Yes looking forward to summer in more than one way. My parents basement is quite warm, as it is, a finished living quarters as such. Although, right at this moment just with the cat.
The frosting problem was just purely not enough air flow through the evaporator. I had tried to exhaust it into a 4" duct, but it proved insufficient. There is room for slightly improving increase airflow.
I want to again run a test for calculating the COP. Also I've a programmable thermostat for the HWT instead of the bi-metal original.
Get the grinder out and fire up the torch these things work great!! Well worth the effort and time. Let the other guys worry about the sports on Saturday!!
