[QUOTE="phil d, post: 452716, member: 27126"] THIS IS NOT ! A) Going to work! B) Be safe! C) Comply with the relevant safety regs! D) End at all well! A heating circuit is just that, a circuit, it needs a flow and a return, plus temperature stats, overheat stats and pressure relief devices. You cannot take cold water from a main, send it into a load of pipework, heat it up and expect it to heat a room, then connect the other end to a tap. Think about this, when you turn on a hot tap, you don't get hot water instantly, there is always an amount of cold water comes first, dependent on how far the tap is from the heat source, this is known as the "dead leg". Connecting the way you propose you'll have a massive "dead leg", then you'll probably get about a gallon of luke warm water before it goes cold again. The room will not be heated either, the only thing you may do successfully is create a breeding ground for the Legionella bacteria, and let me tell you, if you are responsible for an outbreak of Legionnaires disease then may god help you because it's jail time! As everyone else has said, you are woefully out of your depth here, for the sake of your family, get a professional in. [/QUOTE]
