HEAT PUMPS

CAUTION

It is imperative that you always make sure that your contractor is qualified to install heat pumps and that he provides proof thereof. He must in addition, have the sufficient training in the products to be installed or a poor or inefficient system is bound to be installed. All safety compliance regulations must be adhered to at all times when dealing with hot water pressure systems !

Heat pump technology is one of the cutting edge technologies when it comes to renewable energy water heating products. Even though this technology have been used in South Africa for heating water for many decades the recent increase in international demand have brought the component costs down making the product extremely affordable for the residential and commercial users.

Using refrigeration cycle to extract energy from the surrounding air (indirectly using solar energy) it can provide you with 60°C hot water day or night, winter or summer at a quarter of the cost of electrical geyser element heating.

Drainmen Services are known to be a leader in the design and installation of heat pump heating technology and only procure some of the most efficient systems on the market. Heat pump range:

How does a Heat Pump work?

A heat pump works like an air conditioning unit in reverse. It extracts heat from the ambient air surrounding it, enabling it to heat the refrigerant which is then compressed causing it to get even hotter. This is then run through a heat “exchanger” in which the water is heated. The refrigerant is then allowed to expand again, thus cooling it down and enabling it to again absorb heat from the surrounding air. So only a little electricity is used to run a fan and compressor while the heat energy is provided indirectly by the sun.

The modern domestic heat pump is a very efficient water heating device which uses a small amount of electricity to drive a compressor which forms the heart of the heat pump. The heat energy produced is as much as four times the electrical energy used to drive the compressor. This means that your electricity consumption for water heating can be divided by up to four.

The heat pump is not reliant on sunshine or direct radiation but extracts heat energy from the air at any time of the day or night and so is effectively a solar heater in a different form. Even in extremely cold conditions (-5C and lower) the heat pump can still provide a saving of more than 50%. In most cases in South Africa, where our daytime temperatures are relatively high, the efficiency is going to be at least 3 x that of an element heated water system. Even in the colder climates of Europe heat pumps are extensively used in domestic applications.

A heat pump looks similar to an air conditioner and can be installed either on the ground or on brackets on a wall. It is quiet and unobtrusive with a user friendly controller, has no greenhouse gas emissions and requires almost no maintenance.

Heating systems for your pool / Jacuzzi’s :

Drainmen Services also install pool heating heat pumps and these are designed to make you get the most enjoyment from your pool and/or Jacuzzi.

It will provide you with many years of trouble free pool heating.

Drainmen Services keep updated with constant evolving technology so you can be sure that your heat pump uses the latest in heat pump control technology resulting in extremely low operational cost. For every R1.00 worth of electricity our unit will give you more than R5.00 worth of output heat!

Drainmen Services heat pump systems boast a 500% efficiency rating which means you will gain a return on investment in less than 1 year.

Why should you heat your pool?

Not only did you pay a lot of money to build your pool but it is also costing you a lot of money per month to maintain. The average pool owner in South Africa only uses his pool for 3 months of the year because the water is simply too cold the rest of the time. By using an approved Drainmen Services heat pump, you can now enjoy your pool all year round thus getting the most from your swimming pool investment. You and your family will experience hours of fun in the pool instead of around the pool.
