10 Evacuated Tubes, Solar Collector of Solar Hot Water Heater, Vacuum Tubes, new

Having the big brother of these dinky tubes ( 60 of them) on our roof heating all our hot water right through the year, I bought these tubes as novelty gifts which can be used to boil water while you wait on the patio in summer time. At a tenner a time this has brought a lot of fun to the recipients

Pretty good for the price.The unit is quite small and struggles to give you a tank full of hot water but after 6 hours inthe sun it has done most of the work and just 5 minutes of immersion heater finishes it off !Or of course you can just have a very warm shower ....Assembly Instructions could be better ?thanks ...
