Gas heat pumps also referred to as absorption pumps operate in a manner similar to any air source heat pump with the exception that they use natural gas instead of electricity to power their operation.
Using natural gas as a fuel solution is effective but comes with its own merits and demerits when compared to standard products. This means as you shop around for the appropriate heat pump unit, you should consider a number of things including your location, temperature zone and efficiency rating of the system.
Understanding a Gas Heat Pump
Before comparing the gas pump with its alternatives, it is important to understand how it works. An air-source pump resembles a refrigerator where compressors and a series of coils move warm air in and out of your house. Even during winter, the heat pump can still capture a small amount of warm air from the outside and force it into the house. During summer, the reverse happens where the pump forces out warm air and pulls in cold air from the outside. Gas heat pumps on the other hand are operated using natural gas and make use of natural refrigerants such as water and ammonia. Essentially, air source, geothermal and gas heat pumps do the same type of work but the difference is in the way which they are run.
The Advantages of Gas Heat Pumps
Even though natural gas is a non-renewable fossil fuel, gas heat pumps have huge environmental benefits.
- Ozone-Friendly Refrigerants – Unlike electric units which use ozone-depleting refrigerants, gas heat pumps use environmental friendly refrigerants.
- Low Harmful Emissions
- It reduces electricity consumption which in turn lessens dangerous waste, occasional power surges and urban blackouts. Gas generated power burns clean and in relatively smaller amounts.
Demerits of Gas Heat Pumps
To avoid making costly mistakes, it is also important to look at the disadvantages of gas heat pumps also. The largest disadvantage of operating gas heat pumps is that natural gas is expensive compared to electricity. However, in terms of efficiency, all heat pumps are efficient and more cost-effective compared to electric air conditioners and gas furnaces.
Power and dependability are the two biggest complaints against all heat pumps including gas pumps. However, when compared to the other heat pumps, gas pumps have an output which is greater than the input making them more efficient and trustworthy throughout the year. When compared to geothermal units, gas heat pumps are less expensive to install and do not require a huge upfront investment.
From the above discussion therefore, there are some decisions to be made after going through the pros and cons of gas heat pumps. Generally, traditional air conditioners and furnaces do not match gas heat pumps in installation and operation. It is important to involve a professional HVAC expert when making this decision because they know the best model and pricing for various HVAC systems.
