Hi Russ, Appreciate your time and and feedback! So does this mean rather then me being so rigid with my calculations i should base them in worst case scenario? In the eye of design and not hyperthetical, what should it be based on? My understanding was a gas water heater was sized on heating...

Good afternoon Russ, I work in sales and would look like to further my understanding as i also find it very interesting! I have identified average flow rates from a building services book i brought, (i am also waiting to take delivery of a physics thermodynamics book too!), anyways the flw...

Without having a lot of experience in sizing/thermodynamics i would have thought that my investigation would be based on peak demand? I have also done a calculation on re-heat over an hour and a temp rise of 30 needing an kw input of 35kw?

Hi Bystander Thanks for the reply to my question, i think i have moved on a little since my post, but would appreciate any feedback. I have mocked up a scenario where a gas fired water heater is being used in a hospital for 75 people. From cold to heat the hot water the following has been...

Hi Guys, I am aware how to calculate flow rate Q (c x dt), but when sizing a direct gas fired water heater there is no dt but of course need allow for temp rise, but what parts of information can be known and unknown and how would i even start to put a formula together? Ultimately i would like...
