We have a closed loop slinky system using 2 1/2 miles of special plastic pipe linked together to resemble a slinky.. buried 8 feet deep. Your installer should be able to advise you on whether a horizontal GSHP is right for your property. Now the other unit is out and I was told today that the unit needed replacement costing me $5800 because the manufacture discontinued that line and I would be require to make up the difference of the new unit. Depending on the size needed to heat and cool your home or business, installation can cost $10,000 or more. We have 360 ft. 4 lines out and in, and the seperation was about 3 ft. top to bottom. As seen in the illustration above, a ground source heat pump uses a considerable loop of pipe with liquid. It requires a lot more work because of the depth requirement, and is a larger cost. When you are going to spend this kind of money on a system, get an engineer to do the design. We have closed cell spray foam in the walls and open cell in attic along with all new energy efficient appliances, doors and windows. Ground source heat pumps are the most expensive of the heat pump systems.
The only comparison we have are houses similar to our size that have air source heat pumps with heat strips as the supplemental and there bills are the same as ours. This adds up to £15,000 for the drilling alone, which contributes to a £30,000 installation overall. We will be building a new second home & will have a well system like we currently have.New Construction(1994)2100 sq. I live in Washington state. Also, R22 insulation in main floor walls and R60 in attic.
The issue with horizontal GSHPs is that they use a lot of space and may not be feasible for properties with no large garden. So you want to install a ground source heat pump (GSHP) and wondering about how much it will cost? I had a problem with air getting in the loop and had to purge it a couple times. Then, the drilling of boreholes costs about The guideline for a borehole contributing 4kW to the heat system is roughly If we take the 12kW ground source heat pump, the total cost of installation can be around A study by the Department of Energy and Climate ChangeIt’s tricky to know whether boreholes or trenches are the best option for your ground source heat pump. Been in the house for 30 years and had always had an open loop system, 15 gpm from a well, and dumps into a lake in the back yard. A vertical borehole is used when less space is available and requires drilling to depths of about 100 metres deep. offers fantastic financial help with energy efficiency and the installation of renewable energy technology.Building your own home is complex. Traditionally, that would have meant adding electric resistance heating elements to the indoor air handler unit. you might need a 3-ton unit, or maybe a 2.5-ton unit, etc).Other home-related issues that can affect heat pump installation cost include:Many of the above factors can make the installation or replacement more labor-intensive for air conditioner contractors. This means it will cost more for an existing property than a newly built one. Therefore, with a 12kW ground source heat pump system, you will likely need to drill three boreholes.
Furnace compressor was noisy and gave us headaches. I finally added a home made expansion tank. Our electric bills have been very affordable. I installed a good quality universal blower motor.
Every home and every homeowner is different, so every job will have unique pricing based on the technician’s expertise. Be sure that your installer has experience in installations and that they are (at a minimum) IGSHPA certified. They were installed in 2011 and the first two years were great.
If used and installed correctly, they can save you money on your heating bills.
