Is Your Fireplace Not Giving Enough Heat? - Centereach NY - Dunrite Chimney (1)

The allure of a cozy fireplace or wood stove when the weather is chilly is undeniable. But if your fireplace isn’t producing the warmth you expect, it may be a source of frustration, rather than comfort. Fortunately, understanding some potential reasons behind your lack of fireplace heat can help you identify and implement appropriate solutions to reignite the cozy ambiance you crave.

Why Isn’t My Fireplace Heating Well?

There are a number of potential causes when your fireplace isn’t generating the heat output you think it should. From airflow to insulation to fueling to design, assessing whether you’re getting the most from your fireplace unit is a great first step to maximizing its efficiency.

Poor draft. It’s a well known fact that fires need oxygen to thrive. Adequate airflow is imperative to the combustion process, so it makes good sense that inadequate air flow would lead to reduced heat output. Issues may arise from a variety of factors: creosote build up or other blockages in the chimney flue, insufficient ventilation, or negative air pressure within the home. These factors impact not only the heat of your fires, but also the safe usage of your fireplace system.

✓ Damper position. The damper is a movable plate inside the venting system which helps to regulate airflow. While your fireplace is in use, the damper should be fully open, otherwise the restricted airflow can reduce the heat and intensity of your fires.

✓ Poor or improper fuel. The type or quality of fuel used in the fireplace will have a direct impact on its heat output. Wood that’s damp or unseasoned will burn much less efficiently and generate less heat compared to well-seasoned firewood. Consider the species of wood you’re using as well – softwoods burn more readily, but with less heat production than the hardwood species.

✓ Insufficient insulation. If insulation around the fireplace or around the chimney is inadequate, this can contribute to heat loss. Heat generated by your fires may dissipate into surrounding walls or escape through gaps, diminishing warmth.

✓ Mismatched size. A fireplace that is too large or small for the room that houses it will impact heat distribution. An undersized fireplace may not produce warmth sufficient to the task.

What Can Be Done About Low Fireplace Heat

Just as there are a number of potential contributors to your low heat woes, there are lots of potential solutions.

  • Stay on top of professional maintenance. First, be sure to stay current on annual chimney inspections and cleanings. This will go a long way not only in assessing issues, but heading them off before they escalate. A chimney professional should have eyes on your chimney system top to bottom – annually – to help keep your flue clear and your system running optimally.
  • Adjust damper position. Verify that the damper is fully open every time you use it to allow ample airflow. This will lead to a thriving fire. Is your damper tricky to open? It may require an adjustment or repair.

  • Find ways to improve ventilation. Your chimney should be inspected for obstructions or blockages, such as debris, creosote buildup, or bird nests. Clearing these obstructions can dramatically enhance heat output – and safety! If excess debris is finding a way into your chimney, you should also consider installing a proper chimney cap to help protect your chimney system.
  • Use properly seasoned firewood. Firewood should have a moisture content of 15-20%. Why? Wood with moisture content in this range burns more efficiently, resulting in hotter, cleaner fires – as well as reducing the risk of creosote building up. Green or wet wood will result in smoldering fires with lower heat output into the home.
  • Improve insulation. Enhancing insulation around the chimney system and having any gaps or cracks in masonry repair will minimize heat loss. Another helpful addition? Installing glass doors on your fireplace can help with heat retention by warming the chimney – and prevent drafts when the fireplace isn’t in use.
  • Invest in a fireplace insert. If your existing fireplace simply struggles to provide sufficient heat, a fireplace insert may satisfy your craving for efficiency – and provide an opportunity to convert to a new fuel source or add new features. Fireplace inserts are self-contained units that are retrofitted into existing fireplaces, and they can significantly improve heat output. Some units come with fans to improve circulation, and many have adjustable controls for a high degree of control over your heating experience. Because inserts upgrade efficiency, they can also reduce energy consumption, meaning lowered energy bills and reduced environmental impact.

A fireplace that doesn’t deliver enough heat can diminish comfort in your living space. Fortunately, a little troubleshooting can yield a dramatically improved fireside experience.

Is my chimney making my house cold? ›

The stack effect

As this warm air rises, it needs to be replaced. So cold air is pulled in, usually from around doors and windows, creating the chilly draught that you can feel (and hear when it's windy). By cutting out draughts, you can keep your home nice and cosy.

How much heat from a fireplace goes up the chimney? ›

In fact, 80% to 90% of the heat produced by a wood-burning fireplace is lost through the chimney. Moreover, an open fireplace pulls in more air—both inside and outside—than is needed for burning, reducing the heating efficiency of your home even more.

Why is my fire not getting hot enough? ›

To create fires that produce more heat, open the damper as wide as possible when lighting a fire. A wide-open damper will increase the amount of air reaching the fire and improve combustion. As a result, the fire will burn hotter.

Why is my fire not giving out that much heat? ›

Over time, soot and other particles will build up in your chimney from repeated fireplace use. This will reduce suction and airflow to your fire – decreasing its heat output. By regularly getting your chimney swept, you can keep your fireplace clean and performing at its best.

Why can't I feel the heat from my fireplace? ›

Make sure to fully open the damper when starting the fire. When you have a great fire going, slightly close the damper to prevent excess heat from escaping. If the room still isn't warm enough, close the damper a little bit more. This will enhance your heating output.

Why is it so cold by my fireplace? ›

If insulation has dropped over time or was simply put in incorrectly, the gap between the wall and the fireplace will become a gathering place for cold air. Checking the status of insulation is not easy and may require pulling off siding or making a small hole so the insulated area can be seen.

How do I get my fireplace heat to circulate? ›

Place the box fan on low facing into the space where your fireplace is, blowing the cool air at the unit. This will cause convection reaction and the hot air will be forced away from the burning unit. If in a small room, the hot air will be moving out the door into larger spaces in no time.

How do I know if my chimney flue is blocked? ›

Some of the warning signs that could be due to a flue obstruction include:
  1. Your carbon monoxide (CO) detector is sounding an alarm.
  2. The fireplace fills with smoke.
  3. Difficulty lighting a fire.
  4. Fire burns out quickly.
  5. Black, tarry flakes inside the flue.
  6. Strange odor inside the firebox.

How do I know if my chimney is working properly? ›

If you smell a strange odor inside your home after lighting the fireplace, it highly indicates that your chimney is blocked and the fireplace may not be able to work. This is where you need chimney repair service and fireplace maintenance and inspection.

Am I losing heat through my chimney? ›

If you're unsure whether your damper is allowing heat to escape from your home, there's a simple test you can perform. With the damper closed, place a lit candle in your fireplace. If the flame dances around, rather than remaining steady, the warm air from your home is escaping past your chimney's damper.

Does a fire in the fireplace make the house colder? ›

The standard fireplace is among the most inefficient heating devices you can operate. In fact, it can be so inefficient that in some cases it actually makes your house colder. Inefficiency is not their only drawback.

How long does it take to warm a chimney? ›

Keeping the damper open while laying the fire will sometimes be enough to move some warm air into the flue but that can take up to a half-hour and there are quicker ways to preheat the flue: Make four or five newspaper “torches” by rolling a few pages up tightly.

How to make a fire burn hotter? ›

Make sure there is enough space between the logs to allow for sufficient oxygen flow and heat circulation. Place smaller pieces of wood on top of larger ones so that they burn quickly and thoroughly. Regularly add more kindling or tinder to help keep your flames burning longer and hotter.

How to increase heat output from a gas fireplace? ›

There are several ways to increase heat output from your gas fireplace. Some methods include using a fireplace blower to circulate the air, installing a heat exchanger, placing a fireback behind the fireplace to reflect heat, and converting a gas fireplace to a gas insert.
