Did you know?
One of our domestic solar thermal systems can operate at a staggering 150 degree C during normal operation on an optimal bright sunny day. This is perfectly normal and safe but gives you some idea of how much natural energy is around us and how little we use it. The big challenge facing us now is how we harness this abundant energy safely and without stripping our planets resources.
An old and trusted friend.
We've all probably seen the old tanks plonked down on top of a flat roof somewhere in the Mediterranean, with a black pipe running down to a shower? Well that's solar thermal in its more primitive albeit charming form. Things have moved on slightly since those days and we at Luminii can help you design the very best available to suit your needs.
Solar Thermal converts the suns energy into hot water. We have been installing this technology for many years and can offer anything from a standard domestic system designed to heat your homes hot water right up to industrial process water for catering or cosmetic industries.
Our solar thermal systems are guaranteed for a 20 yr product lifespan so you can be sure that these robust systems will be chugging along nicely for many years to come generating plenty of free hot water.
We can supply either flat plate collectors or vacuum tube ones. They have fairly similar characteristics but vary slightly in terms of performance. The vacuum tube option is considered the turbo version. They employ a selective coating inside the borosilicate glass tube to make sure all the suns energy is harvested and converted into hot water. The vacuum then ensures that only an incredibly tiny amount is lost as the heat is transferred to your domestic hot water cylinder or other holding vessel.
A typical domestic system can deliver between 55 - 60% of a home's hot water requirements. If you calculate your average gas or electric spend on this and deduct 55 - 60% you will have a figure but as a rule of thumb this usually equates to around £350 pa. And this system is going to go on producing that hot water for 20yrs plus...
