Tried the new Rheem out this morning
well it was 40 degs here this am so I tried the new furnace. I was impressed that the temp of the air coming out of the register was as hot as it was. Everyone told me it would be much cooler than my old oil furnace. It seems hotter !
I checked it with a digital thermometer in the reg and it was 130 degs . Now this was with the furnace in second stage because the t-stat said the room temp was 64 and I set it at 70.
Seems to have performed great now lets see when it is below zero out
THIS MEANS YOU HAVE A 66 DEGREE TEMP DIFFERENCE OR(DELTA T) IF YOU LOOK INSIDE YOUR FURNACE AT THE DATA PLATE IT WILL TELL YOU WHAT THE TEMP DIFFERENCE SHOULD BE, THAT WILL TELL YOU IF THE FURNACE IS OPERATING PROPERLY
Hotter is not better; the greater the temperature rise is, the less efficiently the heat exchanger can transfer heat from the combustion gasses to the indoor air. Life span can also be reduced.
66F is probably on the high end of the specified range - check the dataplate.
economic collapse is a certainty. debt based fiat currency monetary systems can never continue indefinitely because they require continuous creation of new debt to service the existing debt. in the absence of economical growth (which is always predicated on increased resource extraction rather than capital alone), this leads to massive inflation which destroys the currency.
your leaders can't fix this - they're corrupt and only exist to enrich themselves and their corporate friends.
ok plate says hi fire 40-70f low fire 30-60 does this make sense ?? It was in the hi fire mode and the temp was taken at the register right above the furnace in the living area.
Is this ok or do i need to call them back and have it adjusted ????
The 66 DEGREE Temp split is between 40-70, so your ok. Just means air flow is slightly low. Depending on the blower, you may be able to increase the speed, but you may get a noisy unit.

hope the filter dont get dirty, also with a high temp rise it tends to dry out the house more
It has the thicker 4" filter in it. I had the register in the basement closed would it help to open that reg ??
I wouldn't mind it drying the house out some as it tends to be kinda humid in the winter anyway not real bad though.
Is there a way they can change that temp rise easy ?? I know the fan was running at hi speed because when it only needs to go up like one deg in temp the fan is slower.
If left at this temp rise would it do harm or really cu my efficiency ?? If so shouldnt I call them ??
If the fan is already in hi that probably cant be chgd then right ??
depends on the system. could be variable speed in which case cfm can be adjusted or you may have three or four speed taps. high speed is usually reserved for cooling
its a rheem RGRL I believe it is a 2 stage 2 speed blower ??? Where is twilli when I need him
Temp rise has no effect on the humidity.

Open the basement return, it will help to lower temp rise, to a safer level.

There are lots of cold air returns up stairs though
Return is the air drawn into the furnace.
In heat mode, its the cold air.
I'd still open the supply in the basement. It will help lower the temp rise, by lowering your supply static.
