It's important to figure out what type of headache is causing your pain. If you know your headache type, you can treat it correctly. In one 2004 study, 80% of people who had a recent history of self-described or doctor-diagnosed sinus headache, but no signs of sinus infection, actually met the criteria for migraine.
Different types of boilers and boiler brands. The boiler market in the UK is dominated by one particular type of boiler: the condensing boiler. However, there are different types of condensing boiler, including combi-boilers, heat-only and system boilers. Popular brands producing combi-boilers include Baxi and Glow Worm (both Baxi heating boilers and Glow Worm boilers are British made).
About Boilers. Boilers and furnaces are often confused, but the terms are far from interchangeable. Both are systems that heat your home, but the similarities end there. Boilers heat water, providing either steam or hot water as a method of heat; furnaces heat the air. 1  Steam boilers distribute heat through pipes to steam radiators. 2  Hot water boilers distribute heat through baseboard radiators or radiant flooring systems, or they can send the heat to a coil that heats the air.
