Hello all, i am doing work for a customer who has asked me what the reheat time of a 250 litre cylinder is. To be honest after all the years of doing plumbing this is a question that i have never been asked before because usually if you need a hot water cylinder then it is what it is, you just need to deal with the reheat time regardless of what it is.
I have however experienced that these cylinders tend to heat up relatively quickly (estimating around half an hour). The customer had various questions with regards this system and so i contacted my usual wholesaler to see if they could retrieve these answers from the hot water cylinder supplier, all the questions were answered satisfactorily apart from this one where the rep said that usually they calculate it at a litre per minute which i am not buying to be honest because we are then talking 4 hours to heat a 250 litre cylinder haha.
So...i was wondering if any of you had a definitive or accurate answer to this query or are we all just in agreement that you are talking about half an hour, which i personally would deem to be a reasonable amount of time. The cylinder is going to be run off of 2 immersers simultaneously as we will not be dealing with off peak, so when the customer turns on the hot water it will be running with 2 6kw immersers, there is not going to be a coil in it.
Any help on this would be appreciated...thanks in advance
