First integrated LG / TapHome heat pump
In family houses, we often see unsuitable heating systems – zonal regulation does not work well, the heat pump is not used for cooling, and photovoltaic surplus is not utilized. That's why we decided to develop our own solution.
Energy Optimization
The combination of TapHome control with LG heat pump and top-tier hot and cold water storage tanks brings maximum use of self-generated energy from renewable sources. Pre-programmed smart rules adjust the set points in the storage tanks according to current and forecasted solar gains.
(1) Energy from solar panels is stored in the battery storage
(2) When the batteries are charged, the excess energy is stored in the DHW tanks and hot and cold water tanks. The user can precisely monitor temperatures and graphs in the TapHome app.
(3) Excess energy is sent back to the grid.

- Support for: floor cooling / ceiling cooling / air cooling (fan coil)
- Easy connection of an additional pump group and supplementary heat source
Heat and cool production from photovoltaic surpluses
Thanks to accumulator tanks, most of the heating and cooling shifts to times when there are solar gains, and electricity is free. The stored energy is then used at night or during cloudy days.
(1) Electricity production from photovoltaics
(2) House consumption (without using accumulator tanks)
(3) Optimized house consumption
Optimization of heat pump efficiency
Since air temperatures are higher during the day in winter, we can maximize the operation of the heat pump during this time thanks to accumulation. This increases the heat pump's efficiency (COP). It also results in reduced noise from the heat pump at night. In summer, the heat pump's efficiency is higher at night, but the surpluses from photovoltaics compensate for this.
Fewer heat pump starts
This helps extend the life of the compressor in the heat pump. Longer cycles also ensure higher efficiency compared to the constant switching of the heat pump.
Optional ECO mode thanks to solar gain prediction
Adapting to weather forecasts allows us to delay heating before sunrise and only activate the heat pump during photovoltaic electricity production. Thanks to the accumulated heat in the floor, the ECO mode is almost unnoticeable.
(1) Water temperature in the tank
(2) Water temperature in the floor
(3) Room temperature
(-) Heat extraction from the accumulator tank
(+) Storage of surpluses into the accumulator tank
( x ) ECO mode active: slight reduction in comfort if sunny weather is forecasted

1) Unstable temperature due to heat pump hysteresis.
2) Necessity of having multiple open circuits
3) Frequent starts of the heat pump reduce its performance and lifespan
4) Risk of condensation on the ceiling and/or floor without a three-way valve, as the heat pump cannot produce mildly cool water
5) Insufficiently large storage tank
6) Maximum savings when combined with battery storage
