Hidden healthcare savings

Using a REOMED medical isolation transformer is a cheap and easy way to protect patients and use less energy. Despite the many cost saving measures introduced over the last decade, healthcare providers are still some of the most energy intensive users of electricity in the UK. The NHS, for example, spends on average over £750m annually, spread over 2,300 hospitals, 10,500 general practices, as well as numerous additional trusts.
