Do plumbers repair hot water furnaces?

Hot water furnaces can be repaired by a plumber. Only a licensed professional plumber should handle the task, and he or she should be contacted immediately, as a damaged hot water furnace can cause property damage.


Can you turn the main water off and leave your furnace on?

This depends on the type of furnace system you have. A forced-air furnace should be completely independent of the water system. An older, convection-based (no pump) hot water system will have an expansion tank, and will not need to have the main water on, except to replenish the system, which should happen infrequently. A closed-loop system could possibly over-pressurize as the water is heated, with the mains valve closed, and would trigger the pressure relief valve, dumping a few cups of water every time the furnace cycles until the system was dry; eventually, with the pipes in the furnace dry, the furnace heat would melt and destroy them.


Can you turn off water to oil furnace and use an electric water heater in its placethe furnace supplies hot water and baseboard heatbut i have a pellet stove to heat the houseso i would like to use?

Yes you can do that. I had an oil fired furnace that also heated the hot water in a coil inside the furnace. I got an electric hot water heater and had a plumber disconnect the coil in the furnace and hook up the electric hot water heater. No problems after four years.


Can you turn off the water supply to the furnace for a few weeks and still get baseboard heat?

If it is a hot water system and not steam, once it is properly filled & bled of air no more water should be needed unless there is a leak. Regardless of whether it is steam or hot water it is a Boiler not a furnace.


How do you know the bladder in a hot water heating system is good?

If the bladder is bad in your expansion tank the tank will fill with water. When this happens the pressure in your furnace will exceed 30lbs and your pressure relief valve will blow off.

Why is there no pressure in your furnace for your forced hot water system?

=Possibly because a furnace is scorched air and a "boiler" is used for steam or hydronics==1-The loss of pressure could be a leak in the system==2- Incorrect setting on the automatic feeder==3- Improperly sized expansion tank=
