Here at Epic Boilers, we believe that a warm home should also be a safe home. We often talk about the efficiency and reliability of our boilers, but there's another crucial aspect of home safety that every homeowner needs to be aware of: Carbon Monoxide (CO). It's an invisible, odourless, and tasteless gas, earning it the terrifying moniker of "the silent killer."
What is Carbon Monoxide and Why is it So Dangerous?
Carbon monoxide is produced when fuels such as gas, oil, coal, and wood don't burn completely. In your home, this can happen if a boiler, gas fire, or even a wood-burning stove is faulty, poorly maintained, or improperly installed. The danger lies in its insidious nature. You can't see it, smell it, or taste it, meaning you could be breathing in dangerous levels without even realizing it.
When inhaled, CO prevents your blood from carrying oxygen effectively, starving your vital organs of the oxygen they need to function. Symptoms of CO poisoning can be easily mistaken for other common illnesses like the flu or a hangover, including headaches, dizziness, nausea, tiredness, and confusion. Prolonged exposure can lead to collapse, coma, and even death.
The Lifesaving Power of a £15 Gadget
Given the invisible threat, how can you protect yourself and your loved ones? The answer is simple, affordable, and incredibly effective: a Carbon Monoxide detector. For around £15, you can purchase a device that constantly monitors the air in your home for the presence of CO, sounding a loud alarm if dangerous levels are detected.

Installation Tips and Ideal Locations
Installing a CO detector is straightforward, but correct placement is key to its effectiveness. Here are some tips:
Near Fuel-Burning Appliances: Install a detector near your boiler, gas fire, or any other fuel-burning appliance. This allows it to detect leaks at their source.
Sleeping Areas: Place detectors in or near bedrooms. Many CO poisonings occur while people are asleep, making early detection in these areas critical.
Eye Level: Mount the detector at eye level, or on a wall roughly 1-3 meters away from a fuel-burning appliance. CO mixes evenly with air, so unlike smoke, it doesn't necessarily rise.
Avoid Obstructions: Ensure the detector isn't blocked by furniture, curtains, or anything that could prevent air from reaching its sensor.
Avoid High Humidity Areas: Don't install in bathrooms or very damp areas, as moisture can affect the sensor.
Read the Manufacturer's Instructions: Always follow the specific installation guidelines provided with your detector.
Ideally, you should have a CO detector on every level of your home, and especially in rooms where fuel-burning appliances are located and in sleeping areas.

The Gas Safe Regulations Importance
While a CO detector is your first line of defence, preventing CO leaks in the first place is paramount. This is where the expertise of Epic Boilers and the importance of Gas Safe regulations come into play.
Faulty or unserviced boilers are a primary cause of CO leaks. That's why it's absolutely crucial to have your boiler serviced annually by a Gas Safe registered engineer. Gas Safe registered engineers have the necessary training and qualifications to work safely and legally with gas appliances. They can identify potential issues with your boiler's combustion, flue, or ventilation system that could lead to CO production.
At Epic Boilers, all our engineers are Gas Safe registered. We not only install high-quality, efficient boilers but also provide comprehensive servicing to ensure they operate safely year after year. When you choose Epic Boilers, you're not just getting warmth; you're investing in peace of mind, knowing your heating system is in expert, safe hands.

In summary, while the dangers of Carbon Monoxide are real and severe, protecting your home is straightforward and affordable. Invest in a £15 CO detector, install it correctly, and ensure your boiler is serviced annually by a Gas Safe registered engineer. Your life, and the lives of your loved ones, are priceless – let's keep them safe this winter and all year round.
