While most homes use a furnace or other HVAC system for heating purposes, some older homes use a boiler. A boiler is an effective way to heat a whole house; however, boilers can have issues just like any other type of appliance in the home. If your boiler doesn't operate as it should, your home can become susceptible to not having a heating source or you could cause damage to your property with a faulty appliance.
Your plumber who is skilled in boiler repair services can take care of your heating unit and make sure it's running as it should. Here are signs your boiler needs repairs.
Your unit doesn't heat reliably
Your boiler should provide consistent heat based on the temperature settings you have for your home. If your boiler is relaying insufficient heat or uneven heating, your home can have a hard time keeping warm for longer periods of time. Have your plumber check both your boiler and the thermostat to see what's going on so you can have more reliable heat.
Your unit is using more energy than usual
In addition to having poor heating, your boiler may be using more energy if it's not working as it should. This could be related to a failing unit sucking more energy to stay running or be from more energy being used to turn the unit back on again if your boiler shuts off a lot. If you've noticed your energy bill being higher than usual, then your boiler may be wearing out and it may be time to replace or repair the unit.
Your unit blows cold or warm air
Your boiler should not blow cold air unless you have your thermostat set at its lowest setting, and even then, the air should still be warm enough to be slightly comfortable. Cold air emissions is a sign that the boiler isn't heating up properly, which means the heating element may be failing or the boiler is otherwise unable to supply warm air.
Since a boiler that blows cold air is not only not keeping your house warm but is also using up valuable energy, it's best to shut off your unit until you can get your plumber to look at your boiler. If your appliance hasn't been inspected in the last few years, it's time to have an inspection done to check for any needed repairs that can be done on-site when your plumber is there.
