Interested in views on where the line should be drawn between ‘local water heating appliances’ and boilers - the terms used in C/AS2 4.10.3. We are increasingly seeing continuous hot water units (ie. Infinity) being used to replace traditional large water storage boilers in existing plant rooms which don’t already meet the requirements of this clause in terms of fire rating etc. This obviously comes up in new builds also.
In some situations there may only be one unit, but in some cases there will be a number of individual califonts on a manifold supplying hot water for central heating or a larger number of plumbing fixtures throughout a building. This has become more difficult to interpret consistently.
I would like to know how others are dealing with this. Thanks.
