Welcome to the gang Mack Truck, enjoy here and out in the playground.
The only thing I could add to all the replies in your question in 'Techies Corner' would be, you would have to have hot water at all times you want to use the SEH. I only turn my water heater on in time for a shower. I have a gas heater in my TeePee and works well at very low temps.

G'day Mack Truck and welcome to the forum. Don't forget to try the two ongoing games here - 'Who is This' in the 'I Digress' section and 'Pick this Place' in the 'General' Section - a great source to find new places to visit. Can't help on the heater as we don't use one.
And its welcome from us two 2 M T we have a diesel heater works a treat
