Understanding Solar Hot Water Tanks

October 22, 2018 - No Responses

A solar water tank is an important part of solar water heating system. The type and size of solar hot water tanks you need is often overlooked part of the solar water heaters. Because, there are so many things you need to consider while buying solar water tanks.

What are solar hot water tanks?

The solar hot water tanks work like batteries for electricity and store heat in the form of hot water. Generally, a tank is used to store the heat in hot water. The solar tanks are mainly classified into two categories – pressurized and un-pressurized.

In fact, there is another storage option people can use for solar heat. It’s possible to connect the solar collectors directly to the heating supply that is present in-floor. This heating option can work in some circumstances.

Pressurized Solar Water Tanks

Pressurized solar tanks are like the normal tanks and are heavy. They are designed to store pressurized water for your house. They keep the water entering your house from the city water that will be under pressure from the main city supply. However, an empty 80 gallon tank can weigh around 200 lbs easily.

However, you can utilize a standard tank like a Bradford White tank without internal coils and install your own external heat exchanger onto it. This could work well for a small water heating system like one or two 30 tube collectors. With this solar water tank, you will spend less money on the actual tank and will spend a bit more in money and time by adding external heat exchanger.

In fact, you can buy solar water tanks that are specifically designed for solar hot water systems featured with internal heat exchanger coils built into them. The lower coil is connected to the solar heating system whereas the upper coil can be used for connecting to a backup boiler or connecting to in-floor heating.

Solar water heaters usually need minimal maintenance. However, it’s really important to check your solar water heater at least once a year to ensure all components are in top condition and to keep the system working effortlessly.

Some of the components in a solar water heating system that should be checked include:

Solar collectors –

The solar collectors should remain unshaded. It’s quite common for solar panels that were present under the full sunlight when they were installed in order to receive shading because of the tree growth. You may trim or remove vegetation, if needed.

Dust and dirt particles can impact on the collector performance. During dry and dusty weather, the panel may require cleaning periodically. However, snow and ice melt off, but may require to be removed during heavy accumulations, especially if the panels are placed at a shallow angle.

The solar collectors should be checked for yellowing or cracks and also the seals to make sure that they are still in top condition.

Roof and support

It’s highly suggested to check the penetrations of roof to ensure that there are no problems related to water leakage. The nuts and bolts that are present on racking system need to be checked for tightness and the racks themselves checked for the signs of stress.

Pipes, valves and plumbing –

You should check the pipes and valves for drips and leaked. You can repair or replace them if necessary. It’s important to ensure that the pressure relief valve is stuck open or shut.

Pump –

When it comes to maintaining solar water heaters, you need to check whether the pump is in good condition. If the pump fails, it can cause the system to overheat. The burning smells, high-pitched noises, return pipes and cold supply are the signs that a pump has failed.

Sensors and controllers –

Both the sensors and controllers are the important components of the control system of your solar water heating systems. So it’s important that they should function effortlessly. To inspect a sensor, you can apply mild heat in order to record the rise in temperature. Most controllers come with digital displays that are set to indicate malfunctions, if there is any.

Heat transfer fluids –

Most solar water heaters use glycol or something similar as an antifreeze solution. You should check fluid annually to make sure it is in good condition. If the system is present in a hard water space, the fluid may require to be treated to prevent it.

Solar hot water tanks –

Maintenance of solar water tanks is paramount to operate solar water heaters. You can check them periodically to know whether there are any cracks, leaks or corrosion.

Active Solar Water Heating Systems –

There are two types of active solar water heating systems: direct circulation systems and indirect circulation systems.

Direct Circulation Systems – In the direct circulation systems, pumps circulate household water through the collectors and into the home. They work very well in climates where it rarely freezes.

Indirect Circulation Systems – Generally, pumps circulate a non-freezing, heat transfer fluid through the collectors and a heat exchanger. It helps in heating the water and flows throughout the home. These systems are popular options in climates – prone to freezing temperatures.

multiple pressurised solar tanks

Passive Solar Water Heating Systems –

Passive solar water heating systems are usually less costly as compared to active systems, but they’re not more efficient than its counterpart. However, passive systems can be more reliable and may last longer.

There are two types of passive solar water heating systems: Integral collector-storage passive systems and Thermosyphon systems.

Integral Collector-Storage Passive Systems – These passive systems work very well in climates where the temperatures rarely fall below freezing. In addition to, they work best in a household with significant daytime and evening hot water requirements.

Thermosyphon Systems – The water flows through this system when warm water rises as cooler water sinks. The collector should be installed below the storage tank so that the warm water will rise into the solar water tank.

These systems are considered to be reliable, but contractors should focus on the roof design because of the heavy storage tank. Please keep in mind that they are more expensive than integral collector- storage passive systems.

Hasse Tank

Solar Collectors –

There are two types of solar collectors used for residential applications:

Flat-Plate Collector – Glazed flat-plate collectors are insulated; weather-proofed boxes contain a dark absorber plate under one or more glass or plastic covers.

Unglazed flat plate collectors are used for solar pool heating systems and have a dark absorber plate, made of polymer or metal without any cover or enclosure.

Evacuated Tube Solar Collectors – Evacuated tube solar collectors feature parallel rows of transparent glass tubes. Every tube comprises of a glass outer tube and metal absorber connected to a fin.

The coating of fin absorbs solar energy and inhibits radiative heat loss. These collectors are used frequently for most of the U.S. commercial applications.

Trendsetter - large un pressurized solar tanks

Solar Water Tanks –

Most solar water heating systems require a perfectly-insulated storage tank. Solar water tanks feature an additional outlet and inlet connected to and from the collector.

The solar water heater preheats water before entering the conventional water heater in two-tank systems. But in one-tank systems, the backup heater is combined with the solar storage in a tank.

The solar water tanks are the critical components of solar thermal systems. These tanks allow the system to provide hot water at any time of day, whether the sun is shining or not, since the solar production doesn’t coincide with the peak periods of hot water demand, using in the morning and evening.

Most homes in Northern America use energy worth of $1,200 per year, which entails that there’s definitely something need to be done to reduce the fiscal burden. Almost 18 percent of the power you employ us devoted towards the heating water, which entails that fitting a DIY solar water heater could save you something significant.

However, there are quite a few things you need to consider in order to improve the performance of your DIY solar water heater. Let’s find out what are they:

The size of the solar water tank:

Bigger isn’t always better, but in case of the storage tank, it definitely is. A bigger solar water storage tank maintains its water warmer for a considerable amount of time because of a property is known as thermal inertia. So, the larger your tank is, the more you’ll have in the bank to cover up many cloudy days & approaching cold waters will have a negligible impact when you pull out hot water. And this the best advantage of a DIY solar water heater over a commercial unit as you can up size your storage tank without spending too much.

The Surface Area of the Solar Collectors:

This is a very obvious factor as the larger the collector area the more volume of water you’ll be revealing to the sun’s heat. Once again, the DIY solar water heater system has a plus over the commercial ones as you have the luxury to expand the size with a negligible increase in effort and material expense.

Collector materials used:

Typical solar collectors feature copper tubing affixed to a copper heat soaking fins since this offers the optimal thermal performance at a hefty cost. However, DIY solar water heater collectors can be built at a much lower price; employing copper tubes allied to aluminum fins & acquire nearly the same performance.

Insulation in solar water tank & piping:

 It is essential to insulate the water tank perfectly because the reserve heat lost the longer the waters will remain warm & the less the DIY solar water heater unit has to run to produce heat again.

Proper location: Your DIY solar water heater collectors must be placed in a place where it’ll get as much exposure to the sun as feasible and that entails making certain that obstacles like trees are considered prior to deciding on where to place them.

Keep these above-mentioned points in mind and you will definitely be able to make the most of your homemade solar water heater system. Good luck!
