Please excuse my ignorance, but could anyone please explain "what"
makes the Buderus boiler's water gauge temp go up? I'm trying to understand why we come home every evening to a cold family room (on slab - with own thermostat), turn temp up, and it could be hours before the 20 x 16 room heats 3 or 4 degrees. That gauge on boiler is usually reading around 120 degrees.
Yet in the a.m. that gauge is around 150 degrees. Have been told that the water needs to heat up as quickly as possible in order for the room to heat up. Makes sense. But at night, nothin' seems to make that gauge go as high as during the daytime. One suggestion is to install higher output radiators in family room.
Have had 3 different HVAC guys say the system is fine.
Also have a Buderus indirect water heater.
If anyone can explain in simple layman terms, "why" this gauge
seems to be so low in the evenings, as compared to daytime, I'd be most appreciative. Am just trying to understand how the boiler "works". System has the Logomatic, & its set to "winter mode" right now).
