Yes, you sure can. There are very few systems in the US that will not accept a solar thermal upgrade, The only exception would be a steam system. Whether you have forced hot air, boiler with baseboard, sub-floor radiant, in-floor radiant or wall heaters you can very easily integrate a...
Solar thermal systems will behave differently depending on a few variables such as, the obvious, location but also angle of tilt (slope off horizon), orientation angle, temperature of inlet fluid and also daily ambient temperature. We can calculate the efficiency of collectors for various times throughout the day but given the...
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...
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...
Question: How do I remove air from my system? Answer: Take a deep breath and let all your air out… of your Solar thermal system One of the biggest issues with a successful commissioning is air removal. Any time you spend with this detail will be time well spent. Air pockets become entrained...
Question: Do I need to use glycol if I live in an area where I only have a few days of freezing per year? Answer: If you live in an area that doesn't get below freezing often (less than 5 days per year) it is possible to get away with using water instead...
