Hello

[Myoungmike]

Hello everyone, I'm new here. I have been reading for a few weeks, I have a ground source heat pump that I have been running for about two months now, and it is working great.

I'm not much at doing online posts... but I will try.

Welcome to the site.

Its great to hear you have a heat pump. Can you tell us a bit more about the house?

[Myoungmike]

I will start with a quick rundown of the house...

Built in 1967, two story colonial, five bedroom, six bath, with walk-out basement, now about 5184 sqft of heated space, all radiant infloor.

I purchased this house in January 2001.

Started to digout crawl space by hand spring 2001.

Roof redone summer 2001
Old hard board sideing removed (what was left of it) summer 2001, 3/4" r-max insulating board added to most of outside. All 33 windows replaced 2001.

Sofit and facia (about 250') replaced winter 2001.

New underground electrical entrance summer 2002

800 sqft of wrap-around porch (roof only concrete added a few year after) added summer 2002.

Sided summer 2002.

New laundry/mud room floors, removed some walls and entrance door fall 2002

Added cellulose insulation in attics winter 2004.

Repaired rotted kitchen floor and lower cabinets winter 2005 or was it 2006...

Poured patio slab summer 2006.

October 2008 removed about 25' of basement wall to add windows and french doors to get daylight into basement. Also to be able to drive bobcat in/out to finish digging the crawl space (about 650 - 700').

November 2008 replace sagging/twisted beam, and added an extra beam.

December 2008 moved out of house project is now a money pit...

Winter 2008/spring 2009 found major cracks in chimneys, at the same time boiler died. Removed all three chimneys, and both fireplaces. Both were one good fire away from a very large fire!!! Stripped walls to studs, fir'ed out to 2x6 and intalled R-19 insulation. Removed and moved many interier walls, added many LVL's, rewired, new sheetrock, new hardwood floors, installed radiant heat in floors.

Spring 2009 repoured basement floor (20 yards of mix). When we were getting ready to tie the plumbing back in we did some cuts with a demo saw, and parts of the floor collapsed. We fould parts of the floor that were only 3/4" thick, and not any thicker under some of the jack posts! We dug new footers for the posts, and insulated the floor and did an over-pour over the old floor, couldn't remove old floor becauce it was the footer for block walls. I did lose 4" of head room but sill have about 7' ceilings.

Moved back in July 2009. Reused kitchen cabinets. Bathroom in basement in use, others under construction...

Winter 2009 Tried to heat house with a 30000 btu gas heater...

Spring 2010 finished tile in kids bath/laundry room, tiled mudroom, and foyer...

Summer 2010 installed new kitchen, kids bath and master bath cabinets, and counter tops.

December 2010 finished install of Econar Ultra, 7 ton GSHP open loop...

January 2011 install new well pump. Rented mud pump to remove foot mud from bottom of dug well. Had leak in water line from well to house, needed to run pipe above ground last friday, just before the real cold weather hit (temp down to -25 f).

Well has been running nonstop at 12-13 gpm for a week now.

Thats the quick rundown of my house...

I'm confused...

You installed radiant floors, heated house with 30,000 BTU gas, then started using 84,000 BTUs from your Water Source Heat Pump to heat the same house?

I sould say that we tried to heat the house with the gas heater, very cold basement, and 2nd floor, 1st floor was OK (64-68 F) most of the time except when the temp was in/or below single digits... The plan was to have the geothermal working for the 2009, but with everything else going on it just got moved to the back burner.

My heat pump has been running for a year now, and my electric bill for the last 12 months was $1400 more than the prior 12 months. No gas heat used, and no fuel oil. I was burning 1400 - 1700 gal. of oil per year, and the house is much more comfortable.

Also installed a HPWH, and am very happy this the costs to run. Looks like it will save about $300 - $400 per year.

Wow thats an impressive amount of work. Huge house. The amount of furnace oil you went through had to be a killer. Is the basement walk-out in-floor heated? Where you planning any solar input?
