加拿大采购需求：水冷式加热器，加热器

I'm interested in the coolant heater and would like to know if there's a way to adjust the water or coolant temperature setpoint. I've seen several comments about this feature, and I'm curious if it was an issue with an older version. I'm planning to use this unit for a small ambulance van conversion, specifically for providing domestic hot water and hydronic heating through a fan coil system. Additionally, could you provide any technical details on how to set this up using a brazed plate heat exchanger? I also noticed a sale price on your US website, but I'm unsure if it's available for Canadian customers. I found a dealer in British Columbia, so I'm wondering what options I have. I really appreciate the innovative design of your products; they're quite popular up here!
