ADD A RADIATOR Basic plumbing skills are needed to cut and join pipes. You also need to know about your heating system and how to drain it down Check for pipes and electric cables before drilling. Always make certain you have identified the pipe properly before cutting it. Know where to turn off the gas, water and electricity before you start work. If you use plastic pipes or fittings to join metal pipes, make sure you link the metal with an earth wire. Add a radiator to your central-heating system to provide extra heat. A radiator can be teed into any part of the central-heating flow-and-return pipes, but it is important that adding a radiator doesn't rob existing radiators of their share of the boiler output. Once you have established where to join the new pipes to the circuit, you can set about hanging the radiator on the wall. The best direction to work in is from the radiator to the heating circuit. Only when you reach the existing pipework do you need to drain down and cut the pipes. 2 - Where to connect Working out flow rates in pipes can be complicated but as a rule of thumb, a 15mm (1/2in) flow and return should serve no more than three radiators. If the radiators are more than 1000mm (40in) across or t pipe runs to the radiators are more than 4 metres (13ft then the number of radiator served must be reduced to two. This means that any 15mm (1/2in) heating pi serving more than this must not be used to connect an additional radiator. Instea you need to go back to the 22mm (3/4in) section of p or extend the 22mm (3/4in run so it takes in one of the excess radiators. If you follow this advice your radiators heat up efficiently (1). he ) s pe d, ipe ) will 3 - What size radiator do you need?

Radiator outputs are given in British Thermal Units and Kilowatts. Select a radiator to suit the heat you require. A 4m x 3m (13ft x 10ft) living room with two outside uninsulated cavity walls needs around 3kw to give 21 o C when it is minus 1 o C outside. The bedroom above it needs just 2.2kw because it doesn't need to be as hot and there is some gain from the heated room below. It is customary to add 10% to the figures above for exposed sites or very cold weather. If you select a radiator with a larger output, it can be controlled with a thermostatic radiator valve. A very rough rule of thumb is: the volume of the room in cubic feet multiplied by 5 = temperature requirement in BTUs.
