## Description

Built with high quality stainless steel 316L and 99.9% copper, these plate heat exchangers produce a counter-current flow to maximize heat efficiency. This boiler plate heat exchanger is highly efficient due to the corrugated plates which produce a high, turbulent flow in a true counter-current direction. With their compact size and reduced material content, they can be the most economical heat transfer choice.

Review: The 30 plates exchanger does a really good job at heating our domestic hot water tank for our family of 4. Easy to install with PTFE teflon. Highly recommanded. Their customer service is also very good.
Review: Purchased this heat exchanger to heat the water going into the hot water heater. The exchanger works very well as our wood burner is normally set at 180 degrees. The 26 plate exchanger is a bit much though for our family of 3. The water from the water heater get extremely hot. When the boiler is heating the water for the water heater, the furnace does not get as hot as when the hot water from the boiler is going straight to the furnace. The heat exchanger is easy to install. Our hot water heater has not used any electricity since the heat exchanger has been installed. Well worth the money.
