The Sun Cloud Heater – An Efficient Portable Heating Solution

What is a Sun Cloud Heater and How Does it Work?

A sun cloud heater consists of a parabolic reflector that concentrates sunlight into a focused beam, heating a special coil filled with mineral oil or glycol fluid. A small solar panel powers a silent fan that blows air across the heated coil, providing a stream of warm air just like a traditional patio heater.

The parabolic reflector tracks the sun’s movement throughout the day, focusing its rays on the heating coil. Adjustable tilt and rotation settings allow the reflector to capture the optimal amount of sunlight. The reflector’s shiny mirrored surface intensifies the sun’s thermal radiation, magnifying its heat to temperatures over 390°F at the coil.

This concentrated solar energy heats the internal fluid, which then transfers the heat to the air stream from the fan. The warmer air flows down over a 6-10 foot radius, gently warming anyone nearby. Once the sun sets, the heater turns off automatically.

Benefits of Sun Cloud Heaters

Here are some of the main advantages sun cloud heaters offer over propane and electric patio heaters:

  • Renewable solar power – Sun cloud heaters rely only on free solar energy and not fossil fuels or electricity.
  • Lower operating costs – No need to refill propane tanks or pay electric bills to run it.
  • Eco-friendly – No emissions or pollution since they run on solar power.
  • Quiet operation – The fan produces minimal noise compared to propane heaters.
  • Safe – No open flames, fumes, or risks of gas leaks.
  • Low maintenance – Sun cloud heaters have few parts and require minimal upkeep.
  • Long-lasting – Can provide 10+ years of reliable service with proper maintenance.
  • Thermostatic control – Automatically adjusts based on the desired temperature.

For homeowners wanting an efficient and cost-effective way to extend patio season without harming the environment, a sun cloud heater is an excellent option.

Types of Sun Cloud Heaters

There are a few different designs of sun cloud heaters available:

  • Parabolic reflector heaters – The most common type with a dish-shaped mirror that tilts and rotates to focus sunlight on a central coil.
  • Fresnel lens reflector – Uses a thin Fresnel plastic lens to concentrate sunlight into a stationary heating element.
  • Evacuated tube models – Rows of solar evacuated tubes containing heat pipes that collect and magnify heat.
  • Solar updraft models – A vertical design that heats air within a glass enclosure that rises and circulates.

The parabolic reflector type usually provides the highest efficiency and intensity of heat. Fresnel lens models take up less space but don’t concentrate sunlight quite as strongly. Evacuated tube and updraft styles work well but are typically larger and more expensive.

What to Look for When Buying a Sun Cloud Heater

Here are the key factors to consider when selecting which sun cloud heater best fits your needs:

  • Heating capacity – Measure the area you want to heat and look for a heater rated for that square footage.
  • Reflector size – Larger reflectors (8ft+) capture more sunlight and provide greater heat output.
  • Wind resistance – Models with sturdy bases stay focused in windy conditions.
  • Thermostat – This automatically adjusts the fan speed to maintain a preset temperature.
  • Adjustability – Look for tilt/rotation features to optimize sun alignment.
  • Durability – Choose powdercoated aluminum over plastic parts for longevity.
  • Warranty – Heaters with at least a 2-3 year warranty provide peace of mind.

Also consider automated sun tracking, overheat protection, and the type of stand/base that fits your placement needs. Investing in a high quality sun cloud heater will pay dividends for years to come.

Where Should You Position a Sun Cloud Heater?

Proper placement is crucial to maximize solar collection and heating effectiveness. Here are some sun cloud heater positioning tips:

  • Face the reflector toward the southern sky to capture the most sun exposure throughout the day.
  • Avoid shade from buildings, trees and other obstructions that limit sunlight.
  • Place in an open area to allow the reflector to tilt and rotate unhindered.
  • Elevate the heater at least 7-8 ft high so warmth can circulate downward.
  • Keep the area below the heater clear of furniture that may block the heat.
  • Position it near seating/dining areas for the best comfort and enjoyment.

Proper alignment is also crucial – make sure the reflector is aimed perpendicular to the sun’s rays whenever possible. Some experimentation with placement may be needed to find the optimal spot.

How Much Do Sun Cloud Heaters Cost?

Sun cloud heaters range in price from 0 on the low end for small portable models up to 00 or more for large high-output commercial heaters. Expect to pay:

  • $200-$800 for simple parabolic and Fresnel lens residential models.
  • $800-$1500 for larger parabolic heaters to cover up to 700 sq ft.
  • $1500-$2000+ for heavy-duty commercial/industrial strength parabolic heaters.
  • $2000+ for evacuated tube and solar updraft style heaters.

Less expensive units often have plastic parts and weaker reflectors that are prone to cracking. Investing in a quality stainless steel and aluminum commercial heater will provide the best durability and performance.

Are Sun Cloud Heaters Safe and Legal?

When used properly, sun cloud heaters are completely safe and legal to operate. The heating element remains cool enough to touch, and the intensity of the sun’s rays naturally dissipates a few feet from the reflector. There is no open flame, fumes or risks of gas leaks, making them much safer than propane heaters.

Just take sensible precautions such as:

  • Never directly look into the focused sunlight near the reflector.
  • Don’t touch the reflector while it’s aimed at the sun.
  • Keep the sun’s reflection path clear of people, plants and property.
  • Supervise children and pets around the heater.
