Pool Heat Pump Installation Tips
This commodity outlines our puddle heat pump installation tips for the best practice way to install your swimming puddle heat pump.
Installing your pool heat pump is a fairly elementary job and tin can be completed either past the puddle owner, a local engineer or by one of our experienced installation engineers. The manufacturer's recommendations should however always be followed in club not to invalidate the warranty, or to forbid your heat pump from working properly.
If you would similar usa to install the heat pump for y'all, please contact united states for an installation quote.
Hither are some tips if you determine to install a pool heat pump yourself:-
The heat pump requires:-
1. A Suitable Location
Choose a location for your heat pump where it can get a good catamenia of air. Optimum efficiency of the estrus pump relies on good air menses.
Where possible the heat pump should always exist installed outdoors so information technology tin can receive a expert supply of fresh air to operate and extract the rut from.
Minimum clearances for horizontal fan heat pumps shown to a higher place
Minimum clearances for vertical fan heat pumps shown in a higher place
Make sure that the air being expelled by the fan will not hit any obstacles and could exist recirculated back into the heat pump.
Pool estrus pumps, come up in 2 main formats – vertical fan and horizontal fan models. Vertical fan models will draw air in at the sides of the heat pump and blow cooler air up out of the top of the unit. Yous should ensure that at that place are no obstructions above the heat pump that could crusade the expelled air to recirculate dorsum into the unit as this will reduce its efficiency, eg low hanging trees or roofs etc.
Similarly horizontal fan models volition draw air in at the back of the unit and blow out colder air from the forepart of the oestrus pump. More than space is better, but every bit a minimum, you should allow 300mm behind the heat pump and 2 metres in forepart of it. Over again, the expelled air should be able to blow away without hitting obstructions eg hedges, fences etc which could cause the air to re-circulate.
Vertical fan models should take at least two feet (600mm) clearance around the sides and no obstructions above as per the diagram below.
Minimum Clearance Requirements
Duratech Type Heat Pump Required Clearances
Pool oestrus pumps should wherever possible be installed outdoors in order to have a adept supply of fresh air. Nonetheless some tin can exist installed inside a pump house – encounter the section below.
Effort to locate the oestrus pump shut to the pool pump to minimise the friction in the pipes. If your pipe run is too long, you lot may have an insufficient water flow rate through the oestrus pump and may need to upgrade your puddle pump or utilise larger diameter pipes to and from the heat pump to reduce friction in the pipes and maintain a good water menstruum charge per unit.
Almost heat pumps land the nominal water flow required on their specification charts. If the water menstruum through the heat pump is besides low, and then the heat pump may overheat and the safety mechanism will turn the unit off.
Not Similar This – Hall of Shame !
Some examples of wrong swimming pool heat pump installations.
 |  | |
| Bereft Clearances on 3-sides of heat pump | Insufficient clearances for air-period | |
 |  | |
| Insufficient clearance at front – should be at to the lowest degree 2.5m. Heat pump is incorrect way circular ! | Bereft clearance – Rut pump bravado onto shed | |
 |  | |
| Insufficient clearance – should exist at least ii.5m at front and 300mm at back | Heat pump installed under decking. Chance of air recirculation and insufficient air flow | |
 |  | |
| Calorex rut pump installed within a shed only the incorrect mode round ! Should accident to the outside, not inside the shed. Also fan blowing onto an obstacle | Heat pump is installed the wrong way round, is blowing onto the wall ! It should accept a minimum of two.5m clearance in front of the fan. |
Heat pump enclosed in wooden box, so no airflow !

ii. H2o Flow Charge per unit
Most of our pool estrus pumps state the required water flow charge per unit on their specifications table. If the water flow rate is besides low, then the water in the heat pump volition overheat and the heat pump will switch off.
Check the water menstruation rate from your pool pump and through your filter to ensure that it is high enough for your puddle heat pump.
Note that there is a maximum possible period through each size of pool pipe regardless of the power of your pump. For larger oestrus pumps it may non exist possible to achieve sufficient water flow through small-scale pipes (eg i.5″ pipes). Please contact u.s.a. for advice on this.
We sell h2o flow meters that will testify you the flow rate through your pipes.
See our "Accessories" section
You should also regularly aftermath your pool filter to ensure that the water flow rate remains at an adequate level.
three. Base
The base of operations for the heat pump should exist level and sound. You can use either a concrete base of operations, paving slabs laid on sand or timber decking.
The vibration from the heat pump volition be fairly minimal and volition not disturb the paving slabs.
The heat pump can be installed higher up or below water level. The simply proviso is that the pool circulation pump is powerful enough to deliver the h2o period charge per unit that the heat pump needs to operate.
We besides sell mounting feet and lightweight slabs to mountain the heat pump on. These assist to raise the heat pump off the ground and also reduce racket and vibration
While the heat pump is operating, it is normal for condensation h2o to drip from it – particularly in boiling weather condition. You should consider the condensate water that will come from the unit of measurement in the base design every bit the amount of h2o tin be considerable and cause a puddle of water to course. For instance if the unit is mounted on timber decking, holes tin be made in the decking to allow the condensate water to drain away and not cause rotting to the timber.
Some heat pumps have a water outlet tube that volition channel the condensate water away, or a piece of hose tin can be attached to information technology to divert the water to a specific location.
Some customers mistakenly recall that the heat pump has a leak when in fact the water coming from the heat pump is normal condensation
4. Electric Supply
Before purchasing a pool heat pump, you lot should check the running current and peak electric current stated on the listing for your desired model.
Ensure that your electric supply is acceptable to support the running and startup currents for the unit.
It is unremarkably recommended to run a dedicated cable dorsum to your electric consumer unit of measurement for the oestrus pump and install a defended billow for the oestrus pump.
About rut pumps will accept a higher electric current demand when they start. This only lasts for a millisecond or so while the compressor starts and the current then reverts to the normal running current for the unit.
The size of circuit breaker required is normally stated on the listing for each heat pump and is normally slightly larger than the startup current.
You lot would normally use a blazon "D" circuit breaker (fuse) with your heat pump. The type "D" circuit breaker allows for the higher current at startup (every bit the compressor starts) without tripping the breaker.
If you have a very "sensitive" electrical supply, then some heat pumps have an optional (or built in) "soft-start" option. The soft-start pick "eases" in the startup current up to the running current to avoid a ability spike on startup.
The soft-kickoff kit/pick is normally simply required for installations using a big single stage heat pump (eg 30kw) with a limited or sensitive electrical supply. In extreme situations, the firm lights may flicker or the circuit breaker trips when the oestrus pump starts upwards. The soft-start kit helps to prevent this.
The soft-start option is not normally required in the Uk, or on small estrus pumps or on 3-phase heat pumps. Please contact us for further information.
We sell a third-political party soft start module that can be added to well-nigh whatsoever heat pump. This is listed under our "Accessories" section
Armoured cable is usually used to supply the heat pump. This is to prevent the cable from beingness accidentally damaged (eg past digging 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 crave a thicker cable due to the increased resistance of the long cable.
The armoured cable should be run to a rotary isolator switch which should be located within 1-meter of the heat pump to let the power to be easily killed to the heat pump
The electric piece of work should be completed by a qualified electrician who tin summate the cablevision size required.
The rut pump must besides exist properly earthed.
As the oestrus pump is outdoors, the electric circuit should also exist protected by an RCD
About properties have a single-stage electrical supply. 3-stage electrical supply is commonly only establish on larger properties or on commercial installations. If yous are not sure, you lot probably have a single phase electric supply, but ask your electrician to ostend this for you.
Single stage supplies operate at around 230-240v in the U.k. and have 1 live wire, neutral and earth and are the most common type of power in domestic properties.
Larger properties may have a three-phase power supply. This typically operates around 380-415v and uses three live wires, a neutral and globe wires.
Annotation that virtually 3-phase installations are 380v-415v, nonetheless in France it is possible to find both 380v-415v and some older 220v iii-stage supplies, so please cheque which type you lot have earlier ordering.
All of our heat pumps are manufactured to work with 50hz electrical supplies (which are used throughout Europe)
Note that in the USA, they utilize a 60hz electrical supply. United states of america specification oestrus pumps volition not piece of work in the U.k. or Europe. All of our oestrus pumps are fabricated to utilise a 50hz electrical supply.
We tin supply an electrical connection box with a congenital in timer for your pool pump – meet our "Accessories" section
The electrical control boxes can be custom designed to your requirements. Delight contact us for a quote.
v. Plumbing
It is piece of cake to add a oestrus pump to an existing pool pipework system.
Starting time cheque to see what size of pipes you have.
In the United kingdom of great britain and northern ireland, these are normally i.5″ or 2″ pipes. In Europe, 50mm is more common. Check the writing stamped on your existing pipes and elbows to see which size y'all have. Practise non just mensurate the external bore of the pipes or fittings as this is often different to the size required and you may accidentally order the incorrect size pipe and pipage fittings !
eg i.5″ pool piping measures approx ane.nine″ external bore (the i.5″ refers to the internal diameter of the pipes for imperial sizes and the external diameter for metric sizes)
Once you lot know the existing piping size that y'all accept, you will know what size connectors and elbows yous will demand.
In the Britain ane.5″ pipes are the most common and 50mm in Europe.
Please see our Accessories department for a catalogue of pipe fittings.
If you lot take an existing pool heater eg gas or oil boiler, then if it withal works ok, nosotros recommend that you go out it in place and put the heat pump in line with the existing banality.
This will allow y'all to run both the heat pump and boiler if required for a rapid puddle heat up. The old heater tin can also help to supplement the estrus from your heat pump in very cold conditions to help extend the swimming flavor.
Where possible the h2o should run through the heat pump first and then the existing heater then that the estrus pump does most of the heating piece of work. The thermostat on the existing heater (eg gas boiler) tin be set lower than the heat pump so that the existing heater will only operate if required.
There are only two pipes to the oestrus pump – a "menstruum" and a "return" pipe.
We recommend that y'all install a "bypass" arrangement with your estrus pump
The featherbed is a series of 3-valves. These let you to isolate the heat pump to preclude h2o flowing through it.
A bypass tin also allow the water menstruum rate to be adjusted to achieve the optimum functioning for the heat pump. We are happy to advise on how to adjust the flow rate accordingly depending on the make and model of rut pump used.
Generally, you should aim for a deviation betwixt water in and h2o out temperatures of around i-two degrees
We sell bypass kits under our Accessories department
This is required in winter when you need to drain all water from the heat pump to foreclose damage past freezing, however you may have a frost stat on your pool pump and may wish to proceed to circulate the water round your pool pipes.
The featherbed setup as well allows yous to arrange the water flow rate passing though our rut pump. By slghtly opening the bypass valve, you lot can reduce the water flow through the heat pump.
You lot must non let h2o to freeze within the heat pump during wintertime equally this can crack the heat exchanger and frost/freezing damage is generally not covered by the manufacturer's warranty. We sell a range of wintertime covers for pool heat pumps to protect your unit – see our Accessories section
The pipes to and from the rut pump tin be insulated to help reduce estrus loss.
The heat pump is normally installed as the last item in the water catamenia before the water returns to the pool, ie after the filter.
The only exception to this is if yous have a chlorination unit in which case this should be the last item before the h2o returns to the pool and then that full-bodied chlorine does non go through the oestrus pump every bit this could cause premature corrosion to the rut exchanger.
The estrus pump tin can exist installed alongside any existing heater that y'all have (eg gas heater). This allows you to use the gas heater every bit well every bit the oestrus pump if required either to rapidly oestrus upward the pool or if the air temperature is as well common cold to run the heat pump efficiently eg at the and of the swimming flavour.
Attempt to have the water going through the heat pump first and then the gas/oil heater then that the oestrus pump does most of the heating work and the existing banality only needs to "top-up" the temperature
6. Multiple Heat Pumps
For large pools, information technology is possible to run 2 estrus pumps together
or even larger pools can use four heat pumps
Multiple heat pumps can be plumbed in series or in parallel. Delight contact us for advice on the all-time method to apply for your situation.
7. Indoor Heat Pump Installations
Where possible a heat pump should always exist installed outdoors as they need a abiding supply of fresh air to operate and excerpt the heat from. Withal information technology is possible to install some models inside the plant 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 permit the expelled air to escape to the outside.
Recirculation of the expelled air back into the heat pump must be avoided.
For indoor installations, it is likewise necessary to allow air to enter the pump house. A vented door or grille should be installed at the opposite side of the pump house which is sufficiently large to allow fresh air to enter the room at the aforementioned charge per unit that information technology is leaving the room.
For indoor pools, placing the oestrus pump inside the puddle building can assistance to dehumidify the air by drawing fresh air into the pool room and using the rut pump to expel the boiling air.
The disadvantage of this arrangement is that the air temperature inside the pool room volition presently exist reduced to the same equally the outside air temperature. For indoor pools, this may not be desirable and some sort of air heating may then be required negating the benefit of locating the heat pump indoors.
viii. Indoor Pools
Indoor pools take different requirements to outdoor pools, the primary divergence existence the need to dehumidify the moist air and as well to heat the air in winter.
Commonly for indoor pools, the air temperature should be 1 degree warmer than the pool h2o. eg puddle water = 28c, air temp = 29c.
For indoor pools, we exercise 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 us for details.
At that place are ii chief options for indoor pools:-
- Pool heat 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 1 unit of measurement providing air heating, air dehumidification, fresh air inlet and pool water heating. These units need ducting to accident the dehimidified air over any drinking glass windows to forestall condensation from forming.
We can also design a system which is powered by an domestic type air source oestrus pump, feeding a buffer tank
We offer an indoor puddle design service to aid select and specify all of the equipment for indoor pools
See our Indoor Pools folio for more information
9. Heat Pumps for Hot Tubs and Swim Spas
Our heat pumps can also exist installed on hot tubs and swim spas.
Using a rut pump volition normally give greatly reduced running costs compared to an electric heater and the use of rut pump on spas and hot tubs is becoming increasingly popular.
The desired water temperature can be set to a maximum of +40c
The heat pump is simply plumbed into the existing spa excursion
We recommend that the existing electrical heater is retained as a backup heater to the rut pump for extremely cold (sub-goose egg) air temperatures
Ideally the water should flow through the heat pump showtime and so the electric heater second.
Please contact united states of america if yous would similar any advice on incorporating a estrus pump onto a hot tub or swim spa.
