Gas burner for domestic/natural gas

I've recently been using a LPG gas burner for my brewing, but find it very expensive in gas and have been thinking about getting an outlet for domestic / natural gas in my garage, but I can't find a suitable gas burner for this. Has anyone any idea where to get one?

Before I used LPG gas, I used to brew in my kitchen, but want to avoid the mess in the kitchen, so have moved to the garage.

Thanks

have a look in the commercial catering equipment you might find something suitable there
