The CAIO12/150IND-B all-in-one package includes a 150L hot water cylinder paired with a 12 kW electric system boiler, delivering reliable central heating and stored hot water in a fully integrated, factory-assembled unit. This compact solution is perfect for medium-sized homes seeking a quiet, low-maintenance, and space-saving alternative to traditional heating systems.

Pre-Plumbed and Pre-Assembled Hot Water Cylinder

This unvented cylinder comes pre-assembled and pre-plumbed, with two 22 mm zone valves and standard pipework connections. This design reduces on-site installation time and simplifies plumbing work, making it easier for installers to fit.

12 kW Electric System Boiler with Digital Display

The 12 kW boiler efficiently reheats the 150L cylinder, typically bringing it to the desired temperature in around one hour, depending on the starting water temperature.

A digital display provides clear control over the water temperature and shows real-time readings along with any error codes. The + / − buttons allow easy adjustment of the temperature, while the power stage indicator shows the boiler’s current operating level (1/3, 2/3, or full capacity).

Grundfos Circulation Pump

The Grundfos pump ensures hot water circulates reliably throughout the heating system, maintaining even temperatures across the home. Its quiet operation makes it ideal for living spaces, enhancing overall comfort.

Copper Press Fittings

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

Stainless Steel Cylinder with Polyurethane Insulation

The stainless steel cylinder resists corrosion, helping to prevent leaks and extending the lifespan of the unit. It is also less prone to scaling and pitting, making it suitable for areas with variable water quality.

The polyurethane insulation reduces standby heat loss, keeping water hot for longer and improving energy efficiency, which can help reduce running costs.

Why Choose This Combination

Together, the 150L indirect unvented cylinder and 12 kW electric system boiler provide a reliable and compact heating solution for medium-sized homes. It delivers enough hot water for showers, baths, and sinks, ensuring it’s available when needed.
