Radiators & Heaters
Radiators have been around for a long time as hot water is a very common form of heating for homes. A radiator is essentially a metal structure that is made up of hollow areas that fill up with hot water, this in turn heats up the metal which warms up the room. Eventually the water cools, and the cold water moves down to the bottom of the radiator, before leaving via a pipe. The hot water stays at the top, which is why radiators are typically hotter at the top than at the bottom. Hot water is conveyed to the radiators using one of three methods: pressure pump, gravity, and convection. They are a necessity for 21st century modern life, and at Howarth we have a wide range of radiators and electric heaters to help you spread the warmth.
Types of Radiators
Before you decide which radiator would be the best fit for you, there are a few things you need to consider before making any decisions, for example: the type of windows you have (single our double glazed), whether your house is sheltered or exposed, and whether the size of the radiators could fit inside your home.
Steel is the most popular material of radiator, as it is an excellent heat conductor. They also heat up quickly, and they retain heat for a long time even after the central heating has switched off. Column radiators are traditionally styled radiators and are made from hollow tubes of mild steel or cast iron, and have been designed to maximise the surface area, which allows them to heat a room up rapidly.
Panel radiators are one of the original forms of radiator and can distribute both convection and radiant heat. They are fast, silent, and responsive.
Compact radiators are like panel radiators, except that they have a more modern look to them and can blend into any room in the house to provide guaranteed heating.
Towel rails have become widely popular over the last few years due to its trendy, modern appearance in most home and hotel bathrooms. Although towel radiators may not give off an extreme amount of heat in comparison to our compact radiators, they are great for keeping your towels fresh and dry and are nice to look at.
