Why Vacuum Tubes for Water Heating?

Vacuum Tube Solar Collectors (also called Evacuated Tube Solar Collectors) are very useful in northern climates for solar heating of water mainly for space heating and domestic hot water heating. They are among the best performers in Canadian weather and in the northern part of the US.

Vacuum Tube Collectors are the central part of any Solar Water Heating system.They convert solar energy into thermal heat via the vacuum tubes (for more details please go through our blog: How do Vacuum Tubes Collectors works?)

How much money do you save by producing thermal heat by Vacuum Tube Solar Collectors?

Harvested solar energy from the sun is free, but converting that energy into useful and economical use is the most expensive part. Proper Planning and Design of any solar installation is the key for a successful solar project: Lowest possible cost, highest possible saving and fastest return on investment.

Simulating Solar energy based on geography and demographic isn't a simple task. Our Technical Team has crafted a blog to make easier to estimate saving in most major Canadian cities: How much energy can you solar water heater generate?

A much easier way to size and select your solar water heating system is to contact our technical team or simply filling this online FORM.
