Since 1939

Electrowarmth as a business has been manufacturing heated mattress pads right here in Danville Ohio since 1939.

Made in USA the business was purchased from the Crise brothers in 1997 by the Grindle’s.  The Crise brothers were the sons of the original inventor of the heated mattress.

The Grindle’s have made many improvements since that purchase in 1997. Two of the most dramatic changes were making most of our units fitted and making all but our 12V units ETL approved.

We pride ourselves in customer service by shipping our customer’s order within one day of receiving the order, which means having all models in inventory at all times.

We are unique in that we manufacture more models than anyone else in the market, plus we custom manufacture if needed.

Some of our unique models are a dual control doubles, single control queens, short queens, and many extra long models.

Can’t find a model to fit your bed?  Call us and we will custom manufacture one to your exact needs and specifications!
