Heating reset - resetting the heating water temp down, as the load drops. this reduces piping heat losses and improves control.

Tankless Water Heater?
On-demand heating is good for small apartments and households that have low/infrequent demand for hot water. May require larger gas line to provide adequate speed for effective water heating, however, it eliminates the need for a reserve tank that is maintained at a preset temperature.
Why use a programmable thermostat?
Turning back your thermostat during the day, when no one is home and at night, when there are few factors changing the indoor temp, makes sense if you have a leaky house in which the heater seems to always be working to maintain the preset temperature. Our house is very leaky, so the heater will continue cycling on and off trying to maintain the set temperature throughout the day and night. If we had a well insulated house it would be understandable to set the thermostat at a reasonable (agreed upon) temp satisfying everyone in the house. It would make sense to leave it at the set temperature because, with minimal heat losses to infiltration and conduction through windows and insulation gaps, the heater does not have to cycle on and off that often.
Radiant or Radiator heating over Electric Baseboard:
Electric baseboard is inherently inefficient and wasteful because the energy source has a 'double-taxation' of efficiency losses to it. The electricity is created at the powerful from a fuel burning process that has power losses associated with it. The electricity then travels through Transmission & Distribution lines to the plug of your baseboard heater. Here the electricity is converted into heat energy through an additionally inefficient process. Radiant heating burns fuel directly in a furnace to heat water that is cycled through pipes in your home. Another benefit of radiant floor heating is its ability to make rooms 'feel' warmer, by heating typically cold wood or concrete surfaces that people touch directly. Therefore, the comfortable temperature setting of radiant floor heating is typically lower than that of a forced air or baseboard heated space
