BASIC SYSTEM SIZING

1-2 Bedroom Home

This size home is what we classify a "Small" home.  In most regions, a 22 Tube 250 Litre system is sufficient for this sized home.

However in the colder regions of Australia - some consumers opt for a 30 Tube 250 Litre system to give them maximum output.

3-4 Bedroom Home

The standard Aussie home is the 3-4 bedroom and what we classify as a "Medium" home. The ideal unit for this size is a generally a 30 Tube, 315 Litre system.

The Apricus 30 Tube, 315 Litre system will handle a family of 4-5 due to the extra storage.

5+ Bedroom Home

5+ Bedrooms are classified as "Large" homes, and generally a 44 Tube, 400 Litre system is required for this size home.

As a 30 Tube is the largest single manifold that Apricus manufacture, when going to this size 2 x 22 Tube manifolds are used and connected together.

PITCHING FRAME REQUIREMENTS

Is a Pitching Frame Required?

Due to the technology behind the Apricus evacuated tubes, the angle of installation is very important to optimise the performance.

As a rule of thumb, any roof under 20° pitch requires a pitching frame.

The ideal angle for Winter performance is 45° or  approximately +10° of the installation locations latitude. This maximises the performance in Winter.

Popular Regions Latitudes:
  • Cairns 17° - Ideal for Winter = 27°
  • Brisbane 27° - Ideal for Winter = 37°
  • Sydney 33° - Ideal for Winter = 43°
  • Melbourne 38° - Ideal for Winter = 48°
  • Perth 32° - Ideal for Winter 42°

CHOOSING A BOOSTER

Electric or Gas Booster?

Selecting the correct booster is just as important for a solar hot water system as the sizing of the collector and storage tank. Inefficient boosting can result in wasted energy and higher running costs for the consumer.
Electric Boosting:

If electric boosting is best suited for the household, there are a few configurations that can be used.
  1. Off-Peak boosting - The main benefit of off peak is the lower cost, however if the household showers at night they will drain the tank, off peak will heat overnight and in the morning when the sun comes out no heat is required.

  2. Electric Timer - Set for 4-6pm daily allows the solar to heat as much as possible and any extra heating is done by electricity prior to evening showers. (Remember the booster will only turn on if water is below 65°C, and will switch off as soon as 65°C is reached).
Gas Boosting

The biggest benefit of gas boosting is the household will receive virtually unlimited supply of hot water, as gas boosting is done by an instantaneous gas heater.

The Apricus gas boosters are generally a good choice if the home has natural gas or LPG gas connected for cooking and other appliances.

Gas boosters will start only when heating is required, however it is worth explaining to the consumer that if the water in the pipes between the tank and booster goes cold, it may start up for a short period and then switch back off.
