Quantum Heat Pump FAQs

Frequently Asked Questions about the Quantum Heat Pump are covered here.

What tank sizes are available?

The 3 sizes available are 125 L, 175 L, 250 L and 315 Litre. A one or 2 person home might select a 125 L tank, a 2 to 4 person home a 250 L tank and a 315 L tank for larger families.

Do Quantum water heaters require a booster?

Depending on the model, the Quantum can deliver 600 L to 3500 L of hot water a day without electric or gas boosting elements. Quantum's patented technology is world-class and delivers the fastest heat recovery rates for their size without any boosting being required.

Will they work in bad weather in cold weather?

Yes, a Quantum will work all year round without a booster element. Even in very cold weather, as the evaporation temperature of the liquid refrigerant is well below 0 degrees (-28°C)  its will still absorb and transfer heat to the water tank, even when the air temperature gets to -10°

Could the system get frozen in winter?

No!  Unlike solar collector systems which can rupture when water expands within them when it freezes a Quantum heat pump has no water filled panels or any panel at all.

Will I ever run out of hot water?

A heat pump hot water system is designed to deliver large volumes of hot water. However, as with any gas or electric water storage tank, if completely drained of hot water in a short period, a heat pump's water storage will require time to recover, usually no more than 3 to 4 hours.

Could I be scalded by the hot water?

The Quantum heat pump is designed to heat your water to 60°C and is thermostatically controlled and cannot overheat even on a hot summer's day. Plumbing regulations require that a tempering valve be installed between your heat pump and your tap to moderate the hot water usually to 50°C to reduce the chance of scalding.

How long as it take to heat a fall tank of water from cold a hot?

With an outside air temperature of 20°C the heat pump will run 3 to 4 hours to heat a full tank of water to 60°C based on a 270 L tank

We use the most hot water in the evenings. Will be plenty of hot water 1st thing in the morning again?

Yes! Even on the coldest winter nights a Quantum hot water heat pump will recover for use by early in the morning.

How much energy is required to heat a full tank?

Around 3 - 4 kWh of energy will be used in  heating a full 270 L tank from cold to hot. An off-peak electric hot water heater will use 4.8 kWh over 4 hours per 270 L, which is 19.2 kWh of energy for the same amount of water!

If I live in a seaside location will salt spray have an effect?

As the heat pump is made from metal, highly salty atmospheres can be detrimental. Although the evaporator has a special treatment against this, it is wise to position the heat pump to avoid salt laden air where possible.

Can excessive moisture around the base of the unit be a problem?

Good plumbing principles apply. It is important to avoid buildup of moisture around the base of the unit to reduce the chance of rust. Correct drainage of the collected condensation from the evaporator away from the unit is also required.

Where is it best to place the water tank?

In most cases,  the all in one heat pump and water tank unit will be placed outside. The tank's outer casing is ColorBond coated zincalume designed to operate outside. In split systems, the water tank can be located inside or outside. it is possible to install the unit in an area like a double garage, as long as there is plenty of air volume of at least 120 m³, but in more confined spaces the cold air expelled from the heat pump would reduce its efficiency.

On a split system model how far can the evaporator be away from the water tank?

Generally, 9 m or less of pipework between the evaporator unit and the storage tank will allow the most efficient operation of the system as well as allow the proper looping of lubrication oil back to the compressor.

Is it a steel water tank? Does it have corrosion protection?

Yes, the tank is constructed of high-grade mild steel with a vitreous enamel lining. The tank is further protected with a sacrificial anode which further protects the tank from corrosion due to hardness or impurities in the water supply. Since there is no copper booster element, there is no electrolytic action with the mild steel tank. Another benefit of having no booster element is the elimination of tank degradation associated with hot spots caused by the elements. 

How long can I expect the unit to last?

During the manufacturing process great care is taken assembling the components with strict quality control measures. Many Quantum heat pumps in the field have lasted over 15 years.

Is a Quantum heat pump affected by hail or rain?

As a heat pump has no solar panels or collector tubes, and the components such as the compressor and evaporator are solidly encased by Zincalume steel, the unit is safe in all weather conditions.

What is the warranty period on Quantum heat pump units?

There is a five-year warranty on the water storage tank and the integral condenser, and a two-year warranty which covers refrigeration and electrical components.  An extended warranty for a further 2 years is available on commercial units.

Are replacement parts readily available throughout Australia?

Yes, all replacement parts are available in Australia.

How is a heat pump more efficient than electric or gas water heaters?

Normal water heaters use electricity or gas directly to heat the water and therefore their efficiency can never be greater than 100%, (and usually only 65%-98%). As a heat pump uses electricity only to run a fan and a compressor (and is not using electricity to directly heat the water) but transferring the abundant heat contained in the ambient air into the water tank, they have an efficiency rating well above 300%. This means 1 kW of electrical energy used by the heat pump can transfer 3.6 kW of heat energy into the water.
