The best way to save on electricity bills - Most people don't know about

Cost saving geyser. Uses heat from the environment to heat up your water.

Heat pumps save water heating costs

The biggest proportion of your monthly electricity bills go towards heating water and your stove.  In terms of total cost not much can be done to the running cost of your stove. Even if you switch to gas you are still paying a lot.  However, heating up water has alternatives.  Solar panels are not always the solution but they do help to reduce energy bills, the problem is if you have a lot of people in the house you might run out of hot water very quickly on a cloudy day.

Heat pumps use heat from the environment to heat up the water.  Just like solar panels use sunlight energy. The only electricity used is to pump the water through the system and run the fan for the heat exchanger. So there are no tanks or elements like those used in geysers.


How a heat pump can save you energy costs

How does a heat pump actually work

The fan of the heat pump circulates air through the outer evaporator that acts as a heat collector. The liquid refrigerant in the evaporator absorbs the available heat in the ambient air, transforming it into refrigerant. The refrigerant is then pumped into a compressor. When this warmed refrigerant is compressed, it intensifies or concentrates the heat, similar to a magnifying glass to the sun.

This intensely hot refrigerant is then pumped into a heat exchanger condenser where the actual heat transfer takes place.  As the water passes through the heat exchanger, the hot gas gives up its heat to the cooler water. The refrigerant returns to a liquid state and is pumped through an expansion valve and then into and evaporator air coil, which starts the process all over again.

Highest energy savings come from a heat pump

The reason why heat pumps are the most efficient systems to save on energy is because they utilize the solar heat stored in the environment. This free environmental energy provides approximately 75% of the heat pumps heating energy and only approximately 25% of external energy is required in the form off electricity in order to achieve a heat output of 100%

How to select a kitchen sink mixer

Image
Kitchen sink mixers are expensive items and should be selected based on practicality first and secondly aesthetics. Yes, off-course budget comes first but that is obvious.  So let’s see what is important in a kitchen sink mixer. Deck or wall mounted mixers This is a major consideration and one that must be decided on quite early on in the building phase. If you are going to decide on a wall mounted kitchen mixer than your plumber must chase into the wall and connect the fittings. If you are going to use a deck mounted mixer your plumber must install angle valves in the wall and the kitchen company must make sure there are holes in the granite top for the tap to fit in.  Also the type of kitchen sink will have an influence on your decision. Some kitchen sinks come with holes pre-drilled so then you don't have a choice. Most high end and designer mixers are deck mounted.  So if you want something fancy with bells and whistles design your kitchen around a deck mounted one.

Is there quality differences in stainless steel kitchen sinks

Image
Upmarket high quality kitchen sinks are always made from grade 304 stainless steel and are at least 1 mm thick. One of the upmarket Teka sinks sold at Chilli-B (www.chilli-b.co.za) So many people have asked me what is the quality difference between various kitchen sinks. It is a very difficult question to answer because there are so many factors that one should consider. Obviously the first thing comes to mind is your budget.  So the question is more, what is the best quality sink I can buy within my budget.  That changes the problem slightly and I can break it down to a couple of important features what to look for. Price In general the higher the price the better the quality. We all know that but if you are worried then go with the higher price but also look at the warranty period and what is covered.  The sink with better warranty specs is a lower risk to the supplier or manufacturer so he is prepared to give a longer warranty. One other thing on price, be careful to compar

FAQ on glass splashbacks

FAQ on glass splashbacks What is the biggest size glass that I can choose? Maximum workable splashback panel size – ±3100 x 1200 mm, bigger sizes will be butt joined. The maximum size is actually determined by the oven size. Large ovens are found in Johannesburg and Cape Town. What exactly is glass splashbacks? In simple terms it is toughened glass which is back painted (backpainted) with automotive paint. Permanent adhesion is obtained by mixing the urethane paint with a catalyst which changes the molecular structure of the glass, which ensures the permanent bonding between glass and paint.  So the paint used is not a PVA or water based paint. What are the main advantages of glass? The strong adhesion between paint and glass makes the product durable. Glass is easy to clean & maintain since it is non porous and any chemical can be used to clean it. Toughened glass is safe. If it breaks it shatters into small pieces that will not cause serious injury like stan
