Hot Water Cylinder Options

South Island Plumbing provide extensive hot water cylinder options from electric & gas to heat pump hot water solutions including whole home heating solutions incorporating hot water.

Heat Pump Hot Water Cylinders

On average, over half of a home’s energy consumption is taken up by traditional hot water & heating, so when considering how to reduce energy costs & improve heating efficiency, it makes sense to turn to hot water heat pump technology.

Heat pump technology that revolutionised home heating in New Zealand can be just as effective and efficient at heating your home’s hot water.

Heat pump hot water cylinders use electricity far more efficiently than ordinary electric water heaters. By extracting heat from the ambient air, hot water heat pumps have a low cost of operation compared to gas or electric elements & with their supreme energy efficiency they are one of the most environmentally friendly sources of heating available.

“Consumer NZ research shows that a well specified and installed heat-pump water heater would reduce your hot water bill by two-thirds over standard electric water heating.” https://www.smarterhomes.org.nz/

Heat pump hot water cylinders can also connect to whole home heating solutions such as the Daikin Alterma system or the Mitsubishi Electric EcoDan creating the most cost-effective whole home package.

Daikin Altherma

Daikin Altherma Hydronic Heating Systems are highly flexible, energy efficient home heating systems. At the heart of the system lies an innovative air to water heat pump that provides hydronic heating and cooling all year round. Unlike traditional hot water heaters, the hot water does not stay in the storage tank, it is heated instantly as it passes through the tank. 

Daikin Altherma

There are several different options available to provide heating in your home and Altherma is compatible with all of them. The selected system can simply be connected to the Altherma unit. The below can be connected to your system:

  • Underfloor heating: possibly the best solution for new installations, maximum comfort and efficiency due to radiated heat and is unobtrusive.
  • Fan coils: able to heat and cool, cased or concealed units, individual control & easy installation
  • Radiators: traditional heating solution, low capital cost & easy installation

Mitsubishi Electric EcoDan

With proven Mitsubishi Electric Technology, Ecodan is designed for New Zealand conditions; maintaining high performance during the winter months when heating is in high demand.

Chlorinated Water & Water Cylinders

Chlorinated water not only leaves a nasty taste in your mouth, but it is also corrosive on copper, brass, copper, galvanized iron, stainless steel pipes & fittings making them prone to leak. It can even wear away the protective alloy coating on heating elements causing them to fail.

“Chlorine is likely to be to blame for the failure of some hot water cylinders in Christchurch, according to a report issued by a University of Canterbury scientist. The analysis was performed by Professor Milo Kral on four hot water cylinders, from three different brands, that had suffered corrosion ‘pitting’.” For more information, click here to read Newshub’s report on hot water cylinder failures in Christchurch.

If you live in an area that has chlorinated water, such as Christchurch, it is advisable to check regularly for any signs of damage before leaks occur. Signs of possible corrosion include white build up (calcification) around fittings or blue-green stains in baths or sinks.

Left unresolved corrosion can lead to major leaks, structural damage & possibly even health issues caused by damaged pipes & fittings contaminating your drinking water.
