Frequently Asked Questions

Q1. Why do we always seem to run out of hot water?

A1. There could be several reasons why, from the number of people living at the property, the length of time people stand in the shower, whether it is summer or winter, do you have water efficient flow restricters on the outlet of the hot taps to limit the hot water used, maybe you are on the wrong electricity tariff, or your hot water system is just to small and you may need a larger hot water tank.

Q2. Our electricity bill always seems expensive?

A2. Electricity bills are always expensive but, check the amount you are charged for the hot water portion only on the bill, a lot of people look at the total cost for all the electricity used & just not the hot water part, you may not be on the best tariff for your requirements, contact us & we can advise you appropriately, a night rate tariff is the cheapest for an electric hot water system & a heat pump system can save you approximately 67percent compared to an electric system. 

Q3. We want to buy a solar heat pump new hot water unit but are unsure how to claim the government rebates?

A3. Don't worry, when we supply & install the new hot water system for you, we will supply you with all the relevant rebate paperwork already filled out for you to send to the relevant government department to claim all the rebates available to you. You wont have to go searching for all the forms, we will look after you.

Q4. Can I replace my leaking electric storage water heater with another electric hot water system?

A4. The criteria outlined by the Queensland Government for being able to replace your existing leaking electric hot water system with another electric is:-
If there is a natural gas pipeline running past your boundary & the gas supplier will bring the gas meter to your boundary for no cost to you, then you will not be allowed to install an electric system, you will have to install either a gas, solar or heat pump system, if the gas company intends to charge you, then you can refit an electric.  

Q5. Can we save money if we install a Solar or Heat Pump hot water system?

A5. Solar or Heat Pump hot water systems can save you money on your running costs by cutting your energy use. They will reduce greenhouse emissions by up to 65% in most parts of Australia. Your financial savings will vary depending on the type of Solar hot water system you install meaning if the direction and angle of the solar collectors on the roof are correct, how much hot water you use and your electricity tariff. Talk to Flo-Rite Plumbing for more information on an energy efficient system.

Q6. How often should I have my hot water system serviced?

A6. Each hot water heater or system model has different servicing needs, they will also vary by how they are used and factors like water quality play a large part on the wear and tear of things like the heating element and pressure temperature relief valves. Talk to us or see your Owner's Guide for more information on the model of hot water system you currently have installed. at your premises.

Q7. What's the best Gas water heater for us to install at our house?

A7. The best depends on what's right for you, there are two types of hot water systems:- Continuous Flow water heaters, which heat the water as you use it but generally provide the water flow or pressure at the taps at a lower rate  than storage systems, but deliver hot water continuously & Gas Storage water heaters which use a storage tank to store the heated water ready for use, then supply it at mains pressure, the advantage of the storage system is you can run several taps or showers at once.

Q8. What's the most cost effective water heater or hot water system to run?

A8. To figure out what's the cheapest water heater to run, there's a few things you need to think about, like: Is natural gas available to your home? If it is then gas boosted solar, or 5 Star gas storage or continuous flow may be the best for your needs. If natural gas is not available then an electric boosted solar or heat pump hot water system might be the answer. Electric water heating on off peak tariff can have the lowest running cost, providing you are on the correct tariff, ask us for help.

Q9. Why does my storage hot water system leak out of the overflow?

A9. Depending on the brand of your hot water system, it may be normal for your system to leak water on the heating cycle. This is caused due to expansion, when the cold water in the tank is heated by the element or gas burner therefore water expands & some water will escape from the pressure & temperature relief valve so damage is not caused to the storage tank, this water should stop to leak once the unit has heated to the correct temperature & the heating element or gas burner has turned off.

Q10. We have just had a new hot water unit installed and the water is not as hot as our old one?

A10. Tempering valves are know required by law in Queensland in all new homes, renovations or when replacing an old hot water system. It is law to have a tempering valve installed to control the water temperature to all bathing fixtures in your property. Your hot water installer has probably installed a tempering valve when they installed your new hot water system, this valve mixes hot & cold water & delivers water no hotter than 50 degrees.

Q11. How does a heat pump hot water system work?

A11. A Heat Pump Hot Water System operates like a refrigerator in reverse. It contains a fan that forces air through an evaporator that contains a refrigerant. The heat in the air passes through the evaporator and is absorbed by a natural refrigerant, CO2 (R744), which is ozone friendly and does not contribute to global warming. The warm gaseous refrigerant is circulated in the system via a compressor. As it passes through the compressor, its pressure rises, as does its temperature. This hot refrigerant then passes through a heat exchanger to heat the water, which is finally pumped to the storage tank. Then the process starts all over again.

Q12. If I go away on holidays from my house, can I turn my hot water heat pump off at the electricity box?

A12. Yes you can. Turning the power off will not affect the unit. Just switch the power back on when you get back.
