Dear Sir/Madam

Re: Request to extend warranty on HIU

As a collective, we, the residents of Ascot House are writing to request that the warranty of our Heat Interface Units to be extended for a further two years from when the building warranty end.

Since moving into Ascot house, most of us have experienced multiple incidents of leaks from the HIU. Some have reported over six incidents under one year. However, the leaks have never been fixed permanently. We suspect the problem is not a mere coincidence but rather at fault with the manufacturing/installation of the HIU.

Hence, we request that all the HIU should be inspected throughly for leakages and the warranty to be extended for another two years. We should be allowed to use hot water in the property without needing to worry about our HIU leaking every few months.
