Todd Paternoster goes over selecting a solar thermal storage tank for your system.
Reducing fuel bills and increasing solar thermal output
Q: What is the best way to reduce my fuel bills by incorporating a solar thermal system? A:Reduction +Reduction = Reduction This should come at no surprise to any of our readers but the single best way to save money on energy bills is by reducing your consumption. It is surprising to...
How can I simulate the performance of my solar thermal system?
Q: What is the best way to use a computer simulation model for my solar thermal system? A: There are many types of software that help determine the energy output of solar thermal systems. We use Polysun Simulation Software, professional version. With this software we can effectively design small to...
Setting your solar thermal system differential temperature setpoint.
Q:What is the most appropriate differential temperature for my solar thermal system? A: The factory setting on our controllers is 12 Degrees. This will work fine but for northern climates it is better to have a delta T of 17 Degrees. This will allow the collector to heat up sufficiently so...
Keeping propylene glycol from freezing in my solar thermal system.
A: How do I prevent my glycol from freezing during those rare deep freeze nights? Q: Your glycol, although rated for very low temperatures may be un-pumpable at a temperature higher than you expect. This can cause you system to overheat when the sun comes out in the morning. To prevent...
How do I determine the most appropriate solar thermal storage size?
Q: How to determine the best solar thermal storage size. A: Choosing your storage tank size is dependent on three things. 1- the number of ft2 of collector- for example we typically recommend any where from 1-3 gallons of storage per ft2 of collector, 2- the daily load profile (usage...
