Best Solar Water Heater Buying Guide

What Type Are You Looking For?

Here are the different types of solar water heaters. Choose from the given alternatives based on your needs.

1. Flat Plate Collectors

These varieties contain an in-built copper tube, which is fitted in a sequential manner of matching cells that connect via two pipes. More so, the flat plate is kept within an insulated container and enclosed by tempered glass.

2. Batch Collectors

The other term for batch collectors is Integrated Collection Storage systems. These resources heat water in tube-like structures that are enclosed within a box. The heated water is stored in the compartments until you draw the water. In such containers, water is storable for prolonged durations, due to which the water becomes very hot. Thus, most solar water heaters come with a tempering value that prevents any scalding incidents when you twist the tap. The valve mixes cold water with the hot water to keep the water temperature at tolerable levels.

However, you must not use batch collectors if you’re living in areas that experience extreme cold climatic conditions.

3. Closed-Loop Variants

The closed-loop solar device system is known to work indirectly and uses a non-freezing liquid to redirect the heat of the sun’s rays to the water through a storage tank. The sun’s thermal energy then warms the fluid within the solar absorbers and the heated fluid continues to flow via the storage tank’s heat exchanger for transmitting the heat to the water. The non-freezing water passes through the same cycle and collects inside.

4. Evacuated Tube Collectors

The evacuated tube collectors are rated the highest in efficiency among the different types of collectors. They come with a metal-based tube, which conserves water and is enclosed in a larger-sized glass tube. The space between both tubes creates a vacuum for retaining the heat emanating from the sun.

Solar water heaters are grouped by their respective circulation system. In the following details, we discuss the different models as per the flow system.

5. Direct Models

This solar water heating system has a circulation system that pumps the water via the absorbers to be directly warmed as a result of the sun’s hot rays. After the water heats up, the warm water is pushed into a tank and is usable.

Location Matters

The location of your house makes for an important consideration when making your selection among the available solar water heaters. If you’re residing in warm regions, then opting for a solar water heater is a judicious choice. Because you can be assured to receive adequate amounts of hot water to meet your household needs.

On the other hand, if you live in regions that experience cold climates, you will need a suitable solar collector. More so, you have to factor in the possibility of your system freezing. To avoid such issues, you have to install a drain back tank system that maintains the water temperature and prevents the pipes from bursting.

Are You Environmentally-Conscious?

If you’re looking to make your contribution to the environment, then you have to adjust your lifestyle habits accordingly. As such, you must not shower for longer than required. Plus, you must wash your clothes only in cold water. You must also adjust the temperature of your existing water heater to acceptable levels.

As part of your efforts to go the environment-friendly way, you should also pick solar water heaters that do not require extra energy for their operation. Go with basic passive systems; they use thermodynamics to energize the circulation pump.

Opting for a solar-engineered circulation pump is one more way of making your contribution to making the world greener.

Gauge Your Water Requirements

The efficacy of your residential solar water heating systems depends on the number of family members and their lifestyle. In cases of large-sized families, the wide water collectors are deemed suitable and a larger holding tank suffices for heating water.

Conversely, if your family size is small, then the passive systems that heat water in batches are advisable.

Take into account your daily water needs and follow by opting for models that serve the given purposes suitably.

Summing Up

Solar equipment helps in preserving the environment by reducing our dependence on fossil fuels. As a consequence, we can reduce our carbon footprint and the release of greenhouse gases. For this reason, solar energy is considered to be a eco-friendly alternative while paving the way for a greener future – not only for us but also for our future generations.
