A: According to a Washington State University study, a DHP is about 3X as efficient as electric base board heaters, and up to 30% more efficient than ducted heat pump systems. The computerized inverteris the reason a DHP runs on a 15 or 20 amp circuit instead of the 70 or 80 amps (on start up) that a conventional heat pump draws in the continuous on/off delivery of indoor heating or cooling. That is less than what some flat screen TVs run on.
Q: How much can I save on heating costs with a DHP?
A: When correctly sized and installed the monthly savings range from 30% to 80%. These savings will vary depending on factors such as where you set your thermostat, how energy efficient your home or office is to begin with, and whether you upgrade every room with DHP technology, or just one main room. Furthermore, the less energy-efficient the construction of your building, the more an upgrade to ductless technology will save you, month in and month out. Thus older homes, sun rooms, that drafty cabin, or vacation home are some of the best candidates for a DHP upgrade.
DHP applications to fit your lifestyle are:
- Keep that bonus room above the garage, basement, studio, or office comfortable only when in use - Customized systems for new construction projects - Air filtration, especially helpful for allergy sufferers and the immune-compromised - Dehumidify moisture-challenged conditions - Eco-friendly R410A refrigerant has zero 'ozone depletion potential'
Are there any other advantages to having a DHP?
- DHPs are safer than in-window air conditioner units which offer an easy entry point for intruders to enter the home, or office. - They are whisper quiet, and indoor units run as low as 19 decibels at low speed, and up to 49 decibels at high speed.
Q: What is the cost of a DHP installation?
A: The price of a DHP installation is determined when we come out and do a free estimate that is based on the construction of your home or office, as well as the size and model of DHP that is most suitable, as well as the number of outdoor compressors and indoor air-handling units needed.
Q: Are there financial incentives for a DHP upgrade?
A: There is easy financing available with Energy Smart Loans at Puget Sound Cooperative CreditUnion (1-800-273-1550) for DHP remodeling and addition upgrades. PSCCU can offer customers a 4.49% interest rate, and payments as low as $50 a month. This means that upgrading to a DHP can save you more on your heating coststhan your loan payment runs. So you may be little to nothing out-of-pocket when financing the installation of a DHP.
Most Public Utilities , including PSE, are offering their customers a rebate of up to $800 to retrofit your home with a with an energy efficient ductless heat pump system. The reduction in demand for electricity benefits you and the utility providers (who won't have to build as many new power stations to meet the growth in demand).
Details to consider: - Careful calculations are done for a room by room assessment to determine the size of DHP that meets the combined load of all heating/cooling zones. - More than one outdoor unit may be necessary for multi-zone systems. - The outdoor units can be placed a significant distance from the indoor units, and out of the way. - The insulated line-sets require a 3 inch hole be cut, through which they can enter the building.
Q: How soon can I get one installed?
A: Energywise can usually schedule your installation within 10 days, and for single port installations, it takes 1 to 2 days to install. For bigger jobs, a sophisticated installation can take more time.
Q: Can I install a DHP myself?
A: Not if you want a warranty. You would also, most likely, end up needing assistance with the charging of the refrigerant into a vacuum and the start up procedures, which take specialized equipment to achieve. Also, using refrigerant products requires training and licensing.
Q: What is the warranty?
A: The warranty on select Daikin systems is 12 years. Otherwise it can vary from 7 to 10 years for compressors, and 5 years for parts. Energywise DHPs offers a 2-year workmanship warranty on our original, unaltered residential installations, and provides a free service check at the end of the first year of operation.
Who do I call for technical assistance?
Q: This technology is very reliable, and easy to operate. Should you have any questions though, please feel free to call us at Energywise, at (360) 661-7191.
Do I need to clean the unit?
A: Yes, the outdoor unit should be kept free of debris. The indoor air handler has a washable filter that will last for years, and is easy to remove and clean every month or so with water, or can be cleaned with a vacuum.
Caution: When cleaning the filter, be careful not touch the finned heat exchanger. The fins are fragile, and can be damaged. Call or email if you have any other questions.
