Solar panel heating water to 80C in under 10 minutes

Solar panels heat solar hot water to 80C within minutes of plumbing a Solartwin freeze tolerant solar panel into a bucket (on a windy spring day in England). Part of a Solartwin.com solar energy installer "how it works" training active seminar aiming to take the fear out of how to fit solar panels to deliver solar heat power and save energy in an affordable way. How does solar work? Here's the simple reliable way! The best solar heating is what we aim to make.

Thanks for the comments. I've just uploaded a new video entitled "solar heating cowboys" which develops the point abouth the solar electric pump. This can boost environmental performance of solar water heating systems by 20% in terms of carbon savings. There is also more on the solartwin site. Regards, Solaryes Barry.

Whats the website to buy one,?

[solaryes]

Thanks for asking what is the website. It is available from Solar Twin Ltd's site.

The fresh hook-up allows quicker result is achieved using pre-heated pipes. Is it a drain-back system that comes on when temps are high enough to produce? (I found his accent hard to follow...maybe he addressed it? Will see the web site later, perhaps)

[solaryes]

It is not a drain back, it is permanently filled with water.

Thanks for this analysis. Most solar users want to heat their water over a day, rather than a few minutes - and what is offered generally meets this requirement. Faster heating would mean larger panels and therefore greater cost.

@urbex2007 Unless you shower every 10 minutes and use your clothes washer at the same time who cares if it takes 6 hours. Also consider that most of these solar water heaters are designed to prime your existing hot water tank with already near temperature water. so instead of your hot water tank using 15-30 mins to heat up, it takes 5 minutes instead. That can mean a saving of electricity equivelent to 60-80+%

@solaryes Looks like a good system! I am really intereasted in the small solar pallen and the pump! That is a very good way to pump water! You could make a drain back system with this if you needed to! Any help from Mother Nature is welcome!

It can help with a preheat tank though, instead of cold ground water topping up your geyser when you use it, thus not having to have your element keep coming on.

I don't get it "never be efficient enough" for what exactly?

Water retains A LOT of heat, a sufficient large watertank would provide more than enough warm water for house heating and warm water.
