Sussex Solar did a fantastic job specifying and installing solar panels and an air source heat pump (to replace our existing gas boiler), that met the requirements of our old house and our budget. From the initial survey, to the end of the installation the Sussex Solar team were friendly, positive, well informed and diligent. The workmanship (plumbing and electrical) was of very high quality and carried out neatly and precisely. It was a pleasure to have the team working at our house, they brought great energy and had a considerate, thorough and careful approach to their work. The results have been excellent. The system has now been in place for 11 months and has worked brilliantly. The house feels warmer than when we used a traditional gas boiler, our bills are lower and we are using only renewable electricity. We live in a late victorian house with modern radiators and an unusually sized hot water tank due to space limitations. A few firms looked at our situation and told us that an air source system was unlikely to be practicable, requiring a large air source unit and substantial new plumbing. However, Sussex Solar were able to specify a modern air source heat pump (the Vaillant AeroTherm plus with R290 refrigerant) that works with our existing radiators and hot water tank to provide efficient heating and hot water without extensive and costly re-plumbing. We couldn’t be happier with the solution Sussex Solar have installed for us and how well it has worked.
