A boiler pressure-reducing valve set at 12 psi is generally considered acceptable for residential steam heating systems, especially in older homes such as Victorian buildings. In many cases, residential steam heating systems typically operate effectively within a pressure range of 1 to 15 psi, with 12 psi sitting comfortably within this range.

For these systems, maintaining a lower pressure helps prevent excess steam pressure that can lead to wear or damage to the system components. Additionally, lower pressure can improve energy efficiency and comfort by promoting a more consistent distribution of heat.

Understanding the specific requirements of the heating system can provide more context, but as a general rule, 12 psi would not be regarded as too low for the operation of steam boilers in residential settings.
