Block Heaters

Does anyone know of a good product to keep the engine block water from
freezing and damaging the block during winters in cold climes ( such as
Wisconsin)? Like a dipstick heater, blanket, etc. I use water (and Water
Wetter) in my three Spridgets, but I have to keep them in an unheated garage.
I've been switching to antifreeze every winter but it's a hassle. Thanks.
