Hot water heat pumps are giving New Zealand residents a more sustainable and efficient way to heat their water. By taking heat from the surrounding air, a hot water heat pump need less energy to create hot water than traditional heaters. If you\u2019ve been wondering \u2018Are hot water heat pumps worth it?\u2019, allow us to answer your question with a resounding yes.<\/p>\n\n\n\n
Put simply, and as touched on above, hot water heat pumps<\/a> absorb heat from the air around them. This heat is then transferred from the pump to a refrigerant fluid where it evaporates and turns into a gas. After this happens, the temperature of the refrigerant increases and so transfers heat to a heat exchanger which finally passes to the water. The condensation process will then occur and the whole process can start again.<\/p>\n\n\n\n Let\u2019s work it out in terms of efficiency. The best way to work out the efficiency is to look at something called the Coefficient of Performance (essentially the ratio of how much useful heat it produces to the power input). The higher the number, the more efficient.<\/p>\n\n\n\n We already know that heat is extracted from the air instead of through gas or electricity. This makes a huge difference. It\u2019s generally accepted that they have a COP approximately 4 times higher than a standard electric water heater! Not only is this good for you and your energy bill, but it\u2019s also good for New Zealand and the world.<\/p>\n\n\n\n Hopefully, we\u2019ve left you with no need to wonder anymore \u2018Are hot water pumps<\/a> any good?\u2019.<\/p>\n\n\n\nWhat does this mean for the future?<\/strong><\/h3>\n\n\n\n
