How-To Articles


    Over the last 130 years, Weil-McLain has built a reputation of designing some of the most reliable boilers in the marketplace. If you want to leverage the power and efficiency of your boiler for domestic hot water, then the Aqua Plus 35 is a great choice. The Aqua Plus is a domestic hot water option that fits many applications and is designed for ease of installation in any system. Design features such as consolidated connection points and adjustable leg heights provide simplicity and flexibility when it comes to setting up the Aqua Plus. The large diameter and tight winding of the heat exchanger coil keep the pressure drop and recovery times low. A poly-resin top and woven vinyl outer jacket protect the Aqua Plus from wear and tear and keep the water heater looking as good as it runs.
  • 316L Stainless Steel
  • High quality, durable components provide peace of mind. The Aqua Plus features stainless steel for both its heat exchanger and its storage tank. Stainless steel resists corrosion that could negatively affect the unit's performance.
  • Efficiency-Boosting Insulation
  • Discouraging heat loss is one of the best ways to improve efficiency. The Aqua Plus has two inches of dense foam insulation that brings heat loss as low as 0.4 degrees per hour.
  • Fully Passivated and Welded Design
  • The Aqua Plus comes fully passivated and welded to protect against corrosive water conditions, eliminating the need for a magnesium anode rod.
  • Digital Control
  • The Aqua Plus features a digital thermostat that ensures precise accuracy for optimal performance. The thermostat probe is already installed for quick and easy wiring. Temperature and pressure relief valves are also standard equipment on the Aqua Plus.
