The Best Vacuum Solar Tube

Solar water pool collectors are unpressurized solar collectors meant to heat the pool water directly. Cold water enters into the manifold from the pool, sinks to the bottom of the tube, and once heated a little bit, will rise back up to the top of the manifold and exit with the water flow. Pool collectors are the most efficient way to heat water because they come in direct contact with the heated surface in the tube and operate at low temperatures which will allow for minimal heat loss through the tubes and manifold, if any at all.

a box of 10 triple-insulated high-performance Clean Republic solar vacuum tubes, also known as Solar Evacuated Tubes. These high-quality solar tubes can boil water using only the power of the sun! They are great for hobby projects, and for building solar air and water heating systems. We have excellent customer service and a 100% shipping protection guarantee (make sure any other tube suppliers you’re considering offer this type of guarantee because these tubes are fragile). These tubes soak up the energy in sunlight, absorbing it into the super-insulated inner tube of their incredible double-wall heating system. Once inside, the heat of the sunlight is trapped inside the inner wall of the inner glass tube. Highly-reflective layers of steel, aluminum, and copper trap the infra-red energy of the sunlight, and the nearly perfect vacuum between the inner wall and the outer transparent wall protect the inner tube from heat loss due to convection, just light a high-grade drink thermos. This thermos effect can quickly heat water to boiling temperatures in direct sunlight, and keep the water well over 100 degrees even over night!

Duda Solar Water Heater Collectors are the most efficient solar collectors on the market. The evacuated tubes retain heat much better than flat panel collectors and therefore can work much more efficiently in cold climates. They also have a unique capability of obtaining higher efficiencies while the sun is at an angle in the east or west through passive tracking in the tubes. SRCC Certified and eligible for the 30% Federal Tax Rebate. May also be used with Duda Solar Aluminum Reflectors.

This Solar LightBlaster tube skylight will bring natural light into your metal-roofed shed. A clear dome is installed in the roof which collects the sunlight which is then transported down into your shed through a short reflective tube connected to a diffuser inside your shed’s ceiling. Super easy to install and it makes a world of difference to your dark shed. (Also known as solar tubes, light tubes, sun tunnels, daylight pipes, sun scopes & tubular skylights.) SPECS: Shaft Opening: 7 3/8″ diameter, Roof Hole Template: 8″ diameter, Exterior Dome: two piece acrylic dome assembly in an aluminum trim, Installed Height when installed on ½” plywood, the unit: 7″ tall, Base Flashing: 13 3/4″ diameter, Material: spun aluminum .080 thickness, Interior Trim Flashing: 10″ diameter, Interior Reflector: 7 3/4″ diameter.

Superior "Black base" high-voltage power pentode. Most common power pentode found in British amplifiers such as Marshall, Hiwatt, Laney, and Sound City. The EL34EH defines the classic British rock sound of the 1960s and 1970s. Perfect EL34 for vintage equipment and for improved performance of modern amps. Extremely musical and predictable, with a sound that is rich, smooth, and detailed without being edgy.

Originally found in vintage British amplifiers such as Marshall, Hiwatt, and others

These double chamber water tubes are better able to stay securely in place and won’t roll like single-chamber alternatives. An added benefit is that if one side becomes punctured, there is still enough weight from the other chamber to hold your cover down. These vinyl water tubes are up to 35% heavier than other versions on the market and yield significantly more strength and puncture-resistance. Each double chamber water tube features a no-leak valve and is easy to fill using a standard garden hose. Sold in a 6 pack, each tube is 8 feet long and features dual water chambers in a black color.
