<div>Dear trnsys users,</div>
<div> </div>
<div>I am simulating and studying the behaviour of a central heating system of a residential building with gas boilers. For the boiler I'm using type 700, where combustion and boiler efficiencies are inputs. I need these values as a function of the intlet water temperature and the part load ratio for the model to work and I don't find this data in any boiler catalog. Only partial data like the boiler efficiency at rated power.</div>
<div> </div>
<div>If somebody had any cataloge with this data I would be very thankful. Or maybe somebody knows any manufacturer who could provide me.</div>
<div> </div>
<div>I know it's not a doubt or question about trnsys itself, but I'm a bit desperate.</div>
<div> </div>
<div>Thanks in advance!</div>
