After moving into a new house with ASHP we were struggling to get the house to maintain heat especially in Winter with UFH.
This resulted in high bills and ASHP working around the clock to get to our req. temp. Sparta Mech looked at the manifold unit, adjusted pressure & thermostat, reconfig the Mitsibushi Ecodan settings for heating. They explained what was required and why we were doing it. So we now have a better understanding on how to manage it going forward.
We now have a warmer house and our bills have decreased due to a steady temperature and happy ASHP. Thankyou Sparta Mech! Highly recommended.
