Domestic Single Heat Exchanger Hot Water Tank With Electric Element For Solar Geothermal Or Hydronic Systems Featuring 105 Gallon Capacity Rock Solid Heavy Duty Steel Build And Hella Efficient R21 Insulation

Sealed 105 gallon hydronic hot water tank design
✔️ Heavy steel cylinder built for solar and geothermal loops

Shipped as a single ready-to-install unit, this domestic hot water cylinder pairs a robust single heat exchanger coil with a built-in electrical backup for reliable hot water generation. Homeowners and contractors typically install it within closed loop solar thermal arrays or ground source heat pump setups to store preheated fluid efficiently.

✅ Heavy gauge coated steel shell resists corrosion
✅ Up to 3 inch R21 urethane foam lining cuts standby losses
✅ 105 6 gallon capacity matches large household demands
✅ Double jacket size reads 60 81 in 154 5 cm overall
✅ Outer body spans 29 5 in 74 9 cm for standard footprints
✅ Clearance width sits at 25 56 in 64 9 cm for tight racks
✅ Ceramic dome element delivers rapid 240 volt recovery
✅ Visible sacrificial anode rod extends vessel lifespan
✅ 1 inch NPT connection ports simplify pipe routing
✅ Five bar working rating prevents system stress

💡 What is a sealed water storage cylinder used for solar projects?

The main coil inside these tanks acts as a handy thermal bridge that moves heat from your collector loop straight into drinking water without mixing fluids. Pretty much handles the heat transfer directly, so your secondary boiler stays idle longer and your utility meter spins slower. You get steady recovery rates and lower energy bills when you run the coil at proper pressure.
- Double jacket design blocks sediment buildup inside the inner shell
- Ceramic heating element adds fast warm water during cloudy winter days
- Porcelain lining protects the steel from acidic mineral deposits over time
- Direct pipe fittings drop right into existing baseboard or radiant layouts
