Hot water systems
The most environmental solar hot water system:
Circulates water by natural convection ('thermosiphon') instead of using an electric pump. This requires no electricity and so is very eco-friendly. However your water tank needs to be placed on the roof.
A solar hot water heater requires control:
Of the pump and booster heating. If not used effectively, you won't see the full energy savings. Right House will show you how to use the controller properly to ensure you get the maximum benefit.

When considering a hot water system for your home you need to consider a system that will not only provide sufficient hot water when you need it but also produces it energy efficiently. There are a large number of hot water systems available including:
- convection electric or gas storage
- instant electric
- solar hot water heaters
- heat pump hot water heaters; or
- wet backs.
Other hot water systems are also available, however these are usually more specialised systems, or only apply in a small number of specific locations. If you wish to discuss any of these systems then please contact a Right House consultant.
When selecting the appropriate type and model of hot water heate for your home you should consider:
- Energy source: The type of fuel or energy source affects its ongoing operating costs, size, and energy efficiency
- Size: The correct sizing of your hot water heater is essential (whether energy efficient or otherwise). A household usually uses 214 litres of water per person per day, of which about 40 % is hot water.
- Energy efficiency: There are a variety of energy efficient hot water systems available on the market. It is important to ensure that you consider which system is most appropriate for your home and your lifestyle.
- Capital cost: The operational savings from an energy efficient hot water system have to be considered in relation to the capital cost of a system.
Right House supply and install four kinds of energy-efficient water heating systems:
- Solar water heating: Depending on where you live, a flat panel or evacuated tube solar system can supply up to 50-75% of your hot water requirements. You will usually see greater energy savings in summer than in winter, because that’s when the most sun is available.
