Heat pump + Solar water heating = up to 91% efficiency

How a heat pump works:

A heat pump replaces the current geyser’s electrical
element thereby saving money.
Refrigerant gas is circulated in a continuous cycle. The liquefied refrigerant passes under pressure through an expansion valve in to a partial vacuum.  The sudden expansion of the high pressure liquid into a low pressure area (the evaporator) cools the gas down.  The refrigerant gas which is now at a comparatively low temperature is then suddenly pressurized by a compressor.

The sudden increase in pressure raises the temperature of the refrigerant gas considerably.  This heated gas is routes through a condenser and emits heat to the water that is to be heated in a storage tank near the actual heat pump.  It can also be emitted into the surrounding atmosphere in the case of a refrigerator or air conditioning system.

A. Passive system with tank above collector (Thermosiphon).

1. Direct Passive Systems – systems use water from the main household water supply to circulate between the collector and the storage tank. When the water in the collector becomes warm, convection causes it to rise and flow towards the water storage tank.
2. Indirect Passive System – passive systems use a non-toxic antifreeze heat transfer fluid (HTF) in the collector. When this fluid is heated, convection causes it to flow to the tank where a passive heat exchanger transfers the heat of the HCF to the water in the tank

The attraction of passive solar water heating systems lies in their simplicity. There are no mechanical or electrical parts that can break or that require regular supervision or maintenance.   The down side however is the Cylinder is visible on the roof or if in the roof, must be raised in order to be higher than the collector.

B. Active solar hot water systems employ a pump to circulate water or HTF between the collector and the storage tank. Like their passive counterparts, active solar water heating systems come as two types: direct active systems pump water directly to the collector and back to the storage tank, while indirect active systems pump transfer fluid (HTF), the heat of which is transferred to the water in the storage tank. Because the pump should only operate when the fluid in the collector is hotter than the water in the storage tank, a controller is required to turn the pump on and off.  The use of an electronically controlled pump has several advantages:

• The storage tank (Geyser) can be situated lower than the collectors.  A pumped system allows the storage tank (Geyser) to be located out of sight.
• Because of the fact that active systems allow freedom in the location of the geyser, the tank can be located where heat loss from the tank is reduced, e.g. inside the roof of a house. This increases the efficiency of the solar water heating system.
• New active solar water heating systems can make use of an existing geysers avoiding duplication of equipment.  
• Active systems can tolerate higher water temperatures than would be the case in an equivalent passive system. Consequently active systems are often more efficient than passive systems but are more complex, more expensive and more difficult to install.

So you’ve had a direct solar water heating system (pump driven ) installed.  How do you know that your system is working properly?  Without a digital management system, it is very difficlut to assess this.  I have seen direct system installations that are over 1 year old and thermosiphon’s during winter nights, effectively cooling down the heated water, therefore increasing power usage resulting in higher costs – quit the opposite affect the client was looking for! 

 A simple way around this is to install a Geyserwise controller.  With this unit you will be able to monitor temperatures both in the geyser and the solar collector/panel.  This will quickly tell you how effective your system is operating, both during the day and at night.

Here are some tips on how to save energy:

• Install a Geyserwise system to manage your geyser, reduce costs
• Buy energy-efficient light bulbs. Compact fluorescent light bulbs (CFLs) use 80% less electricity than ordinary light bulbs and last up to 8 times longer.
• Use low energy lamps and energy-efficient spotlights for exterior lighting.
• Buy energy-efficient appliances or gas appliances.
• Physically turn off appliance switches or at the wall (e.g. a TV or Hi-Fi), instead of leaving them on standby.
• Make one-pot meals and keep lids on pots.
• Bring foods to the boil quickly on the “high” setting, then turn the heat down to “simmer” to finish cooking.
• Keep the oven door completely closed until food is cooked (use the oven light to check food instead). Every time the door is opened, the oven temperature drops, and the heat must be replaced.
• Cold water short wash cycles and rinse-only cycles on dishwashers and washing machines are designed for energy and water conservation.
• Thick frost on chilling panels reduces a fridge and freezer’s cooling ability. If you do not have a frost-free model, defrost your fridge or freezer when frost is between 0.6 cm and 1.3 cm thick.
• Empty, switch off and clean your fridge before going on a long holiday.
• Defrost food in the fridge instead of the microwave oven as it is more economical.

There are so many different opinions about which solars are the best for our climate in Cape Town.  But now, with a geyserwise unit, you don’t have to guess whether they are working or worry that your system overheats and bursts, which by the way does happen.  Our experts are standing by to give you all the information on our range of energy saving products.
