"ISO Energy installed a Ground Source Heat Pump system in our house in the Summer of 2013. They are a company that dot every i and cross every t. They have polite, professional and efficient workmen, use the best quality hardware available for the job, and we were very happy with the installation. Any problems or queries were dealt with immediately, and I would without doubt recommend them as an installer of GSHP. And the house is warm!"
