Remeha floor-standing boiler has monobloc aluminium heat exchanger
Remeha’s Gas 220 Ace floor-standing range of condensing boilers achieves Class 6 for NOx emissions and has an exceptionally high output for their physical size. There are four models with outputs from 160 to 300 kW and modulating down to 20% of full output. Gross seasonal efficiencies are up to 97.7%.
The monobloc heat exchanger is cast from a single piece of aluminium, which is almost half the size of previous models.
All connections and pipework enter the top of the boilers, enabling them to be positioned in space-saving configurations. There are cascade options for up to four boilers in line and up to eight in a back-to-back arrangement.
For ease of servicing, these boilers have an internal service light, a new inspection glass, and a cleaning tool and gasket to remove any dry scale on the cleanable aluminium heat exchanger.
The easily connected condensate drain is underneath the boiler, rather than inside, so it does not need to be dismantled for access.
An innovative feature is the 2-level entry control platform with time and temperature controls supplied as standard and an enhanced, back-lit panel for simple input and control. Built-in 0 to 10 V and volt-free contacts enable these boilers to be connected to any BMS.
Wheels enable a boiler to pass through a standard doorway and be easily manoeuvred into final position.
Multiple flueing capabilities provide flexibility of installation in new and existing buildings.
An optional high-temperature secondary return features optimises operation with renewable technology and variable-temperature systems.
