The CAIO10/170IND-B all-in-one package combines a 170L hot water cylinder with a 12 kW electric system boiler, providing reliable central heating and a continuous supply of hot water in a fully integrated, factory-assembled unit. Its compact and efficient design makes it an excellent choice for small-to-medium homes seeking a quiet, low-maintenance, and space-saving alternative to conventional heating systems.

Pre-Plumbed and Pre-Assembled Hot Water Cylinder

This unvented cylinder is delivered pre-assembled and pre-plumbed, featuring two 22 mm zone valves and standard pipework connections. The factory-fitted configuration reduces installation time and simplifies plumbing work, allowing installers to complete the setup quickly and efficiently.

12 kW Electric System Boiler with Digital Display

The 12 kW boiler efficiently heats the 170L cylinder, typically reaching the desired temperature in 2–3 hours, depending on the starting water temperature.

A digital display provides precise temperature control, real-time readings, and error code notifications. The + / − buttons make it easy to adjust the temperature, while the power stage indicator shows whether the boiler is operating at 1/3, 2/3, or full capacity.

Grundfos Circulation Pump

The integrated Grundfos pump ensures effective circulation of hot water throughout the heating system, maintaining consistent temperatures across the home. Its quiet operation makes it especially suitable for living areas.

Copper Press Fittings

Copper press fittings provide secure, leak-proof joints using press-fit technology, removing the need for soldering or brazing. Copper’s natural resistance to corrosion ensures plumbing remains durable and long-lasting.

Stainless Steel Cylinder with Polyurethane Insulation

The stainless steel cylinder resists corrosion, reducing the risk of leaks and extending the system’s lifespan. It is also less prone to scaling or pitting, making it ideal for areas with variable water quality.

Polyurethane insulation minimises standby heat loss, keeping water hot for longer, improving energy efficiency, and helping to lower running costs.

Why Choose This Combination

The 170L indirect unvented cylinder paired with the 12 kW electric system boiler offers a compact, reliable heating solution for small-to-medium-sized homes. It provides sufficient hot water for showers, baths, and sinks, ensuring a consistent supply whenever it is required.
