Combo Unit
Our new combo units have two modes. The first mode is gas only where it will operate identical to our standard 5HP GHAB where it will run with high gas to get up to temperature, and then switch to low gas to keep the switch clear. When it is set to gas/electric mode it will run with gas to get up to temperature, and then switch to electric to keep the switch clear, and if it runs out of gas it will switch over to just electric. This will greatly reduce the amount of gas used.
