How Does a Heat Pump Heat?

Heat pumps are rising in popularity as people come to realize the extent of the benefits they provide. Their construction and method of operation allows them to provide a heat output equal to that of more traditional furnace and boiler systems, but with only a fraction of the cost. They’re both energy efficient and safe. How do heat pumps actually accomplish this feat? Read on to learn about the inner workings of heat pumps, and how they can provide such substantial advantages.

Heat Pump Anatomy

A heat pump is actually very similar to an air conditioner in terms of construction. There are two units, one installed inside the house and one outside. These units are connected by a conduit that allows them to share power, refrigerant, and any other resources necessary for operation. The most important part of this infrastructure is the refrigerant line, which is what makes it possible for the heat pump to actually move heat from one location to the other.

Heat Pump Operation

A heat pump is constructed similar to an air conditioner because it actually operates very much like an air conditioner. However, while an air conditioner will leech heat from the air inside the home and vent it outside, the heat pump does the opposite. When the thermostat calls for heat, the outside part of the heat pump begins to evaporate refrigerant using a coil inside the casing. This process makes the refrigerant gas into a heat sink, drawing the heat from the surrounding air and into the coil. The refrigerant gas, now holding the heat from outside, then travels down the refrigerant line and into the inside unit, where it is condensed back into liquid. This releases the heat to warm the air being circulated through the house.

Heat Pump Benefits

The way in which heat pumps heat makes them extremely energy efficient, because they don’t rely on any sort of fuel combustion to operate. All a heat pump needs to warm a home is thermal energy from the surrounding air and electricity to run on. Not only is this more efficient than heating systems like furnaces and boilers, but it is safer as well. Combustion systems produce a number of extremely toxic gases, which need to be vented outside of the home to prevent injury or death. Heat pumps don’t need these extra safety measures, because they don’t produce any toxic byproducts.

Just had an entirely new, full HVAC install done at our old house in Riverside, which was a fairly big job. Brian and... Will did the installation, and were awesome. There was going to be issues leveling the air handler in the attic, so they moved it to a new spot and hung it instead, getting new parts/changing the plan on the fly. We're much happier with this new setup and location of the air handler. I really appreciated this, their professionalism/thoroughness, and flexibility. Brian and Will worked super-hard, and double-checked everything once the job was done. Would use this company again.read more

Two installers here early this morning. Worked all day. Very professional, extremely well mannered and quick to answer... all my questions. They are Dustin and Robert. Both men went above just installing my new unit, they were personable and knowledgeable in what they were doing. I was surprised when I found out these two hadn't been working that long together. They worked extremely well together. I highly recommend this two men.read more

A snake crawled into my outdoor condenser and stopped my 16 year old Trane last week on Thursday. The power surge took... out my blower unit circuit board and the motor. I called J&W and Rob was over within two hours of my call. I was spec'd a new York 17 seer system and it was up and running on Monday. Technicians Jason and Brian arrived promptly and every facet of the installation was thorough. When completed, I would not of even known they were there except they left my garage cleaner! Thanks J&W!read more
