Heat pumps produce heat without any
combustion process, with better energy efficiency
than condensing boilers. The heating process is
based on a refrigerant gas which transports heat
along a closed circuit. Most of these refrigerant
gases present environmental risks and are
expensive. This is why it is necessary that these
heat pump systems be properly started and
maintained. 

Heat pumps require thorough and regular
monitoring to maintain optimal efficiency, reduce
the risk of refrigerant gas loss, and ensure
reliable and long-lasting operation. The
maintenance and upkeep of these installations is
an important activity in the HVACR market.

Generally, annual maintenance is recommended
for all heat pumps. It ensures efficient operation,
detects possible refrigerant gas leaks and
optimizes efficiency to reduce energy costs.

When carrying out maintenance work on domestic
heating systems, measuring the differential
pressure is one of the mandatory measurements
to be carried out. This includes : 

Measuring gas pressure and static pressure of a
boiler
Draft Measurement: Measuring the pressure in
the combustion chamber or chimney/flue to
ensure that combustion gases are exiting the
combustion equipment properly and safely.

Measuring gas flow and static gas pressure in the
system is particularly important, because the
burner can only operate properly within a
specified flow pressure range. Outside of this
range, explosive flame formation may occur. The
consequences are malfunctions or even
breakdown of the heating system. For this
reason, acquiring a reliable and easy-to-use
differential pressure measuring instrument is
essential.

For a heating system to operate efficiently and
distribute heat as evenly as possible, measuring
temperature is crucial. At Sauermann you will find
instruments for directly measuring the
temperature on heating equipment or in the
ambient air of a room.

Heat pumps and combustion heating systems can
suffer seriously from refrigerant and combustible
gas leaks. Most refrigerants are potent
greenhouse gases and can seriously harm the
environment, while leaking combustible gases
pose serious safety concerns (explosion hazards)
and waste fuel. It is therefore essential to be able
to easily locate any leak in order to quickly repair
or replace the segment of the gas circuit
concerned. 

Searching for and finding gas leaks can be very
difficult. Fast professional leak sniffers are
essential for precisely and quickly locating the
slightest leaks in a gas circuit.
