Instead of being an agent for a particular manufacturer of Heat Pumps, we have decided to be an agent for YOU, so that we can offer you the best solution available when you decide to use a Heat Pump for cooling or heating your premises!
The cost of a Heat Pump will vary depending on the size your premises and the style you choose. High Wall mounted models are generally cheaper as they are in great demand. General rule a small heat pump, supplied and installed would cost around the $2500 mark inclusive of gst. The price goes up in increments of about $500 as the model's power output goes higher.
Heat Pump Efficiency... The beauty of a Heat Pump is that it has an input/output ratio of up to around 500%. Meaning, if you put in 1 kilowatt of power you will get around 5 kilowatts output. In money terms, it means 20 cents in every $1 returned. It's. Also due to the fact that heat pumps are fan forced, your space is heated or cooled within a very short time.
