Buderus is now offering heat pump add-on packages with all the components required for retrofitting in the “air-water heat pump outdoor unit, hybrid hydraulic group, hybrid manager, controller and other accessories” portfolio. The boiler thus becomes a future-proof and eligible heat pump hybrid system. The packages are available for the Logano plus GB212 and Logano plus KB192i series gas condensing boilers and for the Logano plus KB195i oil condensing boiler.
One number is enough
The heat pump extension sets make the ordering process easier for contractors. With just one order number, installers receive everything from Buderus that is required for the expansion to a heat pump hybrid system. The heat pump external unit included in the package is available with power ratings of 6, 8 or 11 kW. Packages with the Logalux SH290 RS heat pump DHW cylinder including boiler cylinder piping are also available. In order to expand a condensing boiler into a hybrid heat pump system, tradespeople set up the heat pump unit outside. The heat pump and boiler are then hydraulically connected to each other via the hybrid hydraulic group supplied in the package. If a photovoltaic system is installed, the self-generated electricity can be used to operate the heat pump outdoor unit – an additional contribution to CO2 savings.
Intelligent hybrid manager included
The HM200 hybrid manager included in the packages efficiently networks the condensing boiler and heat pump external unit. It controls operation and integrates the heat pump into the Logamatic EMS plus control system of the heating system. Depending on the selected control strategy, the hybrid manager decides whether the heat pump and/or the condensing boiler should provide the heat. End customers can choose between several control strategies such as “Cost” and “CO2”. The cost-optimized strategy uses the energy prices to calculate which heat generator is currently working more cost-efficiently. The CO2-optimized strategy selects the heat generator that is currently more energy-efficient or CO2-reduced. The scope of delivery also includes the pre-assembled hybrid hydraulic group with LIN circulation pump, filter, ball valve, sensors and other components.
