Heat Pump Pre-Installation Checklist

Where applicable, the following should be considered before commencing with the installation of
the heat pump:

Description

Checked

Heat pump is correctly sized

Full heat loss and design calculations to BS 12831.
Anti-Freeze Protection – Glycol

Without adequate glycol protection down to -15°C the guarantee of the heat pump

will be invalidated. All glycol should pre-mixed in an appropriate container as per

manufacturers’ instructions and pumped into the system. Hand pumps are not

suitable. Glycol recommendations are; Fernox HP5c, Sentinel R700 and R600.
Glycol Discharge Vessel

Required to collect fluid discharged via a PRV. Article Number: 0020145563

Y-Strainer / Dirt Filter

Recommended to be fitted on the return to the heat pump. The use of a magnetic

filter is also recommended.

DHW Cylinder with Adequate Coil Rating

When non-Vaillant heat pump DHW cylinders are used, it is recommended using

cylinders with coil rating of minimum 4kW per 1m

Correctly sized heat emitters for MCS SCoP rating:

Heat emitters may need over sizing depending on the flow temperature from the

heat pump. Underfloor heating will need designing with pipe centres correlating to

the flow temperature.

Vaillant Controls

Correct controls are chosen for the operation of heating zones and DHW: See

appropriate schematic.

Party Controls

When utilising input from 3rd party controllers, Vaillant controls will require a ‘NC’

operation for the input terminals; the heat pump will start running when there is an

open circuit across the terminal. Where it is not possible for a 3rd party controller to

provide this, a relay can be used; most recognisable ones being ‘230V 8 pin Relay’

(DPDT).

Fill and isolation points for all circuits are considered.
Hybrid Systems

Relevant heat and electrical meters are considered when claiming RHI.
