company logo

I need a company logo but its tricky, the company name is Norfolk Burners, its a heating service and installation firm and the main area of work I want is biosmass boilers and multifuel stoves however the company will also be servicing oil boilers with a view to selling the cutomer the biomass boilers (renewable heating) once their oil boilers reach the end of there life. I guess to sum up its a heating firm from norfolk where all sources of heat are combustion appliances hence norfolk "burners" As its the biomass and multifuel stove side I want to focus on which are classed as renewable heating sources I want the logo to incorporate something green I know thats rather vague but its the whole green energy thing I perceive becoming the big selling point when they come under the RHI grant scheme next year. I had a vague idea in my head of the outline of a house in green or maybe a green tree beside it and some sort of flame inside it with a chimney above. However i'm not a designer so i'm open to any ideas : )
