This is normal for a car. This occurs because the engine has to work a little harder to pump up the heat, and this results in higher RPM.

What causes a vehicle's RPMs to rev up while driving?
If you accelerate and the transmission shifts to a lower gear of the overdrive disengages the RPMs will increase. If the vehicle has a manual transmission a slipping clutch will cause the RPMs to increase if the clutch is defective.
Why would a 96 Taurus wagon heater only blow when running at high RPMs and cool down when idling?
it has a partially clogged heater core.replace the heater core
1990 Mazda Miata - Does the AC Switch when turned on supposed to increases the RPMs?
Yes, at idle it brings the normal stock of 900 up to 1000 rpms
Why does my car heater only work when the rpms are high?
The first thing that you need to check will be the coolant level..................
What does it mean when RPMs increase but no speed?
Your car or vehicle is in neutral, or the clutch is shot.
Can you go in a pool with the heater turned on?
Yes.
Does a new heater burn your eyes when turned on?
No.
Why does the engine surge when you turn on the heater?
The most likely reason would be because you also have the defroster turned on with your heater. The defroster causes the A/C compressor to kick on which helps remove extra moisture in the air keeping your windows from fogging. The A/C compressor is linked to a "kick up" that brings the RPMs up to keep your engine from stalling due to the extra load possibly causing a surge.
What is the problem with a 1998 911 Carrera if the RPMs are revving up unusually high when you hit the accelerator?
Perhaps you have not engaged the clutch? The accelerator is designed to increase the RPMs. If you provide no resistance it will rev until it explodes.
Would water heater lite if gas was turned off?
No.
How do you increase boiler efficiency?
we can increase boiler efficiency by recovering the heat which is being carried by flue gases.by incorporating different things like Economizer, Air pre-heater , Super-heater and feed-water heater, we can there ll be notable increase in efficiency of boiler.
What could be causing a 2005 grand prix with 14000 kms to have ticking sound that does not increase with RPMs it seems worse when engine is warm and poor performance especially at low speeds and RPMs?
VALVE LIFTERS... the fact that the ticking does not increase with rpms rules out valve tapping or worn piston pin but is indicative of the bearings going bad in the water pump which also would explain the loss of performance.
