How To Set Up Swimming Pool Pump
Pool Heat Pump Installation Tips
This article outlines our pool heat pump installation tips for the all-time practice way to install your swimming pool heat pump.
Installing your pool heat pump is a adequately simple task and can exist completed either by the pool owner, a local engineer or past one of our experienced installation engineers. The manufacturer'southward recommendations should nevertheless always be followed in lodge not to invalidate the warranty, or to prevent your rut pump from working properly.
If you would like us to install the estrus pump for you, please contact united states of america for an installation quote.
Here are some tips if y'all make up one's mind to install a pool heat pump yourself:-
The heat pump requires:-
1. A Suitable Location
Cull a location for your heat pump where it can become a expert menstruation of air. Optimum efficiency of the heat pump relies on good air flow.
Where possible the rut pump should e'er be installed outdoors so it tin can receive a practiced supply of fresh air to operate and extract the heat from.
Minimum clearances for horizontal fan heat pumps shown to a higher place
Minimum clearances for vertical fan estrus pumps shown above
Make sure that the air existence expelled by the fan volition not hit any obstacles and could exist recirculated back into the rut pump.
Puddle heat pumps, come up in two main formats – vertical fan and horizontal fan models. Vertical fan models will depict air in at the sides of the rut pump and blow cooler air upwards out of the top of the unit of measurement. Yous should ensure that in that location are no obstructions above the heat pump that could cause the expelled air to recirculate back into the unit of measurement as this will reduce its efficiency, eg low hanging trees or roofs etc.
Similarly horizontal fan models will depict air in at the back of the unit and blow out colder air from the front of the heat pump. More than space is ameliorate, just equally a minimum, you should allow 300mm behind the estrus pump and 2 metres in front of it. Again, the expelled air should be able to accident away without striking obstructions eg hedges, fences etc which could cause the air to re-broadcast.
Vertical fan models should accept at to the lowest degree 2 feet (600mm) clearance effectually the sides and no obstructions above every bit per the diagram below.
Minimum Clearance Requirements
Duratech Blazon Estrus Pump Required Clearances
Pool heat pumps should wherever possible exist installed outdoors in order to take a good supply of fresh air. Even so some can be installed inside a pump firm – see the section beneath.
Endeavor to locate the heat pump shut to the pool pump to minimise the friction in the pipes. If your pipe run is too long, yous may have an insufficient water flow rate through the heat pump and may need to upgrade your pool pump or utilize larger bore pipes to and from the oestrus pump to reduce friction in the pipes and maintain a good water menstruation charge per unit.
Most oestrus pumps state the nominal water period required on their specification charts. If the h2o flow through the heat pump is too low, then the heat pump may overheat and the prophylactic mechanism will turn the unit off.
Not Like This – Hall of Shame !
Some examples of incorrect swimming pool heat pump installations.
 |  | |
| Bereft Clearances on three-sides of heat pump | Insufficient clearances for air-period | |
 |  | |
| Insufficient clearance at front – should be at least 2.5m. Rut pump is wrong way round ! | Bereft clearance – Heat pump blowing onto shed | |
 |  | |
| Insufficient clearance – should exist at least 2.5m at front and 300mm at dorsum | Oestrus pump installed nether decking. Chance of air recirculation and insufficient air flow | |
 |  | |
| Calorex heat pump installed inside a shed only the incorrect way round ! Should accident to the outside, not inside the shed. Also fan blowing onto an obstruction | Heat pump is installed the incorrect mode round, is blowing onto the wall ! Information technology should have a minimum of 2.5m clearance in front end of the fan. |
Heat pump enclosed in wooden box, and so no airflow !
To see examples of heat pumps installed correctly, please see our Photo Gallery
two. H2o Flow Charge per unit
Almost of our pool heat pumps land the required water flow charge per unit on their specifications table. If the water menses rate is likewise low, then the water in the estrus pump will overheat and the estrus pump will switch off.
Check the water menstruum rate from your pool pump and through your filter to ensure that it is high plenty for your pool heat pump.
Note that there is a maximum possible period through each size of puddle pipe regardless of the power of your pump. For larger heat pumps it may non be possible to attain sufficient water menstruation through small pipes (eg 1.five″ pipes). Please contact us for advice on this.
We sell water catamenia meters that volition evidence you the menstruation rate through your pipes.
See our "Accessories" section
You should also regularly backwash your pool filter to ensure that the water catamenia charge per unit remains at an acceptable level.
3. Base
The base for the heat pump should be level and audio. You can use either a physical base, paving slabs laid on sand or timber decking.
The vibration from the heat pump will be fairly minimal and will not disturb the paving slabs.
The heat pump can be installed above or beneath h2o level. The only proviso is that the pool circulation pump is powerful plenty to deliver the water flow rate that the heat pump needs to operate.
Nosotros too sell mounting feet and lightweight slabs to mountain the heat pump on. These assist to raise the heat pump off the ground and besides reduce racket and vibration
While the heat pump is operating, information technology is normal for condensation water to drip from it – peculiarly in humid conditions. Y'all should consider the condensate water that volition come from the unit in the base of operations design every bit the amount of water can be considerable and crusade a pool of h2o to form. For example if the unit of measurement is mounted on timber decking, holes tin be made in the decking to permit the condensate water to drain away and not cause rotting to the timber.
Some heat pumps take a h2o outlet tube that will aqueduct the condensate water abroad, or a piece of hose can be fastened to it to divert the water to a specific location.
Some customers mistakenly think that the heat pump has a leak when in fact the water coming from the estrus pump is normal condensation
four. Electrical Supply
Earlier purchasing a puddle heat pump, yous should check the running electric current and top current stated on the listing for your desired model.
Ensure that your electrical supply is adequate to back up the running and startup currents for the unit.
Information technology is normally recommended to run a dedicated cable back to your electrical consumer unit for the heat pump and install a defended billow for the heat pump.
Near oestrus pumps will have a college electric current need when they kickoff. This only lasts for a millisecond or so while the compressor starts and the electric current and then reverts to the normal running current for the unit.
The size of circuit billow required is normally stated on the listing for each oestrus pump and is normally slightly larger than the startup current.
You would unremarkably utilize a type "D" circuit breaker (fuse) with your estrus pump. The type "D" circuit billow allows for the higher current at startup (equally the compressor starts) without tripping the billow.
If you lot have a very "sensitive" electrical supply, and so some heat pumps take an optional (or built in) "soft-beginning" option. The soft-start choice "eases" in the startup current up to the running current to avoid a ability spike on startup.
The soft-first kit/choice is normally merely required for installations using a large single phase heat pump (eg 30kw) with a limited or sensitive electrical supply. In extreme situations, the business firm lights may flicker or the circuit breaker trips when the heat pump starts upward. The soft-starting time kit helps to foreclose this.
The soft-start option is not normally required in the Great britain, or on pocket-size heat pumps or on 3-stage oestrus pumps. Delight contact us for further information.
We sell a third-political party soft start module that tin can exist added to virtually any heat pump. This is listed nether our "Accessories" section
Armoured cablevision is normally used to supply the heat pump. This is to prevent the cable from being accidentally damaged (eg by earthworks through information technology with a spade)
The size (thickness) of the cable required depends on the length of cable used. A longer cable run volition require a thicker cablevision due to the increased resistance of the long cable.
The armoured cable should exist run to a rotary isolator switch which should be located within 1-meter of the heat pump to allow the ability to be hands killed to the rut pump
The electric piece of work should be completed by a qualified electrician who can calculate the cable size required.
The estrus pump must likewise exist properly earthed.
As the heat pump is outdoors, the electrical excursion should too be protected by an RCD
Almost properties have a single-phase electrical supply. iii-phase electrical supply is ordinarily only plant on larger backdrop or on commercial installations. If you lot are not sure, y'all probably accept a unmarried phase electric supply, but inquire your electrician to confirm this for you.
Single phase supplies operate at around 230-240v in the U.k. and have one alive wire, neutral and globe and are the most common blazon of power in domestic properties.
Larger backdrop may accept a three-phase power supply. This typically operates effectually 380-415v and uses 3 live wires, a neutral and earth wires.
Note that most three-phase installations are 380v-415v, however in France it is possible to discover both 380v-415v and some older 220v 3-stage supplies, so please check which type you have earlier ordering.
All of our oestrus pumps are manufactured to work with 50hz electrical supplies (which are used throughout Europe)
Note that in the The states, they use a 60hz electrical supply. USA specification heat pumps will not piece of work in the United kingdom of great britain and northern ireland or Europe. All of our rut pumps are made to apply a 50hz electrical supply.
We can supply an electrical connexion box with a congenital in timer for your pool pump – see our "Accessories" section
The electrical command boxes can be custom designed to your requirements. Please contact us for a quote.
five. Plumbing
It is easy to add together a heat pump to an existing pool pipework system.
First check to come across what size of pipes you accept.
In the Britain, these are normally 1.5″ or 2″ pipes. In Europe, 50mm is more mutual. Check the writing stamped on your existing pipes and elbows to see which size you accept. Do non just measure out the external diameter of the pipes or fittings as this is often different to the size required and you may accidentally society the wrong size pipe and pipe fittings !
eg 1.five″ pool pipage measures approx 1.9″ external diameter (the one.5″ refers to the internal bore of the pipes for purple sizes and the external diameter for metric sizes)
One time you know the existing pipe size that you take, you will know what size connectors and elbows you will demand.
In the Great britain 1.5″ pipes are the nigh common and 50mm in Europe.
Please run across our Accessories section for a catalogue of pipage fittings.
If y'all accept an existing pool heater eg gas or oil banality, then if it still works ok, we recommend that you lot leave it in place and put the heat pump in line with the existing banality.
This will allow you to run both the heat pump and banality if required for a rapid pool oestrus up. The former heater can as well help to supplement the heat from your heat pump in very common cold weather to assist extend the swimming season.
Where possible the water should run through the heat pump first and and then the existing heater then that the heat pump does about of the heating work. The thermostat on the existing heater (eg gas boiler) can exist prepare lower than the heat pump so that the existing heater will just operate if required.
There are simply ii pipes to the heat pump – a "flow" and a "return" piping.
Nosotros recommend that you lot install a "bypass" arrangement with your heat pump
The bypass is a series of 3-valves. These allow you to isolate the estrus pump to prevent h2o flowing through it.
A bypass can too permit the water period rate to be adjusted to reach the optimum performance for the heat pump. We are happy to advise on how to adjust the catamenia charge per unit appropriately depending on the make and model of heat pump used.
Generally, you should aim for a difference between water in and water out temperatures of around 1-2 degrees
Nosotros sell featherbed kits under our Accessories section
This is required in winter when you need to drain all water from the heat pump to forestall impairment by freezing, however you may have a frost stat on your pool pump and may wish to continue to circulate the water circular your pool pipes.
The bypass setup also allows yous to adapt the h2o period rate passing though our oestrus pump. By slghtly opening the bypass valve, you can reduce the water menses through the heat pump.
You must not allow water to freeze inside the heat pump during winter as this can scissure the heat exchanger and frost/freezing harm is mostly not covered by the manufacturer's warranty. We sell a range of winter covers for pool estrus pumps to protect your unit of measurement – see our Accessories section
The pipes to and from the heat pump tin can be insulated to help reduce heat loss.
The heat pump is normally installed every bit the last item in the water period before the water returns to the pool, ie after the filter.
The merely exception to this is if you accept a chlorination unit in which case this should exist the last item before the water returns to the pool so that concentrated chlorine does not become through the heat pump as this could crusade premature corrosion to the heat exchanger.
The heat pump can be installed aslope whatever existing heater that you have (eg gas heater). This allows you to employ the gas heater as well as the heat pump if required either to rapidly heat upwards the pool or if the air temperature is also common cold to run the estrus pump efficiently eg at the and of the swimming flavor.
Try to take the h2o going through the heat pump outset and and then the gas/oil heater and so that the heat pump does most of the heating work and the existing boiler only needs to "height-up" the temperature
6. Multiple Estrus Pumps
For large pools, information technology is possible to run two heat pumps together
or even larger pools can use four rut pumps
Multiple heat pumps can be plumbed in series or in parallel. Please contact the states for advice on the all-time method to use for your state of affairs.
7. Indoor Heat Pump Installations
Where possible a heat pump should always be installed outdoors equally they demand a abiding supply of fresh air to operate and extract the heat from. However it is possible to install some models within the establish room. For vertical fan models, ducting can be constructed to to vent the expelled air out through the wall of the building.
For horizontal fan models, they can be placed up against the wall and a hole cutting through the wall in line with the fan to allow the expelled air to escape to the outside.
Recirculation of the expelled air back into the oestrus pump must exist avoided.
For indoor installations, it is as well necessary to permit air to enter the pump house. A vented door or grille should be installed at the contrary side of the pump house which is sufficiently big to let fresh air to enter the room at the same rate that it is leaving the room.
For indoor pools, placing the heat pump within the pool building tin can help to dehumidify the air by drawing fresh air into the pool room and using the rut pump to expel the humid air.
The disadvantage of this organisation is that the air temperature inside the pool room volition soon be reduced to the same as the outside air temperature. For indoor pools, this may not be desirable and some sort of air heating may and so be required negating the do good of locating the heat pump indoors.
8. Indoor Pools
Indoor pools have different requirements to outdoor pools, the principal deviation being the need to dehumidify the moist air and also to heat the air in winter.
Unremarkably for indoor pools, the air temperature should be i degree warmer than the pool h2o. eg pool h2o = 28c, air temp = 29c.
For indoor pools, we do sell an all in one unit from Heatstar or Calorex that provides air heating, air dehumidification, fresh air inlet and pool water heating. Please contact united states of america for details.
At that place are ii main options for indoor pools:-
- Pool rut pump and separate free-standing or wall mounted dehumidifiers. The dehumidifiers can have built in electric heaters to warm the pool room air in winter.
- All in one unit providing air heating, air dehumidification, fresh air inlet and puddle water heating. These units demand ducting to blow the dehimidified air over any glass windows to prevent condensation from forming.
We can also blueprint a arrangement which is powered by an domestic blazon air source heat pump, feeding a buffer tank
Nosotros offer an indoor pool design service to help select and specify all of the equipment for indoor pools
See our Indoor Pools page for more information
9. Heat Pumps for Hot Tubs and Swim Spas
Our estrus pumps can also be installed on hot tubs and swim spas.
Using a estrus pump will normally requite greatly reduced running costs compared to an electric heater and the employ of heat pump on spas and hot tubs is condign increasingly popular.
The desired water temperature can be gear up to a maximum of +40c
The estrus pump is just plumbed into the existing spa circuit
We recommend that the existing electric heater is retained equally a fill-in heater to the heat pump for extremely cold (sub-zilch) air temperatures
Ideally the water should menstruum through the heat pump starting time and then the electric heater second.
Please contact the states if you would similar any advice on incorporating a estrus pump onto a hot tub or swim spa.
