In Microwell we exclusively apply epoxy based GoldFin protection for all our products because it is just the best. GoldFin creates hydrophobic layer which repels water. In this case the heat pump in colder weather will freeze lot later than standard Bluefin and will defreeze itself faster than Bluefin. This will provide simply more heating. GoldFin is also superior in livelihood of the unit in salty air (coastal application) or sand. It will simply last longer.

Titanium Grade1 – no compromise

In Microwell we understand that livelihood of a heat pump is key factor when deciding for its purchase. Titanium Grade 1 ASTM B265M consists of at least 99.2% titanium, with small amounts of oxygen, iron and other compounds (carbon, nitrogen and hydrogen) up to 0.8%. The low impurity levels contribute to its exceptional corrosion resistance. This material also leave no trace, no odor and is neutral to its environment. All Microwell heat pumps are equipped exclusively with this type of titanium in their water exchangers.

Massive heat exchange area – up to 1.2m2

We apply extra surface of up to 1.2m2 of corrugated (twisted) titanium spiral. You can’t go around the physics, you can embrace it. The extensive heat exchange surface provides unprecedented performance and livelihood for each single Microwell heat pump.

Salt + Chlorine + UV + Electrolysis

Each Microwell heat pump is designed to work with various kinds of water, including those treated with chlorine, salt, electrolysis, sulfur or UV. This is mainly thanks to exclusive Titanium Grade1 ASTM B265M titanium tube material used inside water heat exchanger. Standard stainless steel or copper exchangers used in domestic heat pumps would typically last 1 month in pool application with water treated by chlorine. With Microwell heat pump you can be sure that materials used are designed for long harmless operations.

4 modes for maximum comfort

Black inverter heat pump is pre-programmed to operate in 4 modes – AUTO, BOOST, SMART and ECO. Each of them is set to provide different final heating or cooling output while keeping an eye of overall efficiency. Should you like to minimize heating time you may choose BOOST. Should you like to minimize energy bill, you may choose ECO. Or simply you can choose from our 2 fully automated modes AUTO and SMART targeting maximal comfort.

RS-485 Modbus

RS-485, in the context of the Modbus communication protocol, is a widely used interface for industrial control systems and automation applications. RS-485 is a standard for serial communication that allows multiple devices to communicate with each other over long distances. Each Microwell pool heat pump is equipped with RS-485 port based on ModBus protocol. You can program the heat pump to be voice-controlled and also integrated into your smart house control system. The distance to your Microwell heat pump has never been so close.

Microwell swimming pool heat pumps are designed for heating or cooling the water in pools and hot tubs at minimum operational costs.

HP 1100 BLACK Inverter is a powerful heat pump suited for pools up to 60m3 in volume.

HP 1100 BLACK provides 8.6 kW of heating capacity at conditions of air temperature 26°C, water temperature 15°C and air humidity 70%. This heat pump can provide up to 11.5 kW of heating at typical conditions of air temperature 27°C, water temperature 26°C and air humidity 80%.

COMPACT version

COMPACT heat pump is one device, that provides desired water temperature in the pool. It requires only water connection, power supply and convenient place to be installed. Simple and affordable system.

HP Inverter technology

Inverter technology enables powerful yet quiet performance of Microwell heat pumps, while minimising the energy consumption. New Microwell models come exclusively with R32 gas.

Heat and cool with one device. Heat pump HP 1100 BLACK is designed for heating and cooling. The control is very simple. When you set your desired water temperature, the heat pump will automatically heat or cool to keep your desired temperature. HP 1100 BLACK Inverter provides with up to 6.5 kW cooling output.

Highly efficient ecological refrigerant

Reducing Global Warming & Ozone Layer Depletion by HP production The quantity of R32 refrigerant used is significantly lower as compared to the R410A refrigerant. Consequently, this results in decreasing the potential of global warming and minimal depletion of the ozone layer. That´s why Microwell developed the new generation of swimming pool heat pumps, working on the principles of R32 refrigerant with higher capacity.

High efficiency. Swimming pool heat pump is designed to compensate higher investment costs by very low operational costs compared to electric or gas heater. Microwell heat pumps are designed for a maximum efficiency reaching COP values up to 7. Efficiency of the heat pump is a ratio between power consumption (energy you pay) and actual heating or cooling output (energy you receive). With electric heater, the ratio is 1=1, i.e. what you consume and pay you get in the form of heat. Gas heaters may reach efficiency of 1.3. Heat pump’s COP of 7 means that you pay for 1kWh and you get 7kWh of energy. In cooling mode the heat pump provides with solid ratio of 4. Heat pump’s advantage is that it is independent from sun, day or night and weather. Currently the heat pump is the most efficient way of water conditioning in pools or hot tubs.

How is heat pump so efficient? Microwell HP 1100 BLACK heat pump is able to extract the heat/cold that is present in ambient environment and leveraged pass it into the pool water. If you take your refrigerator, it creates cold inside the fridge by releasing the heat from the back. Heat pump takes the heat (energy or calories) from ambient air and transforms it into the water. The surrounding air cools down in the process. When working in cooling mode, the excessive heat from water is passed into surrounding air. When heating, higher the ambient air temperature is, more free energy can the heat pump extract and thus reach higher efficiency. At favorable conditions you pay around 15% of heat, i.e. 85% of heat is free. Microwell heat pump is built on currently the most eco-friendly refrigerant R32.

Extraordinary INVERTER line. Microwell BLACK Inverter swimming pool heat pumps provide warm pool:

  • At lowest cost possible
  • In shortest possible time
  • With lowest noise possible

HP 1100 BLACK is equipped with Microwell unique microECONOMY+ feature offering the most economy circulation pump control. Microwell swimming pool heat pumps can be connected to existing water system (filtration) or it can have an individual circulation pump. A swimming pool heat pump needs continuous water flow to heat or cool. Pool heat pump tells the circulation pump when heat pump needs to heat or cool. The circulation is turned on and off according to this request. Microwell applies specially designed software that will sample the water and also put the whole system into sleep for the time when heating or cooling is not required. This saves precious energy and results in lower operational costs of the pool.

Titanium. Amount of titanium is very important to a swimming pool heat pump. The amount talks about the actual heat transfer area, i.e. power and efficiency of each heat pump. Microwell is proudly using 40% more titanium in heat pumps’ water exchangers. This maximizes the performance and efficiency COP&EER far ahead of others. HP 1100 uses 0.5m2 of titanium whereas others use less than 0.25m2.
