The Energy Efficiency Conservation Authority (EECA) Government agency has acknowledged heat pumps as one of the most energy efficient ways to heat your home. A correctly sized and professionally installed heat pump can produce up to 4 or 5 times more heat for each unit of electricity than a conventional heater.
Low Running Costs
While the initial investment in purchasing and installing a heat pump may be larger than purchasing a smaller conventional heater, the overall running costs are much smaller and the long term savings much greater as heat pumps only require a small amount of electricity to run.
Many conventional heaters and wood burners only provide spot heating and don't evenly distribute heat around the room. Because heat pumps include a fan, the warm air is spread more evenly. Once your set temperature has been reached, a heat pump will maintain that temperature meaning the room will stay comfortably warm - not too hot or too cold!
Gas heaters and other heating appliances which burn fuel produce carbon dioxide and fill the inside air with moisture, creating unwanted dampness and humidity. Heat pumps usually feature a 'dry' mode which combats excess moisture and will help prevent indoor condensation problems.
Heat pumps filter the air drawn in from outside the house, getting rid of allergens and pollutants before they air circulated inside. Advanced air filtration systems in modern heat pumps filter and deodorise incoming air to remove microscopic airborne particles that affect asthma and allergy sufferers.
Heat pumps provide instant heat at the touch of a button. There is no waiting for the element to heat up and no manual labour involved in feeding or topping up firewood. All modern heat pumps also include an automatic timer, meaning you can easily set up the unit to warm the house to the ideal temperature before you wake in the morning or before you return home in the evening.
Cooling in Summer
Heat pumps are perfectly suited to New Zealand's temperature difference between summer and winter, as they also provide cool air in summer. Overseas consumers would call a heat pump an air-conditioner, as they perform the same job only in reverse. During summer, heat pumps can be set to air-condition your home by extracting cool air from outside and pumping it indoors.
