New builders also don’t take into account the weight of water in water cooled machines which is why it’s better to use an air cooled one on a smaller hobby machine. Plus water is another thing I would want to keep away from wood. I got some lubricant on my waste board the one time and it had to be replaced because it swelled up over night.

I take it you use an air cooled radiator in your lounge then so it does not ruin the carpet

The pedant in me wants to point out that yes, my radiators are air-cooled. They're also water-heated!
