Every Feature Designed to Save You Money
MelPump connects to your heat pump and automatically optimizes it for the cheapest electricity and maximum solar self-consumption - while giving you deep analytics to extend your system's lifespan.
Pay Less. Heat the Same.
Smart Energy Mode connects to dynamic electricity tariffs (Nordpool, Octopus and more) and automatically adjusts your heat pump's behavior during expensive peak hours. When prices drop, everything returns to your preferred settings - automatically.

Let the Sun Pay Your Bills.
MelPump automatically analyses solar production data for your exact location and activates the heat pump when solar output is at its peak - storing free energy as heat for later. No sensors, no extra hardware. Start saving from day one.

Automatic solar-peak pre-heating
Tank and buffer are pushed to higher temperatures during the most productive solar hours - stored heat covers the evening and night.

Zero hardware required
No inverter integration, no extra sensors. MelPump uses external solar data sources for your location - sign up and it works immediately.
Short-Cycling Kills Heat Pumps. We Stop It.
Short-cycling means your compressor restarts more than twice an hour - and it has to happen consistently over many days to be a real problem. MelPump collects compressor frequency data and shows it on a clear chart, so you can spot the pattern over time and fix it before it causes lasting damage.

Compressor frequency chart
Visualize compressor Hz over time - identify short-cycling patterns instantly and adjust your settings to eliminate frequency drops.

Defrost monitoring
Track every defrost cycle. Excessive defrosts signal configuration issues or installation problems worth addressing.

Electric heater runtime
Booster heaters consume 3–5× more energy than the heat pump alone. Monitor their runtime and minimize unnecessary use.

Heating mode optimization
Compare Heat Curve, Auto Adaptation and Constant Temp modes side by side to find your optimal configuration.

Avg COP
Your Heat Pump. Fully Visible.
More data than the manufacturer's app, presented in a way that actually helps you make decisions.
All-In-One Dashboard
Daily KPIs, live device state, energy chart, operation mode timeline and real-time energy predictions - all in one screen.
COP Monitoring
Track your Coefficient of Performance daily and over time. A higher COP means more heat for less electricity - we show you exactly where you stand.
Temperature Reports
24-hour and monthly temperature charts grouped by hour or day. Understand how outdoor temperature affects your pump's efficiency.
Energy Reports
Daily, monthly and yearly views of consumed vs. produced energy. See your 14-day trend and understand where your electricity goes.
Push & Email Alerts
Set your own thresholds for temperatures, error codes and efficiency metrics. Get notified the moment something needs your attention.
Remote Control
Adjust settings, force hot water, change modes and control your heat pump directly from your phone - anywhere, anytime.
