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.

No preparation for winter whatsoever

One of key advantages of split heat pumps is their easy maintenance. Unlike monoblock heat pumps, that require winterizing, i.e. complete water drainage from their water exchangers in winter months; split heat pump does not require any winterizing or any preparation for winter whatsoever. This is simply because water exchanger of a split heat pump is typically installed in a pool plant room, where air temperature typically does not fall under 0°C.

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 2300 SPLIT INVENTOR is a powerful heat pump suited for pools up to 80m3 in volume.

HP 2300 SPLIT INVENTOR can provide up to 27.2kW of heating at typical seaside conditions of air temperature 26°C, water temperature 26°C and air humidity 80%. At typical inland conditions of air temperature 26°C, water temperature 26°C and air humidity 63% the heat pump provides with 23kW. At dry conditions with humidity 35% the pump reaches above 20.9kW heating output.

Self-cleaning color is a recent innovation by Microwell. Main purpose is to ensure fresh and new look of the heat pump after years of working in exterior.

The final finish is a special paint made on the basis of years of experience and the latest knowledge in the field of nanotechnology. Color has nanopore structure that creates a microscopic film on the surface of the heat pump. Nanopores are too small for a dust or dirt to be caught up at. Despite that should any dirt be gathered on the cover, it will be washed away with the first rain.

Self-cleaning color is a true innovation that brings value for the customer.

Heat and cool with one device. Heat pump HP 2300 SPLITINVENTOR 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 2300 SPLIT INVENTOR provides with up to 20.1 kW cooling output.

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 2300 SPLIT INVENTOR 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 R410A.

Compact / Split. Microwell heat pumps are designed as compact or split machines. A Compact unit (HP 2300 COMPACT INVENTOR) is a one-box device that requires water and electrical connection. Its advantage is simple and quick installation. Disadvantage is that it is typically installed few meters from pool which may lead into visual or noise disturbance. A split heat pump (HP 2300 SPLIT INVENTOR) is just like a split air conditioner or ceiling cassette air conditioner. The idea is to have warm or cool water at no visual or noise disturbance. Split heat pump can be installed as far as 30m away from pool. Typically the unit is hidden by the house, on the roof or in the backyard behind trees. This is also very safe for children.

Microwell heat pumps are sold throughout entire network of professional resellers with strong technical support. The distributors will gladly handle any of your pre and post sales technical matter.

HP 2300 SPLIT INVENTOR 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 2300 SPLIT INVENTOR 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 2300 SPLIT INVENTOR 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 2300 COMPACT uses 1.13m2 of titanium whereas others use less than 0.25m2.

Microwell heat pump is only 1250mm high and 360mm deep. This saves space and does not protrude in the garden.

Microwell HP 2300 SPLIT INVENTOR consumes on average 3.59kW while heating to 23kW (air temperature 26°C, water temperature 26°C, relative humidity 63%) at 38dB(A) only confirms how well designed and manufactured the pumps are.

Control. The heat pump is controlled by built-in digital panel. This panel can be installed anyway in pool area, technical room or inside the house for your convenience.

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