Buffer tank KOSPEL SVK-100 unenameled with insulation, vertical connections, 100 L

KOSPEL SVK-100 unenameled buffer tank with insulation and vertical top connections is a 100-litre thermal storage vessel intended to accumulate heated water from boilers, heat pumps or solar collectors. The tank evens out temperature fluctuations, reduces short-cycling of heat sources and optimises hydraulic balance in central heating and domestic hot water systems. The outer insulation is factory-installed to limit heat losses while the unenameled inner surface is designed for systems where internal glass-lining is not required.

Advantages

The tank’s vertical top connections allow compact installation and simpler piping layouts in systems with limited floor space. Factory-installed insulation provides improved thermal retention and reduced standby losses. A 100-litre capacity offers a practical buffer volume for small to medium residential heating systems, supporting better modulation of boilers and heat pumps and stabilising temperatures delivered to radiators or underfloor heating.

Suitable for

• Buffering output from gas, oil or biomass boilers
• Integration with heat pumps to reduce cycling
• Storing excess thermal energy from solar thermal arrays
• Small residential central heating and DHW systems
• Light commercial installations requiring thermal buffering

Key specifications

• Nominal volume: 100 litres
• Orientation: vertical
• Connection layout: top (vertical) connections
• Inner surface: unenameled (suitable for non-lacquered applications)
• Thermal insulation: factory-fitted outer insulation
• Typical applications: central heating, DHW buffering, solar thermal storage

How to use

Install the buffer tank on a stable, level base and connect supply and return lines to the designated top connections following the system design. Fit necessary safety and control devices such as expansion vessel, pressure relief valve, temperature sensors and circulating pumps according to local regulations and manufacturer guidance. Commission the system by filling, venting air from the circuit and checking for leaks. Ensure piping and controls are sized to match boiler, heat pump or solar array output and to allow efficient circulation through the tank.

Usage recommendations

Use corrosion protection or appropriate water treatment when required by system materials and water quality. Select pipe diameters, pump capacity and control strategy that correspond to the heating source and load. Regularly inspect insulation and connections for damage or thermal losses, and follow national rules for installation and maintenance of heating equipment.
