Samad Power Ltd, a privately owned, pre-revenue, engineering company, based in Milton Keynes (UK), is developing a range of innovative, new micro CHP (‘combined heat and power’) domestic gas boilers, which have the potential to replace the current generation of condensing boilers almost completely. Over the next 5-10 years, Samad management believes the ‘micro-CHP boiler’ could become the de facto industry standard across the UK and Europe.
Samad’s first product to market will be the Turbo Green Boiler ‘TGB’ - a wall-mounted 17 kW(th) / 2.9 kW(e) system, which is currently at TRL stage 8 and is designed for use in larger houses and other properties such as care homes and hotels. Commercial trials are due to start within the next few months with the first TGB sales expected before end 2019. The second product will be ‘TwinGen’ – a slightly smaller10 kW(th) / 2 kW(e) wall hung unit, currently TRL stage 5 with the first product sales expected before end December 2020.
Micro combined heat and power (known as micro-CHP, or m-CHP) comprises a range of technologies which are designed to produce both heat and electric power simultaneously within individual houses and small-scale commercial premises.
To date, most new m-CHP heating and power systems have suffered from three principal drawbacks: Reliability issues, Substantial up-front cost and Unfamiliar operating cycles – which is why Samad Power’s micro-CHP system is intended to be a straightforward replacement for existing gas boilers – at an acceptable price.
Both ‘TGB’ and ‘TwinGen’ are effectively gas boilers with built-in micro gas turbines, which generate electricity. Although they will cost slightly more than standard condensing boilers, they will be simple to install and will not require any replumbing or changes to a customer’s existing central heating system.
The UK is the largest domestic boiler market in Europe, (and the third largest in the world, after China and South Korea) with 26 mn installations and approx. 1.7mn unit sales per year. EU boiler sales (incl. UK) total 8.1 million units per year.
Samad Power’s micro-CHP technology offers two clear and compelling advantages. For domestic consumers it means a dramatic reduction in overall utility bills - up to 30% without a ‘feed-in tariff’ or any other form of government subsidy. For the UK economy as a whole, it means more efficient utilization of natural gas, the UK’s principal source of non-renewable energy - with the added bonus of reduced pressure on the electricity grid during periods of peak winter demand.
There will also be considerable environmental benefits. Assuming a TwinGen boiler generates, on average, 1,261 kWh per year, each unit installation should typically save 0.6 tonnes CO2 emissions per house per year. So, if Samad Power can achieve 10% UK market penetration – i.e. a total of 2.5mn TwinGen installations – it means a saving of approximately 1.5 million tonnes CO2 per year. Plus there is the added benefit of reducing demand on the UK electricity grid at peak periods.
