No heat from heat pump in Home Repair & Improvement http://www.dslreports.com/forum/r21492185 en Sun, 06 Dec 2009 02:26:17 EDT Sun, 06 Dec 2009 02:26:17 EDT Re: No heat from heat pump http://www.dslreports.com/forum/remark,21492702 Hydraglass : My previous house had a very nice heat pump - it just wouldn't work below 30F - the air was just as cold as ambient - maybe 1 or 2 degrees warmer. It was plenty large enough - the A/C unit could cool the house 10 degrees in an hour, and when the outside ambient temps were 40F or warmer it could heat the house 10 degrees in an hour. ]]> http://www.dslreports.com/forum/remark,21492702 Thu, 27 Nov 2008 10:47:18 EDT Re: No heat from heat pump http://www.dslreports.com/forum/remark,21492684 owlyn :

Out of curiousity, what is the outside temperature at your location? If it's around or below the freezing mark, your heat pump pretty much can't extract any heat from the ambient air and will just blow cold air - and you have to use the supplemental electric heat.
I don't know where people get this idea. Well, I do, actually. Builders cheap out and put in an undersized heat pump, and then people think that heat pumps don't work. It depends on the heat pump. Mine works to about 22 degrees before the aux heat kicks in. A properly sized heat pump is very efficient. ]]> http://www.dslreports.com/forum/remark,21492684 Thu, 27 Nov 2008 10:42:39 EDT Re: No heat from heat pump http://www.dslreports.com/forum/remark,21492614 Hydraglass : At 48 degrees, your heat pump should be able to pump out quite nice warm air - at least 5-7 degrees above ambient - so I would suggest calling your favourite HVAC tech and have them come check your system - could be stuck valves and you really are "A/C" instead of "Heat" even though you think you're on "Heat".]]> http://www.dslreports.com/forum/remark,21492614 Thu, 27 Nov 2008 10:27:20 EDT Re: No heat from heat pump http://www.dslreports.com/forum/remark,21492591 anon : I've never liked heat pumps for that reason, give me good old fashioned forced air heat!

To answer your question, yesterday when I tried experimenting with it, it was about 48 outside.

I like it cool and really have not turned the heat on. The basement has baseboard heaters and other than sleeping and cooking I've spend most of the time downstairs. The few chilly nights I've had a fire in the wood stove upstairs. But this week with relatives staying I've resorted to the heat pump for upstairs heating.]]> http://www.dslreports.com/forum/remark,21492591 Thu, 27 Nov 2008 10:22:12 EDT Re: No heat from heat pump http://www.dslreports.com/forum/remark,21492494 Hydraglass : Out of curiousity, what is the outside temperature at your location?

If I leave it in standard heat the compressor outside does startup and run but all I get is cold air from the vents, in-fact it almost feels like the A/C is running.

When I flip the thermostat to emergency heat the compressor does not run but the house heats up fine. The A/C worked just fine this past summer.

The heat-pump is only a couple years old and was manufactured by Janitrol as is the thermostat.

Anyone have a suggestion so I don't go broke paying the electric company. I'm fairly handy with a multi-meter.

Thanks -- Happy Thanksgiving]]> http://www.dslreports.com/forum/remark,21492185 Thu, 27 Nov 2008 08:24:05 EDT
