    Radiator size

    Hi. Currently have 3 small double radiators (500x600) in our open plan living room/kitchen diner. Would like to change them for single panel designer radiators. Do I just need to double the size (1000x600) to achieve the same heat output? Thanks in advance for your help.

    Expansion vessel size unvented hot water

    I think I looked into it a few years ago. That a modern 200litre unvented cylinder would need a higher litre expansion vessel then one that was saying 10-15 years old. As they are made of thinner steele now?

    Old pipework size in bathroom

    Hi I've had to cut hot and cold feed to re route for bathroom feeds. The 22mm Copper pipe hot feed is slightly smaller then my 22mm Copper. Solder fittings just slip over it and are really loose so I gather this is old imperial pipe, so I shall use a 3/4 to 22mm coupler. However on the...
