ECOHHR High Heat Retention SOLAR
Storage Heaters

The smart Elnur SOLAR High Heat Retention storage heater allows the use of energy from solar panels and other renewable sources, Wind, Geothermal, Ocean etc to reduce heating costs using free energy from renewable energy sources. When there’s not enough renewable energy production, it uses cheaper off-peak power to charge and provide heating.

Elnur's SOLAR High Heat Retention is the first storage heater on the market that can utilise a household’s solar or other renewable generation and converts the renewable energy into stored heat for delivery gradually into the room as required, providing the household with free heating. If the surplus production is insufficient to provide the heating desired, Elnur's SOLAR HHR can function as a conventional High Heat Retention storage heater by completing the charge during off-peak hours.

    HHR SOLAR is an intelligent storage heater capable of utilising your photovoltaic production surplus, converting the solar energy into stored heat and gradually delivering it to the room, providing the household with free heating.

    • – First High Heat Retention solar storage heater to the market
    • – Transforms available surpluses into heating
    • – Integral management via wifi
    • – Clean and sustainable heating
    • – Savings in consumption and use of solar panels installation


    Solar manager patented technology

    Elnur ECOHHR SOLAR incorporate the Solar Manager technology, the latest of our innovations, developed and patented by ELNUR GABARRON.

    • – Detects the surplus from photovoltaic self-consumption installations.
    • – Intelligent distribution of energy to the installed devices.
    • – Adapts the output of the heaters to the energy available.
    • – Operates according to the established priorities and the different set points per room.


    ECOHHR SOLAR can operate as a back-up system to the main heating, consuming only the surpluses from the photovoltaic installation fed into the grid. These surpluses will be converted into stored heat and then later allocated to the room according to the set comfort needs.
    If the generation of surpluses is not enough to provide the heating required, ECOHHR SOLAR can operate as a single heating system and complete the charge during off-peak times.

    The integral management of heating and the distribution and use of the solar production, as well as the control of the ECOHHR SOLAR storage heaters, is possible through the G Control System and the free Elnur Gabarron Wifi Control app.

    • Display is not coming on?Untitled-1
      This can be caused by a few different things. The first things to check would be one of the 3 isolator switches. The Economy 7 and 24hr supply switches and then the switch on the back of the heater. If this does not work we would then recommend checking the fuse board to see if the breakers are all still on. If this does not solve the issue we would suggest calling an electrician to check the fuses in the spurs to ensure power is going to the heater. If power is going to the heater but still no display you will need to call us on 01942 670119 or email technical@elnur.co.uk
    • Storage heater is only lukewarm?Untitled-1
      This would suggest your SSH storage heater is reducing its own charge percentage to reduce running costs. This is a normal process for the smart heater, it will work out the most efficient way to run following your set program and temperature. If you are not comfortable with the current heat output then we would suggest increasing the set point temperature to allow a bigger charge. How to set Temperatures on your ECOSSH?
    • Are Elnur storage heaters supplied with cable?Untitled-1
      Our Storage heaters do not come with cable. They do not come with cable as the distance from a fused spurs varies too much to supply a set length. The qualified electrician would usually supply the cable needed to wire in your storage heater.
    • Do I need to leave a gap above my heater?Untitled-1
      Yes, a 15cm gap needs to be left above any Electric radiator, Storage heater and Panel heaters. This is to help the convection of the radiator and prevent over heating. Unlike central heating radiators, electric radiators, storage heaters and panel heaters can not be covered as it poses a serious fire risk.
    • What is the difference between manual and automatic storage heaters?Untitled-1
      Storage Heaters Charge up over night using the 7 hrs of economy 7. Manual Storage Heaters charge for the full 7 hours regardless of how much heat it used the previous day. Automatic Storage Heaters calculate how much heat was used the previous day and work out how long they need to charge for. For example, If an automatic storage heater only used 5 out of the 7 hours of stored heat, when it comes to the next charging time the storage heater will wait 2 hours then will charge till it is full. On Average this facility can save you up to 15%.
    • Are these heaters a direct replacement for my current heater?Untitled-1
      Not exactly no. Modern storage heaters do differ to the older traditional storage heater. Most noticeably due to the fact that they now require a constant (24 hour) power supply to function. This can be done with either a single meter which has a dual rate supply which allows you to set the charging periods on the heater to match your economy rates OR if you have a separate supply and meter for your economy you would require a secondary supply (24 hour) to the heater.
