In a utility room about 4.5 feet wide I have my hot water heater. The electrical plug and dryer vent require the use of a stackable that would sit right next to the water heater by about 6 inches. The electrical outlet is right in the middle of the 2. Would it be safe to install an electric washer dryer stack next to the GAS water heater? My husband has been leery of it so up to this point I do not have one! Please help?
