Question:

Hi Tim,       Would that not be the same as the A coil used in the Air to Air exchanger as it is filled with coolant as well. Thank you for your reply. gustaveous

It seems to me the only difference is the piping you sink in the ground and the pump to drive the coolant through the pipes. Gustaveous You are correct. You need a refrigerant to water heat exchanger and a pump tp move the water through it. http://www.energy-miser.com http://www.fhp-mfg.com

Some of the reasons people are running these alot more than necessary is that they are using programmable thermostats.  Something not recommended with a heat pump.  You must be aware the a couple of degrees difference is going to beg for emergency heat when you program up and down. We highly recommend that heat pump stats be set at one constant temperature and use an autochangeover stat for summer a/c.

There are now programmable thermostats made especially for heat pumps. They raise the temperature gradually so the backup heating system does not kick on. Rick Marinelli

Would like to hear recomedation on heat pumps we need to replace ours. Thanks for the help.

Response:

I’m looking into ground source heat pumps, sometimes called geothermal heat pumps.  Please look at the thread on alt.home.repair. I understand they are more money to install, but require a lot less energy to run.

What part of the country do you live in?  Heat pumps are an excellent choice over electric furnaces but are probably not as efficient as a gas or oil furnace.  But once again it depends on what part of the country you live in. WE are over here in south Texas and heat isn’t real important but that may not be the case for you.  If you have any questions give a call. Ginther Sales Inc. 1301 E.

Heat pumps are generally MORE efficient than gas or oil.  However efficiency doesn’t equal low cost.  The cost of btu per gas is so much lower than electricity that I can afford to throw away some efficiency.  My energy bill dropped substantially when I converted from a heat pump to a gas furnace. However, here in the NE you also have to take into consideration what backup you have for days when the heat pump can’t hack it. Resistance heating is about the worst (but the most common) way of doing it.

Ron Heat pumps ARE MORE efficient than gas or oil and we are not burning/wasting our resources of fossil fuels.  The cost of BTU per gas is generally NOT lower than electricity.  Many utility companies and cooperatives have programs in place for geothermal at reduced rates. I have been in geothermal for over 10 years and have around 1,000 installation in place.  Michigan has very cold climates to deal with and we don’t have any problems with our installations. I’m not sure why your energy bill was a lot lower with gas – generally heat pumps are 15-20% less than natural gas in cost.  They are also 300% more efficient than natural gas. A heat pump can’t hack it?  What kind of heat pump did you have installed? When sized correctly, and having the duct work sized for 130% return air – heat pumps more than just hack it!  Most heatpumps come with 10KW or 15KW emergency heat modules built in.  Some of the reasons people are running these alot more than necessary is that they are using programmable thermostats.  Something not recommended with a heat pump.  You must be aware the a couple of degrees difference is going to beg for emergency heat when you program up and down. We highly recommend that heat pump stats be set at one constant temperature and use an autochangeover stat for summer a/c. Also, you don’t mention whether you were on an open loop or closed loop system. There’s a difference in operating costs.  Loops are buried 4-5 feet down — ground gets cold in the winter – loops can get down to 17 degrees (loop contractors won’t tell you that!).  Loops are 15-20% less efficient than an open loop well water & discharge (pump & dump) system.  Ground water is a constant temperature all year around (45-55 degrees F). If a heat pump was running all the time and costing you quite a bit, there are a couple of scenarios:  not sized correctly, programmable stats, totally inadequate duct work, etc. etc.  Don’t forget how the home is insulated! Air infiltration and heat loss are additional factors generally not taken into consideration. If you want more information re: geothermal and it’s efficiency – go to GeoExchange on the internet.  When a heat pump costs more to operate over fossil fuels, something is definitely wrong! Sorry you went back to gas!

Hi Mark Fenley, hope you are having a nice day 19-Sep-00 07:34:23, Mark Fenley wrote to All  MF Purchased my new home about 4 months ago, our first home.  It has a  MF heat pump installed.  In my old house, I had purchased a programmable  MF thermostat for the ac/heat.  I was thinking about getting another  MF one, but when I looked at a couple at HD this last weekend, the ones  MF I picked up and read the package said that they were not to be used  MF with heat pumps.  Is there a programmable thermostat that can be  MF used with a heat pump?  Any info would be greatly  MF appreciated…..Thanks in advanced…. There are programmable stats made for heat pumps but whether or not you will save money depends on what kind of backup heat you have. if it is electric and you live in a colder climate it is better to set the tstat and leave it at the same temp all of the time. when you set back it allows the backup heat to come on when it tries to recover and this throws everything you saved out of the window when it is electric backup. but if you have a hydro or forced air backup this works fine. .. But I thought YOU did the backups…                                       ___ TagDude 0.92
