How did we ever manage without an Air Source Heat Pump?
Customer Service
From survey through quote and into installation we have been very impressed with GreenGen and the ASHP system. The plumbers that came to us were knowledgeable and worked cleanly and efficiently despite several challenges outside their control. We now have a full handover pack and service plan and are benefitting from both regular and reliable hot water and heating, as required, plus saving money on our fuel costs. Would recommend to anyone in this area
