Can be scanned quickly easily: no input from Eire, perfect as normal.
This one caught my eye:
there are example for PV, Solar Thermal, MHVR etc

According to these experts, the most common problems related to the quality of the works in domestic heat pump installations in France are:
 Oversizing of the heat pump capacity in the case it has been chosen by the installer (i.e. without detailed study of the heating needs).
 Too low quantity of refrigerant inside the appliance.
 No technical documentation provided to the user about the installation (technical documentation of
the heat pump, drawings of the hydronic circuit, electrical diagram of the installation).
 No information provided to the user about the commissioning of the installation.
 For air to water heat pumps:
 wrong positioning of the outdoor unit, with insufficient passage for the fresh air and/or recycling of the fresh air flow;
 absence of a drain to evacuate condensates;
 in some cases, no electrical connection of the electrical heating backup electrical resistance;  wrong adjustment of the defrosting cycle times.
 For water to water heat pumps:
 undersizing of the primary circuit water pump or too low primary water flow rate.
 For ground source heat pumps:
 undersizing of the surface of the ground collectors.

MVHR done well, works well, which is pretty much the same for all building work
