Bought a radiator to replace a towel rail. However, the towel rail 'fixings' come up vertically from the floor into the bottom of the unit. The radiator 'fixings' go into the sides. The plumber doesn't want to drain the system so I am looking for a radiator that has fixings coming out vertically at the bottom (with no luck so far) Is there such a thing or am I going to have to get a new towel rail instead ? I wanted a radiator as I need high output btu's due to my cold kitchen.
