INTRODUCTION
You can find more information on our web, so please take a look.
Electricity Prices rose up significantly in many Canadian Provinces and US states. This rising utility rates trend will continue in the future, since federal / local governments are gradually pushing citizens to consume less and less Energy by tightening energy efficiency requirements in every new version of building code. This is a major challenge for both home owners (or to be home owners), designers, contractors and equipment suppliers since they must come up with new products in order to meet up with the higher sustainability standard.
With many Canadians spending more time at home due to long winter, COVID-19 Pandemic and aging population, demand for natural light in indoor spaces is on the rise. More natural light means larger Fenestrated Building Envelopes which require more and more energy to provide an acceptable indoor living standard.
With Rising Energy Prices, tougher Environmental Regulations combined with demographic and living standard changes, Air to Water Heat Pumps are the most affordable answer to the previously listed requirements. Air to Water Heat Pumps are HVAC devices (called Mini Air Cooled Chillers in Europe) producing Chilled/Hot Water (or Water/Glycol Mixture) that can be used for Space Heating and Cooling as well as Domestic Hot Water (DHW) Heating. ATW Heat Pumps are equipped with a DC Inverter Compressor and the Split Configuration has the EVI (Enhanced Vapor Injection) technology, which make them able to operates at a temperature range from -25°C to 45°C
AIR TO WATER (ATW) HEAT PUMPS CONFIGURATIONS
Monoblock Air to Water Heat Pump
Monoblock ATW Heat Pump is comprised of one piece destined to be installed outside. When used in outdoor climates with peak winter temperatures below 0°C (32°F), a Propylene Glycol/Water Mixture shall be used as a heat transfer fluid to avoid freezing. Mixture Glycol Concentration % depends on lowest winter temperature. In most major Canadian Cities a 50% Water / Propylene Glycol Mixture is used.
Monoblock ATW Heat Pump requires external pump for pumping heat transfer fluid (whether Water or Water/Glycol Mixture). In Winter time, Monoblock ATW Heat pump goes into cooling mode (in other terms it draws heat from the indoor space) to defrost the ice accumulated on its evaporator. Monoblock Heat Pump requires an external heat source for its defrost operation in winter. Controller of this type of Heat Pump supports modulating speed pumps and is equipped with a PWM (Pulse Width Modulation) control signal for controlling fluid circulation pump speed.
Split Air to Water Heat Pump
Split ATW Heat Pump is comprised of two pieces. One piece called the outdoor unit is destined to be installed outside and the second piece, called the indoor unit is destined to be installed inside. Split ATW Heat Pump does not require Water/Glycol Mixture in cold climates, since the link between indoor and outdoor unit is made by refrigerant copper lines (refrigerant is a fluid that does not freeze).
Split ATW Heat Pump controller is equipped with a PWM (Pulse Width Modulation) control signal for controlling fluid circulation pump speed. Variable Speed Pump helps increasing the energy efficiency of the heat pump and improve summer performance when heat pump goes into humidity control mode. In Winter time, Split ATW Heat pump goes into cooling mode (in other terms it draws heat from the indoor space) to defrost the ice accumulated on its evaporator. It also requires an external heat source for its defrost operation in winter.
ATW Configurations Cost Analysis
Air to Water Heat Pump can be used to provide either Chilled Water or Hot Water and Pre-Heated DHW or Chilled Water and Hot Water and Pre-Heated DHW. In both cases price difference is driven by machine, glycol, pump and manpower individual prices.
Heating or Cooling with DHW Pre-Heating
Simultaneous Heating and Cooling with DHW Pre-Heating
The above schematics depict the 2 most common installations of Air to Water Heat Pumps. The one on the left is for places where simultaneous Cooling / Heating is rare, so one tank with indirect coil is used to preheat DHW to temperatures as high as 130°F (or 55°C) and the other tank is used for either space heating or space cooling. In the schematic on the right, One indirect tank is used for DHW pre-heating and space heating and the other tank is dedicated for chilled water.
When Heat Pump are used to serve largely Fenestrated Properties with a South and North Exposures, area beside the southern façade could have a cooling demand (even in mid-winter temperatures) and area beside the northern façade will have a heating demand.

CONCLUSION
Even though Monoblock Heat Pumps are cheaper than the split ones, Complete Installation of Split ATW heat pump is always cheaper to customer. Assuming that water is free to be used as a heat transfer fluid in Split Heat Pumps installations, the cost of buying a good quality glycol with proper inhibitor concentration as well as the cost of circulation pump make the Monoblock heat pump installation more expensive.
Monoblock Heat Pumps are more popular among DIY customers because people think it's cheaper (before calculating the overall cost of the project) and is easier to install (plug and play device). Split ATW Heat Pump requires a professional for the installation and commissioning of the refrigerant copper lines which makes it not appealing to some DIY Customers.
Air to water heat pumps provide an eco-friendly solution to heating our homes. Air to water heat pumps work by transforming energy in the outside air into usable heat, helping to reduce heating bills by up to 60% and cutting CO2 emissions by 50%. You can read more about this innovative heating method in our previous article on how does an air to water heat pump work.
There are two main types of heat pump that you&#;re likely to have heard of before. These are &#;split heat pumps&#; and &#;monobloc heat pumps&#;. There&#;s often a lot of confusion as to what exactly the difference is between these two heat pumps. That&#;s why we&#;ve put together the following short and simple guide, detailing the main differences between the two, and which is the best option for your home.
A monobloc heat pump is a single unit heat pump that&#;s located outside of the home. It consists of a singular outdoor unit in which the compressor, heat exchanger and water side of the refrigeration cycle is contained.
As you might guess from the name, a split heat pump, unlike a monobloc heat pump, uses more than one unit. A condenser collects heat from the air and sends the heated gas to an indoor unit that is located inside the home. This is where the hot gas that&#;s been transported in, is used to heat the water. The indoor unit also houses your hot water cylinder.
The main difference between split vs monobloc heat pumps is the setup and units required. Whilst a monobloc heat pump only requires a singular outdoor unit, a split pump requires both an indoor and outdoor unit. A monobloc heat pump heats the water outside, whereas with a split system, the heated water is all contained inside the house.
When it comes to choosing between a split vs monobloc heat pump, it really depends on the individual requirements of your property. Monobloc heat pumps are cheaper to buy and easier to install, however they will be more expensive to run as the heat pump has to work harder to heat the water from the outside and transport it in. As a split unit is contained within the building it is cheaper to run, and the outdoor unit is usually smaller and quieter. However, the system is usually more complicated to install.
So ultimately, deciding between a split vs monobloc heat pump depends on your budget and the space and layout of your property. Our knowledgeable team at Pipelife are always happy to help advise you on the best option for your home.
We offer both split and monobloc heat pumps to cater for individual homeowner requirements. These are:
The Yutaki S heat pump consists of an exterior inverter unit that is connected to an interior hydraulic unit. When in heating mode, the exterior unit absorbs heat from the outside (at temperatures as low as -20 °C), and transfers it to the water cycle via the interior hydraulic unit.
What&#;s particularly special about this air to water heat pump is that it also has a cooling mode for use during the summer. Working in the opposite way, it can draw heat outwards towards the exterior. Highly effective in producing hot/ cold water to supply radiators, fan coil units, underfloor heating or a combination of these, the Yutaki S heat pump is a versatile option. When connected to a tank, it can also be used to produce domestic hot water.
An integrated system that provides heating and cooling as well as domestic hot water, the M Thermal heat pump is a year-round solution that can replace the need for traditional gas/ oil boilers or work alongside them. A compact, single unit is installed on the outside of the property and the heat pump is connected to the indoor heating system using two insulated pipes and the electronic connection cables under the ground.
Available in single-phase capacities of 4KW to 16KW, or three-phase capacities of 12KW to 30KW, the M Thermal heat pump is a fuss-free, not to mention an efficient, solution for heating your home.
