Furnace has water under it, why? Its a Dayton gas furnace.


There are several questions that need to be answered about what type of system you have, but i found this posting that may help:
As your gas furnace runs, is there water leaking at the base? Is the furnace's air filter wet, too?There are a few things that could be happening here. But if you have a high-efficiency furnace, here's the most common cause: a condensation leak.
We'll explain why a furnace creates condensation, and what's causing it to leak out of your furnace.
Note: You'll know if you have a high-efficiency furnace if:
  • The yellow energy guide tag says your furnace's efficiency is 90% or higher AFUE.
  • The vent/flue pipe is white PVC as opposed to metal.
Why a high-efficiency furnace creates condensation
How in the heck does a high efficiency furnace create condensation/water anyway?
It's all about how the furnace extracts heat from combustion gases.
A lower-efficiency furnace extracts some heat from combustion gases and then quickly vents them out the flue pipe.
But a high-efficiency furnace, to extract more heat, has 2 heat exchangers. These allow the furnace to extract heat from the gases for a longer period of time. This causes the combustion gases to cool and then condense.
That condensation then exits out your home through a drain. But if that water is pooling around the furnace, there's a problem preventing it from draining properly.
Causes of a condensation leak around a high-efficiency furnace
  • Clogged condensation tubing
  • Clogged condensation drain
  • Breaks in the condensation line
  • Issues with the condensate pump (if you have one)
You'll need a furnace technician to diagnose which of these is the issue and then fix it.
Other causes of leaking water around a furnace
If you have a conventional, standard-efficiency furnace...then its flue pipe may be incorrectly sized.
If you have a whole-house humidifier connected to the furnace...there may be an issue which is causing the humidifier to leak into your furnace. Your humidifier should be getting annual maintenance from a professional to prevent this.

Tip

2 Stage Furnaces More Comfort and Save Money


Two stage hot air furnaces can save you money and make your high efficiency furnace even better. With your furnace running at low fire instead of cranking up to the highest heating output in mild weather you can be more comfortable while saving money.

Many people think that they are getting the best they can get by buying a high efficiency single stage furnace. What they often don’t realize is that they could do better yet and for a few dollars more have a high efficiency 2 stage furnace that could keep them much more comfortable.


There are 2 stage hot air furnaces that are now available that will only run at half fire if the full fire is not needed. With a two stage furnace in mild weather when only a little bit of heat is needed, the furnace will have longer run times on low fire. This will keep you room temperatures from getting too hot before the thermostat reacts and shuts the furnace off again. This will help to keep your temperatures from overshooting the set point and help to keep your home much more comfortable.

Many of these two stage furnaces also have variable speed blowers that run at a lower speed when heating on low fire. This will also help to save money on your electric bill, because these blowers use very little electric when running at these low speeds. Air noise from the blower running at a high speed is also reduced.

If you are thinking of replacing or installing a hot air furnace, make sure that you ask your contractor to give you a price on installing a two stage furnace. The price difference probably will not be much higher than a high efficiency single stage furnace. However the comfort of the two stage furnace coupled with the electric savings will make the extra money well worth it.

Goodman Model GMV950905DX-an electrical surge burned out the transformer which I replaced, also replaced the circuit board. The variable speed furnace will no longer kick into high speed and it will l


If I remember correctly, there are dip switches on that control board that can be set individually. It is possible that it is just a setup issue. The switch positions should be explained in the installation instructions. I know that some Goodman and Amana two stage furnaces can be controlled by a single stage thermostat, but the dip switches have to be set properly. If the switches are set correctly the furnace will run in low stage heat for approximately 5 minutes and if the thermostat hasn't satisfied yet, it will kick in to high stage heat. I hope this points you in the right direction!

Anyone know about high efficiency furnace?


There is a lot of calculations involved in this. You need to know the sqaure footage of living space, the R value of the insulation, the construction type, size and number of windows etc.

Heater doesn't come on?


The electronic ignition system in a gas furnace is a modern development that allows more reliable performance than standing pilot furnaces, provides energy savings and contributes to better furnace efficiency (AFUE). With a standing pilot, found most commonly on older low efficiency furnaces (55% to 65% AFUE is not uncommon), a small gas flame is always burning and is known in the lexicon of American home repair as a "pilot light". The problem with this type of "analog" ignition is that it wastes energy by constantly burning gas and can sometimes be unreliable. These issues have led to the development of electronic ignition systems for mid to high efficiency furnaces that exceed the U.S. government's established minimum AFUE rating of 78%. The electronic ignition occurs typically in one of two ways:
  • Intermittent Pilot, or
  • Hot Surface Ignition The intermittent pilot system uses an electronically controlled high voltage electrical spark to ignite the gas pilot and then subsequently the main burners, when the thermostat calls for heat.
    The hot surface ignition system uses an electronically controlled resistance heating element not unlike a light bulb filament (and shown in the photo above), to ignite the gas burner.
    It is important to understand some of the other components of a modern furnace that you will encounter depending on the type of high efficiency furnace you have. Why? Because they can also come into play in repairing an electronic ignition furnace when it won't run properly. Let's take a quick review of the types of furnace designs and components found in high efficiency furnaces using electronic ignition.

    Do rinnai heaters run efficiently if turned up and down often?


    Maintaining the lowest acceptable setting and leaving it at that temperature is the most economical way to run the unit. If the space is going to be unoccupied for an extended time (several hours), lower temperatures are okay. This minimizes the need to burst the heat to warm the space quicker. As I understand your unit, it minimizes electrical & gas consumption by basing the need on the temperature difference of actual space temperature and setpoint. The larger the gap, the more power and gas is consumed.
    In summary, when the space is occupied, maintain a consistent temperature setting. When the space is unoccupied, maintain a lower setpoint.

    Hope this helps. Good Luck. :-)

    What is the efficiency rating on the Trane model BLU055E936B1 upflow furnace and what new furnaces are available to replace this old Trane furnace without having to change the venting system.


    Chances are you need to replace both the condenser and furnace, then you you should get a varaible speed blower with the new furnace, get at least a 90% gas system with a 16 SEER condenser, save on energy cost as soon as it's installed. Go Get IT

    Goodman furnace may be producing to much water


    Your furnace is more than 90% efficient and extracting so much heat from the gas that it condenses instead of blowing out steam. This is good! Figure that for every dollar you spend on fuel, you are getting back 90+ cents back in heat. Compare that to the typical units that only get 70 - 80 cents back in heat.

    Yes you should drain your condensate to a proper drain via gravity or a condensation pump. I would recommend you treat the condensate first with a acid neutralizer prior to draining in municipal drains due to it's high content of sulfuric acid. You can purchase these filter type neutralizers on the net or at a good heating wholesaler.
