NORSUP’S PX AND PV HEAT PUMPS FROM BOSTA

2020 has been an exceptional year so far for Bosta UK’s Norsup brand. More and more installers have been choosing the Norsup range over traditional brands in the market and this growth has been led by the boom in heat pump sales. Everything about the Norsup heat pump range has been focused on satisfying Bosta’s customers’ high expectations and there are a number of ways in how Bosta achieved that.

Firstly the design of the units is ultramodern, giving pool owners confidence in the quality and precise methods of manufacture. The large colour touch screen display is both functional and pleasing to the eye. Secondly, the Norsup unit offers unrivalled levels of performance. They are full inverter heat pumps which means that the compressor and fan motor fluctuate in frequency to work as efficiently as possible to achieve the perfect pool temperature. In peak months even the largest 35kW single phase unit only uses 0.5kW per hour of electricity to maintain temperature. The working parts slow down using a fraction of the power and in turn create almost inaudible sounds levels at just 22 decibels.

Finally, in addition to all their performance and aesthetic benefits, Bosta offer both the pool owner and the installer the reassurance and comfort of a full four years parts and labour warranty should anything go wrong. This period is also extended to ten years on the heat exchanger and compressor thanks to the top brand components used. With support like that, it’s clear why Norsup has become one of the leading choices of heat pumps for many pool companies across the UK.

COST EFFECTIVE HEATING WITH WATERCO’S ENERGY EFFICIENT INVERTER TECHNOLOGY

Compared to gas and electric heaters, models within the Electroheat ECO-V pool heat pump range from Waterco use just a fraction of the energy to generate the same amount of heat; and unlike solar heating, there is no reliance on the sun as the latent heat in the air is used. For every 1kW of electricity consumed, Electroheat ECO-V can produce up to 8kW of heat.

These inverter pool heat pumps utilise a variable speed compressor to regulate the pool water temperature automatically and independently.

This inverter technology is similar to a car’s engine in that it slows down and speeds up as needed to hold a selected desired temperature or speed. The desired temperature will be reached more quickly and maintained more efficiently and the inverter technology provides a more precise water temperature without the fluctuations and power wastage of fixed speed systems.

Inverter technology is significantly more energy efficient with energy savings of between 15 - 30% over fixed speed systems, and the speed control of the compressor and fan motor also means quieter operation.

Electroheat ECO-V inverter pool heat pumps feature automatic de-icing for situations where frost or ice may develop on the evaporator as part of normal operation. Common in cooler climates or winter months, when a build-up of ice is detected the heat pump shifts temporarily into cooling mode to reverse the flow of refrigerant through the evaporator coils. Hot refrigerant moves through the outside coils, melting ice and defrosting the system. When the defrost cycle is complete, the unit shifts back to heating mode.

THE HIGHLY EFFICIENT HEATWAVE SUPERQUIET® VARIABLE SPEED HEAT PUMP

US-based AquaCal AutoPilot, Inc., part of the larger HornerXpress Group, has just released what they claim is the world’s most efficient swimming pool heat pump. The HeatWave SuperQuiet® Variable Speed heat pump can reach a Coefficient of Performance (COP) of 10.5 or higher.

**The HeatWave SuperQuiet® Variable Speed heat pump can reach a Coefficient of Performance (COP) of 10.5 or higher**

AquaCal’s advanced variable speed heat pump technology will automatically adjust its speed, precisely matching the heating demand to maximise efficiency.

The reason pool owners buy heat pumps in the first place is for the efficiency, which greatly reduces the cost of heating a pool. This variable speed technology calculates the speed required to sustain the desired pool temperature in the runtime allotted. This approach can save up to 40% more in heating cost over a single speed heat pump.

Pool owners can expect to recoup the investment of this unit in energy savings in less than three years. Running at reduced speed lowers wear on the compressor, extending its service life. Even pair it with a variable speed pool pump to achieve the highest efficiency pool system possible.

Also released is the PoolSync™ Wi-Fi Controller. This Wi-Fi antenna connects AquaCal® heat pumps to the internet and allows them to be controlled through the PoolSync™ App on a smartphone. Heat pump owners can change the mode of the unit from heat to cool to autotemp, when applicable, and adjust the temperature setting. It also allows owners to set up schedules of when to turn the unit on and off and at what temperature. The PoolSync™ Wi-Fi Controller and app work with all AquaCal® heat pumps manufactured with the advanced HP9 controller, which was released in early 2019.

VERTICAL INVERTECH MODEL JOINS SCP’S HEAT PUMP OFFERING

SCP UK offer a number of heat pump solutions and one of their popular lines is the InverTech series from Garden Pac. Joining this tried and tested range of inverter heat pumps for 2020 is the new Vertical Invertech Turbo which is available in three models – meaning pools with volumes of water from 35m³ to 95m³ are all covered.

During standard use, each heat pump runs at the capacity needed to maintain heat levels and keep running costs as low as possible.

However, as the name suggests, each Vertical Invertech Turbo model has a unique booster function meaning heating performance can be 20% higher than the label capacity. By pressing the ‘boost’ button, the heat pump can run at full capacity which allows for the quick heating of any pool. This is possible thanks to larger compressors and evaporators.

MODERN DESIGN OF ZODIAC HEAT PUMP MODELS HELP THEM TO BLEND IN

The Zodiac Z400iQ ups the game on the design of air source heat pumps, with its sleek lines and two colour options, the Z400 iQ disappears elegantly into any pool’s surroundings.

The traditional horizontal air-discharge of other heat pumps, require several metres of space in front of them but the Z400iQ, with its vertical air outlet, reduces this free area footprint by 70%. This discreet machine, fits around most pools, even in confined spaces the Z400iQ knows how to go unnoticed, halving the noise with its silence mode, which reduces the fan speed at the touch of a button.

Add to this the smartphone capability allowing users to set temperatures remotely and consult the Z400iQ’s different modes of operation and you truly have an air source heat pump which ticks all the boxes of the modern pool owner.

The ever-more popular Zodiac ZS500 range of heat pumps is continuing to please pool customers across the land too. The elegant, modern, clean shape of the ZS500 allows it to be placed into the garden and not look like the blocky chunk of steel which this sector often seems to be burdened with. The vertically mounted, top venting fan allows for the machine’s small footprint (610x670mm and 980mm high) to make the most of its clean lines. Centre front offers a large easy to read digital display with the set point and current running temperature shown. The unit is ideally placed into tight corners where a conventional heat pump would struggle to perform, as the ZS500 only requires a 500mm air gap around its base, its cold discharge air is blown into the sky where the 5m clearance is usually not a problem.

Add to this an inverter driven fan and compressor and you get a machine that doesn’t wake the neighbours when it comes on in the evening, in fact it is so quiet it’s almost easy to forget that it is even there.

HEATSEEKER® FROM PLASTICA – AN ENVIRONMENTALLY FRIENDLY SOLUTION

Inverter heat pumps have quickly become more widespread as customers become aware of fuel price increases and they prefer more cost effective and energy efficient ways to heat their swimming pools. The new Plastica HeatSeeker® Inverter Heat Pump can consume less than 12% of the electricity of conventional electric pool heaters maintaining the same heating capacity.

The new HeatSeeker® range of Inverter Heat Pumps produce a COP of an average five times for every one kW of electricity consumed, running with an air temperature of only 15°C. If the air temperature available increases, the efficiency can be over eight times the supply power.

Plastica’s new range comes with new inverter technology that not only gives a low start-up current eliminating any power surge but also the variable fan speeds allow it to keep the pool water at an optimum temperature while maximising efficiency. Another benefits of this is a much quieter operating noise level than any previous ranges, making conforming to environmental legislation no problem.

The integral variable fan draws air across an evaporator, heat from the airflow is captured by the refrigerant flowing through the body of the evaporator. This refrigerant is of an R32 type that is acceptable under all new regulations. Having extracted the heat from the air, the refrigerant is condensed and its heat then transferred to the passing pool water via the titanium heat exchanger.

Plastic’s comprehensive range of HeatSeeker ® Inverter Heat Pumps will cover the full heating requirements of pools from 25m³ up to 85m³ of water volume and will work efficiently for the whole season.
