Solar Thermal
I have heard today that our solar panels have just been fully registered for the feed in tariff - and since the installation in July the sun has shone and I have learned how to re-plan the day for the maximum use of our own generated electricity. I am delighted with both the installation and the outcome.

Q: Can I claim a grant for this technology?
A: Yes, The RHI or Renewable Heat Incentive is a government incentive available to people investing in low carbon technologies. Please visit The Energy Saving Trusts or The Department of Energy and Climate Change (DECC) to find out more about this scheme. 

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. 

Solar Thermal

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.

Case Study

We were invited to design and install this system to produce hot water via a buffer storage tank for a sheltered housing community in London. After a 3 week p... Read more


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...  

Our dependence on fossil fuels amounts to global pyromania, and the only fire extinguisher we have at our disposal is renewable
