Bosch AWMS 11-15 Electric Boiler Indoor Module with Integrated Solar Management

Future-proof your domestic energy profile and seamlessly merge multiple renewable heat sources using the Bosch AWMS 11-15 indoor electric boiler unit. 

This multifunctional internal module is specifically engineered to pair with the heavy-duty outdoor compressor units of the Bosch Compress air-to-water heat pump range, matching the 11, 13, and 15 kW capacity options. The special "S" configuration stands out by incorporating a factory-installed thermal solar exchanger coil alongside dedicated solar management circuitry within the primary controller. This setup allows you to smoothly bridge your system into solar collector arrays for free hot water production throughout the summer months. The unit features a built-in 185-liter water cylinder equipped with a smooth, stainless steel heat exchanger coil for peak thermal transfer.

Comprehensive Internal Array and High-Capacity Booster

The Bosch AWMS 11-15 serves as a complete all-in-one solution where the vast majority of vital installation hardware comes securely packed within the sound-insulated and thermal-jacketed frame chassis. The module arrives pre-assembled with a modulating, variable-speed charge pump, a system expansion vessel, and required safety valving. To confidently manage heavy thermal loads in larger properties or during severe winter peaks, the unit features an integrated 15 kW electric immersion heater providing step-controlled modulation as an auxiliary booster to guarantee uninterrupted indoor comfort.

Advanced Digital Control Hub with App and WiFi Readiness

The indoor unit is managed by an integrated digital control station that automatically optimizes the real-time interaction between the air-to-water heat pump, the immersion booster, and the connected solar grid to keep utility costs strictly minimized. The standard package comes delivered complete with a matching room thermostat and an IP network module. Connecting your system via WiFi grants you full freedom to monitor operational status, program heating schedules, and adjust temperature thresholds remotely via a dedicated smartphone app. A load monitor is also built in to protect your electrical network.

Standard Sizing Footprint and Clean Top Alignment

Featuring a standard 600 mm width and a depth profile of 660 mm, the Bosch AWMS 11-15 fits neatly into standard laundry rooms or mechanical plant cells. All mechanical connection ports are positioned cleanly on top of the enclosure to ensure an organized, vertical, and highly accessible pipe layout for the mechanical installer. Please note that upon installation, the system must be supplemented with an external circulation pump for the space heating loop alongside basic safety valving such as a check valve, manifold piping, and a filling loop. Due to the high power capacity, a 25 Amp electrical fuse rating is required.
