Heat Pump Systems
What is a heat pump hot water system?
A heat pump hot water system is an electrical device that extracts heat from one place and transfers it to another, generally from its surroundings to heat water rather than to use an electric element to heat water itself. It is said to be more energy-efficient than the electric hot water systems.
What to consider when purchasing a heat pump water heater
The best way to describe a heat pump hot water heater is it is an air-conditioner in reverse, compressing gas to generate heat rather than cold. The hot gas runs through a coil of pipe that sits inside the water heater. It acts as an element transferring heat from the copper pipes into the water.
If you have a house that generates its own power or even runs off batteries, then heat pump hot water systems are the go-to product for you. Here are a few things to consider when purchasing a heat pump hot water heater:
How many people does my water heater pump need to provide hot water for?
Do I have solar thermal panels on my roof if I wish to have this type of hot water system?
Heat pumps work best outside. Do you have allocation outside where the heat pump will fit?
Heat pumps are noisier than electric or gas units except if you purchase those low-noise models. Our hot water specialists advise to ensure it isn’t next to your window or a neighbour’s window.
Pros and Cons of Heat Pump Hot Water Systems
Heat pumps hot water heaters use far less energy than traditional electric water heaters and work beautifully in conjunction with household solar.
Cost
The upfront cost of heat pump hot water almost costs twice as that of the traditional electric hot water. However, it uses about 66% less electricity than the traditional electric storage hot water system so operating costs are significantly lower.
Noise
The compressor makes considerable noise so it must be placed outside your home where it won’t disturb you or your neighbours. You will also need space for it to have enough airflow.
Environmental Impact
The heat pump hot water system works harder during winter months because the surrounding air does not have enough heat to work with. Since there is less electricity used, the emission of greenhouse gases is also reduced.
When should I have heat pump hot water heater repairs?
Here are some common problems when it comes to heat pump hot water systems:
No Hot Water
Before anything else, check if there is no trip in the power box where your heat pump is connected. If there is nothing wrong, the next thing to do is to inspect if the thermostat’s setting is set too low.
Rumbling Noise
There is usually a humming sound coming from your heat pump hot water system. However, if you hear unusual sounds similar to that of mini fireworks inside your hot water heater tank, this is caused by sediment build-up. It is important to flush your hot water twice a year.
Rotten smell in hot water
The reaction of tap water coming in contact with the anode rod, most likely once which is made of magnesium, can cause the smell of the hot water coming out from your shower to be putrid. The smell may even come close to a rotten egg. Replace it with an aluminium anode rod.
