I have a 2001 Beaver Patriot with a HydroHot HHE-500-03M. I just replaced the low fuel float and have a new board available if it is needed. When running the heat I am getting very sluggish power to the heater fans. It seems that it runs for a few minutes and then sounds like it is running out of steam. It will then rev up again and go back down until it finally turns off. The hot water is also not lasting long at all.
In February 2016 I replaced the burner and the mixing valve on the Hydrohot. If anyone has any suggestions it would be greatly appreciated.
Thanks,
