GROUND SOURCE & Air SOURCE HEAT PUMPS -
(Energy efficient heating for low pressure hot water)
Ground Source and Air Source Heat Pumps are becoming more popular!
Certikin's H & V department can offer bespoke sizing of these units for pool applications and advise on capability of existing and new Calorex ducyed units for use with renewable energies.
Producing Hot Water for the majority of domestic and commercial applications has historically been by way of burning fossil fuels. The result of producing hot water by fossil fuelled heaters (however efficient), is to produce CO2. Most people are now aware of the detrimental affects of CO2 on our environment, and the need to seriously consider climate friendly alternatives. In addition to their vast range of climate friendly units, Calorex have now introduced two types of equipment for providing LPHW (Low Pressure Hot Water) which significantly reduce CO2 emissions, reduce running costs and require minimal maintenance.
The two types of equipment available, each harnessing the earth's resources are:
1. Ground Source Heat Pumps
2. Air Source Heat Pumps
Both will be welcomed by many Local Authorities now insisting on "renewable energy" heating systems for compliance with new building design requirements. Furthermore, these provide an ideal alternative for supplying LPHW to Calorex Air Handling Units.
GROUND SOURCE HEAT PUMPS
This method utilises heat collector pipework which absorbs energy from beneath ground level. Heat collector pipework is buried within the earth's strata; either horizontally in relatively shallow excavations, or vertically within circular bore holes.
For both versions, this heat collector pipework is connected to efficient water-to-water heat pump(s), where the absorbed energy is considerably upgraded and transferred to the LPHW circuit. This provides a constant supply of hot water.
AIR SOURCE HEAT PUMPS
Air-to-water heat pumps have successfully been installed for many years, especially for providing efficient pool water heating. This equipment absorbs energy from the external air rather than from the earth's strata; therefore eliminating the need for heat collector pipework.
Again, the absorbed energy is considerably upgraded and transferred to the LPHW circuit using efficient heat pump technology.
HEATING SYSTEM OPTIONS
Both ground and air source equipment can either be installed for sole provision of LPHW heating (known as a Monovalent system), or in conjuction with more traditional heating methods such as boilers, known as a Bivalent system.
A "buffer" tank is needed to assist with the demands of the hot water system. The LPHW can also be upgraded in temperature, if necessary, by independent heating (by others). Typical LPHW temperatures available from both Ground Source and Air Source Heat Pumps range from 35C - 55C, although 65C can be acheived with Air Source units (under certain conditions).
