HTP VersaHydro Solar whining

jklingeljklingel Posts: 1Member
I have a 4-yr-old HTP VersaHydro Solar propane mod-con boiler, and it has a loud whine in it periodically. The whine started a year or so after installation. A factory tech, myself, and a boiler pro all recently felt the whine indicated a bad blower fan bearing, so I replaced the blower fan. That was 2 weeks ago. All was fine for 3 days, but the whine started again. It only whines when the blower fan is in the range of 27-29% of the max speed. Also, the boiler will sometimes run quietly in that speed range. A week ago I called a factory tech and he said it sounds like another bad blower fan bearing, or a propane pressure problem. A pro is coming Tuesday to measure the pressure in the manifold as a starting point. Has anyone else had a similar whining problem? No one in my town works on these boilers, so any information/experience I can pass along to the pro will be appreciated, even if the same problem has happened to you on a different brand. Thanks in advance, and I hope I made myself clear. Puzzled in Fairbanks.

    Someone needs to do a combustion analysis and tune the boiler properly. Simply guessing and adjusting gas pressure will not fix this.

    Contact HTP . We had a unit that we designed for in Maine that had a few issues . First issue was wet gas (propane) , propane guy addressed that . No fan issues on that one . Issue 2 was the 0-10v control on the on board circ was operating below 4 volts at times in a really tight house which created an issue with noise , we addressed that by changing the programmed Delta from 20* to 10* , sped the circ flow up and issue disappeared .

    HTP has a device they can send you to be hooked up and monitored remotely by engineering at HTP to assist in identifying issues
