A solar hot water system will heat your water during the day for free! That can mean a massive decrease of your energy bills, as up to 90% of your families water usage can be provided via a solar hot water system.

Unlike many other appliances and purchases made – a solar hot water system will payback its initial cost over the years due to reduced energy bills, and although you are outlaying a larger amount of money compared with other hot water systems – in Perth the benefits will far outweigh the initial costs. Using renewable energy a solar also greatly reduces the greenhouse gases your household produces. All of this means solar will be a solid investment for every household to make.

As with any other major purchase you make – it is important to make the right decision when choosing a solar to install – that’s where we come in, as a company of tradesmen (not salesmen!) every person at One Earth Outlet is experienced within the industry to help you with the right option to suit your household.

Close coupled on roof solar systems

The most commonly installed solar hot water system in Perth is what is called a passive system (or close coupled) where the tank and panels are both situated on the roof. This system works via a thermo-syphoning effect where cold water travels down to the panels, is heated by the sun and then rises to the tank. This all happens without the need for any pumps or mechanicals, because of these reasons the close coupled system is the most cost effective and has the lowest maintenance. The main systems we install are;

  • Envirosun 300L TS System
  • Rinnai Sunmaster 330L System

Split solar hot water systems

Active systems (or split systems) is where the tank is installed at ground level. This means in order to get the water up to the panels and back down again a circulator pump (a small electric pump) is utilized. This system generally is more expensive to install and has higher maintenance costs. Although one major advantage – especially for new houses – is that it has a lower impact on the roof, and is more visually pleasing to most homeowners, especially where the north facing roof is the front of the house. A few systems that we install are;

  • Rinnai Sunmaster 315L split system
  • Envirosun AS 400L Split system

Heat Pumps

Another option can be a heat pump – these systems are recommended where it is either undesirable to have panels on the roof, or where space is an issue. Generally heat pumps work like a fridge (but the opposite!) they gather humidity from the air and turn it into hot water. Heat pumps work on electricity – and are boosted by electricity – so it may also be an option if you don’t have reticulated gas. They work better in humid climates – so in Perth they have potential, but can be a better choice when installing further north in WA. As this system is the most mechanical and complicated of all the systems, it has the highest maintenance and running costs. The systems we install are;

  • Rinnai Heat pump
  • Dux 250L Heat Pump
  • Rheem 310 Heat pump\
  • Midea 280L Heat Pump

Gas or electric boosting?

The traditional way of boosting a solar hot water, when the sun doesn’t do the full job - is an electric element within the tank. This element is submerged in the tank and by turning on the electric switch it simply heats up the water to the temperature set by the thermostat next to the element. This can be manually operated via a switch in the meterbox or a timer where it can be set to run at certain times of the day in-line with the families usage or to take advantage of power tariffs eg smart power. Another option – becoming more popular these days is an instantaneous (inline) gas booster. One major advantage to this gas boosted system is that the gas booster does all the work for you – it decides via the gas unit when you turn the tap on to what extent the gas flames fire up and therefore inline gas boosters guarantee that you always have hot water when you turn on a tap. This instantaneous boosting also means you are maximising the free hot water from the sun – as you aren’t boosting up the water in the tank unneccesarily. Our gas boosters can be added to any system, the recommended inline boosters we use are;
