Organic Rankine Cycle CHP

Organic Rankine Cycle CHP

The Process


ORC works by harnessing excess heat from your biomass boiler and turning it into power.


The units capture excess heat from a biomass boiler, using it in a process of evaporation.


As a thermal oil is pumped through at high pressure it begins to boil and turns in to gas.


The gas flows through the patented twin screw expander, which causes a generator to spin and produce power. 


The gas is then cooled back into it's liquid form to begin the process again.




ORC is reliable

Each ORC unit can provide a continuous supply of up to 65kW of electricity. 


To get the most out of ORC you need a year round requirement for heat and power.


When the demand is there the technology makes a substantial cut to costs whilst generating income.

Move beyond fuel as power


ORC is completely fuel free.


The technology allows you to create cost free, emission free power from equipment you already have.


If you want to join those already using ORC but don't have a heat source, it's a fantastic option to combine the technology with a waste wood biomass system. By choosing this, you gain access to the cheapest heat and power available on the market, whilst opting out of rising energy prices.


Whether installing a whole new heat and power network or optimising on what you already have, ORC will let you tap into the CHP uplift tariff. Click here to find out more.

Choose energy that won't harm the environment


Wood chip is a renewable, carbon neutral fuel. 


You can also burn C grade waste wood which has traditionally received a gate-fee for removal.


Switching to CHP means you can cut your CO2 emissions and receive an income from government incentives.



Switching to ORC – what’s involved

ORC is easy to install and with one of our servicing plans will run reliably for many years.


However, to make sure you get the best return on your investment it’s important you install the right unit for your needs.


We can help:

  • Design a unit that will best suit your site and energy needs
  • Supply, install and commission the unit
  • Provide on-site training
  • Provide off-site monitoring in conjunction with ElectraTherm
  • Provide telephone and on-site support
  • Service the unit under an annual contract

Free Site Survey


To provide you with reliable and cost-effective energy ORC CHP must meet a number of legal, technical and site considerations.



We can survey your site to make sure switching to ORC will work well for you.



There’s no obligation and it’s completely free.
To book a survey call us on 01600 463 008.

Connecting to the grid


The local distribution network operator (DNO) must give permission for a CHP unit to connect to the public electricity supply.


They may need to assess the impact of the unit on the network and may stipulate design and operating requirements, securing their permission can be a complex process.


We know the DNOs in our local area well and have worked with their staff so often we’re on first name terms, so we can make connecting to the grid quicker and easier.
