duda solar 200l active split system

Today, we review the best solar water heater for home and the Water Solar System Price. As the name suggests, a solar water heater uses the energy from sunlight to convert it to heated water. It captures the sun’s rays and transforms them into heat so they can be used as a heater for your home. It is an economical and renewable form of energy that uses a thermal collector to gather sunlight and convert it into energy.

They can be heated directly or by using light-concentrated mirrors. These heaters come in active or passive forms and only use water and a working fluid to operate. Some solar heaters, however, are hybrids with gas or electric heaters.

How Does a water solar system Work?

Solar water heaters function by transferring the heat or energy collected from the sun to a tank. This is done using a separate circuit and heat exchanger. The heat the panel collects from the sun is used to heat up the water in an effective manner and it then flows through a circuit of pipes in a copper coil inside the tank that stores the hot water. They come in a wide variety of designs and styles, and their functionality depends on the type of collector and circulation system installed in them. 

How to Choose a water solar system

Now that you have some knowledge of how a solar water heater functions, let’s go over the main features you should consider before choosing one. There are many different types to choose from, so you need to decide which one suits you the most.


You have to choose a solar water heater that meets your daily demand for hot water. If you have a large family that uses at least a 1000 gallons of heated water per day, then you need to get a bigger solar water heater with a larger storage capacity.

Easily Usable

You also have to check whether the solar water heater is a hassle to install on the roof  or is too complex for you to not understand. The design should be low-maintenance and should be able to be set up quickly and easily so you do not have to face any difficulties later on.

Longevity and Durability

Since solar water heaters are placed outdoors, they face a lot of abuse at the hands of climate changes and weather conditions. For these reasons, you need to find a unit that can withstand these harsh conditions and is built with high-quality materials that are not only durable but also safe to use.

Best Overall: Duda Solar 200L Active Split System

  • Gallons: 53
  • Type: Active (indirect)
  • The High Points: Great for cold climates as it’s winter resistant.
  • The Not-So: May not be great for those who travel frequently.

Duda is known in the solar water heating industry as being a reliable and high-quality brand. They are SRCC-certified and can be used for federal or state tax credits and exemptions, which is a great incentive for on-the-fence homeowners to commit to a solar water heating system.

The 200L Active Split System is great because it allows homeowners to heat their water on the roof or other sun-heavy location and store their water in a protected tank close to where it will be dispensed.

This prevents major heat loss by keeping the water warm even with the ambient air temperature is low. The system also utilizes a single copper heat exchanger coil that’s placed near the upper part of the tank to strategically heat the water as it’s being used, so the cold water at the bottom of the tank can be heated later.

What Do Reviewers Say?

Reviewers are generally happy with the efficiency of the Duda solar water heating system. Using the Duda 20 tube solar collection rack, homeowners have reported that they can heat water quickly with only a few hours of direct sunlight and partial shading.

Others have concerns about the rise in temperature that may occur when the homeowner is away from the system. The expansion tank regulates the excess hot water but it cannot withstand more than a few days. This may be a problem for those who travel frequently during the summer months.

Features & Considerations

Duda Diesel’s popular solar water heater comes in a variety of sizes, but the 200-liter (53 gallon) system is the best for residential use.

Its water tank rivals standard electric or natural gas systems but eliminates the need for costly energy consumption as it’s equipped with a solar water heater collector. The storage tank itself consists of food grade stainless steel.

It also includes an 8-liter expansion tank to help prevent failures in the system due to stagnation. This means your solar collectors won’t be damaged if the amount of solar energy exceeds the amount of water you’re heating at any given time. There’s also a thermostatic mixing valve to prevent scalding.

The solar collector is fitted with twenty 14mm solar tubes on a 45-degree stand, which can easily be exchanged for a 37-degree or slope roof stand if you plan on mounting it elsewhere.

The solar collector transfers the heat of the sun to your water pump through an indirect circulation system. The Duda kit includes the necessary two gallons of food-grade inhibited propylene glycol used in the process.

The kit also includes a solar water heater working station which regulates the split pressurized system by connecting the collectors, storage tanks, relays and sensors. It uses a circulation pump, pressure gauge, pressure relief valve and check valve.

Other safety systems include an automatic air vent for purging air from the top portion of the system, and a submersible water pump for the initial air purge and charging of fluid into the system.Click to See Price

solar water heater for home

sunbank 40 gallon solar water heater

Runner-Up: Sunbank 40 Gallon Solar Water Heater

  • Gallons: 40
  • Type: Passive (thermosyphon)
  • The High Points: Requires virtually no maintenance.
  • The Not-So: Not as efficient as an active system.

The Sunbank 40-gallon solar water heater is a no-frills integrated system that can be easily installed and maintained by any homeowner.

The passive water heating is great for small households living in mild climates that receive a lot of sunlight. With no-moving parts or extra pieces, the Sunbank system is a great starter kit for those who may be intimidated by more intricate and advanced solar heaters.

With a SRCC certification, the Sunbank is a cost-efficient way to cut down on expenses. Their affordable price point and 10-year warranty guarantee financial security. By using a passive solar system, homeowners can save as much as $600 per year in energy costs.

What Do Reviewers Say?

Most reviewers are pleased with their Sunbank systems as they are efficient and reliable. One reviewer even claimed that the water is too hot. In general, homeowners have been able to easily assemble and install the systems on their own.

However, several homeowners have purchased dual 40-gallon systems to increase the capacity of their hot water tanks as a single system is not enough to service an entire family.

When buyers had concerns about their water intake or configuration, the Sunbank staff were eager to assist and advice on the best setup. For those DIYers with a big household, a dual Sunbank system may be the best option.

Features & Considerations

The Sunbank system includes a tank, evacuated tube collectors and bracket. The 40-gallon tank is made with stainless steel.

The high-density polyurethane insulation also provides heat retention to prevent extra heat loss in low ambient temperatures. The size of the tank is adequate for small households of one to three people. Those with larger families may want to consider an 80-gallon tank instead.

Sunbank’s system is passive, rather than active, so it doesn’t require pumps, glycol heating fluid, or any moving parts. This makes installation much more convenient for novice plumbers or DIY homeowners.

Passive systems are also cheaper than their active counterparts and are a great “starting point” for those looking to enter the solar market.

Since the system doesn’t use pumps, it’s pressurized. The system relies on municipal or well water pressure to move the water in and out of the tank. Once a faucet is turned on, the cold water is pushed into the hot water tank, which then pushes the hot water to your faucet.

The 15 evacuated solar tube collectors are mounted on a corrosive resistant aluminum bracket. Each tube can collect 92-96% of the sun’s energy in prime conditions.

The tubes can be used as a pre-heater for an existing system or as a stand-alone unit. They are best suited for roofs that receive an adequate amount of sunlight.Click to See Price

sportneer solar shower bag

Best for Camping: Sportneer Solar Shower Bag

  • Gallons: 5
  • Type: Panels
  • The High Points: Allows for temperature control.
  • The Not-So: Can only provide enough hot water for a few short showers.

As far as portable showering is concerned, Sportneer’s Solar Shower Bag ticks all the boxes. With a durable design and host of features, campers can now have a hot shower even in the wilderness. However, this bag is not a substitute for indoor showering or advanced solar water heating systems.

The design of the Sportneer is simple: a small, integrated solar panel heats up the water which is held in an insulated PVC bag. With a 5-gallon capacity, the bag can provide enough showers for a solo outdoorsman or a small crew. It also comes equipped with a temperature bar, shower head, storage pockets and a carrying case.

What Do Reviewers Say?

Buyers are pleased with the convenience the Sportneer Solar Shower Bag provides. They claim that it’s great for camping or outdoor activities as it’s portable and durable. One complaint that seems to be common among buyers is that the shower head is too small.

Some have tried unsuccessfully to use it as an at-home product, but it is not really a suitable alternative for a normal shower. However, some use it as a backup for power outages or other emergency situations.

Features & Considerations

The Sportneer Solar Shower Bag is the perfect accessory for avid campers. The bag is made of durable PVC material and comes with a hook for temporary installation on a tree, wall or car.

On the front of the bag are two net pockets that can be used to store bath products. It only weighs 1.2 pounds and can be easily rolled up and stowed in its mesh carrying case during outdoor excursions.

With a built-in solar panel, the shower bag can heat water in direct sunlight in as little as 3 hours. It includes a temperature indicator on the back so campers can add cool water if the bag exceeds comfortable levels. With a 5-gallon capacity, the bag can hold enough hot water to last a few short showers.

Attached to the bag is a shower hose with nozzle that simulates a real shower experience. The hose is connected to a water inlet with a sealed cap to prevent leakage. If the hose does manage to leak, the kit includes cable ties that can be used to prevent further leaks by closing off the connections.Click to See Price

sunquest 3 2x20 solar swimming pool heater

Best for Swimming Pools: SunQuest 3-2X20 Solar Swimming Pool Heater

  • Gallons: N/A
  • Type: Flat-plate (unglazed)
  • The High Points: Can raise the temperature of a swimming pool by up to 10 degrees.
  • The Not-So: Can’t be used for residential purposes.

The SunQuest Solar Swimming Pool Heater is a great option for those with a pool at home. During off-seasons, like spring or fall, the SunQuest can keep your pool at a comfortable and ambient temperature. With a maximum 10 degree increase in temperature, you can swim at any time of year.

The system works by pumping the water through unglazed tubes that heat the water before it’s returned to the pool. It requires very little installation or maintenance and can be used for above or below ground pools. Even better, the sleek black heating pad won’t be an eyesore in the back garden.

What Do Reviewers Say?

Buyers are happy with the effectiveness of the heater. A standard pool pump works well with the system. However, the pool will not be very warm during cloudy days or cool nights.

One note is that a pool skimmer will not work properly when you use both at once. It’s a good idea to use a diverter valve to bypass the heater while the filtration system is operating. Overall, the system is a great value and can help to extend swimming season for the family.

Features & Considerations

The SunQuest system is unique in that it heats both in-ground and above-ground pools through an integrated unit. It works with the pool’s pump to push water through the heated coils and back into the pool, raising the temperature by up to 10 degrees.

It’s a very cost-effective way of extending the swimming season when spring or fall temperatures drop below comfortable levels.

The kit comes with two 2 by 20-ft. panels that you can simply place on the ground or a rack near the pool. The system is UV protected and won’t be damaged by the sun. It also comes with a “MAX-FLOW” design that improves the water circulation.

You will need to purchase additional piping to complete the installation. This will connect from your pool to the heating pads. The system comes with standard connectors to attach to flexible or rigid pipes and hoses.Click to See Price

clean republic heat streamer

Best for Off-Grid Cabins: Clean Republic Heat Streamer

  • Gallons: 5
  • Type: Passive (integral)
  • The High Points: The system is very cheap and easy to use.
  • The Not-So: It will only heat very small batches of water at a time.

The Clean Republic Heat Streamer is not a hugely popular option, but it’s certainly effective. For those looking to toe-dip in solar water heating, this system is for you.

With a small array of solar tube collectors, the integral passive solar heating system can warm up to 5 gallons at a time.

The small capacity and easy installation of the Heat Streamer is perfect for those who have an off-grid cabin. You can use the system to boil water for cooking (or, perhaps look into a solar oven), showers or general heating. However, it’s not the best option for those living in an average-sized household with more than one person.

What Do Reviewers Say?

Overall, buyers are happy with the Clean Republic Heat Streamer. While it’s not a fancy or high capacity system, you get what you pay for. Some buyers have used it for thermo projects while others have installed them in hunting cabins or to heat pools.

One buyer was not happy with how the tubes fit into the frames. The frame fails to cover the top of the tubes which will lead to rain damage if you install it outside in inclement weather. The buyer circumvented this issue by purchasing weather stripping.

Features & Considerations

While 5 gallons is not much water, you can expand the system by including more units. It’s great for cabins or bunkers that you use infrequently for light showering or kettle boiling. You can heat the water in as few as 4 hours if used with their solar water heater pump.

The tubes heat water at a rate of 165 watts. If can increase the temperature of input water by 37 degrees if the water is being circulated at a flow rate of 5 gallons per hour. Each unit is made of copper manifold pipes with continuous u-bends, minimizing space and maximizing efficiency.

The system can handle up to 100psi, which is suitable for most city supply water. However, closed systems, like those used in remote locations, must be installed with a relief valve. Overall, installation is fairly painless and requires little assembly.Click to See Price

What Do Reviewers Say?

Unfortunately, there are no direct consumer reviews for this kit. The kit also includes a number of different brands.

While each product is of high quality, it’s still important to first check your specifications and consult a local expert if you have questions before purchasing.

Features & Considerations

This solar water heating kit includes everything you need to set up an advanced residential system without a solar installation company. The kit includes various products of brands, including SolarStor, SunRain, RESOL, Aurora, Spirotech and more. However, the Northern Lights Group compiles and certifies the kit, which is a company that provides solar solutions for DIY homeowners.

The solar heating package can service a family of four and doesn’t require any complex installation like soldering or electrical wiring. It also includes a RESOL DeltaSol Bs+ controller that allows for optional heating of a secondary zone, like a pool, hot tub, or furnace. This is a huge bonus for homeowners.

SunRain’s TZ-58 1900 30R vacuum tube collector heats the 18 liters of ProSol LH-T fluid that comes with it, which then transfers to a 50-gallon SolarStor tank.

The tank has a built-in heat exchanger with a 4.5Kw backup heating element that’s UL and CSA certified. For safety, there’s an 18-liter high temp solar Zilmet expansion tank and a Spirotech AutoClose solar air vent.

The kit also includes a RESOL FlowSol solar pump station, Aurora Solar Flex steel piping that’s pre-insulated and weather proofed, and a complete manual for installation. The company offers free technical support if you encounter challenges during installation. Overall, this is one of the most comprehensive kits on the market.Click to See Price
