Ivan, thank you so much, that means a lot! I'm happy I could provide you with some Messana insights in an engaging way. Let us know if you ever have any questions regarding our system! - Saul
We'd certainly like to work on a project out there! One thing to keep in mind in that type of environment is the consistently high humidity level. With high humidity comes a high dew point temperature, which inhibits radiant cooling performance. The dew point is the point at which condensations forms and we must keep the radiant surface temperature above that point at all times during cooling. So if you have a high dew point, you will need to use warmer water in cooling, limiting cooling output. To get around this, dehumidification units can be incorporated and managed via Messana Controls. This lowers the dew point in the environment to allow for more effective cooling. Another option we recommend is the incorporation of hydronic fan coils. Hydronic fan coils utilize the same supply and return hydronic lines that feed our radiant panels. Because of this, they don't require ducting and can be managed via Messana Controls. We tend to recommend Jaga hydronic fan coils which integrate particularly well with Messana Controls. Using our hydronic controller, we can power Jaga's low-voltage fan coils directly as well as provide some dehumidification to assist the radiant system. By running the fan coil with chilled water at a low fan speed, we can produce condensation which is then collected by the fan coil condensate drain. By creating condensation using the fan coil, we pull moisture out of the air to lower the dew point temperature in the environment, allowing for greater cooling output.
@@messanatech oh wow. i didn't think about that at all. such a great point. you've obviously thought about it a lot! thank you for your help. I'll take this back into discussions!
I heard you mentioned in multiple videos about low thermal mass for cooling. I live in the tropics. Hot all year round. What if I want the thermal mass because I don't expect to ever need heating, is that possible?
Humid environments like the tropics are actually where a low thermal mass is critical! A low thermal mass results in a faster response time, allowing the panels to quickly react when there are changes in the humidity and the dew point temperature (when condensation forms). So if anything, it would be the opposite, where a high mass system is okay for heating-only, although it will be less efficient because it will require higher water temperatures to be brought up to temp (this makes the energy source work harder).
Hi there, great question! Since radiant cooling output is limited by the dew point temperature, they excel in dry climates but may be limited in humid climates. So a radiant cooling system in a dry climate like St. George would do well. With that said, however, it is typically a good idea to incorporate a second-stage cooling system for the hottest days of the year. We recommend using Jaga hydronic fan coils that can tie in directly to our hydronic system/controls. This is useful for homes with large doors that open to the outdoors. Once they are closed, a radiant system would take longer to bring the environment to its set point, so having fan coil units would speed up that process. By utilizing fan coil units, you'll have a quick way to bring your environment to the set point and the radiant system can take over from there.
This sales rep is excellent. Great enthusiasm, knowledge, and people skills. Good job grabbing leads and not being too aggressive.

OUTSTANDING : o .....
this is very good. you guys need to work on expanding into the caribbean market!!! very different style of construction to the us, but much hotter!!

Can this cool in extreme heat? I am in St. George Utah and the temp today is 118 Fahrenheit (think Vegas sun + heat).
