Boilers tend to wear down over time and can be dangerous if not properly inspected. Here are some tips to insure the safe and efficient operation of your condensing boiler.

12 steps to follow for your boiler checkup:        boiler room


Thoroughly inspect the fuel connection Check the joints to be sure they are tight, the pressure gauges and thermometers that they are in place and tight and that the valves are operative. Also check for any leaks in the fuel line. 


Fireside surfaces should be inspected twice a year. The fireside of the boiler includes all refractories, tubes, tube sheets and the furnace. Look for signs of blisters or pcok marks. This is an indication that there is corrosion due to condensation of flue gasses. 

Repair any substantial cracks using a wash coat to seal small cracks. If there are any loose bricks, repair or replace them. Boiler refractors expand and contract with changes in temperatures. For this reason some cracking will happen. 
Scale and deposits may appear on any waterside surface and are most commonly located at the heat exchange surfaces with the highest skin temperatures. Deposits usually found in a water system are calcium scale and iron scale. (Scale prevents heat transfer inside the boiler and can greatly affect efficiency.) Also common is sludge which can be found on any waterside surface. It is most often found in the mud drum or at the base of a boiler, in the tube bundle or on the end bells of a chiller. Conduct a boiler bottom blowdown to clear sludge and sediment, control high water, and control chemical treatment concentrations (monthly or as needed).

The burner is a very important component. It supplies the heat input by burning fossil fuel and is often adjustable for different fuel compositions, such as natural gas, light oil, diesel oil, LPG, or dual-fuel firing.  Visually check the boiler’s flames. If there are inconsistencies in the flame patterns or color, there may be an underlying issue. Make sure everything is in order before proceeding. Failure to maintain the fuel system could result in excessive fuel costs, loss of heat transfer or even a boiler explosion.


Steam boilers use pressure control devices to ensure that the boiler does not build up too
much pressure that would make the operating conditions of the boiler unsafe. Any controls used to monitor the water level of the boiler should be checked after reinstalling onto the boiler. Inspect all the operating controls and look out for any signs that show of overheating. Also inspect the fuel train (this controls and the flame appearance may require the services of a trained technician for proper adjustments to assure a correct fuel-to-air ratio) and the emergency shut off switch. Recalibrate all operating controls.


Check the boiler header valves, piping drains and vent valve. Inspect the vent to be sure it is not clogged and that the ventilation requirements for the boiler are met.


A condensate receiver is important because it captures the condensate emitted from the boiler and allows it to be reused.  This improves the efficiency of your equipment and it also extends the life of your boiler. Over time, these can become clogged with sediment cause your boiler to stop working.


Boilers and burners require a combustion analysis on a regular basis for proper operation. The combustion analyzer measures the air-to-fuel ratio of the burner and calculates the efficiency of the boiler. A combustion analysis should always be performed if you clean or replace the blower wheel, replace the blower motor, gas valve or gas pressure regulator.


Water treatment is needed before feedwater can be pumped into a boiler. A chemical treatment produces a reaction that consumes many of the scale-forming minerals. Water softeners are also used to remove calcium, iron and magnesium ions from the feedwater. Regulary test the boiler water and treat following the guidelines provided in the Installation and Operations Manual from the manufacturer.

This is the water being added to the boiler and/or the boiler feed unit. The system operates via closed loop so an excessive amount of fresh (untreated, oxygenated) water added to the boiler is detrimental to the components. This can be a sign of a leak in the system.


Keeping a record any problems and routine maintenance. It is crucial to catalogue inspection reports to allow you to determine if the current condition indicates equipment status is unchanged, improving or degrading.

Performing regular inspections of your  system equipment is an important part of a successful preventative maintenance program. Visual inspections provide an indication of the overall health of your system and validate the results of your water treatment program.

Why Your Furnace is Leaking Water

Posted by Ohio Heating

Feb 7, 2020 7:51:59 AM

If you have noticed that your furnace is leaking water, here is a list of the most common issues:

There is a clogged drain. Condensation from air conditioning coils contains bacteria that can form slime and clog the drain.   home furnace

There is a condensation leak.  High-efficiency furnaces create condensation as they utilize cool exhaust and then blows it away from your unit. When the tubing is damaged, broken or not functioning correctly, this could be the cause of your leak.

Standard efficiency furnaces should not have condensation. A leak is particularly unusual and could indicate an improperly sized flue pipe. If this is the problem, then hot exhaust might be condensing in the pipe as it cools down.

To see if your furnace is high- or low-efficiency you can examine the vent pipe.  If the pipe is PVC (white plastic), then it’s a high-efficiency unit. If the pipe is metal it is a standard-efficiency furnace. 

The secondary heat exchanger is not functioning properly. The leak might be caused by the secondary heat exchanger. This repair can be expensive, so most customers decide to replace the furnace as opposed to repairing the exchanger.

There is a humidifier leak.  A humidifier that isn't working properly can cause water issues. If you’ve stayed on top of your annual HVAC maintenance, then this probably isn’t the issue because your service technician most likely would have noticed the problem. If you haven't had a furnace check in a while, schedule an appointment immediately. This type of leak could cause serious damage to your unit.

Internal drain system clog. A plug in the internal drain system that operates in both the air conditioning unit and the furnace, could be directing water into the furnace. 

Don’t ignore leaking water issues. Leaks can cause significant damage to your equipment, walls and flooring, and can also lead to harmful mold growth. 

It's important to inspect your furnace, heat pump or boiler system annually to insure it is safe and performing at it's maximum level. Good preventive service keeps your equipment running at peak performance and reduces costly breakdowns. Schedule a furnace inspection now to insure your family's comfort and safety.

When you need a furnace repaired, call Ohio Heating & Air Conditioning. Our highly trained technicians are NATE certified and fully bonded. Regardless of the make or model of your HVAC equipment, or whether or not it was installed by us, we can repair it for you.

Wi-Fi thermostats also known as Wi-Fi Smart thermostats are very popular right now.  Typically they cost more than a regular thermostat and may homeowners are wondering if they are worth the added expense.

Your thermostat acts as the main point of access for your heating and cooling system. Many of these new models learn your schedule and that can save you money. A Wi-Fi Smart thermostat  can turn itself down when you're away, to avoid heating or cooling an empty house. Honeywell Wi-Fi thermostat

The more advanced models will even produce reports telling you how much energy you’re using and how you can utilize your system better, a feature well worth the slightly higher investment. The new temperature controls can pay for themselves in energy savings.

It allows you to determine when and at what temperature air is circulated. The remote access capabilities alone could be worth the extra money. While the features of the Wi-Fi devices are always changing and improving, even the most basic models allow you to: Adjust your home's temperature anytime, anywhere from a mobile device. 

(Keep in mind that most utility companies offer rebates on the newer thermostats, to help you offset the cost.)

There are plenty of devices to choose from: Honeywell, Nest, & Sensi are a few of the top brands.

Should You Buy a Air Filter with an 8 Merv Rating or One with an 11?

Posted by Ohio Heating

Jan 18, 2020 9:54:39 AM

Having clean air in your home is important for the health of your family. The most efficient way to filter household air is through your home's forced-air heating or central air-conditioning system. Do you know how to choose the best filter for your home?air cleaner 22-108529-edited

The filters are built into the return-air duct work, trapping particles as air passes through. These systems are passive; as long as the fan is running, they are constantly filtering all the air in your home.

Whole-house filters come in four main types. Understanding the ratings of air filters can help you decide which is best for your home and your family.

Filters are rated on a scale using MERV. This stands for Minimum Efficiency Reporting Value. lt rates the filter on how well it can catch particles in your home’s air.

The higher the Merv rating, the more efficient the air filter is at catching pollutants inside your home. Mold, pollen, dust mites, bacteria, tobacco smoke and pet dander are some of the pollutants common in homes. 

According to the American Society of Heating and Air-Conditioning Engineers (ASHAE), there are 4 general tiers or categories of MERV ratings:
• MERV 1–4 (decent): A filter in this MERV range is a disposable fiberglass filter. These can pick up particles that are 10 microns or larger, which include pollen and regular standing dust.
• MERV 5–8 (good): These are better at catching smaller particles (3–10 microns) like mold spores, hair spray, dust mites and animal dander.
• MERV 9–12 (better): These are considered the best option for residential use. These filters can remove pollutants as small as 1–3 microns, which includes particles like humidifier dust, auto emissions and legionella.
• MERV 13–16 (best): These filters are usually only found in hospitals because they can capture particles as small as 1–0.03 microns in size. Particles this small include bacteria, tobacco smoke and even the contaminants in sneezes.

(Air particles are measured in microns (one-millionth of a meter). The smaller the particle size in microns, the bigger the MERV rating you’ll need to trap it.)

There are three things to consider when  choosing an air filter. 

1. Do you have a limited budget? The higher the MERV rating the more expensive the filter. 
2. How many pets are in your home? If you have pets iin your home, their dander is picked up and distributed by your HVAC system throughout your home. A filter with a MERV 8 should eliminate most animal dander, but if you have more than one pet, you may need a MERV 11 to completely eliminate those harmful particles.
3. Does anyone have health health issues? If someone has asthma or allergies a MERV 11 filter would be the best choice. This filter can pick up smaller particles than a MERV 8 filter.

4 Most Common Reasons Your Boiler Breaks

Posted by Ohio Heating

Dec 31, 2019 8:00:00 AM

No hot water or heat? There are many reasons why your boiler is not producing hot water or heat, from broken diaphragms and airlocks to motorised valve failures or low water levels. A qualified boiler technician should be called to identify the issues and replace any failed parts.Boiler repair 2019 1

Four Common Issues

1. The condensate pipe is frozen.
Your boiler's condensate pipe transports acidic water that is produced by waste gas from the boiler to an outside drain. This pipe can freeze. Your boiler may then display a fault code which will alert you to a problem with the condensate pipe.

2. The pilot light is out.
The gas supply may be stopped by a broken thermocouple. T
his could result in the pilot light going out. Also a build-up of residue on the pilot light could also cause it to fail.

3. There is a loss of pressure.
Your system could have a pressure issue if your pressure gauge reads below 1. This can be caused by a water leak, or a faulty pressure relief valve. 

4. The boiler is kettling.
When your boiler is making a deep rumbling sound, as though it were a giant tea kettle about to boil over, you have a pretty serious problem with your system. It is most often because of lime scale or sludge build up on the system’s heat exchanger. This can restrict water flow. The water then boils, creating the kettle sounds.

Boilers can break down at any time, but usually fail in the winter months following a long period of inaction. The sudden pressure on the system’s components often cause a breakdown – at a time of year when a household needs heating and hot water most.
