A Clean Heat Pump is an Efficient Heat Pump

A Clean Heat Pump is an Efficient Heat Pump

Swimming pool heat pumps are located outside in all seasons and this means that the units get dirty, one of the least considered aspects is the effect of dirt build-up on the heat evaporator.

Reduced air flow through the evaporator directly affects the heat pump’s ability to heat, reduced airflow means that less heat can be extracted from the ambient air, reducing the COP, this means the heat pump will take longer to heat your pool water and this in turn increases your running costs.

A dirty evaporator can reduce the efficiency of a heat pump by 10-15% per year

The evaporator fins are difficult to clean without damaging them and also the grid or mesh that covers them makes access difficult. A vacuum cleaner or air compressor cannot remove all the dirt between the lamellas (fins) and a pressure washer can deform the fins.

Gridsoap is a biodegradable spray that quickly, easily and effectively cleans and protects your heat pump evaporator. Simply spray on, leave for 10 mins and rinse off with your garden hose. No need for tools that could damage the fins and because Gridsoap is biodegradable it is not harmful to surrounding plants or wildlife.

Gridsoap will clean and protect your heat pump evaporator, maximising performance and efficiency and reducing the future build up of dirt. Gridsoap also helps to reduce the evaporator icing up as airflow is maintained.

Gridsoap is available now in 1 litre bottles with sprayer priced at £36.00 per bottle

10 Reasons to Buy a Robot Pool Cleaner

10 Reasons to Buy a Robot Pool Cleaner

One of the surprise best sellers this year has been our range of robot pool cleaners.

Offering fully automated cleaning of your pool, a robot cleaner will scan your pool, before scrubbing every surface including the floor, walls and waterline, while at the same time filtering the water to remove fine particles and larger debris leaving your pool and water sparkling clean.

Here are our top ten reasons to buy a robot pool cleaner:

1) A robot pool cleaner scrubs away dirt and algae that you may not even be able to see and regular use of the cleaner can prevent the growth of algae.

2) A robot pool cleaner ‘mixes’ the water in your pool as it passes through the cleaner, this mixing of the water dramatically reduces the amount of chemicals needed as absorption of the chemicals into your pool water is greatly improved.

3) Finer water filtration than that offered by suction-side or pressure cleaners, again helping to reduce the chemicals needed in your pool.

4) Robot cleaners are very energy efficient thanks to their low voltage motors.

5) Suction cleaners may require the installation of a more powerful pump – costing you more money to run even when the suction cleaner is not in use.

6) Robot cleaners cover the floor, walls and waterline, automatically, meaning that no manual scrubbing is required leaving you free to enjoy your pool.

7) Reduces the frequency that your pool filtration media needs to be changed, all dirt and debris collected by the robot pool cleaner is contained within the unit, after cleaning simply remove the filter basket and rinse

8) Pool cleaners are more affordable than ever, our range offers models to suit nearly all pool types and sizes at great price points.

9) No unsightly pool hoses, just a single cable that connects the cleaner and the mains transformer. When the cleaner has finished its cycle, simple remove from the pool and store until next needed (cleaners come with optional or included caddy for storage and transport depending on the model).

10) New features include Bluetooth control via your smartphone or tablet, a robot pool cleaner is the ultimate pool gadget, whether you want to plug and play or take full control there is a robot pool cleaner to suit you and your pool.

Swimming Pool Heat Pumps: Why honesty is our policy

Automated Environmental Systems Blog

There are many claims made about the heating abilities of swimming pool heat pumps and the savings that can be made to your energy bill.

While there is no doubt that an air source heat pump is the most cost effective and efficient way to heat a swimming pool in the UK, it is worth taking a moment to look at why choosing a heat pump based purely on the manufacturer’s specifications is not always the right choice.

Most manufacturers base the sizing and heating capacity of a heat pump on average air and water temperatures, there are usually two sets of figures, a lower figure based on an air temperature of around 15°C and a water temperature of 26°C, and a higher figure based on both air and water temperature of around 27°C.

The actual heating performance of a heat pump is referred to as C.O.P., the co-efficient of performance, put simply if a heat pump has a C.O.P. of 5.0 at air temperature of 15°C and water temperature of 26°C, then for every 1kW of energy consumed by the heat pump 5kW of energy is returned to your pool as heat.

Assuming that these average temperatures are maintained on a well insulated pool then a heat pump could be selected purely on the manufacturer’s specifications.

If for example your pool is 30m³ you could reasonably select a heat pump based purely on the manufacturer’s pool sizing of up to 30m³ – but you need to remember the average air and water temperatures would need to be met to achieve the stated heating capacity – the reality is that the British weather does not maintain these averages and therein lies the first problem.

The second problem that cannot easily be factored into a manufacturer’s calculations is heat loss, up to 80% of heat is lost through the surface of your pool – assuming that the rest of the pool is properly insulated – heat loss on above ground pools is further exaggerated as the sides of the pool are not usually insulated (unless a separate insulating frame has been constructed).

The third unknown is usage, the manufacturer cannot factor in how a pool is used, some pools may stay covered most of the day or week and only get occasional use, other pools could be uncovered all day and have high usage. You may only be a ‘fair weather’ swimmer and use your pool for a couple of months a year, you might open your pool in early spring and close it in late autumn or you may want to heat your pool all year round.

Any of these variables will have an impact on the ability of a heat pump to achieve the manufacturer’s stated heating capacity, restricting the temperature that can be achieved and reducing the period of use.

This is why we only ever take the manufacturer’s specifications as a guide, if you purchase a heat pump from us you can expect us to ask about the size and shape of your pool, whether the pool is insulated and covered when not in use, when and how you intend to use the pool and what your desired temperature is.

Talking of desired temperature, let’s take a moment to address one particular issue.

The speedometer on your car probably has a top speed that, in all likelihood, you would not achieve under normal driving conditions (even if it was legal to do so). In the same way while the temperature selector on most heat pumps will go up to 40°C, given our climate it would be unrealistic to expect that a heat pump on an outdoor pool in the UK could achieve this temperature, manufacturer guidelines are normally based on expectations of achieving a water temperature of 27-28°C.

Heating above this point is perfectly possible but the energy required to achieve each additional degree increases exponentially as does your heat loss, leading to a requirement for higher energy capacity (the compressor has to work much harder to create the differential of heat at higher temperatures, in the same way a kettle requires more much energy to actually boil water than to achieve 90°C). Therefore it maybe that you require a larger heat pump selection if you want a higher water temperature.

A heat pump has the potential to save you between 50% and 80% on traditional heating methods, such as oil or gas boilers, inline electric heaters etc., however the actual saving will depend on the weather, your desired temperature and the heat loss that needs to be overcome. The lower the ambient temperature the lower the heating capacity and the greater the heat loss.

It is for this reason that we usually look to the start and end of your pool season when recommending a heat pump, the points at which you are most likely to struggle to achieve your desired temperature. In most cases recommending a larger model provides additional heating capacity to overcome heat loss, increasing the achievable water temperature.

A common misconception is that putting a larger heat pump on your pool will cost you more to run, while it is true that a larger heat pump will consume more energy, it will run for a shorter time to achieve the same heat output as a smaller unit.

For example, if your pool required 100kW of energy to maintain your temperature at X (under ideal air temperatures). An 18kW heat pump with a power input of 2.51kW would run for 5.6 hours to heat your pool (100/18kW). This means you would consume approximately 14kW of energy (5.6 hrs x 2.51kW). A smaller 13kW heat pump with a power input of 1.86kW would run for 7.7 hours to heat your pool (100/13kW). This means you would consume approximately 14.3kW of energy (7.7 hrs x 1.86kW).

It is for this reason that more and more of our customers are choosing to over specify their heat pump, the higher initial purchase cost is more than offset by the flexibility provided by the additional heating capacity, if we don’t think a particular heat pump is right for your pool given the details you have provided, we will always explain why and make an alternative recommendation.

Nobody wants to make a purchase more than once, which is why honesty is always our policy.

CASE STUDY: Heating a large volume swimming pool using air source heat technology

CASE STUDY: Heating a large volume swimming pool using air source heat technology

The brief – to heat a large outdoor pool

Download your free copy of our case study (.pdf 3Mb)

We were asked to provide a solution for heating an extremely large 190,000L swimming pool with air source heat pump technology. The pool itself is located in Suffolk not far from our Brandon office so we were able to make site visits before, during and after installation.

The client wanted to heat the pool water to 29°C from April to October, this was particularly difficult given it was such a large outdoor swimming pool without an enclosure, the excessive heat loss at this water temperature presented the largest challenge.

The customer was extremely keen to use heat pump technology to ensure the low running cost of heating such a large swimming pool. Most air source heat pumps on the market are not capable of heating such large volumes of water, the limit is normally around 140,000L.


The solution – twin air source heat pumps

We proposed that given the space around the plant room we could use a twin heat pump solution, allowing us to increase the heat output capacity to overcome the heat loss and achieve the desired goal of heating this 190,000L swimming pool to 29°C.

The heat pump model we proposed was the 26kW Hydro-Pro 26T, the client had three phase electrics available on site.

Important considerations – key factors

Air flow – under normal conditions on a single heat pump set up, air flow is a critical consideration. With a twin heat pump installation it is even more critical that good air flow is achieved, if sited too close together each heat pump will lower the ambient temperature for the other heat pump, therefore additional space is required to ensure both heat pumps work efficiently.

Flow rate – for single heat pump installations flow rate control is very simple – one bypass kit will control the flow rate for the circuit. However with twin heat pumps the flow rate is much more difficult to control.


The final installation

Firstly we asked the customer to extend an existing concrete pad to accommodate the two new heat pumps. This would ensure sufficient airflow in the installation area, allowing the necessary distance required between the heat pumps to enable effective heating from both units.

However the spacing created an additional problem, water will always takes the course of least resistance, effectively meaning a higher flow rate to the nearest heat pump and reduced flow to the furthest heat pump.

We solved this by designing a pipework arrangement that was equal and symmetrical in length. This also means that if the flow rate changes the flow rate will increase or decrease equally across both heat pumps.

We also ensured that each heat pump had independent isolation valves, meaning a heat pump can be taken off the filtration circuit if required, without effecting the other heat pump.

With external pipework runs it is important to insulate pipework to reduce additional unwanted heat loss.


The result

The heat pumps were commissioned and started at 7pm on a Thursday evening, the pool water temperature was reading 16°C and the outside air temperature was 14°C. The outside air temperature on the following days stayed at 14-16°C, by Sunday afternoon the family were enjoying swimming in the pool with the water temperature at 28°C. The client is naturally really pleased with the result and has been swimming every day since.

Is the high water table creating havoc in your cellar or basement?

We get phone calls every day from people suffering with flooding in their cellars and basements caused by the high water table.

This particular problem is made more difficult because the water is only usually a couple of inches deep, enough to cause a problem for the property owner but not deep enough that a traditional pump float switch will activate.

Solutions may include manually activating a pump to remove the water or digging a pit in the floor, which very often is a concrete slab, and placing a submersible pump in the pit so the water is deep enough to activate a float switch.

In most cases the property owner just wants to install a pump with the minimum of fuss and cost and be able to leave the pump to work automatically as needed.

We now have the solution, our new EGO SE pump with adjustable start and stop levels has a minimum starting level of 15mm and will drain down to 1mm, meaning that you can leave the pump in automatic operation, safe in the knowledge that the water level need not get above a couple of centimetres before the pump activates and pumps the water away.

Setting the start and stop levels is achieved by simply removing the back cover and adjusting the levels of the start and stop probes, meaning the levels can be altered to suit any future application without changing the pump.

Another common problem is water in the bottom of lift shafts, again it is imperative that the water level is kept to a minimum before it is pumped away.

Made in Italy the EGO has been designed and constructed to provide performance and longevity of operation. These versatile pumps can be used for a multitude of drainage and pumping applications, but their special ability to start pumping at such a low level sets them apart from the crowd.

In stock now for £258 including FREE UK mainland delivery, the EGO 500 SE can be ordered here.
