1st winter with geo-thermal heat
I am in upstate NY. 1st winter with my system. Installer out of business because of fire. Have another dealer coming next week to familiarize himself with my installation for any future warranty/service work needed. Thought I would ask you folks what to expect. I have 2 waterfurnace envision units on a closed horizontal loop. Currently, considering wind chill, it is about 5 degrees outside. Both units are running at stage 1. They run for about 30minutes, and shut off for 7-10minutes. keeping the temp at 71 degrees. I assume that since they are staying in stage 1, things are doing fine. Given the outside temp, is it " normal "for them to run nonstop for 1/2 hr. Thanks for your help. RS
Sounds like you probably have oversized units. During the heating season this is perfectly ok. In fact, my system sounds pathetic compared to yours. If I don't keep my woodstove running pretty hot, I'll pretty much run nonstop on stage 1 and even dip into stage 2 from time to time to keep my house at 71 (when it's that cold outside).
Just for curiosity's sake, what size are the two units, and can you tell me a little about your house?
Based on the information you provided, we do not have any concerns with your equipment.

i see new installs run much longer than that.
Envision working great.
I have been servicing water fnc equipment for over 20 years in Lancaster PA and it sounds to me like yours is working great. I am surprised that the stats are satisfying with just low stage operation on such a cold outside conditions. Your home must be pretty well insulated and air tight or the units are a little oversized. Anyway, enjoy one of the best hvac units on the market today. Yes,I am a little biased. Brian.
First winter with high electricity bill.
We just moved into our new house with an envision geo-thermal heating unit, 5 ton system for a 2300 sq. ft. ranch house in Central PA. Our first electricity bill was $410 for December, today we got the bill from Dec. 24 to Jan. 25 and it was $379. I am shocked! Is this normal? We keep our house pretty much at 64 the whole day, in the evening we start a wood fire to heat the house up to 70. Our unit pretty much runs on stage 1 for about 10 minutes at a time, off for about the same time. How do I know if the auxiliary heat come on? I have an intellizone control panel. Any help or suggestion?
elect. bills normal?
There are too many unknown factors for me to say if your bill is too much, just right, or cheap. For example. Is your home total electric? What are your utility rates? How well are you insulated? What is you anticipated heating load calculation? And many more. A good way to figure your heating cost is to take a non-hvac active month like Oct. or April and use that as a basis for electric use. Then take your avg winter bill and subtract the basis month. This leaves you with an approximate heating cost for that month.
The best way to know if your Intellizone control is asking for aux heat is to look at the outputs on the upper right hand side of the board. If there is a green led lit up next to the "w" output then the board is signalling the aux heat to turn on. I do not know how many zones you have but be aware that just because a stat shows that it is calling for aux heat does not mean that it is on. It only means that the stat is requesting the intellizone to turn it on. It usually take appox 75% of the total possible demand from all of the stats combined to cause the intellizone to turn on the aux heat. There is one exception to this rule and that is if the installer turned on an option on the intellizone board called faster upstaging with timer. If he did then the intellizone is forced to turn on a higher stage after so much time has expired. Ask the installer if he turned this on. Does not sound like you need it. Hope this helps a little.- Brian.

If your all electric thats awesome......omg. This includes all heat? hot water? cooking? Lighting?
An oil heated home you size will use 200 gallons of oil and $200.00 in electric a month. Thats $900.00 a month.

More details on the house
We moved into this brand new house in November, so we only have two month worth of electricity bill. Our house is only electric, so everything runs on electricity. All our appliances are brand new, energy star qualified. The only old thing in our house are 2 old TVs from about 2000.Our utility rate is 12.97 cents per KWH, total rate ($371/2861KWH used = 12.97). Our house has an unfinished basement and an unfinished full attic. We have insulation of at least R38 in the attic, at least R30 in the ceiling of the basement and at least R19 for the walls. All insulation is fiberglass mats. All our windows are w/Argon triple glazed, doors are w/Argon double glazed. Our house faces East with the side of the house facing South. We do get lots of evening sun, but the house is on a hill. I hope this helps. Am I being paranoid about the cost? The installer told us that similar houses in our neighborhood with geothermal have a total electricity bill of $200 in the winter. Did he not tell the truth?
Cost is all relative ...
WAY TOO High .. my electric bill for all electric 1,800 sq feet is running $50 / month for last few months.
