Boiler Repair questions, answered by experts

Not every type of baseboard heater needs to be bled. Hydronic baseboard heaters need to have air removed at least occasionally, but electric or gas versions that don’t use water at all don’t need to be bled. There are no pipes or valves on these models to worry about, nor any central boiler. Instead, they use heating elements or other methods to supply direct heat to a room.

If you hear your radiator clanking even when it’s turned off, it’s typically because there’s trapped water or air in the system, causing a pressure buildup. When you hear significant clanking, popping, crackling, or banging in a radiator that’s turned off, you’ll want to bleed the pipes or call in an HVAC specialist to deal with the problem (and prevent it from happening in the future).

To maintain a boiler and ensure it works optimally, regularly read the temperature and pressure gauges on the unit to ensure they're within the limits described in your owner's manual. Lubricate the circulating pump according to the manufacturer's instructions. Check the water level in the expansion tank and open the tank valve to drain it if it's more than half full.

No, there isn’t always water in radiators. In a one-pipe system, water is constantly circulating from the boiler to the radiators and back. In a two-pipe system, water travels through two separate channels: one that goes to your radiators and one that returns back to the boiler so it can heat up again.

Blockages can occur for various reasons, primarily linked to the accumulation of debris or substances within the heating system. Common causes include the buildup of sediment, rust, or mineral deposits inside the boiler or its pipes, hindering water flow and heat transfer. Additionally, air pockets or trapped gasses can impede circulation. In central heating systems, sludge or corrosion within radiators can obstruct the flow of hot water. External factors like frozen pipes in winter can also lead to blockages. Regular maintenance will help prevent blockages and ensure efficient boiler operation.
