HeatMaster / G200 Control Panel removal

« on: March 07, 2018, 03:00:15 PM »

I need to clean the LOGO display on the G200 Control Panel - somehow it has filled up with cobwebs - go figure!
Looks simple enough to remove the panel but when I tried loosening the 6 screws, the panel remained solidly attached.
Anyone done this before? I'm not anxious to try prying it open without understanding what I am doing.
I had thought there was a tutorial video out there somewhere but can't find it.

HeatMaster / Water heating problem

« on: October 29, 2017, 03:22:42 PM »

A G200 feeds my house and my garage - separate buildings.  Above the garage is a guest apartment.  There's a 40 gal. electric water heater in the garage (primarily for the apartment but also for my shop in the garage) that's hooked in to the G200 lines and has a heat exchanger sitting on top of it that is connected in to the cold feed and is as hot as hell!
Yet, the water coming out of the hot tap is cold.  If I run the hot tap for 5-10 minutes it MAY just reach tepid.

In the main house, everything works well.  The garage is exactly the same configuration.

I imagine the problem is insufficient, continual hot water useage out in the garage to allow the hot water to permeate throughout the water heater tank so while very hot water is coming in to the bottom of the heater tank it's just going cold by the time it gets to the top and feeds out the hot water tap.

Other than shortening the tank's cold feed to deliver hot water to the top of the tank does anyone have any neat ideas on how to fix this?
