Heat mat isn't hot enough.

[Zincubus]

Thanks for the fast reply!

The ground temp is reading at about 24C. The thermostat probe is right on the bottom of the RUB (no substrate or towels in atm, just doing a test run before S-Day). This is on the hot side, right above the heat mat.

What are you using to test the temperature incidentally ?!
Most of the heat mats I've ever tested easily reached 30C+.

Presumably , the heat mat is on a unit , then the rub placed over the heat mat ?

How much space between the mat and the rub ?!?

Just wondering if the some of the heat is escaping sideways .

I've seen similar reports and they got round it by putting tin foil under the mat to reflect some of the heat up towards the tub .

I've read about one bloke who put a magazine under the heat mat just to reduce the gap between the mat rub ....
