In order to achieve this, it is necessary to have a series of zones that are controlled by energy regulators. Ceramics do have some disadvantage in that their high thermal mass makes them slow to warm up (approx 15 minutes) and slow in their response time when adjustments are made.
I love it as a get started cheap method. like you said if you find you want more better capability then you can justify spending more money and time to build a better one.
When is the time right to make the upgrade from molded fiberglass to thermoformed plastic? There are several factors to consider.
