Upfront Costs. Though they are less expensive to operate, electric heat pump pool heaters cost more upfront than both gas and electric resistance heaters. Heat pumps can cost up to $5,000, while the majority of gas and electric resistance heaters are available for around $1,000 and $2,000 respectively. The cost for installing heat pumps and gas heaters averages about $300 to $500, including labor and materials. The cost for installing an electric resistance heater can be two to three times this price because of necessary wiring upgrades to handle the required amount of electrical current.
