I have a gas apollo hydro heat system 50 gal water tank air handler system.
Hydro air heating system blowing cold air.
Here are just a few things that could mean.
Be sure the filter is circulating properly.
The air picks up heat from the coil and the blower fan moves the air out into the duct system which distributes it to your rooms.
Its only 3 years old.
Ensure that your thermostat is set higher than the temperature in your home.
There are many reasons an hvac heating ventilation air conditioning system might stop working.
The heat source in a hydro air system is a boiler generally gas or oil fired.
You re standing there pushing buttons trying to heat up the house but it s just not working.
A furnace blowing cold air could be due to your thermostat.
If you have a heat pump attached to the hydro air system it might be that the heat pump is preventing the hydro air system from firing properly.
Otherwise your electric heater or gas furnace will not turn on.
You may need to remove and down size the heat pump you keep attached to the system.
The air handler contains a pump hot water coil blower fan and in most systems an air conditioning coil.
The heater s blowing cold or the ac is blowing hot.
The upstairs unit is in the attic and the downstairs unit is in the basement.
A blower then sends air over the hot coils to push warm air into your ducts.
As hot water heats up the coils a blower then passes air over the coils.
I have a two story house split by two hydro air systems with hot water coils fed from an oil fired boiler.
A hydro air system is a combination of a hot water and a hot air system.
Hydro air systems combine water heating and air heating mechanisms into a single system.
Hydro air system blowing cold air after thermostat is satisfied.
Again using occam s razor we can assume that the next likely culprit for your heater blowing cold air is your thermostat.
Additionally the system can be modified to provide air conditioning.
1 dead batteries in thermostat.
As hot water heats up the heating coil the blower fan sends cold air from your rooms over the hot coil.
This type of system incorporates a hot water boiler either oil or gas fired which heats water and sends it through pipes to a coil in an air handling unit.
The perk of this system is that the air isn t as dry as with a forced air heating system.
You can hear it blowing but no heat is coming out.
These are properly known as hydro air systems which is a hydronic heating system combined with the power of forced air.
In this system an oil or gas hot water boiler heats water which is then is transferred to a coil in an air handling unit.
After the water is heated it passes into a small diameter tubing which takes it into an air handler.
