Hot water heating systems require some maintenance, including draining the boiler and venting the radiators to ensure things are running efficiently.
- Lubricate the circulating pump motor on your boiler. Use a lightweight oil, as per your boiler owner’s manual and pour it in the oil cup.
- In the fall and throughout the season of use, you need to vent or purge radiators if they do not already have an automatic purge system.
- After purging make sure pressure levels are ok. You can find out what pressure level is recommended by the boiler manufacturer in the operating manual. You then let out the air in each convector, if needed, until the pressure is at the recommended operating level.
Hot Water Tank Maintenance
Establish a maintenance program to extend the life of your water heater. Most water heater failures are due to lime/sediment buildup, excessive pressure or corrosion.
To Reduce Lime/Sediment Buildup (Every 6 Months):
- Drain the tank through the drain valve until the water is clear.
- Inspect the tank for lime or sediment deposit either through the nipples or through the clean-out hole.
- Remove lime, scale or sediment using care not to damage the glass lining of the tank.
- Inspect the anode rod and replace as needed. Anode rods are designed to attract corrosive elements in the water and thereby diminish corrosion of your tank.
To Assure Relief Valve Operation (Every 12 Months):
Manually open the relief valve to flush any lime deposits that may have developed. Caution! Water can be extremely hot. Make certain the seat closes properly. Let it snap shut.
