Invictus, meaning unconquerable or undefeated in Latin, is a poem by William Ernest Henley. The poem was written while Henley was in the hospital being treated for tuberculosis of the bone, also known as Pott's disease.
Expect to pay as much as $5,000 to $7,500 for a ground-source heat pump system. Air-source heat pumps can be found for much cheaper, averaging around $1,500 to $4,000, because the units tend to be simpler, and installation is easier. The cost required to run and repair a heat pump varies with the type of system.It's less expensive to run a ground-source heat pump because the ground and water have a relatively constant temperature that allows the heat pump to operate efficiently.Ground-source systems also have the advantage of not being exposed to the outdoor weather, which prevents a lot of wear and tear.xpect to pay as much as $5,000 to $7,500 for a ground-source heat pump system.

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).
