• What is a non-pressure solar water heater?

  A non-pressure solar water heater is classified as a “low” pressure when the water coming from the solar unit is gravity fed to your house. This means that whatever pressure you feed into the system it will still come out from the outlet and down to your house by gravity.

• Why do I choose a Non pressure solar water heater?

  When the cold water to your shower(s) is gravity fed from a tank on the roof or supplied by the CWA without usage of pump.

• How do I calculate the size of my solar water heater?

  Family of 2 -3 persons: 150L

  Family of 4 persons: 200L

  Family of 6 persons: 300L

• What is the average lifetime of a solar water heater?

  Your solar water heater will last 20 to 25 years

• How long will it take to recover my investment?

  Duraco Solar Water Heater can pay itself back in as little as 3 to 4 years. The system will last till 20 to 25 years, thus as from year 5 the client will continuously save money as opposed to gas or electric costs, which will rise constantly

• The Solar water heater is made of what materials?

  • The inner and outer tank of the system is made of Inox 316
  • The frame is made of aluminium alloy
  • The tube is made of glass

• What warranty is offered on the Solar Water Heater?

  • 8 years on the water tank
  • 15 years on the tubes and frame

  NB: No warranty if the system is damaged due to cyclonic conditions

• Can the SWH be installed on an inclined roof?

  Yes. In which case, a survey, free of charge must be done by a Duraco expert. However, an additional amount might be charged to the client depending on the modification to the metal support.

• What kind of maintenance is required for a Duraco Solar Water Heater?

  The system requires very little maintenance. The tubes need to be cleaned from time to time, especially in the regions where there is lots of dust.

• What is included in the price of the Solar Water Heater?

  The price includes, delivery, flat roof fixation and VAT; but excludes plumbing and electrical works.

• Can I buy a system from you and then install it myself?

• No. A self-installed system will not be covered by our warranty.

• What shall I do in case a tube breaks? Can I replace the broken tube myself?

  The broken tube will have to be replaced by our technical team. In case of water leaking out of the system from the broken tube, shut the inlet and outlet valves.

• What happens on cloudy/rainy day? Do I still get hot water?

  Our Solar Water heaters works with direct sun rays. On cloudy/rainy days you may lack hot water. However, our unit is equipped with an inbuilt electric booster which can be switched on when water is not sufficiently hot.

• If I shower in the evening, will I have hot water the next day?

  Hot water produced by the solar radiation during the day is stored in an insulated storage tank. As long as the hot water has not been completely used up, the insulated tank will keep the water hot without significant drop in temperature for up to 24 hrs. Thus water heated during the previous day should be available for use at night and next morning.

• Will my system be damaged if I go away on holiday?

  Nothing will happen to your solar unit as long as it is filled with water

• Are Solar water heater equipped with tubes collector more efficient than flat plate collector?

  Due to the cylindrical shape of the tubes, the collector is able to passively track the sun throughout the day, whereas the flat plate collector only provides peak energy output at midday when the sun is perpendicular to the collector’s surface. Moreover, evacuated tubes are strong and long lasting. Furthermore, should one tube get broken, it is inexpensive and easy to replace. If a flat plate collector panel is damaged the whole panel must be replaced.

• Can I heat my swimming pool using your solar water heater?

  No, our solar water heaters are only for domestic purposes
