The same principle applies to gas engine heat pumps as it does to electric heat pumps. Within a recirculating refrigerant, they transport heat into and out of the home. The heat pump's compressor in the exterior unit is powered by a natural gas engine rather than an electric motor.
Unit&Installation Costs
Before you invest, think about the advantages and disadvantages of gas heat pumps. Labor and standard materials for a 3-ton system run from $5,000 to $8,200. The larger the capacity of your pump, the more you'll pay. Don't try to save money by installing one that is too tiny for your requirements. With a system that operates constantly, you'll quickly lose your original savings.
Running Costs
Natural gas heaters (sometimes referred to as NG heaters) require around 1 therm per hour per 100,000 BTUs. That's 4 therms per hour for a typical 400,000 BTU pool heater. Natural gas costs roughly $1.50 per therm near Tampa right now. On average, it costs roughly $7.00 to heat a pool for one hour using natural gas. An ordinary pool (10-12K gallon) with no solar cover takes 8-14 hours to heat.
Service Costs
The cost of a technician visit will be determined by your particular heat pump supplier. However, there are two types of technician fees: A general service call will cost between $50 to $180, plus an hourly labor charge of $80 to $160.
Replacement Cost
Replacement costs average $3,700 to $7,900, although certain pumps can cost as much as $25,000 or as low as $2,000 to install.
Is it Worth?
Gas heat pumps operate similarly to other air-source heat pumps, except they use natural gas instead of electricity to power their function.
