Typical air source heat pumps produce a greater output than a small flat or passive home requires. Our Eco Inverter units are the ideal option for maximum efficiency at smaller outputs.
The Eco Inverter system can produce heating, cooling and optionally domestic hot water and was designed specifically for small flats or passive homes that have lower output heating demands. With a scalable heating range between 1kW (min) and 5kW (max) the solution is ideal for flats up to 100m² or passive homes up to 250m².
Incredible efficiency and savings
Installing an air source heat pump is one of the best routes to savings with amazing returns for home and building owners. For every 1kWh of energy consumed the heat pump can produce up to 5kWh of thermal energy. Our heat pumps typically pay for themselves within 3.5 years or even less if you receive government subsidies or a grant for the system. Our air source Eco Inverter range is strictly limited to indoor units compatible with Mitsubishi Power Inverter outdoor units and provide both heating and cooling.
Why Mitsubishi Power Inverter?
Mitsubishi’s Power inverter series is the one of the most established outdoor units for newer homes. For that reason we created two indoor units that can make the Power Inverter an even better investment for homeowners. We offer a hydrobox for heating and cooling as well as a hydrotank which also heats domestic hot water. A TermoPlus indoor unit with a Power Inverter outdoor unit make an unbeatable combination of efficiency and reliability.
Guaranteed to last
TermoPlus’s very first heat pump built in 1984 is still fully operational. The minimum life expectancy of all our heat pumps is 25 years and they are covered by a 3+3 year warranty. This means that with a quick check-up every year you are guaranteed 6 years of absolute peace of mind. We’ll support our products for their entire lifetime and guarantee spare part availability.

SUPERIOR IN EVERY DETAIL
Incredible efficiency and savings
With a heaterless design there is no power requirement for an electric heater. You will enjoy the same comfort without a heating element which would use more energy. The TermoPlus – Mitsubishi combination with energy efficient Eco Inverter technology delivers significant efficiency and unmatched real savings. The use of inverter regulation allows the system to operate at various output levels as opposed to switching between on/off using a standard heat pump.
Flexible and compatible
The combination is suitable for floor, radiator and fan coil heating or cooling in passive buildings or small flats. The system can replace or supplement existing heating systems as it can also work in conjunction with an external heat source such as a biomass, a boiler or a woodstove.
Performance is boosted in our indoor units but not at the expense of compatibility – the original Mitsubishi weather compensated control is retained along with all features (see in detail below*). Switching between water and space heating is automatic and adequate capacity is ensured so that a storage tank is not required.
You will have uninterrupted hot water up to 55°C with our hydrotank as it uses a large-surface heat exchanger that heats water up faster due to its larger heat transfer surface.
With both heating and cooling the heat pump can cover all-year-round requirements of passive homes and small flats. The outdoor unit can function at temperatures as low as -15°c.
Function-packed but easy to use
A multi-functional controller provides optimal management with programmes such as automatic anti- legionella, floor drying, holiday mode and a weekly timer. Web control via app is optionally available and includes an efficiency monitoring feature. Two-zone heating is also available as an option.
Reliable and durable
TermoPlus units can operate longer than others in harsher conditions due to their larger condenser and the Mitsubishi outdoor units have a proven record of reliability in tough conditions.
Long lasting and easy to maintain
Maintenance is easy to perform since all components are easily accessible. TermoPlus hydrotanks also feature complete anti-corrosion protection through the use of a top quality enamelled water tank with a build-in MG anode.
Quiet and unobtrusive
Both the indoor and outdoor units are both extremely quiet and compact. Using a TermoPlus 120lt domestic hot water tank (DHW) along with the hydrobox also saves space with both units taking up less than 0.5m² of space
All original Mitsubishi control features are retained: Auto-defrost, automatic switching between DHW and heating / cooling, automatic anti-legionella program, control of external heating source , DHW and heating timers *, 2 zone control *, floor dry function*, monitoring of consumed and produced energy (COP)* , access via web and mobile app* , master for cascade connection* (Features followed by * are optional)
OPTIONS & FEATURE UPGRADES
Domestic Hot Water Hydrotank
The hydrobox can be replaced by a 300l hydrotank that gives you the ability to heat domestic hot water using the system. Alternatively a 120l or 150l DHW tank can be added to the hydrobox and take up very little space.
Optional Electric Heater
This upgrade is unnecessary for most users and allows the use of an electric heater to produce vast quantities of hot water for constant, intense use of temperatures of 70° and higher as well as where a backup may be needed.
Optional web control via app
The original Mitsubishi app allows you to measure the system’s efficiency (COP Monitoring) and to control the system and programs (holiday mode, floor drying etc) from PCs, tablets and smartphones.
Optional Wireless Thermostat
With the optional wireless thermostat you can manage your heat pump with greater control and make adjustments remotely.
