Hello everyone,
A brief overview of our situation. We are currently planning our single-family house (approx. 250m² living space) and will use a wood gasifier stove + solar thermal system for heating. I currently assume that our future buffer tank will be about 5,000 liters in size, which gives me the advantage of not having to fire up every day and to be able to store energy with a suitably designed solar thermal system.
With the size of the buffer tank, one is rather an exception and entering new territory for some heating engineers. What I keep coming across are non-pressurized plastic buffer tanks. The advantages seem to be the easy installation even in existing buildings (not relevant for me as it is a new build) as well as the lower thermal conductivity of plastic compared to steel.
Has anyone here already thought along the same lines? What are the actual advantages and disadvantages of a non-pressurized plastic tank compared to a steel tank of this size?
Thank you very much and greetings from BaWü
