Subscribe to our YouTube ChannelThe main differences between integrated and split heat pump hot water systems are efficiency, cost, maintenance, environmental effect, installation, and structure.
Split heat pumps have a separate, bigger compressor that allows faster hot water generation, making them more efficient. Integrated systems can look attractive and are space-saving.
Split systems are generally cheaper but require longer install times, while integrated systems are more plug-and-play. Integrated systems also are smaller and therefore use less refrigerant. Some split models, such as the one from Reclaim, now use CO2 as a refrigerant which is not damaging the ozone layer and is less toxic than other refrigerants.
Two main options exist for this technology, raising the question of whether to choose a split or integrated hot water heat pump.
Unfortunately, since there are decent Federal Government rebates available, extremely cheap gear is on the market so make sure you do your research before making a purchase. So environmentally, this Federal Government rebate &#; designed to help the environment &#; actually harms the environment with all the waste of cheap crappy gear &#; it creates.
Unfortunately, the second time around, you will not be getting the rebate again &#; so you will need to fork out a substantial amount of money. We, therefore, recommend getting a decent heat pump hot water system in the first place and paying some funds in addition to the rebate to secure better long-lasting gear.
Hot water-generating heat pumps have many advantages over traditional hot water tanks, be it gas or electric, such as:
They can cost more than a standard electric tank hot water system, and their installation is more complicated than a standard tank. Nevertheless, the cost savings regarding running costs over time and the environmental benefits outweigh these disadvantages.
Now that you have decided to get a heat pump, one might wonder if the integrated hot water heat pump (all in one) or a split hot water heat pump (outdoor unit and tank are separated) is the better option. The main differences between the two systems are in efficiency, cost, maintenance, environmental effects, installation and size.
Split system hot water units have a separate, bigger compressor than integrated hot water heat pumps with the compressor on the tank. The larger the compressor for a hot water system, the faster the system can generate hot water. By default, a split hot water heat pump generates more hot water in a shorter period.
If your household has a high usage of hot water, then it&#;s recommended that you consider a split hot water heat pump system. However, an integrated hot water heat pump system with a smaller compressor will do the job if your household is relatively small.
Split system hot water heat pumps are a technology that has been around a little longer than integrated systems. Often they also come with a lower price tag. Integrated hot water heat pump systems tend to have advanced technology, which aims to use the available space as efficiently as possible to streamline hot water production.
Like an air conditioner, split system hot water heat pumps require maintenance after a few years. This could include refilling the refrigerant and replacing the seals.
Integrated systems claim they require less maintenance as their technology makes refrigerants less likely to evaporate. On the other hand, any electronic equipment can benefit from a check-up after 3 to 5 years. Therefore both technologies will need this support.
Both systems also require homeowners to clean out their compressor filters at least once a year which is a simple process.
Many refrigerants in heat pumps can be toxic to our environment. Although there have been improvements to decrease their impact on the environment in recent years, they are still harmful.
Some more modern hot water heat pumps, such as the Reclaim model, use CO2 as their refrigerant. As CO2 is a naturally occurring gas, the environmental effects of this particular product are superior to heat pumps using greenhouse-generating or ozone-depleting gases.
Since the system is &#;split&#;, there are extra steps to install all the components to work seamlessly together. Firstly, the compressor and the tank are installed. After the connection work has been completed, a refrigerant pipe is installed to connect the tank and the compressor. After this, the refrigerant is then placed in the pipe.
In contrast, integrated heat pump systems are more of a plug-and-play variety and often only require the installer to connect the water pipes correctly.
The integrated units require a little less space, as one is installing only one unit, similar in size to a tank, instead of the separate hot water tank and the outdoor unit. On the other hand, the integrated units are usually a little taller, as they have the heat pump sitting on top of the tank.
Both systems offer the flexibility to install your hot water systems close to your water supply. They can have different-sized compressors and tanks, meaning families of many sizes can use both types easily.
Both integrated and split heat pump systems offer unique benefits, and we have created a summary of both types below.

Air-to-water heat pumps excel at whole-home heating, efficiently providing warmth to multiple rooms, making them ideal for open-concept spaces. In contrast, mini-splits are perfect for single rooms, offering targeted temperature control. Both options are excellent for your HVAC and heating systems.
Installation considerations are crucial, especially for single-zone heat pumps. Mini-splits, a type of single-zone heat pump, are relatively easy to install. On the other hand, geothermal heat pumps, also known as ground source heat pumps, require a more complex setup due to the water connections involved. Despite this, both options offer energy-saving capabilities that can help reduce your power bills for whole-home heating.
So, which should you choose: air conditioners or home heating systems? It depends on factors like room size, desired temperatures, and operational costs. Consider these aspects before making a decision that best suits your specific HVAC needs.
Air source heat pumps and mini-splits are popular options for heating and cooling single-zone houses. However, they have key differences in terms of operation and energy consumption. Understanding these differences can help you make an informed decision when choosing the right system for your needs.
One of the main differences between air source heat pumps and mini-splits is how they extract heat. Air source heat pumps work by extracting heat from the outdoor air and transferring it inside the house to provide warmth during colder months. This makes them highly efficient, as they utilize existing heat rather than generating it from scratch. The external unit of a central air source heat pump contains the necessary components to extract this heat efficiently.
Mini-splits, on the other hand, transfer heat directly to indoor units without relying on outdoor air extraction. They use refrigerant lines to move warm or cool air directly into specific zones within a building. This allows for individualized temperature control in different areas, making mini-splits an excellent choice for multi-zone heating or cooling.
Unlike air source heat pumps, which typically require ductwork to distribute conditioned air throughout a home, mini-splits are ductless systems. Each indoor unit conditions the air in its specific zone, offering several advantages:
- Greater flexibility in installation since there's no need to retrofit existing ductwork or build new ones.
- Individualized temperature control in different areas of a building, allowing occupants to set their preferred temperatures independently.
Both air source heat pumps and mini-splits can provide cooling during hot summer months. However, air source heat pumps are designed to provide both heating and cooling, making them versatile options for year-round comfort. They can extract heat from the outdoor air even in freezing temperatures, making them ideal for colder climates. In summer, they operate in reverse, extracting heat from inside and releasing it outdoors to cool the building.
Mini-splits are primarily used for cooling or supplemental heating. They excel at providing targeted cooling in specific areas or supplementing existing heating systems in cooler months. Their efficiency in cooling and ability to provide supplemental heating make them a popular choice for many homeowners.
In conclusion, air source heat pumps are suitable for comprehensive heating and cooling throughout a home, while mini-splits offer targeted temperature control and flexibility, making them ideal for specific zones or supplemental use. Consider your specific needs, such as room size, desired temperatures, and installation constraints, when choosing between these systems.

Ductless mini-splits and air-to-water heat pumps are two popular options for heating and cooling systems in residential and commercial buildings. While both systems serve the purpose of regulating indoor temperatures, they differ in their mechanisms and applications.
Ductless mini-split systems, also known as ductless air conditioning systems, operate by using refrigerant to cool or warm indoor spaces. These systems consist of an outdoor unit connected to one or more indoor units, allowing for zone control capabilities. Each indoor unit can be independently controlled for personalized comfort in different areas.
Mini-splits are particularly suitable for smaller spaces or single rooms where a centralized air conditioning system may not be necessary. They offer flexibility in installation since no ductwork is required, making them a great option for retrofitting older buildings or adding climate control to specific areas. Mini-splits consist of indoor air handling units and an external air source heat pump unit.
Air-to-water heat pumps work by circulating heated water through radiators or underfloor heating systems in a home. Unlike mini-splits, which use refrigerant, these systems transfer heat from the outside air to water that circulates within the building.
Air-to-water heat pumps are commonly used in larger buildings and homes where centralized heating is preferred. They can efficiently provide warmth throughout multiple areas by utilizing a network of radiators or underfloor pipes. This type of system is often favored in colder climates as it can generate consistent and comfortable heat even during extreme weather conditions.
While both mini-splits and air-to-water heat pumps have their advantages, it's important to consider the specific needs of your home when choosing between them. Here are some key factors to consider:
