  6. Multiple Heat Pumps For large pools, it is possible to run two heat pumps together or even larger pools can use four heat pumps Multiple heat pumps can be plumbed in series or in parallel. Please contact us for advice on the best method to use for your situation. 7. Indoor Heat Pump Installations Where possible a heat pump should always be installed outdoors as they need a constant supply of fresh air to operate and extract the heat from. However it 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 cut 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 heat pump must be avoided.

  5. Plumbing It is easy to add a heat pump to an existing pool pipework system. First check to see what size of pipes you have. In the UK, these are normally 1.5" or 2" pipes. In Europe, 50mm is more common. Check the writing stamped on your existing pipes and elbows to see which size you have. Do not just measure the external diameter of the pipes or fittings as this is often different to the size required and you may accidentally order the wrong size pipe and pipe fittings ! eg 1.5" pool pipe measures approx 1.9" external diameter (the 1.5" refers to the internal diameter of the pipes for imperial sizes and the external diameter for metric sizes) Once you know the existing pipe size that you have, you will know what size connectors and elbows you will need. In the UK 1.5" pipes are the most common and 50mm in Europe. Please see our Accessories section for a catalogue of pipe fittings. If you have an existing pool heater eg gas or oil boiler, then if it still works ok, we recommend that you leave it in place and put the heat pump in line with the existing boiler. This will allow you to run both the heat pump and boiler if required for a rapid pool heat up. The old heater can also help to supplement the heat from your heat pump in very cold weather to help extend the swimming season.

  If you have a very "sensitive" electrical supply, then some heat pumps have an optional (or built in) "soft-start" option. The soft-start option "eases" in the startup current up to the running current to avoid a power spike on startup. The soft-start kit/option is normally only required for installations using a large single phase heat pump (eg 30kw) with a limited or sensitive electrical supply. In extreme situations, the house lights may flicker or the circuit breaker trips when the heat pump starts up. The soft-start kit helps to prevent this. The soft-start option is not normally required in the UK, or on small heat pumps or on 3-phase heat pumps. Please contact us for further information. We sell a third-party soft start module that can be added to virtually any heat pump. Armoured cable is normally used to supply the heat pump. This is to prevent the cable from being accidentally damaged (eg by digging through it with a spade) The size (thickness) of the cable required depends on the length of cable used. A longer cable run will require 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 allow the power to be easily killed to the heat pump The electrical work should be completed by a qualified electrician who can calculate the cable size required.

  3. Base The base for the heat pump should be level and sound. You can use either a concrete 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 below water level. The only proviso is that the pool circulation pump is powerful enough to deliver the water flow rate that the heat pump needs to operate. We also sell mounting feet and lightweight slabs to mount the heat pump on. These help to raise the heat pump off the ground and also reduce noise and vibration. While the heat pump is operating, it is normal for condensation water to drip from it - particularly in humid conditions. You should consider the condensate water that will come from the unit in the base design as the amount of water can be considerable and cause a pool of water to form. For example if the unit is mounted on timber decking, holes can be made in the decking to allow the condensate water to drain away and not cause rotting to the timber. Some

  Duratech Type Heat Pump Required Clearances Pool heat pumps should wherever possible be installed outdoors in order to have a good supply of fresh air. However some can be installed inside a pump house - see the section below. Try to locate the heat pump close to the pool pump to minimize the friction in the pipes. If your pipe run is too long, you may have an insufficient water flow rate through the heat pump and may need to upgrade your pool pump or use larger diameter pipes to and from the heat pump to reduce friction in the pipes and maintain a good water flow rate. Most heat pumps state the nominal water flow required on their specification charts. If the water flow through the heat pump is too low, then the heat pump may overheat and the safety mechanism will turn the unit off. Not Like This - Hall of Shame ! Some examples of incorrect swimming pool heat pump installations. Insufficient Clearances on 3-sides if heat pump Insufficient clearan

• Installation of Swimming Pool Heat Pumps(part 1) 2019-10-22

  Installing your pool heat pump is a fairly simple task and can be completed either by the pool owner, a local engineer or by one of our experienced installation engineers. The manufacturer's recommendations should however always be followed in order not to invalidate the warranty, or to prevent your heat pump from working properly. Here are some tips if you decide 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 flow of air. Optimum efficiency of the heat pump relies on good air flow. Where possible the heat pump should always be installed outdoors so it can receive a good supply of fresh air to operate and extract the heat from. Make sure that the air being expelled by the fan will not hit any obstacles and could be recirculated back into the heat pump. Pool heat pumps, come in two main formats - vertical fan and ho

• Why Choose Heat pump with Hydronic Heating in your Home? 2019-06-28

  When the cold hits in winter, your first instinct is to turn up the heating, but that usually results in a huge power bill in the spring. Unfortunately for most people, it`s a choice between paying these power bills or feeling uncomfortably cold during the winter months. Floor heating system (Heat pump+ hydronic heating) is a solution that works well for many home owners. The working principle of the floor heating system is to use the circulating hot water laid in the closed pipes below the floor to distribute heat evenly in the whole room. The circulating hot water needed in the system can be heated with any energy, such as traditional gas fired boilers, heat pump units, and renewable energy sources such as ground source heat pumps and solar energy. -- What is floor heating? It is understood that low temperature radiant floor heating is heated through the floor under the heat pipe - aluminum-plastic composite pipe or heating cable, the floor heating to the surface temperature of 18 to 32 degrees, even to the indoor radiant heat floor heating to achieve heating effect. Compared with the traditional heating method, we can say that there are several advantages: First, the temperature is uniform

• Part 2:Comparison of Air Source Heat Pump, Ground Source Heat Pump and Water Source Heat Pump 2019-06-08

  Water Source Heat Pumps Water source heat pump is an air-conditioning technology that uses solar energy resources stored in earth water as cold and heat sources for energy conversion. By inputting a small amount of high-grade energy (such as electric power), the transfer of low-temperature thermal energy to high-temperature energy can be realized. Water is used as heat source of heat pump heating in winter and cold source of air conditioning in summer. That is to say, heat in buildings is "taken out" in summer and released into water. Because of the low temperature of water source, heat can be efficiently taken away to achieve the purpose of indoor cooling in summer. In winter, heat energy is "extracted" from water source by water source heat pump units and sent to buildings for house heating. Shallow water sources on the earth's surface (generally less than 1,000 meters), such as groundwater, surface rivers, lakes and oceans, absorb considerable radiation energy from the sun into the earth, and the temperature of water sources is generally very stable. Above are the heat sources and working principles of the three heat pump products, and following are their operating conditions. Air source heat pumps are suitable for places with air. Based on the current technology, they can be used in areas above minus 25℃ for hot water, heating and cooling. Ground source heat pumps are suitable for single vill

• Part 1:Comparison of Air Source Heat Pump, Ground Source Heat Pump and Water Source Heat Pump 2019-06-07

  New energy has developed rapidly in recent years, and many people show great interest in this. In this article, we will compare and distinguish air source heat pumps, ground source heat pumps and water source heat pumps, which are of great interest and most concern to us. Air Source Heat Pump Air source heat pump utilizes the energy in the ubiquitous air as the main power, and drives the compressor to run through a small amount of electricity to realize energy transfer. Air source heat pumps do not need complicated configuration, expensive water intake, recharge or soil heat exchanger systems and special machine rooms. They can gradually reduce the emission of pollutants to the atmosphere caused by traditional heating, and ensure heating efficiency while taking into account the purpose of energy saving and environmental protection. Ground Source Heat Pumps Ground source heat pump utilizes shallow land energy which transfers from low-grade heat energy to high-grade heat energy by inputting a small amount of high-grade energy (such as electricity). Geothermal heat pump belongs to a type of heating and air conditioning system which uses the shallow geothermal resources on the earth surface as the cold and heat source. Shallow surface geothermal resources (also called geothermal energy) refer to the low-temperature potential heat energy stored in the surface soil, groundwater

• OSB Air Source Heat Pumps as Hot Water Heaters for Villas 2019-06-06

  As any who has lived in a villa knows, it does not only cover a large area, but also has many bathrooms and taps. Therefore, the villa's hot water equipment should not only be stable and comfortable, but should also ensure a large amount of multi-point water supply. In the past, villa owners often chose solar water heaters. The installation requirements of solar water heaters are relatively high (for example, sun facing and requiring a large area to place heat collectors), but because villas have their own roofs, this is not troublesome for villa owners at all. In recent years, because of the inconvenience of solar water heaters (such as the high requirement for light when heating cold water, easy to freeze in winter, too small hot water volume, large temperature difference between day and night), villa owners have been looking for better and more comfortable hot water heating alternatives. In this context, air source heat pumps have come to the view of villa users. Air heat pumps need to absorb a large amount of free heat from the air when heating. Therefore, they are especially suitable for being installed in well-ventilated places with a sunny exposure, such as on the roof of villas. Like solar water heaters, air source hot water heat pumps belong to environment-friendly products. When they are used, there will be no exhaust gas or open fire, thus no gas poisoning or other accidents. Meanwhile, unlike solar water heaters, air to water heat pumps are not affected by weather, season and other factors. Air source heat pumps ca

• Part1:Are the Energy Costs Too High to use air source heat pump for indoor heating? 2019-06-05

  Some users complain that the power consumption of their air source heat pump for house heating is very high, not as energy-saving as advertised! In fact, there are many factors affecting the power consumption of heating, such as building insulation, heat pump quality and selection, heating ways, user's operating habits and so on. It would be unwise to only put the blame on the air source heat pump. Thermal Insulation of Your House The energy consumption of air source house heating, first of all, must be related to the building's enclosure structure, doors, windows, storey height, wall insulation and so on, which are important factors. If the window is made of large and single-layer glass, then the heat dissipation is relatively much higher and more heat supplement is needed. In the selection of the heat pump, you should consider higher value of heat load. The higher the room height, the greater the heat dissipation. For the same wall, there is a great difference between thermal insulation and non-thermal insulation. In addition to these, balcony orientation and wind speed will also affect the building's demand for heat. Heat Pump Quality Whether the product design is reasonable, what the components are like and how the workmanship is, will have an impact on energy consumption. For example, the reasonable defrosting logic of air source heat pump should be: defrosting thoroughly only when there is frost. If the design is not reasonab
