What water temperatures can i expect with this water heater?
"All depends on the water inlet temperature". The Dexpro is supplied with M22 and M24 flow restrictors. The M22 flow restrictor will limit the flow of water to 1.5 litres per minute and the M24 flow restrictor will increase the flow to 2.5 litres per minute. If the cold water inlet is 10C expect 44C at 1.5ltr min. If the inlet water temperature increases (during summer months) expect 49C at 1.5ltr min.
Can this instant water heater be fitted upside down above or under the sink?
