Why You Need Residential Boiler Services in Hamilton

Understandably, many homeowners have a limited budget to spend on monthly necessities and venturing outside of that budget for unexpected repairs can be difficult, particularly if you have a family. That’s why a lot of residents throughout Hamilton and surrounding areas prefer to do DIY projects rather than calling in a gas technician to make to make necessary repairs and replacements throughout their homes.

When your boiler system fails for any reason, whether it’s low water pressure, sounds of kettling, water discharging from relief valve, venting issues, ignition system errors or circulator problems, you need the skills and experience of a highly trained boiler technician in Hamilton to rectify the situation. To avoid dealing with these issues in the middle of the heating season, you should be scheduling routine service checkups and inspections at least once a year to ensure that your boiler system is always working efficiently and in tiptop shape.

Residential Boiler Repair in Hamilton

There are multiple reasons for your boiler or combination boiler to malfunction or break down. You may think that it’s an unexpected occurrence, but it could be something that’s been brewing for a long time. Here are a few reasons your boiler system may require repairs or replacement:

  • Loss of water pressure
  • Blockages and scale buildup
  • Leaking water or discharging from relief
  • Missing insulation
  • Air pockets or airlocks
  • Thermostat or aquastat failure
  • Low water levels
  • Broken boiler circulators or bearings
  • High levels of carbon monoxide (CO) or soot
  • Red tagged by another contractor

No matter what issues your boiler is facing, you can rest assured that MDM Mechanical can diagnose the problem and make the necessary repairs in a timely manner with minimal disruptions to your schedule.

Residential Boiler Maintenance in Hamilton

As mentioned, if you live in Hamilton and the surrounding areas, routine boiler maintenance is pivotal to the overall health and longevity of your boiler or combi boiler system. Equivalent to getting regular annual checkups to maintain and look after your health, boiler maintenance can help keep your boiler system and components running for as long as possible and remedy any potential problems before they start or get worse.

Scheduling annual boiler system maintenance can help technicians spot potential problems before they become a bigger problem and recommend preventative solutions to help expand the lifespan of your boiler system and make necessary adjustments or repairs.

Different Types of Heat Exchangers

When it comes to servicing, maintaining, or replacing an older boiler with a new high efficiency boiler, there are a couple different types of heat exchangers available. While there are only a handful of different variations of heat exchangers used for boiler installation in Hamilton and surrounding areas, they are all welded stainless steel, aluminum or in cast iron sections that need to be built by hand.

Water Tube Heat Exchanger

Water tube heat exchangers are available from most manufacturers. Even though most high efficiency boiler manufacturers provide a 15-year heat  exchanger warranty, the water tube heat exchanger is a less expensive option compared to the other heat exchangers available. The combustion process happens around the welded tubes and the fluid (water or glycol) flows through the tubes by the force of a boiler circulator. Water tube heat exchanger boilers are a bit harder to service and typically fail sooner than other types of heat exchangers.

Fire Tube Heat Exchangers

Fire tube heat exchangers are robust, superior and the most reliable type of design. Most high efficiency boiler manufacturers have a boiler model with a fire tube heat exchanger. These models are generally more expensive but will outlast a water tube boiler. They are easier to service and come in larger BTU inputs than the water tube heat exchanger. The combustion process happens within the tubes and the fluid (water or glycol) flows around the tubes which transfers the heat. If you are planning on investing extra money into your boiler system replacement project, we highly recommend a condensing boiler with a fire tube heat exchanger.

Cast Iron Sectional Heat Exchanger

Cast iron sectional heat exchangers are typically used for low pressure steam boilers, atmospheric floor mounted boilers or fan assisted boilers. These types of boilers are extremely reliable and there are still boilers from the 1950’s that are still in use and maintained every year. However, these types of boilers are slowly becoming obsolete due to energy requirements and manufacturing processes. Cast iron sectional boilers are typically used in very specific houses and businesses and are not as efficient as a condensing boiler. Cast iron boilers are typically around the 75% AFUE range, have the most weight and take up more floor space than a wall mounted boiler. The exposed burners and valve train make them very easy to service.

Different Types of Boilers

At MDM Mechanical, we know boilers inside and out. If you are looking for high quality boiler installation, replacement, maintenance or repair in Hamilton, Stoney Creek, Burlington, or the surrounding areas, then you have come to the right place. We have extensive experience installing, repairing, or servicing the following different types of boilers.

  • Low - Mid Efficiency Boiler: These are the types of boilers that are commonly installed on the floor which are atmospheric vented, or fan assisted with a cast iron heat exchanger built in sections. These boilers have an AFUE (Annual Fuel Utilization Efficiency) of 70% to 82%.
  • High-Efficiency (condensing) Boilers: These are modern boiler systems that can be mounted on the wall or floor, depending on your space requirements, restrictions, or piping modifications. These boilers have an AFUE of 90% or higher with a modulation rate of 10:1.
  • Combi Boilers (combination boilers): High-Efficiency Combi Boilers are a central heating boiler and on demand instantaneous water heater all in one compact unit. They take up just as much space as a high efficiency boiler and are typically wall mounted but also come in floor mounted models as well.
