Havenwise is an easy-to-use control and optimisation system for your heat pump. Connect via our app in just a few minutes, no installer needed. We connect directly to your internet-connected heat pump, so most users need no extra hardware. Havenwise automatically learns how your home heats up and cools down. Our smart software takes into account your energy tariff, local weather, and your comfort to keep your home warm and water hot for the lowest possible bill. Havenwise works great with time-of-use tariffs to shift your heating out of expensive peak periods and into the cheapest times of day. For homes with solar panels, we can shift usage to warmer and sunnier periods. For batteries, time-of-use optimisation can be toggled on and off depending on your preference, to take advantage of tariffs or keep your heat pump running low and slow for maximum efficiency. Our support is always available to answer questions and keep you informed and confident about your home heating needs.
