5 Common Problems with Hot Water Systems

Do you encounter problems associated with your hot water system? You definitely need some repair and help from experts when necessary.

Hot water heating systems make use of heater or boiler-heated water as their heating medium that is circulated to baseboard radiators or convectors. Issues here may include, but not limited to insufficient hot water supply, too hot water and smelly water from the tank. These heater issues usually become self-evident. Learn more about heater problems and their solutions.

Hot Water Heating System

Hot water heating systems come in two types, namely gravity and forced. It is noted that gravity systems do not have water pump, heat unevenly and require larger pumps. They are oftentimes replaced when renovation is being done. Forced water systems are heated by oil-fired or gas-fired boilers, but it is best to use electric resistance heating coils rather than burners in the boiling system. Oil- and gas-fired water heaters use distribution piping and hot water pumps with series-loop or pipe systems.

Problems here may occur in various parts of the water heater such as hydronic furnace or water heater, boiler controls, boiler, expansion tank, radiators and distribution piping. Certified plumbers or technicians should carry out repairs for these issues.

Expansion Tanks

Take note that expansion tanks are being installed near your boiler for water expansion and contraction as temperature changes. The problem is attributable to lost air in the tank, making the unit waterlogged thus preventing its expansion. The water is discharged from the pressure relief valve of the boiler. You will need the service of a professional plumber for your expansion tank to be drained and re-pressurized.

Boiler Controls

All boilers are expected to have pressure relief valve, pressure-reducing valve and a pressure gauge. There are boiler controls equipped with circulating pump and controls and high temperature limit control. Your pressure valve may be faulty if the pressure readings are 12 psi and lower. This then indicates the necessity for the unit to be replaced or adjusted. Water heater coil crack is another factor for waterlogged boilers. An aquastat needs to be installed, replaced or checked when the boiler becomes too hot. It is recommended to listen for loud pump operation, which may indicate a faulty motor.

Distribution Piping

Radiators, control valves and pipes transport the hot water coming from your heater. You need to check the connections and valves for leaks in distribution piping. Pipes must be insulated in unheated sections like attics, basements and crawl spaces. The fins of the heating system should be inspected for any damage or dirt. The air that is trapped inside the unit has to be discharged in the event the radiators failed to warm up evenly.

Insufficient Hot Water

When you don’t have enough hot water supply in your home, most likely undersized water heating system is the cause. This issue can be repaired, but there will be a need for installing a larger heating system if you need high-flow shower head or soaking tub.

These are just a few of the problems you should deal with properly to avoid inconveniences in your hot water use.
