Richard gives a tutorial on how new water heater regulations will affect homeowners.

Richard explained the new federal regulations that affect the energy consumption of home water heaters.

All tank style water heaters may increase in size due to added insulation.

Additional information on the new regulations can be found from the Department of Energy [https://bit.ly/35dnGdh].

Key points:
1. Small-capacity gas-fired water heaters, in the 30-gallon to 50-gallon range, must now have at least 2 inches of insulation on the sidewalls of the tank and 2 to 4 inches at the top of the tank.
2. Gas-fired water heaters with 55-gallon or larger tanks can no longer be vented into a chimney.
3. New condensing water heaters must be connected to a PVC vent and direct-vented to the outdoors.
4. The new electric-powered water heaters with 55-gallon and larger tanks will be hybrid heat pumps that use 50 percent less energy but are much larger and taller than previous units.
5. The new regulations don't affect on-demand tankless water heaters.
