Boiler servicing and threat of carbon monoxide poisoning

Boilers and furnaces that are not working properly or those that are poorly maintained can cause many problems, among the serious ones not venting flue gases out of the home properly. Not venting flue gases is caused, for instance by a plugged or collapsed chimney or crack or hole in a heat ex-changer. And carbon monoxide, being a poisonous gas and worst of it a odorless, colorless gas -- can kill people. In such a case where it is released from boilers and furnaces, it does kill most people while sleeping because most are at home at night.

Identifying problem areas when doing boiler repair in Harrow, boiler service in Harrow or boiler installation in Harrow is important to help avoid this problem. The heat ex-changer, for instance, which is the most important components of the furnace and creates warm air, may be the problem if it fails. It can start emitting carbon monoxide. To explain, the heat ex-changer becomes red hot and expands when the furnace turns on and heats. It expands and contracts thousands of times and it can crack. Severe rusting and holes in the heat ex-changer can also happen over time as a result of collecting of condensation exhaust from the furnace. These cracks and holes can release carbon monoxide.

This problem can be discovered by use of thermal imaging equipment during boiler repair Harrow, boiler service in Harrow and boiler installation in Harrow.

For purposes of protection, you should red flag a number of issues including rusting or water streaking on vent/chimney, a loose or missing furnace panel, sooting on internal or attic spaces, chimney connections and vents that are loose or disconnected, debris or soot that fall from chimney and fireplace or appliances, and loose masonry on chimney.  

There are a few signs or symptoms that can indicate exposure to carbon monoxide even when the gas does not cause death initially when there are low levels of the gas. It is important to notice because death can result after some period of time of exposure to moderate levels of the gas. High levels do kill within a few minutes.

It is important to have a technician check the boiler and furnace once a year or when you detect or suspect a problem. This is in addition to installing detectors and ensuring additional precautionary measures.

Otherwise, the heath symptoms of exposure are similar to many other common ailments including headaches, tiredness, and difficulty thinking clearly and feeling sick. Sometimes the symptoms are feeling as though you have food poisoning or that you are coming down with flu.
