How to Recharge a Hot Water Heating System

Recharging hot water heating systems is more convenient than draining water from a tank. Recharging your hot water heating system will recharge hot water and replace heat lost through the walls, a roof and windows. A typical cycle to recharge and boost hot water back to its recommended gauge takes almost three hours. Recharging is most efficient in the morning because it takes less time.

Things You'll Need

• Regular Tire Pressure Gauge
• Bicycle Pump
• Compressor

Instructions

Instructions

1. Attach a regular tire-pressure gauge, used to measure the pressure of air, to the recharge valve, usually located on the underside of the tank.

2. Using the attached tire pressure gauge, check the air pressure in the chamber.

3. Use a bicycle pump or compressor to add air until the gauge indicates that you have reached the tank's recommended pressure.

Tips & Warnings

• If your heating system requires constant recharging, there's a possibility that your tank is leaking and may need to be replaced.
