Real Home Success Story – Heat Pump Efficiency
Adding a heat pump to this home will increase heating and cooling efficiency
This is a real nice Manufactured Home Community. Well kept common areas and a manicured wetland in the middle. Wish it was a nicer day, 40 degrees and hit or miss rain rain showers. On the rainy days, I’m never sure what to do with my shoes when entering someone’s home. The shoes are basical clean, but I know it makes a good impression on the homeowner if I take my shoes off. Hope the carpets cleaner than my shoes.
The home I’m visiting today is a 1998 double wide manufactured home with 1200 square feet of living space. the home is heated with a Coleman 10 kW, 24,000 btu furnace. Fouteen months ago we added a new 13 Seer heat pump and honeywell 6000 thermostat to the home. Total cost of the heat pump, including permits and electrical connection, was $4,125.00. The local power company provided a $200 incentive, so the final cost was $3,925.00.
After 14 months of operation, we can check to see how the new system is saving energy and saving money. Let’s compare the months of December through March. In December 2008, the home required 58 kW/h ( kilowatt hours ) of juice, a year later, December 2009, 49 kW/h was used. January, 2009, 60 kW/h compared to 35.7 kW/h with the heat pump a year later. February, 58 kW/h went down to 35 kW/h a year later. And March, 50.7 kW/h down to 34 kW/h.
By adding a heat pump to the electric furnace, in this home, we achieved a 33% reduction in kilowatts hours used during the winter months of December through January. Of course, this little comparison does not take into account the difference in the weather pattern from one year to another, nor does it consider any variation in the way the homeowner lived in and used the house. As far as I know, the weather ways fairly normal and the people were consistant.
The extra advantage of the heat pump is whole house, forced air, summer cooling is now available. The people do not need to stuff two of their windows with window air conditioning units like they have done in passed years. Window AC units are efficient, but let’s face it, in order to install a window unit, the first thing you need to do is leave the window wide open all the time. When the AC unit is not in operation, it’s like having the window open - heat comes in and cool goes out.
Heat pumps have made great advances in efficiency in recent years for heating and cooling your home. Be sure to contact your power provider and your State Dept. of Energy before you choose a contractor to install a heat pump. If you are going to take advantage of incentives and tax credits for nstalling an efficient heat pump, you will probably need to use a qualified contractor.
