There are three main types of gas-condensing boilers to choose from. Combination boilers heat water as you need it and eliminate the need for a storage tank. Heat-only boilers consist of a water tank or cylinder where hot water can be stored and used later. A system boiler is just like a heat-only boiler, but more components are built in.
Combination boilers are ideal for small homes with only one bathroom. If you have more than three people living in your home, a heat-only or system boiler will probably fit your needs better.
Humidifiers emit water vapour to increase air humidity in your home or office. They can help alleviate many cold weather conditions including dry skin, chapped lips, nose bleeds, and more. They can even help prevent snoring.
You can get warm or cool mist humidifiers. Warm mist humidifiers heat water then release the steam into the air. These are ideal for cold rooms, but the warmth can also encourage mould growth. These machines should be cleaned regularly. Cool mist humidifiers make more noise than warm ones. Water passes over a wick inside the machine and the resulting vapour is expelled.
