The CAIO8/150IND-U is a fully integrated, factory-assembled all-in-one system that pairs a 150-litre hot water cylinder with a 15 kW electric system boiler. It delivers dependable central heating alongside a consistent supply of hot water, all within a compact and efficient design with a twin-channel programmer and room thermostat. Ideal for medium-sized homes, it offers a quiet, low-maintenance, and space-saving alternative to traditional heating solutions.

Pre-Plumbed and Pre-Assembled Hot Water Cylinder

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

15 kW Electric System Boiler with Digital Display

The 15 kW electric system boiler efficiently heats the 150-litre cylinder, typically reaching the required temperature in around one hour, depending on the incoming water temperature.

The integrated digital display allows accurate temperature control and provides live operating information, including fault codes if required. Simple + / − buttons make temperature adjustment easy, while the power stage indicator shows whether the boiler is running 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 consistent temperatures across the home. Its quiet operation makes it particularly well suited to residential living spaces.

Copper Press Fittings

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

Stainless Steel Cylinder with Polyurethane Insulation

The stainless steel cylinder offers excellent corrosion resistance, reducing the risk of leaks and extending the overall lifespan of the unit. It is also less susceptible 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 two-channel programmer lets you set multiple on/off periods throughout the day so you can tailor heating and hot water to your household routine, and the thermostat monitors ambient room temperature and signals the boiler to cut in or out to maintain your set comfort levels.

Why Choose This Combination

The 150-litre indirect unvented cylinder combined with the 15 kW electric system boiler provides a compact, dependable heating solution for medium-sized homes. It delivers plentiful hot water for showers, baths, and taps, ensuring a consistent supply whenever it is needed.
