Thanks Jeff,
I've been looking at those before, but, with shipping and tax they end up half what I paid for my heat pump. Looking for a more budget friendly option. Secondly, I understand that a grossly oversized single hx will destroy my precious compressor due to low speed/flow of R410a. I read that there are minimum flow rates for 410 due to lubrication issues. This is why my hx has 3 circuits with thin lines among other things. Can anybody comment on the minimum flow rate ? At least this is what I read and I am trying to avoid lubrication problems.
Indeed it looks like the Chinese market is a good candidate even price wise, some offer this hx with free shipping:
Aliexpress.com : Buy free shipping fish piano music game carpet Fashion Children's Educational Toys fish Music crawling mat, baby toys blanket from Reliable carpet stair suppliers on Ningbo Haishu Chosen Trade Co., Ltd.
Not sure if the specs are ok. Will keep looking.
If oversized, I understand it is better to have several smaller hxs in parallel due to min flow rate required for 410a.
Cheers,
F
