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.eat 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.

As you can see, running the Heat Pump costs less than half of the price for producing the same amount of heat of an Oil fired heating system, and makes it a very viable option for those with LPG or Oil based systems.ompare this to an average cost of 11kw worth of hot water produced from an Heating oil powered central heating boiler, which would cost 61p per hour to run, or Â£4.93 for an 8 hour ârunning periodâ (based on 56p per litre for oil).
