I had a friend who had a natural gas powered air conditioner, but I
doubt if it would pay to make it a heat pump. If you have natural gas, just
use it to heat the house in a forced air furnace.

Greetings,

I might be able to get a low interest loan from the government for the money
used to purchase the units. When the capital costs for the units are
artificially low sometimes it makes since to do things that otherwise would
not be economically sound.

Your tax dollars at work,
William

"As I understand it" heat pumps are more than 100% efficient in suitable
climates. Since furnaces are not more than 93% efficient, why wouldn't you
use natural gas powered heat pumps?

You only get over 100% efficiency for electric power, not gas.

That would be true only if electric motors are significantly more efficient
than gas motors. (and I haven't a clue if they are or not)

Greetings,

For the purpose of heating efficiency is generally measured as
BTU heat output / BTU fuel purchased.

You get 100% efficiency with vent-free gas heaters.
You get over 100% efficiency with heat pumps. The is because some of the
"BTU heat output" comes from the air outside of the house rather than the
fuel purchased. This is why over 100% efficiency is possible -- even with
gas.

Hope this helps,
William

The natural gas heatpump that I had some connection with did not use a
natural gas motor, only electric motors. It used natural gas for a source
of energy for the change of state. Note I believe they must use Ammonia for
the coolant and I am not at all sure if they would be reversible.

Greetings,

Neither electric nor gas motors are 100% efficient at converting electricity
or gas into mechanical energy. Electric motors are closer than gas motors
because gas motors give off more waste heat. In this case the "waste heat"
is usable so it isn't as much as a problem.

Hope this helps,
William

Obviously, what you really want to know is how much you are paying
to heat your house. The cost of gas versus the cost of electricity
determines which one is most economical.
In most areas of the United States today, natural gas is MORE
economical to heat their homes than heat pumps. Some geothermal
units are more economical on an energy used basis, but not enough that
the extra installation and maintenace cost are ever recovered.
