If you live in an area that hits temperatures approaching zero degrees you need the right solar hot water system. To show you how frost can affect your system, let me first explain how it works. Standard solar hot water panels contain copper pipe (risers) filled with water. This water circulates around the panels where…
Heat pump water heaters are relatively complex compared to other water heaters. This means that there is a variety of designs, energy efficiency and performance in available heat pump water heaters.
Heat pump water heaters operate using a refrigeration cycle that moves heat from a high temperature source (the outside air) to a low temperature destination (the hot water in the tank). In nature heat flow tends to go from higher to lower temperatures. Heat pumps mimic this natural flow by using a refrigerant that boils…
The Small-Scale Technology Certificate (STC) price from Green Energy has today risen to $37. This is the highest level since around June 2010.
Under the Small-scale Renewable Energy Scheme, eligible hot water and power generation systems are entitled to a number of Small-scale Technology Certificates (STCs) usually as a deduction from the point of sale price. Solar and Heat Pump Hot Water Systems Approved solar hot water and heat pump hot water systems are eligible for STCs. STCs…
The Clean Energy Council has produced a fact sheet to help buying solar hot water and heat pump hot water systems. The fact sheet provides: an overview of solar hot water systems and heat pumps explains how they work and provides a checklist to ask your supplier and installer to help you ensure you get…
