savings would be:
* = $261/year
For and electric water heater with UEF=1.0 and electric price of $0.08/kWh the energy and cost savings per year would be:
Annual Solar Energy Savings = *-)= 2634 kWh/year
And the associated Annual Solar Cost Savings would be:
* = $274.46/year

But its solar PV that has exploded into the global electricity sector, thanks to manufacturing innovations and strong government support. Leveraging economies of scale, the price of solar PV panels has dropped by over an order of magnitude in the past decade. In California, additional boosts came from government-instituted solar feed-in tariffs, cheap financing plans and private-sector investments. And, in a major coup for the industry, California mandated solar PV on new residences up to three stories starting 2020.
On the other hand, Californias residential solar water heater industry finds itself in a vicious cycle of low consumer demand and high prices. As the CSI-T report notes, In contrast to conventional gas and electric water heaters, which are typically installed by plumbers, solar water heaters are installed by a range of firms and public entities. In other words, consumers must actively seek out solar water heaters by relying on nonstandard sales channels.
All told, the cost of the average solar water heater sold in California through the CSI-T program was US$7,400, compared to less than US$1,000 for a fossil fuel alternative. By contrast, a solar water heater in Israel can cost as little as US$700.
Rather than embracing the growing portfolio of technologies available to solve the carbon emissions problem, going all-in on one satisfies the very human need for magic bullets.
Its just the sizzling, sexy PV really captivates the audience, says Murray.

With An Electric Auxiliary Tank System:
You need to know or convert the unit cost of electricity by kilowatt-hour . The Average Electricity Rate in the U.S. was 10.42 cents per kilowatt-hour in 2021. Hawaii has the highest average electricity rate of 30.55 cents per kilowatt-hour. Louisiana has the lowest average electricity rate of 7.01cents per kilowatt-hour. With the UEF of 1.0 and an electricity price of $0.1042/kWh and example of Annual Water Heating Costs for electric water heater is:Annual Water Heating Cost = × 12.03 kWh/day ÷ SEF × = $457.54/year.This example shows electricity more expensive than natural gas which is very often the case.
The Disadvantages Of Traditional Hot Water Heaters

Passive Solar Water Heating Systems
Passive solar water heating systems are typically less expensive than active systems, but they’re usually not as efficient. However, passive systems can be more reliable and may last longer. There are two basic types of passive systems:
- Integral collector-storage passive systemsThese consist of a storage tank covered with a transparent material to allow the sun to heat the water. Water from the tank then flows into the plumbing system. These work best in areas where temperatures rarely fall below freezing. They also work well in households with significant daytime and evening hot-water needs.
- Thermosyphon systemsWater is heated in a collector on the roof and then flows through the plumbing system when a hot water faucet is opened. The majority of these systems have a 40 gallon capacity.
Heat Exchangers For Solar Water Heating Systems
Solar water heating systems use heat exchangers to transfer solar energy absorbed in solar collectors to potable water.
Heat exchangers can be made of steel, copper, bronze, stainless steel, aluminum, or cast iron. Solar heating systems usually use copper, because it is a good thermal conductor and has greater resistance to corrosion. Stainless steel is also common in compact heat exchangers.
How Traditional Hot Water Heaters Work
A traditional hot water system will heat the water before its required and keep it hot in an insulated steel tank. Then, as the water sits in the tank, a burner ignites periodically to keep the water at the pre-set temperature. These are generally affordable and reliable hot water systems for homes of all shapes and sizes. In addition, they have low maintenance and repair costs, and replacing an element or two will allow the system to run for 10+ years.
What Are The Most Popular Brands Of Solar Water Heaters
As solar technology continues to find new applications in our daily lives, more companies are manufacturing solar heaters. These are some of the most popular models on the market today.
- Duda Diesel manufactures machinery that uses biodiesel and other alternative fuels. They offer a range of solar water heaters for residential and commercial use.
- Sunbank Solar produces collectors, pumps, plates, and other components for solar water heating systems.
- SunEarth offers a range of solar energy solutions for homes and businesses, including solar water heating systems and elements.
- and Rheem are two of the more popular solar water heaters.
How much you spend on a solar hot water heater depends on what kind of system and what size system you get.
Smaller passive solar water heater systems could cost around $3,000, while a larger active system could run you more than $10,000.

Residential Solar Water Heating
If you have been looking for solar water heating systems, by now you could be overwhelmed with the number of options available to you. Many people do not believe solar water heating can work in Canada or colder USA climates as it is so cold during winter.
In fact solar water heating works incredibly well even during the -40 deg C days that are all too common in a lot of Canada and Northern USA.
Even on these -40 Deg C days the evacuated tube collectors can reach temperatures of over 200 Degrees C, more than enough to boil water!
How many BTUs can the collectors produce! – This is a question that is asked a lot. The answer is not that simple. It really depends on where you live. Anyone telling you “our collectors produce???? BTUs per hour” needs to tell you where they are doing the test as it totally depends on the climate where you live. If you live in Vancouver the amount of solar energy is certainly less than if you live in Victoria on Vancouver Island. The Prairies and Midwest USA tend to have the most amount of sunlight on average. The amount of BTU any collector can produced is based on the amount solar radiation that is present per day at that location.

- Is your house built for the pressure?
- How much is your budget?
With the self-check questions, it would help direct you in choosing the right solar water heater for your home.
Description Of The Technology
Solar hot water panels can be highly efficient, converting about 80 per cent of the energy that hits them into heat. Even on a cloudy day, they will produce some hot water, especially if they are oriented south or southwest to take maximum advantage of the sunâs rays.
They can be used to provide at least a portion of the hot water you use for showers, dishwashers, clothes washers, farm operations and even in-floor heating.
A typical system consists of:
Freeze-protected solar water heaters will keep generating hot water even when the mercury dips well below zero.
