Installer Info

The boiler must be installed by personnel authorised by the relevant national authorities, in compliance with the applicable laws and regulations.
This boiler is suitable for heating water to a temperature below boiling point at atmospheric pressure. It must be connected to a heating installation and/or a domestic hot water distribution network, which must always be compatible with its performance and power.

This appliance must only be used for the purpose for which it has been expressly designed. Any other use is considered unsuitable and therefore hazardous. The manufacturer shall not be considered liable under any circumstances for damage caused by unsuitable, erroneous or irrational use. Remove all the packaging and check the contents are complete. In case of doubt, do not use the boiler. Contact your supplier. Keep the packaging elements out of reach of children, as they can be dangerous.

When you no longer wish to use the boiler, disable the parts that could be a potential source of hazard.


The boiler must be installed in a sufficiently ventilated site, away from humidity. It must be located so that the air grilles on the premises are not obstructed and normal boiler maintenance is possible even if it is placed between items of furniture. One metre of free space must be left above the boiler for this purpose. Locating the appliance in a part of the garage where it cannot be struck by a vehicle.

Hydraulic installation

The hydraulic installation must be made by qualified personnel. The applicable installation legislation is to be complied with, and the following recommendations should also be taken into account: – It is obligatory and essential to install an anti-condensation valve (shunt valve) with the boiler, to prevent any water condensation in the heat exchanger. If this requirement is not complied with, EKOPOWER’s guarantee of the appliance will automatically be null and void. – The inside of the installation piping should be thoroughly cleaned (flushed) before switching on the boiler.

We recommend inserting cut-off valves between the installation piping and the boiler to simplify maintenance tasks. – Leave adequate free space around the boiler for carrying out any maintenance and repair operations. – Drain valves and suitable devices for correctly bleeding the air from the circuit during the boiler filling stage should be fitted. – Install all the necessary safety elements (expansion vessel, safety valve, etc.) to comply with the applicable regulations for the installation. Make sure there is adequate expansion area in open vented systems tank. – If the boiler is installed at a lower height than the heating installation, it is recommendable to create a siphon at the boiler outlet, to prevent the installation from heating up due to natural convection when heating is not required.

Circulation pump is in the correct location and circulating the water in the correct direction.


The EkoHeat boiler must be fueled by EN PLUS certified wood pellet. The EN PLUS certificate assures that the fuel’s humidity levels and calorific value are ideal for optimum boiler functioning. If this requirement is not complied with EKOPOWER’s guarantee of the appliance will automatically be null and void.

The following points should be taken into account for correct fuel storage: – The stored pellets should be kept dry all year round. – The applicable legislation in each country for correct fuel storage must be complied with.

Wood pellets are made from wood shavings and sawdust and are used in highly efficient and convenient automatic wood boilers. Because they have a low moisture and ash content wood pellets burn very efficiently. What’s more they are compact and easy to store. Typically pellets come in bags (ideal for stoves or smaller boiler systems) or are delivered in bulk by truck (ideal for boiler systems with bulk stores). Wood pellets can be ordered from local fuel merchants.

Pellets facts (Typical)

  • Dry matter content 90-92%
  • Ash content 0.5%
  • Diameter 6-8mm
  • Length 30-45mm
  • Density 650 kg/m3
  • Volume 1.54m3/tonne pellet
  • Energy 4.7 kWh/kg pellet
  • Benefit 1kg wood pellet replaces 0.41kg of light fuel oil

Wood pellets are upgraded or refined wood fuels which have been produced from sawdust, grinding dust, shavings, bark or cutter chips by drying and pressing. No additives are needed to produce them. Lignin released in the pressing process binds the wood material. They are compact and easy to store and use for fully automatic burning in wood pellet boilers or stoves.

Good quality wood pellets with a moisture content of 8% will have a calorific value of approximately 4,700 kWh/tonne.
