Hi there!
We just had our old pool heater replaced with a RayPak 156 unit. On heating, the outer shell (the metal case) gets hot to touch along both sides of the heater - is this normal for a unit like this? The literature only suggests that 'paint blistering' because of the heat is an issue, which seems obvious. But the sales materials talk about 'cool to touch' as it works, so I'm confused what is 'normal'.
Any help would be greatly greatly appreciated.
