Heat Pump Hot Water

Heat Pump Hot Water Service and Repair

You may be thinking that they would only work in a warmer climate, with warm air to draw energy from. However, the way heat pump systems are designed is to extract warmth out of air anywhere down to -10 degrees Celcius, which means they are still a perfect option for those in cold climates. This is very similar to how solar panels extract heat and energy from the sun.

If you want to upgrade your electric system to a heat pump, you’ll be pleased to know they share the same connections, so this is an easy job for your local Metropolitan Plumbing professional.

How it Works: Heat Pump

Heat pumps use the warmth from the air and electricity to pump a refrigerant through a system in order to heat water. The refrigerant used boils at low temperatures (around -26^oC), allowing a heat pump to work at ambient temperatures as low as -10^oC!

Heat pumps heat your water in several steps:

A liquid refrigerant is passed through an evaporator where it becomes a gas. This gas picks up heat from the air.
An electric compressor is used to compress the gas refrigerant, causing it to increase in temperature even more. It is now hotter than the water in the tank.
This hot gas flows to a condenser and passes its heat on to the water in the tank, turning back into a liquid as it cools down.
The liquid refrigerant then flows into an expansion valve where it cools, ready to be used again.

While electricity is used to power the compressor and other components of a heat pump hot water system, they are approximately three times more efficient than electric water heaters with conventional elements. The warmer the outside temperature, the easier it is for the heat pump to warm your water.

How long does it take for a heat pump to heat water?

Whether it’s for your pool or just general hot water use, knowing how long it takes for your heat pump hot water system to heat your water can be useful. There is an array of factors which contribute to how long your heat pump will take to heat your water:

Water temperature
Outside temperature
Humidity
Wind
Insulation

Modern heat pump water heaters have settings which can be useful in swapping between energy saving settings and high-demand. In a high-demand mode, your heat pump hot water system can be fully heated in 60-80 minutes. Energy saving modes increase this time to 2-3 hours.

Are heat pump hot water systems noisy?

From the fan which sucks air into the heat pump, to the compressor which creates additional heat to warm your water, older heat pumps can be quite noisy. This is especially true if it has been installed near a bedroom where you need quiet. Modern day heat pump hot water systems, however, are only slightly louder than a whisper. Despite this, poorly placed older heat pumps have given this hot water system type a bad rap, and many people shy away from them because of this. If noise is still a worry, consider having your heat pump installed away from living areas such as bedrooms and living rooms to avoid noise being a concern all together.

What size heat pump hot water system do I need?

When looking at what size heat pump hot water system is best suited for your home, there are a few things you should consider:

How many people are in your home?
How much hot water do you use in a day?
What time of day do you use hot water?
Do multiple people use hot water at the same time of day?
Are there water-saving fixtures installed?
Does your dishwasher or washing machine use hot water?

Given that the average Australian uses approximately 75l of hot water per day, a family of four will most likely find that a 270-315l tank is suitable for their home. Depending on how many water saving measures your home employs, your storage tank could be reduced by as much as half of this!
