Why this is the most Efficient Solar Water Heater in Malaysia?

1) Using Evacuated Tube System 
V66 has 30 Tubes which has almost double the surface area compared to a regular Flat Panel Solar. Tested to be able to work on rainy days as long as there is sunlight and not completely dark sky.

2) Less Heat Loss

With higher efficiency of the tubes to absorb the radiation from the sun, we will need to retain the heat to prevent heat loss. V66 Evacuated tubes are made of two-layer glass with vacuum in between the layers. The vacuum is similar to thermos flask that we use to keep water hot, vacuum is a great insulator to retain heat.

Image

3) Multiple Riser

V66 Solar comes with 30 Evacuated tubes that directly heats up the water from the bottom of the tank, so water in the tank gets heated up faster and more evenly.

Image

1) 316 grade stainless steel inner tank.
316 contains a minimum 2.0% molybdenum which makes it much more corrosion resistant than 304. As water contains chlorine and other harmful contaminants, to reduce the risk of corrosion, V66 Solar is using 316 grade steel, that is used for marine industry, highly resistant against corrosion.

2) Seal Connection System or Close Loop System.
Majority brands in Malaysia are using Wet Tube or Water in Tube, whereby the tubes are connected directly to the tank and water flow into the tubes. The common problems with this system is low durability and high water leaking issues. Connection between tubes and tanks are secured using silicone seal that are prone to deteriorate and leak over time due to the heat. Moreover, if one of the tubes break, hot water from the tank will leak out and the solar water heater is totally not usable. Aquasolar V66 on the other hand is using a more advance tube called HEAT PIPE, heat is transferred through the copper pipe in the tubes and there is no water flowing into the tube, hence ZERO Leakage tubes. Connection between tank and tubes are sealed, so no water can flow out from the tank into the tubes, this solves the common leaking issue found in regular evacuated tube solar water heater.

Vacuum Tube

A solar vacuum tube works similarity in design to a coffee thermos. It consists of a two-layer glass with a vacuum in between the layers. The outer layer of the solar tube is made of borosilicate glass, which has very low iron content and allows 98% of light energy to pass through.

Vacuum Tube Heat Pipe
Size: 1800 x 58 mm Heat Pipe Tubes
High Borosilicate 3.3 Glass 0.6 mm Thickness
Efficiency: 91% - 94% 14 mm Condenser
Three-target Tubes Anti-Freezing Function
Top Efficiency
