TANKLESS WATER HEATERSTankless water heaters are becoming a popular, energy-efficient replacement for standard tank-type heater. When installing a tankless water heater there are many things to consider.

The following items will need to be provided to the inspector at the time of the initial water heater inspection:

Manufacturer’s installation instructions often require special venting materials and specific installation practices.

Most installations require larger combustion air openings/ducts to be installed.

Typical tankless water heater gas demands require gas pipe sizes to be significantlyincreased or additional dedicated piping, from the gas meter to the water heater, to be installed.

Water heater and venting material manufacturers’ installation instructions.Calculations/drawings for the increased gas demand.

1. Mechanical equipment such as air-condition units, utility meters, transformers, water heaters, satellite dishes, etc. may not be located on the front elevation.

2. On new homes or when additions are proposed, water heaters should be located within a building's foot print.

3. Water heater enclosures are discouraged. When used, enclosures should be architecturally compatible with the primary structure and fully enclosed.

4. Solar panels should not directly face to the street and should be installed in recesses into the roof structure whenever possible. Solar panels should be fully integrated into the roof structure.

5. When possible, consider the installation of solar panels on accessory structures, patios or ground mounted in the rear yard, away from the public view.

Figure 6-49: Locate accessory structures to the rear of a property
