Is A Leaking Boiler Dangerous?

A gas leak or carbon monoxide leak can be extremely hazardous to building occupants. If you believe you are dealing with this type of leak, you will need to obtain help immediately and evacuate the building. However, there are some steps that should be taken before leaving, which are explained below.

Water leaks are usually less dangerous but can cause significant damage to a property in a surprisingly short period of time. However, they may be dangerous when water from a leak comes in contact with electrical appliances or electrical outlets. Contact a professional immediately if you are dealing with a large amount of water leakage.

What Does The Viessmann Vitodens 200 Have To Offer?

The Viessmann Vitodens 200 series pushes the boundaries of terms of what domestic gas boilers are capable of. With incredible energy efficiency, advanced controls, and smart home integrations, it is one of the most advanced boilers on the market.

The Viessmann Vitodens 200 is available as a combi boiler or system boiler, which gives consumers flexibility when planning their property’s heating system. Here are a few standout features of this boiler range.

Improved performance
The most significant change in the Viessmann 200 range is the very high modulation ratios of each unit. This specification refers to a boiler’s ability to reduce its maximum power output to its minimum output.

For example, a boiler that has a maximum output of 30kW and a minimum output of 7.7kW has a modulation ratio of less than 4:1 (30/7.7 = 3.89). The Vitodens 200 boilers have ratio of between 1:10 and 1:19, which is much higher than most other boilers on the market.

So, what does having a large modulation ration do for you? Well, there are two main advantages. The first advantage is that the boiler can modulate down to extremely low output very quickly, which means there are fewer on/off cycles. This improves boiler longevity and fuel efficiency. It will also make the boiler run cooler.

The other benefit is for combi boilers specifically. A combi boiler with a good modulation ratio will have a stable flow temperature at a low flow rate. This means you can turn a tap on low and still enjoy an adequate amount of hot water.

The Viessmann 200 is the only domestic boiler to feature a ‘Lambda combustion control system’. This system will measure the combustion quality and make adjustments to the fuel/air mixture. It can account for any variation in the quality of incoming gas, automatically improving the efficiency of combustion.

The improved mass flow sensor is a wonderful addition to the Vitodens 200 range and it also features the revolutionary Inox radial heat exchanger for which Viessmann is known.

Sleek colour touch screen
As mentioned earlier, Viessmann are at the cutting edge when it comes to technology. This is immediately apparent when you first use the 5” touchscreen.

This screen displays the current temperature, boiler status, gas input, and electrical input. It makes it simple to change settings for water temperature, weather compensation, heating temperatures, and heating zones.

The ‘energy cockpit’ section lets you monitor energy usage, so you know how well your boiler is performing over time. This is a useful addition for anyone interested in tweaking their home heating system to reduce energy bills and their carbon footprint.

It is an intuitive system that most people can pickup within a couple of minutes. It also has connectivity for external controls and room sensors which connect to the boiler over radio remote control.

Wifi Capabilities
All 200 range models can be WiFi enabled and configured to work with smart home devices. This means you can use a mobile app to control your boiler. The mobile app even allows for home automations, where you can have your boiler automatically increase its temperature at certain times or sense when you are on your way home and turn on prematurely. These automation tools can help you save money on energy bills and improve the comfort levels in your home.

Several Models To Choose From
There are several models available with different output heating levels, which makes it easy to find a system suitable for the size of your property. It also makes this series useful for properties with lower heat demands or a multi-zoned heating system.

The models includes devices with a 19kW, 26kW, 30kW, and 35kW output. The modulation ratios for these boilers range start at 1:10 for the lower power systems and increase to 1:19 for the largest system.

Any Downsides?
There aren’t many downsides associated with the Viessmann 200 boiler range. The only significant downside is that the boiler is larger than some other products on the market. This can make it difficult to fit this boiler into apartments and homes with very little room available.

The technological sophistication of the boiler also means that some electrical components are expensive to replace. So, if a major problem happens and the printed circuit board fails, it may cost a couple of hundred pounds to replace. Having said that, Viessmann products are so reliable that failures are extremely rare.

What To Do When A Boiler Leak Occurs

Gas Leaks
A gas leak is a serious and potentially life threatening problem which needs to be acted upon immediately. If you smell gas in your home:

1. Evacuate children, the elderly, and pets from the building
Reduce the number building occupants immediately by evacuating any person or animal who doesn’t need to be there.
2. Call for help (walk outside if using a mobile phone)
Call the National Gas Emergency Helpline on 0800 111 999 to report a gas leak. They will immediately call for a Gas Safe Engineer to visit your home and notify authorities. Alternately, you can call the emergency hotline of a local business with Gas Safe Engineers, like Quantum as Engineering (phone 0203 633 6322). Make this call on a landline or walk outside to use your mobile phone to avoid a spark being created.
3. Avoid any actions which may ignite gas
As you walk around your home, avoid any actions like using light switches, turning computers on, or lighting a match.
4. Open all doors and windows
Opening up your house will help the gas escape before it can build up to dangerous levels.
5. Switch off your gas supply
There will be a valve on the incoming gas line that can be turned to stop gas flow. Locate this valve and turn it off.
6. Evacuate yourself
It’s safer to wait outside until help arrives.
7. Seek out medical attention
If you are feeling unwell, see a doctor.

A Gas Safe Engineer will be required to address the problem cause your gas leak. Give Quantum Gas engineering a call to get the repair started.

Carbon monoxide leaks
If your carbon monoxide alarm goes off or you notice the symptoms of carbon monoxide poisoning (headache, sickness, dizziness, fatigue, stomach pain, difficulty breathing and confusion), follow these steps:

1. Evacuate children, the elderly, and pets from the building
Reduce the number of people and animals in the building immediately.
2. Open all doors and windows
Opening up your house will help the carbon monoxide escape.
3. Switch off your gas appliance
Turn off your boiler or the gas supply.
4. Evacuate yourself
Leave the property and stay outside until help arrives.
5. Call for help (walk outside if using a mobile phone)
Call the National Gas Emergency Helpline on 0800 111 999 to report a carbon monoxide leak. You can also call Quantum as Engineering on 0203 633 6322
6. Seek out medical attention
If you are feeling unwell or experiencing the symptoms of carbon monoxide poisoning, see a doctor.

Water Leaks
If you notice that your boiler has begun to leak water, here’s what to do:

1. Make sure the water isn’t in contact with electrical appliances or outlets
If you have a large amount of water on the ground, perform a visual inspection to determine if it is in contact with anything electrical. If you are unsure, turns the electrical mains off while you get a closer look.
2. Turn off electricity to the boiler
If you have a modern boiler, it will use electricity. You should turn this off as an additional safety measure. Look in the main box for the switch labeled “Boiler” or “Heating system” and turn it off.
3. Place a bucket, bowl, or towel beneath the leak
If you have a small leak, this should be sufficient to collect water before it damages your property
4. Identify where the leak is coming from
See if you can determine where the leak is coming from. If it is obviously coming from the temperature gauge or pressure relief valve, then you already know the cause.
5. Perform the repairs
If you are a handyman, you may be able to tackle minor issues like a corroded valve or pipe. If you don’t have the time or the necessary skills, give Quantum Gas Engineering a call on 0203 633 6322.
