Heat pumps

Heat pumps definitely have their benefits. They run on electricity, which makes them much more environmentally friendly than some options. Because they don’t use as much energy as some heating systems, they can be an efficient and cost-effective choice. Plus, their use isn’t limited to heating a building — they can also keep it cool over the summer.

Central heating

Central heating, especially central ducted systems, can heat or cool an entire home with up to 500% efficiency. This type of system remains popular in New Zealand for several reasons. Firstly, it is highly energy efficient, particularly with modern systems. Additionally, it allows for precise indoor temperature control, which helps save both money and energy.

Can central heating cause health problems?

You might have heard that central heating can cause health problems, such as dry eyes and sinuses. However, you can avoid this by making sure you don’t overheat the room — somewhere around 18 degrees Celsius is comfortable for most people, so try to stick to this temperature. We make sure there is  the right amount of air in your room to provide unobtrusive heat, The comfortable temperature will be your only indication that the unit is heating

Which is more efficient?

While both heat pumps and central heating are efficient in their own ways, Central heating systems come with thermostats that allow you to control the temperature, meaning you can decide how much energy is used at certain times. Central heating is also relatively inexpensive to maintain, so if you want central heating might just be easier to use efficiently. to boost your energy efficiency and keep ongoing costs low, central heating is definitely worth considering.
