Apollo Furnace/ Water Heater System
I have just purchased my first house and have an Apollo water heater/furnace system. It looks like the gas runs to the water heater and pipes run to the furnace and heat the hosue. I do not see any gas lines running directly to the furnace. I have not really been pleased with the system so far because it does not do the best at heating water and I am also not impressed with the way it heats the house. It says that the house is at 70 but there is no way, it is pretty cool in the house but I do not want to crank my thermostat up to 75 running up my bill.

Does anyone have any review on this type of system? Maybe how efficient it is or if it would be good for me to look into getting another system installed? I know the house was not lived in for awhile so I am curious if there is some type of furnace routine maintenance that should be done on it or anything on there that can be checked in order to maek sure I am getting the most out of it that I can.

Any tips will help!

Thanks a lot!

Got the model #?
The serial # most often will tell how old it is.
If it's really old a new one would be light years ahead on efficiency.
First thing I would do is call the service company to come clean it and check the flames.
Lots of times there a sticker from the last company that serviced it on the unit someplace.

I know it is 5 years old. I know it runs off the hot water so I don't even know if the furnace has any flames or how that system even works!

Since we have no pictures, no ser# or model # no one here will know how it works also.
There's some great HVAC people on here but there going to need that info.

these units do not have a very high outlet temp.You dont really have a "furnace" like you would normally think of one.
It is a fan coil that uses hot water from water heater.Water heater is usually a high recovery combo, like yours or
I have also seen unit use two water heaters.You can try turning temp up on W/H , but might want to have a tempering control
so you dont get scalading water at faucets.

Sorry such a late reply! Buut..would this be something I could have a company come look at to ensure nothing is wrong? Look to see if anything is going out in the system or whatever? I did turn the hot water up and I don't notice a difference except for like you stated extremely hot water.

It probably wouldnt hurt to have a plumbing/heating Co perform a seasonal cleaning and make sure circ pump in airhandler is working and it looks like there is also a zone valve in water line that can be checked.

Go and get a cheap but somewhat accurate thermometer, and place it close to your thermostat. it may be 70 in your house, but the humidity may be so low that it doesn't fell like 70.

HVACTCH96. I will definitely have someome come out. Thanks. What exactly is this valve you're talking about? I know a month ago I waa having issues with hot water and it ended up being someone but a mixing valve in.and it was closed all the way almost so I had to open it. I didn't get the purpose of the valve since you can control the temp of water with the water heater itself! Anyways...thanks for everyone's help.

It is an electricaly controled valve that appears to be on one of the lines going to the air handler.It opens on a call for heat.Probably installed to keep hot water from naturally moving to cold water when pump isn't running.

Alright...I have someone coming to look today. Thanks a lot!
