efficient and tailor-made system that suited our needs It helped us to get planning permission Straightforward installation – messy drilling but once that process was over with Econic could quickly move on to plumbing and fitting Worked well to retrofit into our project site Systems are housed outside plus the hot water system easily fits into the boiler cupboard of each house We intend to use GSHPs in the barn conversions, phase 2 of our development, as we are so impressed with them The systems are expensive but for high quality technology and cheaper, sustainable heating we think this is worth it
