An Energy Efficient Heat and Power Solution

What is ecopower®?

The ecopower® micro-cogeneration system provides heat and electrical power in a cost effective and environmentally friendly manner. Using a natural gas or propane fueled Marathon engine, the ecopower® captures thermal energy for space heating, domestic hot water, pools and other applications. Electricity produced by the generator is either consumed in the building or excess can be sold back to the utility if net metering is available in your state.

How ecopower® Works

The ecopower® uses heat generated by an internal combustion engine to produce between 13,000 - 47,000 BTU per hour of heat while simultaneously co-generating 1.2 - 4.4 kW of electricity. The ecopower® is a thermally driven system and the greatest savings coincide with higher heating loads.

Offset Electrical Costs

With the technology of ecopower®, the unit can supplement the thermal load of the building all while creating electricity. Installation of ecopower® will likely not change your natural gas or propane consumption, but provide you the benefit of lowering your electric bill.

Key Features

Long Maintenance Interval

The engine’s superior design allows the engine to run for 40,000 hours with 4,000 hours between service intervals. The maintenance includes changing the oil, oil filter, air filter, spark plug and spark plug cable.

Powered by a Marathon Engine

Proudly made in the USA, the Marathon Engine is the prime energy source for ecopower®. Clean burning natural gas or propane contributes to the long life and thermal efficiency. The Marathon Engine is like no other.

Typical Installation

A typical installation consists of an ecopower® microCHP system, buffer tank, boiler and hot water tank. The software inside the system integrates the ecopower® with the buffer tank, modulating the system output to match the buildings thermal needs. An indirect hot water tank can be hooked up to satisfy water heating needs.

Parallel Operation

Up to four units can run in parallel to provide more thermal and electrical output. Parallel operation is ideal for larger applications like multi-family buildings, hotels or any buildings with a larger thermal need than one unit can supply.
