Air source heat pumps pay for themselves at least 5 times over their lifetime and can reduce heating and hot water bills by up to 80%
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.
The TermoPlus® air-source heat pumps require a combination of two units – an indoor unit and an outdoor unit. The indoor unit can either be a Hydrobox, which provides heating only, or a Hydrotank which produces both heating and domestic hot water (for showering, dishwashing etc.). The TermoPlus® air source heat pump range is designed to work with Mitsubishi outdoor units that provide both heating and cooling: either a Power Inverter unit or a Zubadan unit. The main difference between the two is that the Zubadan can operate in colder environments than the Power Inverter.
Why Mitsubishi Zubadan / Power Inverter?
Mitsubishi’s Zubadan series is the market leader for outdoor air-source heat pump units due to their outstanding efficiency and reliability. The Power Inverter is one of the most established outdoor units for newer homes. For that reason TermoPlus® created two indoor units that can make the Zubadan or Power Inverter an even better investment for homeowners. Our Hydrobox and Hydrotank ranges are fully compatible with the outdoor units but also fully customisable for a higher performing installation. A Termoplus indoor unit with a Zubadan or 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 inverter technology delivers significant efficiency and unmatched real savings.
Flexible and compatible
The combination is suitable for floor, radiator and fan coil heating in new buildings or as a renovation of existing heating systems. The units can also work in conjunction with an external heat source such as a biomass, a boiler or a woodstove and take up very little space.
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 with our hydrotank as it uses an external large-surface condenser that heats water up faster due to its larger heat transfer surface.
The outdoor units can function at temperatures as low as -20°c for the Power Inverters and -28°c for Zubadans (with full heating capacity even at -15°c for the Zubadan).
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 evaporator and optimized fin spacing 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 hydrotank to replace a hydrobox / hot water heater also saves space and makes for a seamless, out-of-sight solution.
All units run an automated anti-legionella programme even without an additional electric heater and by design the hydrotank uses an indirect heating condenser to prevent the risk of refrigerant leakage into sanitary hot water.
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
With the wireless adapter installed. the heat pump can be operated with the MELCIoud app even when you are not at home. The application enables control of the basic settings of the heat pump’s operation. Optionally, the amounts of heat and power can be monitored along with the efficiency of the heat pump.
The cascade operation allows the connection and operation of up to six heat pumps into one heating system. Doing this can achieve a maximum heating power of up to 138 kW. This large amount of heating power is ideally suited for multi- apartment buildings, hotels, industrial plants and other business facilities.
The wireless remote control makes it easy to operate the heat pump from the comfort of your armchair. The device is portable and can be operated from any space without the need for wiring. The built-in sensor tracks the room temperature, constantly ensuring comfort.

New 2017 Mitsubishi outdoor units
Late in 2017 Mitsubishi redesigned some of the Zubadan and Power Inverter outdoor units. The new units have been visually redesigned and offer more silent operation. Some minor efficiency gains have also been achieved. Here is a more detailed overview of the new Mitsubishi outdoor units.
These new Mitsubishi external units are now a standard bundle with the purchase of any TermoPlus air-source heat pump. Mitsubishi has not replaced all the units in the existing range and some of the existing units are still in production. These units are competitively priced and ideal for locations where low noise is not so critical.

FREQUENTLY ASKED QUESTIONS (FAQ)
Your savings depend on many factors such as your local fuel cost, how much heating you require and what other systems are in place. Let’s consider an example of a 200m² house with average insulation and underfloor heating. With the existing heating system an estimated annual requirement of 2700lts of heating diesel at a current estimated cost of €0,9 per litre would result in a yearly cost of €2.430. If this same house switched to a TermoPlus Hydrobox / Zubadan combo with an annual consumption of 5450kWh, the annual cost would be €709 assuming a rate of 0,13 EUR/kWh. That would be an annual saving of €1721 which over the 25 year life of the product would amount to €43.025 and that isn’t even taking into account the expected rise of fuel costs.
Your hot water savings depend on many factors such as your local cost per kWh, how much hot water usage you require, and what other systems are in place. Let’s consider a conservative example of a 5 inhabitant home with a local kWh average cost of €0.13 With an average power consumption using a standard electric hot water boiler, the annual consumed power of 4500 kWhs would cost €585. With a TermoPlus Hydrotank the consumption would drop to 1100 kWhs annually costing €143. That would be an annual saving of €442 which over the 25 year life of the product would amount to €11.025, and that isn’t even taking into account the rising cost of electricity. If the cost per kWh was €0.29 as it was for an average household in Germany in 2016, the annual savings would be €986 and the lifetime savings would amount to €24.650.
Our air source and domestic hot water heat pumps are extremely easy to maintain and have very low maintenance costs. Our units only require a single annual quick service where we ensure everything is working correctly and efficiently.
Our heat pumps can installed in both new buildings and older buildings . The units can work with underfloor heating, radiators and fan coils alike. The hydrotank can replace or upgrade existing hot water facilities.
Our air-source products can be combined with an existing heating boiler, biomass or woodstove.
