Why Is My Boiler Leaking?

Why Is My Boiler Leaking?



Your boiler can serve you reliably and effectively for many years. Boilers have an average lifespan of 20 years. However, like every other home system, they may experience problems such as leakages. Water leaking boilers require the attention of an experienced technician since they could lead to damages. We recommend regular boiler maintenance in the Greater Toronto Area by our technicians at A-Plus Quality Heating and Cooling to prevent such issues. Below are some of the common causes of leaks in boilers and what to do.

Possible Causes of Boiler Leaks

There are many reasons for leaking boilers, but we will discuss a few of the most common causes. They include the following:

Corrosion

When dirt and debris buildup inside your boiler, it encourages corrosion of pipes and radiators. Over time corrosion weakens your tanks and pipework, which eventually leads to water leaks. If rust and corrosion have not spread further than a valve or a single pipe, then replacing the part can resolve the issue. However, if it has spread across the boiler, you will need to replace the whole system.


Pressure

High pressure is the most common cause of leaks in boilers. Boilers come with an outlet pipe that lets out excess pressure and prevents the system from imploding. The recommended pressure is between 1 and 2. If you notice the pressure gauge reads more than that, you need to reduce it.


Temperature

All boilers come with a temperature control valve (TCV) that monitors the water temperatures. The TCV regulates the water temperatures from getting too high. If you notice leaks from the TCV, it’s a sign that the temperatures are too high.


Pump seals

Due to contraction and expansion over time, your boiler pump can develop cracks that cause water leakages. The pump requires either resealing or replacement.


Loose Joints

Your boiler expands and contracts as temperature changes from cold to hot. This change can affect the joints and cause leaks. Through boiler maintenance in the Greater Toronto Area, the joints such as all pipes and tubes connected to the body can get tightened.


Wear and Tear

Like everything else, boilers do not last forever. If your boiler is old, it could experience leakages, and you need to replace it. It also consumes a lot of energy that leads to high monthly bills. A new system will not only save you money but will also offer you efficient heating.


What to Do if a Boiler is Leaking

The cause of leaking boilers can either be simple or complex. Nevertheless, they require immediate inspections from a certified technician from A-Plus Quality HVAC services in the Greater Toronto Area. While you should not attempt to perform repairs on your own, there are a few steps you can take to protect your home.

•  Turn off your homes water supply 

•  Switch off the boiler

•  Wipe any leaked water

•  Finally, contact a qualified technician for boiler repair in the Greater Toronto Area from A-Plus Quality Heating and Cooling.

FAQ

  • Why should I maintain my Furnace or AC?

    An annual maintenance will extend the lifetime of your heating and cooling unit. The technician will diagnose and repair any problem with the unit before it fails, so you won't need to worry about any problems when the weather gets very hot in the summer or extremely cold in the winter.

  • What are mini-split advantages?

    Just as the name implies, a “mini-split” system is a “split system” however available in smaller capacities, for single room to whole house conditioning. Mini-split systems may range from as small as 9,000 BTUh per hour, comparable to say, a small window AC unit, for individual room use, up to 4 and 5 ton capacities for “Room By Room” (also known as “Zoning”) and whole house conditioning. With near universal design, mini-splits are “heat pumps” which provide both heating and cooling for a home. Here are key advantages when compared to traditional split systems:

    Efficiency- Mini-splits are highly engineered systems which offer attractive operating efficiencies, in many instances, eligible for utility company rebates.
    Heat Pump- Most mini-split systems are heat pumps, providing year-round comfort.
    Solar friendly- Due to very low power requirements, mini-splits are an ideal complement to “Net Zero Energy” homes, or any home using renewable power.
    Carbon footprint- Mini-splits are 100% electric, with zero operating emissions of any type.
    Zoning- Most mini-split manufacturers offer systems capable of room-by-room “zoning”, to account for peak demands of a room based upon construction type, exposure orientation and usage.
    Variable capacity- Mini-splits are typically DC inverter driven. That is, a variable speed compressor which modulates in proportion to instantaneous demand. Most conventional split systems, by comparison, operate with an ON-OFF strategy. (Would you use an ON-OFF switch as the accelerator in your vehicle?)
    Location, Location, Location!- Mini-split outdoor units are compact; they can be located far away from noise-sensitive areas, such as bedrooms and home offices. Mini-split indoor units have the ability to be installed where conventional systems cannot.
    They’re perfect for additions and remodels where access to current HVAC system is difficult to access.
    Modern mini-split systems are remarkably quiet; in fact, many times their operation is unnoticed by the end user.

  • What is a mini-split?

    By definition, and simply put, a “Split System” is a heating and air conditioning system which has two main components, the indoor unit and outdoor unit. In short, the indoor unit absorbs heat energy in the cooling mode, and the outdoor unit rejects the very heat absorbed by the indoor unit. And the cycle is repeated until the set temperature is met. Although the indoor and outdoor units are located in physically different, hence “split” locations, they are connected and operate as, one system; continuously circulating refrigerant liquid and vapor by means of interconnecting, dehydrated copper refrigerant lines, commonly referred to as a “Line Set”.

  • What is a heat pump?

    Heat pumps use electricity to move heat from a cool space to a warm space, making the cool space cooler and the warm space warmer. During the heating season, heat pumps move heat from the cool outdoors into your warm house and during the cooling season, heat pumps move heat from your cool house into the warm outdoors. Because they move heat rather than generate heat, heat pumps can provide equivalent space conditioning at as little as one quarter of the cost of operating conventional heating or cooling appliances.

  • Why is there ice building up on the copper pipes?

    There can be many reasons why the refrigerant pipes are freezing up but the most common issue is low refrigerant levels. If your AC unit has ice buildup turn off the unit for at least 4 hours and call us at 416-410-0337
