Natures Comfort

Solar Water Heaters
A natural, continual, permanent energy source.











Preserving our Earth & Preparing Ourselves


A solar water heater is one of the most effective ways of cutting a household's carbon footprint by reducing our reliance on the grid.
By offsetting the use of electricity, gas or heating oil, using solar water heaters can also provide financial savings by reducing energy costs.


NATURES COMFORT uses sunshine.  It is an Energy Star Certified solar water heating system. The NATURES COMFORT SM-V30 Solar Water Heater will heat or preheat your water and can cut your annual hot water costs in half.  This Solar water heating system is designed for use with an electric or gas back-up water heater. 

Our Present & Future:

Food, Clothing and Shelter are our basic needs.  If anything goes wrong with our way of life as we know it, we will have to rely on our ingenuity for preservation.  We need to be aware of what could and will go wrong.  We need to have a back-up system in place, just as we do for our phones and computers.

Where we are now:  Our shelter and clothing are in place.  Food: MRE's (meals ready to eat), canned food and bottled water all should be stored in our homes. Portable water purification systems are readily available.

However the question begs:  The availability of electricity for heat and for pumping water.  In many parts of the world electricity is severely limited or only available during specific hours.  In those areas, the use of Solar Energy is relied upon.  It is from this we must take heed.

With the advancements in solar technology and amazing science, we now can use the sun to help heat our homes and water.  Using electricity to pump the water or relying on urban communities for water pressure, we  would be able to live comfortably.

Thus coal & wood boilers and solar water heaters.  There are many companies out there making such heaters and there are regulations regarding emissions for such products.  There is one company that stands out above the rest: NATURES COMFORT.   NATURES COMFORT is committed to reducing our demand on the grid.  This company offers a variety of ingenious products to fit the needs of heating residential dwellings and large-scale commercial operations.  (In fact the inventor is working on burning recycled tires so hot, it would burn completely CLEAN!  But let us save that for later).  We are focusing on YOU and your families needs. 

What is a Solar Water Heater?  A Solar water heater uses the solar energy from the sun to generate heat (not electricity), which can then be used to heat water for household use, space and pool heating, industrial processes or even solar cooling. Solar energy is the primary energy source for our planet.  It is responsible for providing energy for plant growth and providing the warmth that makes our planet habitable. While solar water heater devices have been around for over 100 years, the last 20 years have seen significant advances in absorber coating technologies, resulting in solar collectors that can reliably convert >50% of available sunlight for domestic hot water supply. 

The Various Circulation Systems:

Direct systems circulate water through solar collectors where it is heated by the sun. The heated water is then stored in a tank, sent to a tankless water heater, or used directly. These systems are preferable in climates where it rarely freezes.
Closed-loop, or indirect, systems use a non-freezing liquid to transfer heat from the sun to water in a storage tank. The sun's thermal energy heats the fluid in the solar collectors. Then, this fluid passes through a heat exchanger in the storage tank, transferring the heat to the water. The non-freezing fluid then cycles back to the collectors.
Active, or forced-circulation, systems use electric pumps, valves and controllers to move water from the collectors to the storage tank.
Passive systems require no pumps. Natural convection moves water from the collectors to the storage tank as it heats up.
Evacuated tube collectors are the most efficient collectors available. Each evacuated tube is similar to a thermos (in principle). A larger glass tube on the outside surrounds a glass or metal tube containing the water. The space between them is a vacuum, so very little heat is lost from the fluid.  These collectors can even work well in overcast conditions and operate in temperatures as low as -40F without the use of freeze protection.  It is the Evacuated-tube solar collectors that are the most cost effective and efficient units in the market place and it is the system being offered here.

The NATURES COMFORT:  SM-V30 Solar Water Heater has a tank capacity or 66 gallons.  It features parallel rows of transparent glass tubes. Each tube contains a glass outer tube and metal absorber tube attached to a fin. The fin's coating absorbs solar energy but inhibits radiant heat loss.  The Frame and Tanks: The Inner Tank Material: SUS304-2B Stainless Steel, 23-26 Gauge.  Outer Tank Material: Painted Steel, 26-29 Gauge.  Assist Tank: 2 gallons.  Evacuated Tube Collectors combine the high efficiency performance of evacuated tubes with rapid heat transfer capacity of heat pipes to provide a collector that can operate efficiently in almost any climate providing hot water for residential or commercial solar water heating projects.  It is these Evacuated Tubes that are responsible for absorbing sunlight and converting it into usable heat. Tube Design: The evacuated tube design was originally developed in the 1980s and has proven to be extremely robust.  Referred to as the "Sydney" tube, "twin-tube" or "all-glass", the glass tube is really a double glass tube, which is fused at the top and bottom.  The inner tube has a solar absorbing coating, and the space between the two tubes is evacuated to form a vacuum.  Strong Glass: The tubes are made from a type of glass called Borosilicate, the same base material as used in many Pyrex glass products used in kitchens around the world.  Borosilicate glass has the characteristic of being very strong and also has excellent light transparency (>92% @ 2mm thick). The wall thickness of the glass greatly impacts the strength, longevity and naturally also the cost.  Natures Comfort evacuated tubes are made to strict requirements that exceed the industry standards, including a 1.8mm thick wall ensuring excellent strength and resilience to hail impact up to one inch.  Vacuum Insulation; The name "evacuated" is used to describe the process that expels the air from within the space between the tubes, forming a vacuum.  A vacuum is an excellent insulator against heat loss, and so evacuated tubes are able to operate very efficiently when there is a big difference between the inside of the tube and the outside ambient air.  For this reason evacuated tubes are the ideal choice for high temperature hot water applications or locations that get cold in the winter. Barium Getter:  In order to help maintain the vacuum over the 15-20 year life of the evacuated tube, a barium getter "soaks up" any remaining gases in the evacuated chamber plus any fresh gases such as Nitrogen that can slowly permeate through the glass over time, a process known as out-gassing.   This barium layer also provides a visual indication of the vacuum status; the silver-colored barium layer turns white if the vacuum is lost making it easy to identify a fault tube. Solar Absorber:  The absorber coating comprises a base layer of Aluminum on the outside of the inner glass tube followed by thin layer of the dark colored AL/N material.  These coatings are applied using a method called dc reactive sputtering, which is extremely reliable.  Efficiency: The combination of the highly efficient absorber coating and the vacuum insulation means that the coating can be well over 200oC / 392oF and the outer glass is cool to touch.  In strong sunlight, each evacuated tube can provide over 60 Watts / 204 Btu of water heating output.  Thus allowing 72 hours of heat preservation and even gain heat on cloudy or overcast days.

AS NATURES COMFORT uses sunshine it is an Energy Star Certified solar water heating system. The NATURES COMFORT SM-V30 Solar Water Heater will heat or preheat your water and can cut your annual hot water costs in half.  This Solar water heating system is designed for use with an electric or gas back-up water heater.  As this back up maybe required for extended cloudy days or times of increased demand. Conventional storage water heaters with or without thermostats, tankless or demand-type water heaters will do as well.
