WFH and need option to heat a single room vs HVAC
1- Bridge the furnace control board jumpers to run the fan on low 24/7 and when Ecobee calls for heat.
The board accommodates this by default, and currently calls for heat on medium and for AC on high. This has the advantage to circulate the air continuously and equalize ambient temperature in all the rooms. It will cost in electricity bills though, and I have already seen a significant rise on my usage and bill since April.
2 - Set a temporary set point when it's cold.
This is my do nothing approach, and deal with the issue as needed. Not my preferred option, and it's a waste to heat the whole house, to get one room to temperature. We do this in the summer for AC, but that's another story.
3- Use a space heater.
I already have an infrared space heater, that was used very infrequently, it's 2500w of heat on high and 1500w on low. It has a thermostat, so I can just plug it in and leave it alone, but still don't trust to leave it when not around the desk area.
Now, what do our board HVAC experts think is the best option, or is there another option that I may not know off?
Thanks for any help.
