How does Yanmar CHP Work?
Our CHP applications involve the recovery of wasted engine heat to produce useful thermal energy and electricity. To do this, natural gas or propane fuel is combusted in a Yanmar engine to generate electricity, and the heat that is normally lost in the engine’s exhaust system is recovered to provide heat for domestic hot water, in-floor heating, space heating, swimming pools, dehumidification, and other similar applications. Which Yanmar CHP systems are available in Propane? Yanmar's 5 kW & 10 kW Combined Heat and Power systems uses an internal combustion engine, powered by propane, to produce both heat and electric power. |

How efficient our Yanmar's CHP systems compared to conventional systems?
The unit efficiently utilizes up to 88% of the fuel burn versus 33% burn rate of conventional means, from-the-grid sources (electricity and natural gas boiler).
Yanmar CHP Systems have the following advantages over traditional energy delivery methods of centralized power via the gird (power plants) and onsite gas use:

Yanmar CHP Systems have the following advantages over traditional energy delivery methods of centralized power via the gird (power plants) and onsite gas use:
- Onsite generation (or distributed generation): Electricity is generated close to the point of use (next to your building), helping to avoid transmission and distribution losses that occur when electricity travels over power lines. Electricity can also be available even when the grid has failed due to storms or other factors.
- Waste heat recovery: Thermal energy from space heating, domestic hot water heating, pool/spa heating dehumidification or process applications goes unused in centralized power plants as waste, but in a Yanmar CHP application, it is used to offset boiler or other heating device usage.
- Simple integration: Yanmar CHP systems can be easily integrated into various electrical and thermal systems in residential or commercial applications throughout Canada. This applies to both new construction and retrofitting into existing homes or buildings.

How efficient are Yanmar Combined Heat and Power systems?
Yanmar’s CHP thermal energy recovery technology captures the heat created when the system generates electricity. While this heat is typically wasted during conventional power generation (gen sets), all Yanmar CHP systems effectively recovers it, avoiding energy losses that stem from the generation of heat and power from separate systems. This energy can then be used to heat or to pre-heat your domestic water supply, provide radiant heating or assist with desiccant dehumidification. Because our Yanmar CHP system was designed to generate heat and electricity at the point of use, it also prevents the 60% or more energy loss that occurs when electricity travels over power lines. Additionally, our system relies on built-in, high-efficiency components, including a proven rich burn Yanmar natural gas engine, permanent magnet generator and inverter for high reliability and lower installation and building integration costs. In fact, our inverter matches the power it generates with centralized power. When you combine these factors, the CHP system overall efficiency is 88%, which translates to reduced operating costs and a greater return on investment over the life of the system. Can you combine a Yanmar CHP system with another? Yes, up to 16 units can be combined off one controller. Options may vary per model. How quiet are the Yanmar CHP systems and can they be installed inside a building? With an operational noise output range from as low as 51 dB(A) to only 62 dB(A) in our larger units, Yanmar's CHP systems are extremely quiet, working well in both indoor and outdoor environments. Our anti-vibration mount provides an additional level of noise reduction, resulting in quiet performance that goes undetected. |
Can you power a Yanmar unit using Renewable Natural Gas?
Yes. Be carbon neutral and used Renewable Natural Gas. Throughout many communities, local farms, landfills, water treatment facilities and municipalities have teamed up with their utility companies to capture biogas from decomposing organic waste and purify it to make Renewable Natural Gas. This sustainable energy source (RNG) is injected into their distribution system and shared with the customers, both residential and commercial. Will Yanmar’s CHP work with Solar Photovoltaic systems? Yes, Yanmar CHP systems easily integrate with solar PV system as one complete hybrid solution. What happens when the power goes out? Yanmar provides uninterrupted power even during a blackout. Yanmar CHP systems feature a Blackout Start option, ensuring your heat and electricity remain uninterrupted even during a blackout. Yanmar’s high-efficiency built-in inverter (not in all models) converts the CHP’s generated electrical output into DC voltage and frequency with built-in protection, and the ability to provide complete power for buildings located in remote areas or off-grid. What is the difference between a generator and Yanmar’s CHP system? Yanmar’s systems are designed to provide energy 24/7/365 and any additional power may be shared with the grid (net-metering) whereas a standard generator is built for one purpose only, backup power in case of an emergency. Your Yanmar CHP system also provides the comfort of both heating and electricity in one unit. Environmentally friendly, Yanmar’s units can run of both natural gas and renewable natural gas, costing less to operate and carbon free.
