Time for my questions now.
I am putting in a Lochinvar whn 085 into a warmboard heated house and an 80 gallon indirect. The house is 1800 square feet with a heat loss of 39,000. I ran this late last night so not sure if I got all the info right. I haven't used this heat loss program for awhile, and am sure I am missing something in the insulation detail for the crawlspace, so am pretty sure the heat loss is less. But at this point the heat loss is not so much the concern. I will work that out later.
I have been following some of the posts about piping this unit and am not sure the best way to go. It sounds to me like the best way to go to get the most out of this system is to pipe it direct. I am pretty sure I can get the customer to go with a 0-10vdc pump. The other way would be like a Taco vt2218 controlled by the zvc boxes from the manifolds.
I am not sure which will get me the best results for the system and the customers money.
The heat program I used is for Wirsbo, so it can only calculate for Quictrac, which uses 5/16" tubing, therefore the head loss is not right at this time.I will try and run it later to see if I can get better outputs.
The smallest zone will be down as low as 300 btu for a guest bath, but most likely that zone will on with the main line zone.
So, 15-58, vt2218, or 0-10vdc pump? Or, do I really need to pump it primary-secondary? Head loss doesn't seem to justify that though.
Thanks,
Rick
