Can you turn the heat on, take a shower, turn the dishwasher on and do the laundry at the same time.
If you can, I am very much interested in the details of your heating system.

I installed the Rannai E-Series condensing boiler. I believe there is about a $1500 energy rebate on the boiler. And possibly more from NHsaves.
I have natural gas at my home, but they are available for propane as well. One nice feature I like, when I am away and the temperature is below freezing, you can set it up so that the pump is running continuously to prevent frozen pipes in your heating system. A nice feature to have when you lower the temperature to save energy.
Make sure you read the owner's manual about setting up your room thermostat. A condensing boiler is programmed to learn to send only enough heat to the building to compensate for the outside temperature. The anticipation should be 1 degree or less.
And yes, I can have two showers going, with the dishwasher and or laundry going at the same time.
I did research and found I save about 70% in gas for my hot water. I had a 10-year-old 60 gallon NG hot water heater. I also save about 30% in my home heating. I had a 30-year-old Celtic boiler.
