Carrier is rolling out a domestic split system heat pump with inverter technology as we speak. The system will produce nearly linear heating in a heat pump unlike all other traditional ducted heat pump systems. The result will be dramatically lower utility bills for heating your home.
Typical heat pumps lose capacity in proportion to the outdoor temperature. The colder it is outside, the lower the BTUH output of the heat pump. This drop in capacity can be graphed easily, displaying a curved performance. Typical of good design practice here in the Yakima area, we aim to have this curve match the heating needs of you home down to the 30-35 degree window. Below this window we get some help from a back-up source. If we do that we can reduce electric heating bills by 50% or more. The new Carrier Infinity™ unit changes all that.
Inverter technology produces heating capacity at a near liner output down to about 5 degrees. Thus the heat pump would carry the load not just to the 30-35 degree window, but down to approximately 5 degrees! In some cases the heat pump would then be capable of carrying the entire heating load with little or no auxiliary or back-up heat required. Carrier has taken the Inverter technology and developed controls and hardware into numerous patented produces they call Greenspeed™ Intelligence.
HSPF stands for Heating Seasonal Performance Factor. This is different that SEER, Seasonal Energy Efficiency Ratio, a measurement of COOLING efficiency ONLY. HSPF is calculated by taking the total BTU used during the heating season and dividing this by the total power consumed to produce that heat. Very typically the very best HSPF numbers have been within fractions of 10.0. Good units are considered 8.50 and above. Minimum code in our area is 7.5.
If you want to save money with your heat pump DO NOT use the SEER number to determine how well the heat pump will perform. Like the measure of miles per gallon in your car, the larger the HSPF number the better. If your heat pump had a 10.0 HSPF, you were in the elite few. Carrier's new Infinity™ heat pump completely changes that. The new benchmark is 30% higher at 13.0. There is not another air source split heat pump in the world that can achieve this efficiency. Not even close!
What this means to you is that if you had one of these more efficient heat pumps with an HSPF of 10, for every $100 you spent heating house with that heat pump, this new Carrier Infinity™ product would have provided the same amount of heat for $70. In comparison to many other lesser models on the market it could have done it for $31.
If saving you money heating and cooling your home was the only story here that would be enough. However, there is a great deal more! Heat pump performance is measured at two standard temperatures for analysis, 47° and 17° F. It seems every one knows the colder it is the less heat your unit puts out. So when we measure the heat output at 17° F we always find this much lower than at 47° F ambient temperature - until now! Preliminary test on the new Carrier Infinity unit for both the 2.0 ton and 4.0 ton units actually measure a RISE in BTUH output at 17°F. This is unheard of performance. The 3.0 ton and 5.0 ton units were nearly linear in performance from 47° F to 17° F.
See the graphic at the right. This compares the output in BTUH at 17° F for the most efficient comparable 3.0 ton units on the market today. No other model even comes close. While all the others are on the downward spiral at this point the Carrier Infinity™ unit does not dip below 25,000 BTUH output until 10° F.
What this means to you is that your new Carrier heat pump will continue to deliver comfortable warm air at dramatically lower ambient temperatures than other heat pumps. In fact the Carrier patented controls ensure leaving air temperatures to remain linear down to 5° F. Standard heat pumps just can not give you this kind of performance! Look at the Leaving Air Temps graphic to the left.
While other heat pumps are continuing that long standing problem of blowing cold air on you the Carrier Infinity™ unit will not. Note the dashed line of the standard unit. Even at the prime temperature of 47° F other heat pumps can't deliver the warmth of the Infinity™ system. This is a difference you will feel all the days you own your system.
The new Carrier product is available NOW. Yes it will be a more investment than a typical heat pump. However the price point allows for a high rate of return on investment, making the payback very attractive. Give us a call. We will be happy to consult with you about the benefits of this revolutionary new heat pump!
