Efficiencies of Heat Pump Hot Water Cylinders
Heat pump hot water cylinders are one of the most efficient producers of domestic hot water. The benefits to the environment are reduced energy consumption with zero emissions and for… Read more
Low Pressure Cylinders, Water Quality and Green Haired Blondes
Throughout New Zealand reticulated water for public use has to meet strict quality levels with guidelines set by the Ministry of Health. Private water supplies may not meet such standards… Read more
Continuous Energy Savings with Water Heaters
The high efficiency principle of utilising heat recovery and transfer from condensed flue gases is now available in the continuous flow range of water heaters. The technology uses two heat… Read more
Gas Continuous Flow Explained
Gas continuous flow water heaters operate with an on demand principle; you open a hot tap and cold water flows into the unit which rotates a flow turbine, this sends… Read more
Natural Efficiency
Gas water storage cylinders are often overlooked when looking for a highly efficient means of water heating; the Rheem Stellar reaches 90% efficiency using a `twin pass` heat exchange principle… Read more
Hydronic Heating
Hydronic heating systems circulate hot water as a transfer medium to heat exchangers such as radiators, convector heaters, calorifier coils and under floor heating pipes, the heating methods being conduction… Read more
