A tempering valve is used on domestic hot water systems to mix the hot and cold water so the water coming into your home is not above 50oC. A tempering valve is installed in new homes. It is also required on many homes built before 2000 where a solar hot water system is replaced or…
Electrolysis occurs in all enamel coated steel storage tanks. Electrolysis causes tanks to corrode. To slow down the corrosion, a sacrificial anode is attached within the tank. The anode attracts the electrolytes more than the tank walls, which means the sacrificial anode corrodes rather than the tank. Depending on the quality of the sacrificial anode…
To answer the repair or replace question, several important factors need to be addressed including: Age of the air conditioner Has the unit been well maintained? Cost of the repairs Risk of more repairs being required soon? Availability of replacement parts Availability and cost of refrigerant Is the existing refrigerant pipe work suitable for the…
Most of the battle in minimsing ducted reverse cycle air conditioning running costs is choosing the right system in the first place. There are a couple of things you can do with your existing system – check out steps 3 and 4. 1. Check Out The Efficiency Energy Efficiency Rating (EER) and Coefficient of Performance…
No. We believe gold ducting is a gimmick. The critical thing to determine the performance of ducting is the thermal rating of its insulation. We use R1.0 thermal rated insulted ducting. BCA require a minimum of R0.6 in Perth WA . The industry norm is R0.6.
Sunlight is converted to DC (direct current) electricity using the silicon and other chemical elements within the solar panels (PV array). The DC current runs down the electrical cabling to the inverter. The inverter transfers the current from DC to 240 volt AC (alternating current)- so that it is suitable for use in your home.…
How do you service an evaporative air conditioner? It is straight forward, as long as you are happy getting on to your roof. Remove filters & wash with a hose, If you have an old system, pull out the sump dump to release the water from the tank, If you have a new system there…
In Perth, WA the ideal position for solar hot water system panels or solar power panels is facing true north on a 30 degree pitch.
There are arguments for and against hanging ducting. We don’t hang ducting because over the life of your ducted air conditioning system there will be stress on the point where the ducting is hung. We believe this is more of a risk than the ducting getting damaged because it is lying on the ceiling joists.…
Multiple split system (or multi-head) air conditioners comprise several wall split air conditioners powered by one outdoor unit. Advantages of Multiple Split System Air Conditioning Flexibility – Individual room temperature and air flow control (as you have a split in each room). Running costs – Potentially lower running costs than many ducted reverse cycle air conditioners if…
