GoldFin: Your Timeless Guardian

You ever wondered why heat pumps look blue or goldish (yellow) from the back? This the protection layers of the aluminum fins of the air exchanger. 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.

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.

Operating on the thermodynamic principle, which is considered to be one of the most energy efficient systems for water heating or water cooling, Microwell heat pumps are capable of extracting ambient air from any environment ensuring maximum performance with an efficiency that remains unsurpassed on the market.

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

HP 1400 Green is a powerful heat pump suited for pools up to 55m3 in volume.

HP 1400 Green can provide up to 12.3 kW of heating at typical seaside conditions of air temperature 27°C, water temperature 27°C and air humidity 80%.

Heat and cool with one device. Heat pump HP 1400 Green 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 1400 Green provides with up to 6.2 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 1400 Green 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.

Microwell swimming pool heat pumps provide warm pool:

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

HP 1400 Green 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. HP 1400 Green 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.

Full year heating. HP 1400 Green is also designed for a full year heating, particularly winter time. Typical winter can experience air temperatures -15°C. Heat pump thus needs to be protected against possible frost damage and equipped with systems that will keep the heat pump’s performance at desired level.

Long livelihood. Microwell swimming pool heat pumps are designed for 15+ years livelihood. The product requires minimal maintenance. You only need to ensure cleanness of air exchanger from leaves, dust and other particles.

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 1400 Green uses 0.6m2 of titanium whereas others use less than 0.25m2.

Dimensions LxWxH (mm): 1000 x 385 x 665

Microwell HP 1400 Green consumes on average 1.8 kW while heating to 12.3 kW (air temperature 27°C, water temperature 27°C, relative humidity 80%) at 32dB(A) only confirms how well designed and manufactured the pumps are.

Extra features. Microwell is continuously focusing on customers’ demands and wishes. Each heat pump is equipped with special features unique about Microwell heat pumps.

antiVIBRATION+ offering special set of mounting silent blocks eliminating excessive vibration and noise.
