E-SI installs Guernsey’s first modulating ground source heat pump in March 2010

E-SI installed the first modulating ground source heat pump in Guernsey in March 2010.  One has been installed previously in Jersey.

E-SI uses Mitsubishi heating equipment, which is extremely energy efficient.

A modulating ground source heat pump alters the output power to speed up or slow down according to how much heat is required in the home and how cold or warm it is outside. Tied with E-SI’s Dataterm Intelligent Heating Controls, which ‘optimises’ the start times of the heating set points, this combination makes for an extremely efficient and economic system.  The system has very low running costs, low long-term bills, a small carbon footprint, and it can be powered by locally generated electricity. Photovoltaic cells can offset all of the heating energy required over the year.
