It is also a high Propane demand device just like your furnace. If it works with the cooktop and oven on AND the fridge (in Propane mode) all on at the same time your regulator is likely good.
Remember, you have two regulators. One on each Propane tank. If you suspect one is bad switch to the other one by turning off the suspect Propane tank.

The water heater consumes at most 10,000 btuh assuming it's not tankless. The furnace consumes at least 30,000 btuh. The advice recommending checking with all the other gas appliances running, assuming you don't have a monometer, is spot on.
The regulator on the door side is a high pressure regulator. It feeds gas to the low pressure on the off door side. If the high pressure regulator is bad, it will only impact things when pulling off that tank. If the low pressure regulator is bad, it will impact things regardless which tank it's pulling from.
FWIW a monometer is a great tool to diagnose problems with gas pressure. A water filled U tube manometer is the least expensive, but still accurate. A digital is more accurate and somewhat more convenient to use. When you test the gas pressure check static pressure first. That's with nothing on. Then turn on everything and check again. It should be between 11"-14"WC in either case.
