Q: How does a evacuated tube solar hot water system work?
A:
The operation of the solar collector is very simple
|
The sunlight strikes the dark-blue absorber inside the evacuated tube.
2. The copper heat pipe within the tube transfers the heat up to the copper header pipe
housed inside the in sulated manifold box.
3. A pump circulates water from the storage tank through the copper header pipe warming
the water.
4. The solar heated water is then returned to the storage tank raising the temperature.
5. Gradually the water in the storage tank is heated.
6. The water is boosted by electricity or gas as required to ensure hot water even during poor weather.

Q Q: Does my roof have to face North?
A: If your roof space is not northerly but within 45° of north you will only suffer a few percentage loss of solar gain. If you have a flat roof then mounting frames can be provided to obtain the correct panel inclination.
Q: What if I live in a frost prone area?
A:
If you live in an area prone to frost or clear cold nights, its possible that water can freeze and damage the panels. Manufacturers do make Anti-Frost panels which are used and are designed to keep a small amount of fluid and warm water to circulate to stop the water freezing on cold nights.
Will I run out of hot water?
A:
All our solar hot water systems are fitted with a gas or electric booster as a ‘back up’ to ensure your water is always heated to the correct temperature - even when the sun isn’t shining.
Our solar hot water systems are fitted with solar collectors designed for maximum heat absorption, so you’ll have hot water on tap, all year round.
Q: Can water be heated on a cloudy day?
A:
Yes. Although the heat output of the solar collector is reduced on overcast days it will still be able to provide heating. If it is a heavily clouded day or raining, then more gas or electric boosting may be required to maintain water at the required temperature.
Q: Is solar water heating a viable alternative to gas or electricity?
A:
Solar should not be seen as a alternative to gas or electricity, but rather a supplement. Solar cannot totally replace the need for gas or electric heating as there are sometimes days when there is little sunlight. When averaged over a year, a correctly sized solar system can provide 60%-90% of a household's hot water needs.
Why is solar hot water good for our environment?
A:
With solar hot water you’ll not only save money, but you’ll help our environment too. According to the Australian Government, water heating is one of the largest single source of greenhouse gas emissions from the average Australian home, accounting for around 28% of home energy use.
It also reduces your energy bills by using the sun’s energy to heat your water.
In fact, solar hot water systems are so good for our environment that Renewable Energy Certificates and government rebates exist to make it easier and more affordable for you to install solar hot water.
Heat Pump Hot Water FAQ's
Q: Will the system work during bad weather?
Q: Why is a Heat Pump more efficient than electric or gas water heating?
Q: Do Quantum Heaters require a booster?
Q: What is the warranty on the Quantum unit?
Q: Will I run out of hot water?
Q: Will the system work during bad weather?
A:
Yes Quantum has been designed to work all year round without boosting. Rain wind and sun are major elements in making the unit run effectively.
Q: Why is a Heat Pump more efficient than electric or gas water heating?
A:
Normal heating methods use energy such as electricity or gas to directly heat the water. This can never be greater than 100% (but more likely 60% - 75%)
efficient
. A heat pump only uses electrical energy to run the compressor, not to heat the water. The heat energy actually comes from the atmosphere.
Q: Do Quantum Heaters require a booster?
A:
No! Quantum has the ability to deliver 600 to 1,300 litres of hot water per day without boosting. With the evaporation temperature of the refrigerant being well below 0
°
C it will vaporize in all weather conditions. By compressing that vapour Quantum will generate heat equivalent to a 3.6 kW booster during its heating cycle.
Q: What is the warranty on the Quantum unit?
A:
There is a 5-year warranty on the water storage tank. 2 years on Refrigeration and electrical circuits.
Q: Will I run out of hot water?
A:
Quantum has the ability to deliver voluminous amounts of hot water. However it must be remembered that it is a storage system, and, if drained of hot water in a short period, it will need approximately 3 to 4 hours to recover.
Q: We use most of our hot water in the evening; will the unit recover by the morning?
A:
Yes! Even on the coldest winter night, Quantum will recover for early morning use.
