Water Tank Heater Manufacturer

Frequently Asked Questions

• Q: What is the best sheath material for a water heater?

• A: For clean water, copper is the most efficient due to its excellent thermal conductivity. For mildly corrosive water or when longevity is key, stainless steel is better. For highly corrosive or saltwater, titanium is the ultimate choice.

• Q: How can I prevent scale buildup on my water heater elements?

• A: Using a low watt density element helps. Additionally, installing a water softener or regularly cleaning the elements can prevent scale buildup and maintain efficiency.

• Q: Can I use a standard flange heater in a potable water tank?

• A: Yes, as long as the materials are compatible. We recommend using stainless steel elements and a food-grade gasket to ensure compliance with potable water standards.

• Q: Do you provide heaters for pressure vessels?

• A: Yes, our flange and screw plug heaters are designed to be pressure-tight when installed correctly with the appropriate gasket. Please specify the pressure rating of your vessel.

• Q: What is the advantage of an over-the-side heater?

• A: It's very easy to install and remove for maintenance, as it doesn't require a special nozzle or flange on the tank. It's ideal for retrofitting or open-top tanks.

• Q: How do I size a heater for my water tank?

• A: You need to know the volume of water, the desired temperature rise, and the heat loss from the tank. Our team can perform a detailed heat loss calculation to determine the required kW.

• Q: Can your heaters be used with deionized water?

• A: Yes, but deionized water can be aggressive to certain metals. We recommend using stainless steel or titanium sheaths for this application.

• Q: Do you offer explosion-proof water heaters?

• A: While water itself isn't typically flammable, we can build heaters with explosion-proof enclosures for the electrical components if the overall environment is hazardous.
