All the product sin this size range are intended for installation in a plant room, and thus only suitable for guest houses, small hotels, residential homes or small commercial buildings.  All require the addition of a peaking boiler and may be installed in cascade with a number of other CHP units or alternative heating sources.

Normally the electrical and thermal output can be modulated to optimise the value of electricity produced by matching it to the internal demands of the property or by maximising run hours as desired.  In some cases the products are offered on an ESCO (Energy Service Company) basis to minimise the capital invested by the customer.

Not suitable for individual homes, but, according to the UK government official definition of "microgeneration" as being any generation source below 50kWe, it is "micro CHP".

EC POWER YANMAR LICHTBLICK VAILLANT

This product incorporates a package of components including the engine/generator, a supplementary boiler, heat exchanger and integrated control system.  Rather uniquely it offers a sophisticated control with the option of heat or electrically led operation, with the engine being capable of a wide modulating range.  It is ideally suited to that difficult to address middle ground between individual homes and multi-occupancy buildings and is included here for those with an interest in small apartment blocks, sheltered housing etc. 

Both diesel and gas-fired versions are available, each with electrical output of up to around 15kWe.  The gas-fired model is based on a Toyota engines renowned for reliability and long life, whilst the diesel and biodiesel models use Deutz engines.

The Yanmar product was recently launched in the UK market following installation of around 600 units in Japan.

Unlike the EC Power unit, Yanmar offer a packaged system which is somewhat less flexible than the EC Power unit, although this should be offset by their offering the product in a range of sizes between 4-25kWe.

In late 2007 Yanmar initiated a 3 year demonstration programme of their biodiesel variant which will eventually become available with an output of 25kWe.

Yanmar packaged units, suitable for external location, are now available from ENER.G with outputs of 4kWe, 10kWe and 25kWe.

In September 2009, VW announced a plan to install 100,000 of their 20kWe "EcoBlue" mini CHP units in collaboration with energy service partner Lichtblick.

Initially units will be available in the Hamburg area, then from 2010, Lichtblick plan to expand their market into the remainder of Germany.

The units will be leased by customers who will pay an initial deposit, a monthly service charge and a favourable unit price for each kWh of heat and electricity consumed.

The most recent addition to the Vaillant CHP product range is the ecoPOWER 20.0kWe, launched in 2013.

It is aimed at buildings with an annual thermal demand in excess of 150,000kWh, such as apartment blocks, restaurants, hotels, sports halls and swimming pools.
