In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
Worked on the first one of these I've seen. No manual and whomever installed it placed screws for rear panel to the wall making it tought o get at. At least I could get to the electrical panel and one of the press. switches if they need serviced. Looks more like a central vacuum power unit than a boiler- tall and cylindrical. It makes a popping sound somewhat like a Pulse furnace, hence the name, I assume.
The problem was simple enough, gurgling sounds suggested to me the burner chamber was full of condensate. Found cond. drain blocked, cleaned out cond. port of boiler, fired up and all OK, except for a sticking zone valve.
Now, has anyone had experience with these units? Someone wrote 3-5-84 on a side plate, I assume this was install date and a co-worker said the home is around 20 yrs. old. Are they still made and are parts available? Fuel is LPG. Any helpful suggestions for general preventive service on this unit? Meanwhile, I will contact a Hydrotherm dealer to see if a book is available to help me figure the inner workings of this thing.
I have several concerns with this particular boiler. One, the combustion air intake is open to the atmospehre with no turn down or screen & exhaust leans from boiler, causing condensate to drip onto walkway. There may be small leak(s), but without completely removing the jacketing, could not tell for certain. Also, I would love to repipe this baby with P/S, pumping away; add a proper air eliminator, outdoor reset & relocate it so a guy can work on all components, etc. Thanks- Greg
