The Supreme Solar 250 LPD Solar Water Heater comes with a stainless steel storage tank with PUFF insulation that keeps the temperature drop to a minimum. Its outer shell is available in both the galvanized metal and stainless steel options and I would recommend you getting the latter as it is less prone to corrosion.

V HOT Non-Pressurized Series Solar Water Heater

V HOT Non-Pressurized Series Solar Water Heater is a great alternative to the SupremeSolar mentioned in our list of the best solar water heater. The only noticeable difference lies in the storage tank construction between the two due to which it ranks slightly low in our list.

Its tank has a decent heat retention capacity and doesn’t allow the water to cool for 60 hours or so.

Things You Need to Know Before Buying a Solar Water Heater

Budget

Confining yourself to your budget is not the best strategy when buying a best solar water heater. Considering the large investment and longer use cycles, don’t be stern with a budget. Try to understand that you will recover your investment in due time and being thrifty will only get you an inferior solar water heater with tiny storage and a slow heating process.

Type

The best Solar water heaters are mainly available in two types FPC and ETC. Both have different use cases and you have to prioritize your need before choosing either of them. FPC stands for flat plate collector solar water heater that uses a copper tubing encased in toughened glass that draws in sunlight and begins the healing process. FTC solar water heaters are costly, have a longer lifespan, and are more suited for tropical regions.

ETC or Evacuated tube collector solar water heaters are best for temperate regions and have a different structure than FPC. They use glass tubes with metal pipes embedded inside and are more suited for temperate regions where temperatures drop drastically. They are cheaper but have less lifespan and are more prone to wear and tear due to their delicate design.

The solar water heater can also be clubbed power source wise, in which one relies only on solar energy while the other one, popularly known as a hybrid solar water heater can be powered by solar energy or electrical energy when feasible. This is the best approach as you can leverage the Sun energy when available and can use electrical power during hazy, rainy, or intense cold weather.

Capacity

The capacity of the best solar water heater implies how much hot water can be stored in the tank for use. It is measured in LPD which stands for liters per day. The average metrics indicate that a 100 LPD solar water heater is adequate for a family of three. As the number of members increase, the capacity or LPD also increases.

The best suggestion would be to go for a solar water heater with 150-200 LPD that facilitates done extra juice in the tank in case guests arrive or you need more hot water than your daily consumers. Industrial solar water heater solutions might require upwards of 500 LPD to 5000 LPD depending upon the industry like dying, sterilization, or other manufacturing sectors.

Type of water

Type of water is an often-overlooked factor and can cause serious complications to your solar water heater. There are two types of water, namely hard water and soft water. Soft water is devoid of minerals and doesn’t clog the pipes and is fit for direct heating solar water heater systems.

Hard water is brimming with minerals and is considered good for health but bad for plumbing and appliances. If you have a hard water supply, then it is best to go for an indirect solar water heating system.

Tank

The storage tank is one of the important features of the best solar water heater and it stores all the hot water until it is drained by the users. The tank material plays a vital role as it should be capable of keeping the water hot for as long as possible. Its interior should be corrosion resistant to avoid internal damage and supply unadulterated hot water to the household.

Modern storage tanks are made with food-grade materials, especially the internal lining as the water can be used for other purposes than bathing.

Water Pressure

Solar water heaters have a pressure regulator that makes them sustain a specific range of pressure into the inlet valve. If the pressure exceeds the mark, there are very few chances that your solar water heater will survive. Make sure to enquire about the admissible pressure range of the solar water heater.

Thermostat

A thermostat enables the best solar water heater to maintain the water temperature up to desired levels that do not damage the skin. To avoid scalding and accidental burns while using hot water, the thermostat must regulate the temperature between 60 to 75 degrees Celsius.

Professional Installation

If you are making a purchase from a renowned brand, the chances of getting a professional installation done is high. Always opt for a licensed and experienced contractor that has experience in the installation of such systems in the past. Make sure that the professional selects the location that has the maximum exposure to and isn’t shrouded by foliage.

Ask the professional about best usage practices and how to operate the solar water heater to ensure the longevity of the installation. Also, enquire about the expected life of the installation and whom to contact if you are moving the unit.

After Sales Service

Buying the best solar water heater is an exorbitant investment and you must examine the after-sales service provided by the dealer. Select the best warranty program, one that covers both major and minor anomalies. Do not cheap out on warranty services as solar water heaters are meant to last 10-15 years on average and you will be stranded after a few years without a robust warranty program.

Maintenance

Good warranty programs cover periodic maintenance that includes frequent inspection of the best solar water heater. Don’t try to fix it yourself as you would end up doing more damage than good.


Final Words

There is no competitor to the SupremeSolar for the title of the best solar water heater. You can trust them for quality components, reliable service and hassle free maintenance. The other trustable options for the best solar water heater can be the offerings from Racold and V-Guard.
