In 2015, commercial heating and power specialists, Adveco ( embraced

the potential of cogeneration and in particular micro-CHP (10, 20 & 25kW) as a carbon-reducing

and cost-effective way to generate electric power from gas, whilst reclaiming otherwise wasted heat which could be used to heat water or space and thereby offset costs.

“At that time, the UK grid was still dependant on the burning of fossil fuels to generate a proportion of its electricity, making local cogeneration not only attractive but a considerable help for consultants seeking to reduce carbon emissions to pass Part L for their building,” says Adveco in its latest blog (

“Today, we are evaluating the relevancy of m-CHP technology for the UK market.  The concerted effort to clean the grid has been especially successful, with the removal of coal-burning and the increased input from renewable energy sources.  This has dramatically impacted the advantages of micro-CHP, under SAP10 which establishes the acceptable figures for carbon intensity.  The recent revisions under SAP10 have shifted m-CHP as a technology, from carbon positive to carbon neutral and, most recently, negated any previous advantages m-CHP units offered in terms of reducing carbon.”

“Local initiatives such as the London Plan which is seeing widespread adoption across UK cities and the latest Government drive to address the adoption of sustainable energy within buildings have proven detrimental to several technologies, including CHP.   Larger ‘dirty’ CHP has been rightly targeted by these plans, but this activity has also undeservedly had an impact on the selection process for m-CHP.  With the Government’s ongoing focus on electricity and heat pumps, we must recognise the significant impact that has on the OPEX of m-CHP.”

“As such we have taken the hard decision to suspend the provision of m-CHP within our application designs and will no longer be selling the compact TOTEM m-CHP units.  As a business, we will continue to operate the service contracts on the units already installed, and our expertise remains available to consultants who still require CHP for their project.

In absence of m-CHP in its product portfolio, Adveco will default to hybrid gas or electric systems which leverage the high-efficiency advantages of Air Source Heat Pumps (ASHP) expanding its offering with new appliances in its FPi range.  For large scale commercial applications, Adveco has introduced the new L70 ASHP ( air source heating pump.
