Baxi Ecogen Micro-CHP (Combined Heat and Power) boiler replacement hits UK market
Baxi has released the first micro-CHP, or Combined Heat and Power, system for the home called the Ecogen.
It’s a revolutionary wall-hung combined heat and power appliance that can provide efficient gas central heating and hot water like any other boiler, but also generates electricity for use in your home. That means it’s not only greener than traditional systems, it’s also more cost efficient too.
What is micro-CHP?
Micro-CHP is the process of generating both heat and electricity from one source. CHP has been used for years on a bigger scale in hospitals, school and office blocks, so it’s a well trialled system.
With a micro-CHP system fitted you can provide your home with heating and hot water generated at a low cost as well as two thirds of your home’s electricity requirements according to field trials untaken by Baxi. By using this electricity to power your household appliances it means you can buy less electricity from your energy supplier, potentially sell back any unused electricity, lower your electricity bills and reduce you carbon footprint.
How does the Ecogen work?
The Baxi Ecogen looks and works like any conventional boiler. However, the system uses a special Stirling engine that is heated by burning gas. The unit responds to a heat demand of up to 6kW by igniting the engine gas burner. The heat causes helium inside the engine to expand, pushing a piston up and down between a copper coil to generate up to 1kW of electricity – like an alternator in a car.
It looks just like a standard boiler, so you can have it in your kitchen, garage or utility as a direct replacement for your old boiler. And it offers its maximum cost efficiency when you use electricity as its being generated by the system, for example doing your washing in the evening when the heating is on. The Ecogen comes with a built-in energy meter so you can see how much electricity is being produced and comes with a range of controls to control room and hot water temperature to further reduce the cost of your bills.
