In our first stage of our prototype we were able to build a very basic and rudementatry version of what our end goal would be.  Althought this prototype was quite successful at protatying the basic logic behind the theory of our project it was not a functional prototype with no real testing ability  due to the lack of real world variable such as underground and ambience temperature,as well as how would the system behave inside of a real house with insulation and other factors.  Which is why the creation of a second stage prototype was required.

In our second stage of our prototype we decided to simulate the conditions as similar as possible to that of a normal building.  Which is why we decided to create a design  as similar to that of a house as possible but only in minature.  We also ensure to use  materials that are used in the construction of homes such as drywall and insulation in order to make this prototype as functional as possible.  The end result of this was not onlya functional system in which we  can run water through but also a functional prototype from which  we can gather useful  data that assimilates as much as possible to the real world.
