In 2006, 18 years ago, the first HONE renewable heating & hot water system was installed in the west of Ireland under the brand new SEAI government grant program.
(Note: This was a HONE Generation 4 Thermal system, and we are now at Generation 6 Thermal & Electric; we did not deploy Generation 1, 2, 3 except in research)
This system integrates with the central heating and hot water systems, so the energy harvested is used for radiators and hot water usage.
Whilst HONE is the highest certified thermal technology worldwide today, the lifespan of renewable technology, once it is installed, must also be a key factor. HONE systems have a design life of 50 years, which is unprecedented in renewable technologies historically.
Many traditional solar hot water panels typically expire from 7 years onwards and it would be rare for them to produce any energy by year 18. Unlike traditional solar hot water panels, HONE does not use any degradation elements and as such will remain in operation at full perfromance for decades.
This highlights just how much energy is being produced by a 18-year-old HONE system and more evidence of HONE’s incredible long-term performance and operational reliability.

Real-time production data is the only viable evidence, and as can be seen, an 18-year-old Gen 4 HONE Thermal system is still producing energy in line with brand-new HONE installations.
The HONE Gen 4 system has received its mandatory 5-year fluid services.
