Every new system comes with one years warranty including a drain-down in the Winter which consists of draining down the system with a compressor (if accessible), leaving it in a safe manner and minimising the risk of frost damage.
A start-up in the Spring is also included which consists of testing the complete system and making adjustments to ensure that it is up to a good standard. This process dectects any system faults so that they can be rectified ready for the Spring.
