  • Servicing warranty


Nicholls Boreholes were selected by ProMep Ltd, to design, supply and install a 11kW Vaillant heat pump system into a brand-new build with the living area above ground and the bedrooms in the basement.

About the project

For this system we drilled 2 boreholes to 125 metres in the garden.  The heat pump supplies heating and hot water.

As an MCS Accredited Installer, we are able to design, supply and certify the system so the Client is now claiming the  Domestic Renewable Heating Incentive (RHI) feed-in tariff and receiving substantial quarterly payments over 7 years from the Government.  As a Vaillant approved installer, we were able to service and offer a 7 year parts and labour warranty on this system.
