Battery Backup Steam Boiler
Been reading and following this page since I bought my new house a year ago. Never had steam heat and found great resources here. Been reading Lost art of steam and it's companion to learn more. Have been using what I read to help myself understand and gear my questions to the service techs who arrive. Who also was linked with this site.
My question, which my tech said he never had experienced before is.
We had a brown out the other day. I was home to experience it for the first time. Lived in this area 15 years first time I been through one. My battery backup on my computer and to alarmed throughout that power inadequate. My GFCi that had a trip alarms were all alarming due to lack of power. All lights dim.
The issue was my boiler automatic water fill was running and adding water to boiler. To a point that the boiler was full. I turned off the line to the boiler and the relay and such kept making the noise as it was calling for water. But at least the boiler was not receiving any more water. Instantly called to schedule a tech for that day. Drained 5 gallons out of boiler which took me back into upper level of sight glass.
Before tech arrives. Power goes full out for an hour and back on full power. Reset the gfci's, checked the battery backups all good. Thermostat called for heat, boiler fired up ran fine. Did not call for more water.
Tech arrives we discuss issue. His belief if that with the Brown out. The eye in the automatic feed, wasn't receiving enough power to read the boiler had water, which caused it to keep calling for water. When power restored it had enough power to read the water level. I asked if I didn't turn off water is there an over flow or drain. He mentioned , No, my system could of filled the radiators til it found a path of resistance to leak from.
My system is a two-pipe system.
So I asked what I can do. He didn't really direct. So. After he left. I thought of some type of battery backup for the boiler would probably be a good idea.
Has anyone else experienced similar. Any remedy, besides going full house backup generator.
Sorry about long winded post. Will continue reading posts.
