Indirect Water Heaters

Indirect Water Heaters use a boiler to heat domestic hot water. Instead of relying on their own burner, they pull heat from your existing system. That means fewer moving parts, lower energy bills, and plenty of hot water when you need it. 

Key Features

• Boiler-Powered Performance - Taps into your boiler for reliable water heating 
• Fast Recovery - Internal coil design reheats water quickly between uses 
• Insulated Tank - Keeps heat in, cuts standby loss 
• Corrosion Resistance - Stainless or glass-lined tanks stand up to wear 
• No Open Flame - Quieter and safer than traditional tank heaters

• Handles multiple bathrooms and appliances at once 
• Lowers fuel usage by eliminating a second burner 
• Operates quietly with fewer mechanical parts 
• Install & Maintenance Tips 
• Place near boiler to minimize pipe runs and heat loss 
• Flush coil once a year to remove buildup 
• Add a mixing valve to regulate output temps safely
