The HONE technology is currently going through a detail evaluation process for a European Union Environmental Technology Verification. HONE is likely to be the first renewable technology ever to get an ETV. This process is designed to allow innovative new technologies be evidenced, certified and promoted by the EU for their full benefits. This process will certify HONE emmisions, performance and environmental benefits to an EU standard. Even though HONE currently delivers a major renewable contribution on emissions reductions, software models such as EPC and other building energy rating software don't have a heat engine component as it is a propiatary HONE technology and don't currently model the full benefits of HONE. This ETV process will provide an EU underwritten statement of verification.


A simple example of how this should work is where a HONE system is currently installed in a new building today can easily meet an A2 (<50 kWhrs/m2) or A3 (<75 kWhrs/m2) rating, historical studies show that a HONE system installed B1 rated new build actually performs to a good A1 (passive) standard when you evaluate the energy bills and it does this without having to build a passive (expensive) house design. After the ETV process is completed, this B1 house mentioned above should technically be able to get a new EPC (BER) certifcate which will now show the corrected value of A1 for the property which has HONE installed.


This ETV process has meant a number of very long term studies of the technology have been taking place to build up historical and verifyable information from deployment of HONE. This includes full multi year auditing of energy bills, statements, etc.


The data below is from one such studied retorfit installation and is current as of 15th July, 2016.


The project is a 2001 concrete cavity wall bungulow, nearly typical of many homes built in Ireland. Here are the model types that apply to this case study. If your home is similar to one of these property types listed below, then this detailed study applies to your property.


1967 - 1977 - NOTE the cost of a Heat Pump Upgrade at €25,515 and payback of 18.6 years, (Compressors used in HP's have expected life span is 15 years !!)

1978 - 1982

1983 - 1993

1994 - 2004


Specifications on the design:

• HONE/OIL combination system. (HONE Daylight is the primary heat/boiler source, original oil (2001 Firebird) as backup when needed)

• 12 standard and double radiators with 300L hot water cylinder.

• Cavity walls pumped in 2009 and attic insulation unchanged at 50mm.

• Full remote control and monitoring system.

• HONE system reports house temperature to all devices including phones.


Summary information:

This property had a HONE Gen 4 installation since 2009 and a Gen 5 system upgrade since 2012. (Gen 5 was offically launched in May 2016 to the market). The results are in the table below and the full audit trail detail is underneath it. The current data covers the use of Gen 5 Thermal/Electric.


This home is heated by HONE ONLY with Boiler backup and does have HONE electric as it has a combined HONE Gen 5 Theral/Electric system.

The home is a normal family home occupied and used 24 hours a day, has no electric shower or immersion and fireplaces have been sealed.

As there are children in the home, and there is no tumble dryer, the heating radiators are used all year round for drying clothes.

As the home was built with 1 single heating zone installed in a concrete slab floor, no zoning was possible. all the radiators are ON or they are all OFF.


The main key results are an average saving of 77.9% per year over 5 years of operation. An average COP of 634.8 per year over 5 years of operation and a payback of 5 years..

Note: There is a noticeable difference between 2015 and 2016 and this is explained due to the drop in home oil price in 2015, the

home owner continued to spend their typical annual budget on oil but as the price lowered, they bought much more oil than

they needed and hence in 2016, they still had lots of surplus oil left over, this is why 2015 savings dropped to 58% and 2016

savings are up at 96.5%.

# The fuel costs and efficiencies change but in the guide above are representative of information in the public domain and have been taken from various sources. The table is deigned to reflect the overall view.

# Heat pump emissions are high and this generally surprises people. Heat pumps are electric heaters, they consume electricity and you get heat. Electricity is made from fossil fuel and more recently has been reducing with wind inputs, etc. Coal powered electricity from some of the largest power stations on the grid produce a lot of this electricity, like Drax in the Uk and Moneypoint in Ireland. A power station burns approx 2.5 kWhrs of fossil fuel for every kWhr of electricity delivered to your home and this is why electric heating systems which are big loads have high primary emissions and this has a big impact on climate change. The UK mandates a minimum COP of 2.9 to meet a renewable element.

# An additional item is that all electricity emissions in Europe typically fall under the ETS (Emission Trading Scheme) and Governments have no liability for these emissions. In contrast non-ETS emissions (heating, transport & Agri) are liabilities on each EU government from 2020. Hence it is easy to understand why Governments want people to switch to electric heating. It reduces their non-ETS emissions liability (fines).

# Wood Pellet CO2 contains the input CO2 for making the pellets, drying, processing, pressing & distribution.

Payback using a HONE heating & electricity system

  • A HONE system is designed and sized according to the energy profile of the home, building or application. An older house will have a bigger HONE system and the newly renovated (existing home upgraded with HONE) payback below is the actual data from one of our long term case studies. The initial investment is bigger at €18,000 but the actual savings which are being validated annually are in the graph below. Over 30 years, the home owners will save €127,000 euro.

  • In the 2nd new build (2016) graph below, the savings over 30 years are a smaller €37,000 but the initial investment for a new build home (much improved building regulations) is pro-rata much smaller at €5,500 per detached home.
Once installed, a HONE system produces free energy, heating & electricity from the day it is installed and most of the money you were spending stays in your wallet forever..



Frequently Asked Questions

What is HONE ?
HONE is a Nano Technology Heat engine which harvests FREE photons of light from the sky. It can be used on domestic buildings, commercial and industrial buildings and processes. HONE is the first and only Photon Harvesting Nanoscience ever developed.
Can I get this technology from any other supplier ?
No, this is a proprietary technology developed and owned by us. It is the ONLY Nano-engine daylight technology in the heating and cooling space. The science has been a long research project covering two decades. It is a costly and time consuming technology to create but its outstanding performance makes payback periods much quicker.
What about Mechanical Heat Ventilation Recovery ?
This is a no brainer in our opinion. With an airtight low energy home, you will need a ventilation system or you will have mould and condensation in addition to potential health issues. If it is properly designed, this invisible system will also manage the space heating for you throughout the building. Don't cut corners on this step, it is key to a great design.
What about under floor heating, I am told this is the way to go ?
Under floor heating is a good idea in some countries and projects but may not suit yours. It is about 4 times more expensive to install than using radiators. Certain countries which have changeable weather should always be careful about under floor heating as it is a storage heater. The concrete slab wrapped around your under floor heating needs about 3-4 hours to warm up and the same to cool down. In places such as the UK and Ireland where you can experience 4 seasons before lunchtime, under floor could be an expensive mistake.

Imagine, it is raining heavily and you have your under floor heating running and then the sun comes out and starts shining in the windows of your nice new house, the temperature will climb rapidly and you won't be able to stop your heating system for 4 hours and all that energy will make your home very uncomfortable for several hours. By using radiators, you can turn your heat on instantly and turn it off instantly; thus using the correct amount of energy and keeping your home at the right temperature. This is worth considering especially if your building has lots of glazing.

Using radiators in a modern A3 or better means only a few slim radiators are needed, typically only 6 in a 2,000 sq ft home and not under any window so your walls are clear. The design considerations have all changed.

What are the main advantages with HONE
The advantage with HONE is that you can reduce your consumption of heating oil, gas or any other heating fuel by up to 100% depending on your location. i.e. you switch to FREE Photon powered heating and hot water production and all you need is overcast cloudy skies or better for it to work. See our performance history webpage for daily proof even in December
Why do you make a sample of your Daylight Powered systems available online LIVE ?
We are not afraid to prove how powerful HONE is and we believe that renewable heating technology should not be purchased on a "promise", hence our motto, PROOF, NOT PROMISES. We put our money where our mouth is when it comes to proof.
What is payback like ?
As you can imagine, the fuel is FREE for life and the technology is very powerful so payback is really quick. There is no need for incentives, grants or other supports to create a great and quick payback. In a new build project, the payback is really fast and your annual heating bills are only €/£100-€/£200 a year.
What do I need to do to my building ?
HONE works with any building of any age. You can use it with radiators, ducting systems, under floor or any existing heating or cooling infrastructure. You do not need special radiators or other such modifications. HONE is a FREE energy system that works at oil or gas boiler temperatures.
How is it installed ?
The installations are easy and straight forward. A retrofit heating system typically takes 2/3 days and a hot water system 1 day. A commercial system will take longer. HONE systems don't use any additional buffer volume as HONE is a very high temperature technology and interfaces as your boiler does.
How is your COP so high ?
The COP is very high as we are harvesting a full spectrum of light and using a Nano-engine to turn that into high volumes of free heating & cooling energy. COP's are typically higher than 1:250 and can go as high as 1:400. There are proprietary technologies we have developed and own which make this possible.
How have you made such advances over other renewable heat technologies ?
Simple, oil and gas have been so cheap for so long that little or no innovation has taken place for the last 150 years in energy science. Heat pumps were invented in the 1860's and solar hot water panels went on the market first in 1891. These technologies are based on old outdated science. As energy keeps getting expensive, new technologies will be developed.
Can I avail of Government Grants and tariffs ?<
Yes, HONE is a thermal renewable technology and the HONE collector matrix falls under the EN12975 standard and any grants, etc that are issued under that standard which means any solar thermal supports..
What warranties are available ?<
Yes, HONE is a thermal renewable technology and the HONE collector matrix falls under the EN12975 standard and any grants, etc that are issued under that standard which means any solar thermal supports..
What type of quality is your products made to ?<
Our product standards are military grade. Picture better than Premium German standards. Our testing is done by TUV Rhineland and we only use aluminium as a base metal. Every component in the whole system is manufactured to the highest standards possible.
