Hydronic Baseboards Not Heating Properly? Check Your Gas Water Heater For Problems

Construction & Contractors Blog

If your hydronic baseboard heating system suddenly develops problems, such as not putting out warm air or taking too long to heat up, check your gas-powered water heater. The heating system depends on the water heater to create ongoing hot water during the winter months. Sometimes, sediments form inside the water heater, which prevent the appliance from sending out hot water. If hot water doesn't reach your hydronic baseboards on time or properly, they can't heat your home. Here's how your water heater affects your hydronic baseboard system and tips to solve the problems fast.

How Does the Water Heater Develop Problems?

Gas water heaters develop mineral sediments over time. If too many sediments build up inside the water heater, they settle at the bottom of the appliance until they eventually clog up the pressure valve attached to it. The excessive pressure prevents the water inside the water heater from traveling through the baseboard heaters' supply lines.

One of the ways to tell if you have water heater has too much pressure from excess sediments is to examine the flow of hot water coming out of your taps. If the water drips or trickles when you use your taps, calcium, phosphates and other mineral sediments plug up the water heater's drainage or flush valve. A clogged valve increases the pressure inside the water heater and its lines because it can't release it properly.

Draining the valves lowers the water heater's pressure and removes excess mineral deposits from the appliance, as well as supplies your hydronic baseboards heaters with hot water. 

How Do You Drain the Water Heater?

You drain the water heater by following the tips below: 

  • Turn the water heater's thermostat or temperature setting to below 125 degrees Fahrenheit, then wait 45 minutes to an hour for the appliance to cool down. You don't want to handle very hot water, which can burn and injure you.
  • Turn off the water heater's gas supplies. You don't want to create a dangerous gas leak in the home if you accidentally hit the gas valve or puncture the appliance.
  • Place a towel beneath the drainage valve, which is located on the bottom of the appliance.
  • Position a wide pan beneath the valve to contain spills. You can use a long baking pan if you don't have anything else to hold the water.
  • Turn the drainage valve to release the water and sediments.
  • Stay a safe distance away from the flowing water, as it can still be hot enough to burn your skin and eyes.

After you empty the water heater, close the valve and pour the sediments and water outdoors. Don't pour the contents down your sink drains or toilet, as they can clog up your plumbing system.

Switch on the water heater's power, then wait 20-30 minutes for the water to heat up and the baseboards to operate properly. Also, check your faucet taps to see if the water flows freely now. If the taps and baseboard heaters operate correctly, you successfully fixed the issue. If not, contact a local water heater specialist (click here for more info) for services.
