[Equest-users] Infrared Heaters

Im not sure what your talking about as far as renewable energy, but ive always modeled infrared by dropping the zone temp setpoint by ten degrees, setting the fan energy to zero and making the furnace 100% efficient.  Some times I lower the heating design temperature as well.

Bill,

Do you have a chart that shows how much renewable energy the unit consumes
and then uses to create heat? What you need to do is create the item in 2
parts. Its renewable component, which might be a solar collector and then
you set up a radiant heater in the room either as baseboard or as your
system in that zone.The thing that I have noticed while modeling is there
are 2 things you are looking at.. products in your building and how they
consume energy, by amount and efficiency. The second is what are you doing
to replace the energy... renewable or are you pulling it from the grid. The
model does not care where it comes from as long as when you use the
renewable it is as efficient as you say it is. I typically use PVWatt
calculator and do manual calculations because someone taught me that. You
can also set up a collector in the utility&economics tab under photovoltaic
modules. This is where you will need the solar information on your
collector.

The weather file needs to be correct because this is where it is pulling
your solar radiation data from watts/meter squared or watts/feet squared.

Hope this helps. (Easier to do by hand)

Thanks,

Hello,

Does anyone have any experience modeling ceiling hung infrared heaters in
eQuest?

Thanks,
