Hi,
Should a Navien hydronic heating system turn on and off four to five times an hour?
I am living in a place with a Navien CH-240 that drives domestic hot water and an in-floor, six-zone hydronic heating system. The hydronic system uses PEX tubes under a concrete floor. I have only ever had forced air and typical water tank heaters before.
Now, I am used to having one thermostat in the home, and programming it to have different behaviors at night, morning, away at work, and evening. You know, typical stuff. But it seems that this system I am living with now is... different.
Each zone has an Uponor thermostat wired to the main control panel near the Navien. If I set one zone to, say 70, then when the temperature drops to 69 I hear the thermostat "click," the Navien kick on, loud at first, then low hum for a while, the floor gets warmer, the temperature rises in the room, the thermostat "clicks" off, and I hear the Navien do it's last loud thing and then go quiet / off.
Ok, the problem is, some nights I hear the thermostat "click" on and Navien spin up, and then "click" off, and then on and then off. Is that normal? Especially at night, this happens for many hours and is a little annoying. But more importantly, it's like the Navien is burning gas and electricity all night.... shouldn't it be, I don't know, "smarter"? My gas and electric bills certainly don't seem any less than normal (but I don't really know).
Because of this annoyance, I usually only warm one or two zones and leave the rest at around 65 so they too don't click on and off all night.
Is it better for me to set all of these thermostats at a higher temperature than what I normally would with a forced air system?
Is it better to keep them at a constant temperature, like 70, rather than trying to turn things down at night or before I leave home for the day, like I would with a schedulable forced-air thermostat?
Should I raise the temperature of the hydronic water so that it releases more heat in the floor, longer?
Thanks for any insights and tips... I am not sure I am explaining why this system confuses me as it does.
