How Does A Domestic Heat Pump Work?2021-03-26T11:12:48+02:00

A heat pump works like an air conditioner in reverse. It uses a relatively small amount of electricity to extract heat from the surrounding air and then heats water with this energy. Click here for more information

How Much Money Will A Heat Pump Save Me?2024-04-22T10:47:24+02:00

A domestic heat pump with a real life COP of 3 (efficiency of 300%) will save you 66% of the electricity currently used with a normal electrical element. So, for example, a family of 4 with a 200L geyser is currently using R1260/month to heat the water. If a heat pump with a COP of 3 is connected to this geyser and the current electrical element is disconnected then they will not only use R420/month to heat the water. This equates into a saving of more than R62 000 over the next 5 years.

How Long Does A Heat Pump Take to Heat Water?2021-03-26T11:11:55+02:00

An ITS 4.7kW heat pump will heat the water slightly faster than a 4kW electrical element typically found in 200L geysers. The ITS 4.7kW heat pump produces 4.7kW of thermal energy under specified conditions while using as little as 1.2kW to do so.

What is the Average Payback for A Heat Pump System?2021-03-26T11:11:45+02:00

Heat pump systems can save the home owner or business a substantial amount of money and drastically reduce global warming. At current energy prices, these systems can pay for themselves in 1-4 years, depending on the application and water usage.

How Long Will it Take to Install A Heat Pump?2021-03-26T11:11:30+02:00

On average it takes half a day to install a heat pump system.

How Hot Can A Heat Pump System Make The Water?2021-03-26T10:58:23+02:00

ITS heat pumps are designed for a maximum temperature of 60°C. The heat pump can produce these temperatures even with the ambient temperature being below 0°C.

How Much Maintenance and Service is Required?2021-03-26T11:11:11+02:00

In order for the domestic / commercial heat pump warranty to remain valid, ITS heat pumps need to be serviced once a year by an accredited ITS service agents. A service entails a general system clean off, de-scaling of the evaporator & an evaluation of the parameters. Just like your car, an annual service will ensure that the unit continues to work optimally for years to come and continue to offer you the best possible saving. Call us to find out more.

Can I Use A Heat Pump Water Heating System with My Existing Hot Water System?2021-03-26T11:10:58+02:00

Yes. ITS manufactures a special loading valve to change your normal geyser into a heat pump geyser.

What is the Life Expectancy of A Heat Pump System?2021-03-26T11:10:08+02:00

The life expectancy of a heat pump is around 10 years.

What are the Advantages of Heat Pumps Over Solar Collectors?2021-03-26T11:10:33+02:00
  1. A solar system is designed to heat the geyser once per day. A heat pump can re-heat a geyser a few times per day and so it is not a problem if your need more water than usual.
  2. A solar system only works when the sun is shining. A heat pump can work day and night, rain or shine.
  3. To get the most from your solar system, you have to usually change your water heating usage pattern a bit while with a heat pump it makes no difference when and how much water you use.
  4. Heat pumps provide a guaranteed peak demand reduction on your electricity supply. If you for example had a 4kW element and replace it with a 4.7kW heat pump you have now only got a 1.2kW load. With solar water heaters the backup element required will typically still be a 3kW or 4kW load.
  5. In most cases a heat pump will provide a better saving than as solar heating system for a client using 150L or more of hot water per day. Solar can provide a better saving but this requires the system to have adequate storage (usual double the geyser size), usage pattern adjustments by the client and it must be installed in an area like Gauteng that has very constant daily sun throughout the year.
