Damien Mullins is a specialist. Along with his thorough understanding of the physics of fluid movement he has the practical knowledge of a very experienced plumber. This equips him to be at the leading edge of low energy heating. He knows what will work. Damien will think through heating configurations issues with client, architect and builder – combining well-tried technologies with novel and ingenious adjustments that meet the particular wishes of the client. After installation, as the building performs through cold winters and hot summers, he will adjust and fine tune.

We upgraded from an oil boiler to a Danfoss heat pump from Heat Doc in 2011 and its absolutely unbelievable 24/7 comfort & permanent hot water on tap and at a substantially lower running Cost.

Eileen Jones, Kilkenny.

Heat Doc are among the few that really understand the mechanical system requirements of a passive or low energy house. From the water supply, heating right down to the ventilation they really are specialists in their field.

Andrew Nagel, Bagnalstown, Co Carlow.

We were building a new house and were confused with which heating system we should install. Heat Doc came highly recommended to us and we found their team a pleasure to deal with from the initial heating system design through installation, commissioning and after sales service. We would highly recommend Heat Doc to everyone.

Margaret Murphy, Celbridge, Co. Kildare.

We had solar panels installed in 2007 by another plumber and couldn't find anyone to service them, we heard about Heat Doc and organised a service visit. They immediately understood the system and now its working better than ever!
