Residential Hot Water Boiler Repair Residential Hot Water Boiler Repair

A hot water boiler can prove to be an excellent gadget during the winter months when hot water is needed quickly. However, like many appliances around the house, hot water boilers tend to need regular maintenance and upkeep to keep them running smoothly. Most users face problems as repairs need to be performed often. While hot water boilers are not very easy to fix they can be handled at home with the correct know-how. Being able to repair a hot water boiler at home needs accurate guidance and practice.

Why do Problems with Hot Water Boilers Arise?

Hot water boilers on the whole are reliable appliances that can run for a number of years without giving much cause for trouble. However, once they begin to get old, boilers usually tend to throw up some standard troubles that are common to most styles and makes. These problems usually result due to wear and tear of the circulator, the pressure reducing valve and the expansion tank instead of problems with the actual boiling device itself. Other than that, hot water boilers have very few problems because the number of mechanical components in these appliances is minimal as compared to other home appliances.

Diagnostics

Before any troubleshooting can be done, a quick diagnostics test needs to be run to figure out where the problem is. The following symptoms indicate the boiler needs to be repaired:

  • If the pipes of the boiler begin producing a loud clanging noise: This is a sign of problems in the circulator of the hot water boiler. Circulators usually need to be attended to by professionals and can be best repaired by trained service providers.
  • If the unit fails to produce the required degree of heat: When this happens, adjust the thermostat to different settings and also try inspecting the fuses, the circuit breakers, the safety controls and the switches.
  • The heating system pipe may start having water leaks: These one can be fixed yourself following a manual. Water leaks are usually detected when the system does not heat the water correctly.
  • If the cooling units of the hot water boiler begin to expel or ‘bleed’ air while some radiators warm up and the others don’t, it is generally a sign of damage in the circulator.

Quick Troubleshooting Tips

  • The pressure control valve of the boiler often needs adjusting. If your boiler is gushing out water rapidly, it is an indication of excess levels of water and a lack of air in the boiler. This can be fixed by opening the drain cock and vents and then closing them until the pressure reaches 20 psi.
  • Make sure the valves are all turned to the standard settings. If even after this the readings on the combination gauge fail to return to an optimal position, you should call a professional.
  • Sometimes air gets trapped in the boiler for which the vent needs to be opened gently with a screwdriver or tool supplied with the boiler. When the air escapes and water starts coming out, close the vent.
