## Summary description

Unenameled insulated buffer tank KOSPEL SV-800.1 designed for hydraulic separation and thermal storage in heating systems. The SV-800.1 provides 800 litres of capacity, uncoated steel interior and external thermal insulation for reduced heat loss. Suitable for connecting boilers, heat pumps or solar thermal systems to stabilize temperature, increase system inertia and optimize pump cycles.

## Long description

Buffer tank KOSPEL SV-800.1 unenameled insulated is a hydraulic separation and thermal storage vessel with a gross capacity of 800 litres. Constructed from uncoated steel on the inside, the tank is fitted with external thermal insulation to reduce standby heat losses. The SV-800.1 is intended to stabilize system temperatures, increase thermal inertia and smooth boiler, heat pump or solar thermal system operation by providing additional water volume between heat sources and the distribution circuit.
Advantages
The buffer tank combines a large storage volume with compact external insulation for lower heat loss and straightforward integration into existing heating installations. Its unenameled steel interior provides robust thermal conduction and is suitable for standard heating water. The design reduces frequent cycling of heat sources, supports more consistent flow temperatures and can improve overall system efficiency by allowing longer pump and burner cycles.
Suitable for
Hydraulic separation between heat generators and distribution circuits
Integration with boilers, solid fuel units, gas or oil burners
Heat pump systems requiring additional thermal inertia
Solar thermal installations that need buffer storage for intermittent collection
Systems where reduced cycling and stabilized supply temperatures are desired
Key specifications
Nominal capacity: 800 litres
Construction: unenameled steel interior
External insulation: factory-fitted thermal insulation for reduced heat loss
Application: thermal storage and hydraulic separation in closed heating systems
Suitable medium: heating water compatible with uncoated steel
How to use
Install the buffer tank in a location with sufficient access for piping and maintenance. Connect the tank between the heat source and the distribution circuit following hydraulic diagrams appropriate for your system: place charging lines from the boiler, heat pump or solar circuit to the tank and discharge lines from the tank to the heating loop. Ensure correct placement of fittings, safety valves, temperature sensors and air vents as required by local installation standards. Commission the tank with a controlled fill and pressure test before regular operation, and set system controls to take advantage of the buffer volume for longer cycling intervals.
Usage recommendations
Use corrosion inhibitors or water treatment if local water quality requires it, and follow manufacturer or installer guidance on recommended operating temperatures and maximum working pressure. Periodically inspect insulation, connections and fittings for integrity and service as part of routine heating system maintenance.
