Immersion Heater Elements for Wind Turbines


In our articles Wind Turbine Water Heating and 200W 12V Immersion Heater we looked at how a wind turbine generator can be connected directly to an immersion heater element in a water tank to heat water. Since cold windy weather occurs at times when hot water is required, such a system can heat water more efficiently and cheaply than a solar water heating system – and the wind can blow for 24 hours per day. Heating water also makes an excellent dump load for wind turbines connected to abattery bank to prevent overcharging during heavy winds.

Back in 2006 for example it was very difficult to find suitable immersion heater elements for use with wind turbines. However, one benefit of the recent jump in oil, electricity, and gas prices is that this market sector received a surge of interest and a wide range of different wattage and voltage immersion elements went on sale. Now in 2014, for some reason it is getting harder to find suitable immersion heater elements again!

500 Watt 12 Volt immersion heater element

Pictured above is an example 12V immersion element from a range of elements which we recommended for years. Unfortunately at the time of updating this article (January 2014) we cannot find these elements for sale anywhere. They were sold by emandco on eBay UK in the following four sizes:
(1) 1″ FI BSP
(2) 2 1/4″ MI BSP (standard immersion heater size)
(3) 3/4″ FI BSP
(4) 1/2″ FI BSP
Types 1, 2, and 3 were available with power ratings from 50 to 800 Watts, and Type 4 was available at up to 500 Watts. Black and red electrical connections were provided for easy connection to the 12V DC supply cables. Over the years, a 1200 Watt rated 48 Volt version, a 700 Watt 36 Volt version, and 24 Volt versions were added to the range.
These immersion heater elements were manufactured to order and despatched within just 4-5 working days from payment being received.
If we manage to find any more of these elements or find the vendor, we will add the details to this article.
