Hi there,
\n My friend has a Burnham V904 boiler, and the burner was converted from burning oil to gas last fall, and since it was put into summer water-heating-only mode, the boiler only kicks on for a few minutes – not enough time to make hot water. So now the aquastat on the hot water tank is set at 140 (like it normally is), and the aquastat on the boiler at 212 (supposedly it should be set to 190), so that it will stay on long enough to make hot water. So now there is steam running through the heating pipes near the boiler and it seems very inefficient.
\n A guy looked at it and advised to replace the aquastat, which did nothing. I suspected that maybe the water pump wasn’t working at full strength, and thus the boiler was clicking off because the heated water was not being moved out of the boiler quick enough. However, my friend says that this is unlikely, since the boiler apparently behaved the same way when the backup pump was used. Any ideas? Is this normal? It’s only hot in the bathroom nearest the boiler and in the unit above it, do they just have to endure?<\/p>\n
Thanks in advance!<\/p>\n","protected":false},"excerpt":{"rendered":"
