Tankless water heaters are a clear winner in terms of convenience and luxury, who wouldn't want an endless supply of hot water whenever you need it? Especially with a big family and kids running around. However, Matt Risinger discusses some of the downfalls of tankless water heaters, with one of the biggest issues being scaling on the inside of the tank. Do you have a flow problem in your sinks or showers? Getting weak water pressure? You probably have scale build up on the inside of your water heater causing a blockage. The mineral deposits from the water combine with the high heat to cause calcium carbonate build up. So, what to do? Time to flush it! There are plenty of all in one kits," but really all you need is some regular old vinegar on a constant loop through the unit for 30 min to get a shiny new water heater. Watch how it's done with Risinger so you can try it at home.
