The CAIO10/150IND-U is a fully integrated, factory-assembled all-in-one system combining a 150-litre hot water cylinder with a 10 kW electric system boiler. It provides reliable central heating and a consistent supply of hot water within a compact, efficient design, complete with a twin-channel programmer and room thermostat. Ideal for medium-sized homes, it offers a quiet, low-maintenance and space-saving alternative to conventional heating systems.

Pre-Plumbed and Pre-Assembled Hot Water Cylinder

This unvented cylinder is supplied fully pre-assembled and pre-plumbed, including two 22 mm zone valves and standard pipework connections. The factory-fitted arrangement reduces installation time and simplifies plumbing, enabling quick and efficient system commissioning.

10 kW Electric System Boiler with Digital Display

The 10 kW electric system boiler efficiently heats the 150-litre cylinder, typically reaching the desired temperature in around 2–3 hours, depending on the incoming water temperature.

An integrated digital display allows precise temperature control and provides live operational information, including fault codes when required. Simple + / − buttons make adjustments easy, while the power stage indicator shows whether the boiler is operating at one-third, two-thirds or full output.

Grundfos Circulation Pump

The built-in Grundfos circulation pump ensures efficient distribution of hot water throughout the heating system, maintaining even temperatures across the home. Its quiet operation makes it particularly suitable for residential environments.

Copper Press Fittings

Copper press fittings provide secure, leak-free joints using modern press-fit technology, removing the need for soldering or brazing. Copper’s natural corrosion resistance ensures long-term durability and reliability.

Stainless Steel Cylinder with Polyurethane Insulation

The stainless steel cylinder offers excellent resistance to corrosion, helping to reduce the risk of leaks and extend the unit’s lifespan. It is also less prone to scaling and pitting, making it suitable for areas with varying water quality.

High-density polyurethane insulation minimises standby heat loss, keeping water hot for longer, improving energy efficiency and helping to reduce running costs.

Two-Channel Programmer and Room Thermostat

The twin-channel programmer allows you to set multiple on/off periods throughout the day, enabling heating and hot water schedules to be tailored to your household routine. The room thermostat monitors ambient temperature and signals the boiler to operate only when required, maintaining comfortable and consistent indoor conditions.

Why Choose This Combination

The 150-litre indirect unvented cylinder paired with the 10 kW electric system boiler delivers a compact and dependable heating solution for medium-sized homes. It provides ample hot water for showers, baths and taps, ensuring a reliable supply whenever it is needed.
