Sol-R-Beam Water Heater

Help! We are looking to repair a Sol-R-Beam water heater that was installed in 1985. It looks like a pretty straight forwartd repair but we do need to knoe the type of anti-freeze that was used and how much the system should be presurized. The owner of the system said that the indicator said 30 pounds for years.

Any help will be appreciated.

Re: Sol-R-Beam Water Heater

Richard, I usually use a non-toxic antifreeze that is available at most any plumbing supply companies. Any pressure between 10-30 lbs is acceptable. If you have an expansion tank in line, check it's rating. They are usually 15 or 30 lbs, so keep the system within it's rating and allow for pressure increase during hot days.

If you are familiar with the Sol-R-Beam can you help me with the sensor. The literature I have calls it a Tracker Eye Assembly, 2 Vactec VT235 type photocells. I can't find anything on the web about them. Also, where is the fill valve for the anti-freeze?

Re: Sol-R-Beam Water Heater

Richard, try searching for a photosensor. you may find an equivalent one online.
 As far as fill valves go, thet should be somewhere along the piping heading up to the collecors. There should be a circulator pump on the same line. The fill valves should have a hose thread adapter in most cases and most times is just a boiler drain. There should be two of them, one to fill and one to purge.
