How to fill in the description of almost identical products?

I am making a solid fuel boiler shop. There was a question about filling in the description and the Meta-tag "description"
In fact, the boilers are the same, they differ only in the power figure and the heating area, you cannot write a unique description for each.
How to do in this case more correctly? Write one for all boilers and add a description to each model or do not fill it out at all? Only one per category page.

Answer 1

Write the same description in each model, the model code must be present everywhere. It will be the root difference of the goods.

Answer 2

There is another option (complex and hemorrhagic).
A technical description (which will almost completely be duplicates on different pages) can be made in the form of a picture. Then the text will not be read as a double.
In order for there to be some kind of promotion under the bass, write in text what can be unique + add reviews on the page. It’s hard for me to say how much your product induces to leave reviews (this is not an electronics or clothes store), so I don’t know if this option is right for you)
