Hydronic Flow Metering for Bill Separating

john Cockerill_2

There was a fellow in NY who tried to bill his tenants for heat based upon a metering system. The courts threw him out. I do not know more than that. But check your leasing and the housing rental regs.

Hydronic Flow Metering for Bill Separating

I've heard of some type of flow meters that can be installed on each zone of a multi-zone hydronic system for useage measuring. If anyone can help, I am researching the possibilities for a customer in RI who needs to properly adjust rent prices. Lots of them. Thanks, all!

Can't help you with flow meters, which tend to be expensive, but if the system has circulators for each zone, the easiest thing to do is to put a run time meter on each pump. You can record minutes or hours run and total them up and use percentages to figure heat use.

These guys meter the run time of the circs or the EDR of steam systems in my area (SLC, UT.) They work great if you do the math as far as the heat factors & heatloss go.

Legality

I would think that any device that measures something that is being sold would have to be listed with a testing agency of some type. Seems like circulator run times, while indicative of use would not provide an accurate enough measure of true energy transfer. Flow rate and delta T measurement would be the only way to be completely fair.

If it's more of a friendly how to split the bill thing I suppose circ. run times would be fine, if flow rates and deltas were consistent.

To bad people are so bad at conserving things that they don't have to pay for.

Here's a link to a company I researched a while back. They use metering and delta T to figure heat loss. Seemed a good system. http://www.istec-corp.com/ Couldn't sell it at the time . It would have paid for itself many times over by now. Let us know how you make out . Always wondered how these systems last 5-10 years down the road.

Check out Siggy's column in Sept PM mag

it talks about BTU metering.

This is very common in Europe. Caleffi builds a nice metering system in a cabinet. It meters heat, DHW and cold water all in one box.

I saw some installed in an apartment building we visited in Italy. They mount in the hall ways outside the units for ease of service and inspection.

Caleffi may import them is enough interest is shown.
