American Alternative to European NIBE Exhaust Air Heat Pump + DHW Combo Units? (post #205715)

I was working in Architecture a number of years ago and found the NIBE exhaust air heat pumps that also serviced domestic hot water needs and space heating needs with an integrated water tank and backup electric heater.  At the time the products were not available in the US, and I'm having trouble finding them available now.

Does anyone know an American company or supplier that can provide units like this?  I am especially fond of the NIBE's for the tall and compact footprint and the specific integration to ventilation air and hot water needs in one appliance.

why not just use an ERV or HRV?

Better Standards (post #205715, reply #2 of 7)

European standards for tight, insulated, low energy homes are better than in America.  Studies on the "Passive House" standard showed a requirement to tie exhaust air to heat recovery, and in some some sense micro, distributed heating and cooling in ducts or otherwise. 

So, since I design small super-green homes, that European appliance market is appealing to me.  What i like most about NIBE is the tank-in-a-tank system that can service both deomstic hot water and space heating water from a single compressor...

I took a look at your "Activity" in your Profile.  It shows no posts made except for the one you made here.  I can't help you find them, but maybe if you tried again, in either your own post or perhaps in answer to someone else's question (if that's what you were trying to do).

It's certainly a bummer, but maybe the suns recent activity has something to do with it.

 

If you're just looking to place a free ad here about your boat building business, not a good idea-if you run an ad, you should pay Taunton for the pleasure.

 

thanks.

can you post a better copy (bigger) of the text portion of your example?

thanks, having trouble reading the words-the quality isn't good enough for these eyes.

So, instead of me trying to blow it up a bit, could you handle the chore-once and done for all.

 

thanks again.

I'm pretty sure I saw an "efficient electric home" design recently that included a heat-pump water heater.  But I think it was an AC/heater combo, not a heater/heater.

Have you considered ducting the exhaust thru a mini-split with the intake thru the indoor condensor?
