Correct temperature setting for hot water heat/furnace

Sep 23, 2012 · Most boilers have a min/max setting - yours may be set too close together. Also, you may need to consider an outdoor reset control that will adjust the boiler's temp based on the outside temp (thus load). It's highly likely that for most of the winter, you could heat the house with lower temp water.

What is the safe pressure for a hot-water-heating system?

Most residential hot water heating systems run at 5-psi more than the pressure required to raise the water from the fill valve to the highest point in the system. In my Cape Cod house, with the boiler on the floor of my garage, the pressure gauge reads between 12- and 15-psi (the dial is too small to read more accurately than that).

WATER HEATING I - Dept of Mines Minerals and Energy

Indirect water heaters do not have their own heating source, but instead use the hot water from the boiler of the house heating system. The hot water from the boiler is circulated through a submerged heat exchanger in the water heater tank. When used in conjunction with a high efficiency boiler, this is one of the most efficient ways to heat water.
