These integrated solar tanks have evacuated solar tubes to heat the water but come with the added benefit of having a tank built in saving you a huge amount of money.

In Canada a basic plain 80 gallon tank will cost you anywhere from $500 to $1000, and a solar tank with a built in heat exchanger coil and you can pay anywhere from from $800 to $3000+ dollars JUST for the tank.
  • Ideal for swimming pool heating, homes, off grid cabins, commercial car washes and other commercial projects.

  • A simple cost effective solution for off grid cabins and/or small homes.
  • Install multiple units to provide extra hot water.

  • Can be used anywhere a “normal” solar collector can be used.

Advantages of Integrated tanks

  • A lot of cost and expense goes to installing the conventional solar collectors and installing separate tanks and heat exchanger - this eliminates most of the costs.


  • 

There are a few different types of these tank / evacuated tube systems.

  • They have an integrated tank built into the system so you dont need to buy separate tanks or heat exchanger which can save you thousands of $$$

  • Non pressurised means is that the tank is full of water which gets heated by the sun and then gravity is used to supply the hot water from the tank into your home / cabin / workshop etc.

Things you should know about the IT300 -HP-HX Model

This version DOES include heat pipe in the solar evacuated tubes. It does cost a bit more money but is a bigger more versaitle model.

The water fills the tank BUT DOES NOT fill the glass solar tubes. The tubes get heated by the sun and the heat pipes can reach temperatures of over 250 Degrees C.

As the tubes do NOT fill with water this IT300-HP-HX model is suited to Summer use but can also be used in colder climates so long as steps are taken to prevent freezing of the lines to and from the tank.
In addition you will need to add the electronic controller to control the back up electrical heater which will keep the tank warm enough so as to not freeze.

This model is ideal for offgrid cabins and homes, camp sites.

These are the SAME tubes as in the L51S-30, L51S-20 collectors.

Gravity and Mains Pressure

As the tank is non pressurised (ie the tank is not designed to hold main water pressure) once the tank is hot, water needs to flow DOWNHILL into the cabin. This means the IT300 needs to be installed ABOVE the shower or tap or where ever you want to allow the hot water from the tank to drain into the building.

Normally this means it has to be installed on roof of the building.

However as this model also includes a built in copper coil heat exchanger you can connect the mains pressure water to the coil. This means the tank and collectors can sit on the ground outside a cabin or swimming pool. The water pressure of the mains pushes water through the coil where it is warmed by the hot water in the tank. In this case you are not actually using the water in the tank, just the heat stored in the water.

Obviously you can use a combination of these, mount the system on the roof, drain hot water by gravity or use the mains pressure coil all at the same time.

"This product may contain nuts" - A word of warning?

The tubes and tank and frame on their own weigh about 110 kgs (140 lbs). However the tank hold 300 litres of water. 300 litres of water weights 300 kgs (440 lbs)

So one of these on your roof will weight about 410 kgs / 902 lbs.

Although this is a lot of weight, it is normally not an issue for most roofs if they are in good condition. To put it into context, this is like 4 large adults standing on a roof.

The world we live in now is full of rules such as where bags of Peanuts come with labels saying "this product may contain nuts" We have these rules and labels because the world is full of people with peanut allergies who will eat a bag of peanuts then send in the lawyers.

The same applies to all solar collectors. While we say above most roof should be OK to install one of these solar collectors, the person installing the system is FULLY responsible for verifying the condition of the roof prior to installing the solar collector. They must confirm if the roof will support the weight of the solar collector and solar tank when full of water.

If in doubt call a roofing contractor to inspect your roof and let you know if its OK BEFORE starting work.

If you buy this and install it on your roof and the roof collapses - IT is your own fault!


If you want to think about installing an integrated tank system in colder climates you will need the IT300-HP-HX

A heat pipe is used in collectors designed to produce huge amounts of heat in very cold climates and as the glass tube has no water in it

Do you need a system to install in Colder climates?
The IT300 - HP - HX can be used in colder climates but take needs to be taken to insulate the supply and return lines and add additional back up trace heating to the lines to lines to ensure nothing freezes

Filling the Tank

The Assistant tank is the little white tank shown in the photo below.



The assistant tank site on the top of the tank and controls the filling of the tank.


This diagram is showing the IT300-HP-HX tank (with the internal heat exchanger) however the Assistant tank can be seen on the top right corner.

This is a manual valve that stops the tank overflowing. If you want a simple system with no electronics, then select the "Assistant Tank" from the options above. Its basically a ball valve system to stop the tank filling up if it is already full of water, see image below.

Solar water heating tanks - integrated solar tanks


CSA Certification
Please note, although the tubes and heat pipe in these collectors are exactly the same as our other models of collectors that conform to CSA F378, these integrated tank models are not "csa certified". Don't ask us to explain the rules, we didnt make them and the staggering cost that is imposed to get this certification is not on the cards just now....!
