New member - Homeowner - Query on Kestons

[CK-TW]

Hi there

I have a Keston C55 which has failed. Looking to replace it. Trying to get a consistent opinion on whether the 'new' Keston Heat 55 would be a reliable alternative. House has 20 column rads (inc towel rails) and 4 floors (3k sq ft overall). If I understand correctly from engineers who have quoted (2), it is not over specced re capacity. Really just want a handle on reliability of Keston Heat 55s.

Thanks in advance
