A high-quality giant! The 1 1/4" NPT threads are the only downside. However, a G-thread screws onto it well enough when you use SikaLock thread sealant. A ready-made insulation jacket would be a great accessory, but you can also insulate it with Armaflex sheet if you don't mind a bit of DIY tinkering. Excellent value for money.

Very good quality, very good water performance, water inlet temperature for hot water 17 degrees and water outlet 42 degrees, on the other hand water inlet from the boiler 45 degrees water outlet to the boiler 42 degrees, it has a very good performance. I highly recommend it

Der leistungsfähigste Wärmetauscher, den man für kleines Geld haben kann. Wir haben ihn verwendet, um die Wärme von einer Wärmepumpe an unseren Heizungskreislauf zu übertragen und dazu im Kreuzgegenstrom angeschlossen. Er bei für etwa 6 kW Wärmeleistung keinen messbaren oder fühlbaren Temepraturabfall zwischen Eingang heiße und Ausgang kalte Seite. Die Anschlüsse eignen sich für einghanft 1 1/4 Zoll oder auch für flach dichtend mit 1 1/4 Zoll Überwurfmutter. Dann muss man ihn aber spannungsarm einbauen und eine Centellen-Dichtung verwenden, weil die Dichtfläche nur etwa 3 mm breit ist.

I installed an outdoor wood boiler in 2015…. I want to say I purchased the same heat exchanger back then for $250+. 10 years later the exchanger scaled up, and wasn’t as efficient. The only thing I have to gripe about was that this unit had 1 1/4” MPT treads in it. My old one had 1”. Couldn’t find stainless reducers at my local Menards, so went with Galvanized which I hope I won’t regret. Overall, very happy with the install, no leaks, and a super warm house again in Northern Michigan.

The unit is very nice, the brazing looks good and the straps are useful. However, it s NBSP (straight) not NPT for all of the 4 connections. NBPS is very hard to get a good seal to NPT, and also results is almost no thread grab. I am taking off 4 stars because of this so people are aware of the NBSP vs NPT issue. If you are installing in a location where some leaking is OK, this is the unit for you! Left is stainless nipple (with taper) right is unit (no taper).
