These heat pump water heaters use the same operating principle as an air conditioner or domestic refrigerator.
Water to air heat pump schematic.
If either flow stream is restricted the heat pump quickly shuts itself off due to refrigerant pressure limits.
These units work in a similar manor but without the reversing valve.
Types of heat pumps air source heat pump systems.
Both zones must operate in the same mode e g heating or cooling at the same time.
A hydronic heat pump has many advantages over conventional air to air heat pumps.
Air to air heat pump systems.
Figure 1 shows a piping schematic for an air to water heat pump system that provides zoned heating using radiant panels and zoned cooling dehumidification using small air handlers.
The high pressure high temperature vapour refrigerant leaves the compressor but this time heads into a plate heat exchanger.
Flow starvation can occur when the heat pump serves a zoned hydronic distribution system.
Therefore increasing the surface area of your emitter system larger radiators and or underfloor heating and minimising the heat loss wherever possible.
The arrangement in figure 13 is a series configuration and the heat pump evaporator is supplied with energy from the solar system.
Colmac heat pump water heaters.
An air source heat pump absorbs warmth from outdoor air and transfers it inside your home.
The industry s only water source heat pump with automatic 3 speed fan control provides greater and more versatile comfort control than its 2 speed counterparts an economical approach for comfort conditioning requirements in both traditional and geothermal replacement renovation and new construction applications.
As can be seen energy from the storage unit is directly supplied to the building when the temperature of the water in the storage.
By storing the heat energy we can distribute it to any source we want such as a domestic hot water heating and cooling fans finned radiators hydronic in floor heating.
By moving heat indoors the heat pump system causes your interior areas to feel warmer.

Colmac heat pump water heaters offer commercial and industrial users of sanitary hot water an energy efficient means of heating water to temperatures as high as 185 f 85 c in a single pass.
Even if it s cold outside abundant warmth still exists in outdoor air.
Domestic heaters that are powered by oil gas and electricity heat water up to around 70 80 c whereas ground or air source heat pumps used for hot water may only be efficient up to 55 c.
