The Microgeneration Certification Scheme

MCS and RHI

Effecta boilers are all carefully designed to be simple to use and most models feature self-cleaning elements to reduce the need for maintenance. All boilers under 45kW in this range are MCS accredited and naturally meet all European standards, making them suitable for RHI applications. 

Defra approved, RHI Eclist, HETAS approved and made in Sweden

Reduced Emissions

In order to achieve MCS accreditation, the Komplett III has been designed to have emissions significantly lower than the required limit of 30g/Gj particulates (PM) and 150g/Gj of nitrogen oxide (NOx).

Meeting (and beating) these standards means that the Komplett III is perfect for commercial or domestic RHI projects. 

Boiler PM NOx
Maximum Emissions 30 g/GJ 150 g/GJ
Effecta Komplett III Range 7 g/GJ 99 g/GJ

Self-Cleaning

Your Komplett III is designed for minimum maintenance, with all convective air channels and combustion parts being self-cleaning. You’ll only need to have your boiler cleaned and serviced every 15-25,000kWh, which should only be once a year in domestic application.

FAQs

Wood Pellets

What are wood pellets?

Wood pellets are made from compacted sawdust or any other waste produced from sawmills and other manufacturers.

What is the calorific value of wood pellets?

It’s 4.8kWh per kg, meaning you only need one third of the storage space that you would need for chips. Plus you get three times as much heat.

  • Wood Chips = 250KG/m3
  • Wood Pellets = 650KG/m3
How much do I need, compared to oil?

1 litre of oil is equivalent to 2kg of wood pellets.

What is the cost of wood pellets?

You can expect to pay between £180 - £220 per tonne.

Where is the nearest supplier of wood pellets?

We always recommend using the fantastic Biomass Suppliers’ List (BSL) for a comprehensive list of high quality suppliers across the UK.

Can I use any kind of pellets?

The pellets will need to be ENPlus A1 or A2. These are 10-12mm long and 6mm in diameter. Your wood pellets need to be dry, clean, mechanically robust and possess an ash content defined by appropriate standards. They need to be able to flow freely and delivered via a pneumatic system. Check out this handbook from HETAS for more information about wood pellets.
